"Invalid Certificate Signing Request" error when generating MDM Push Certificate
Hello, I am currently developing an MDM solution, including both the sever-side(.NET) and the client app. I have recently been granted the "MDM CSR" signing permission in the Certificates, Identifier & Profiles of my developer account. I am following the official Apple documentation, "Setting up Push Notifications for your MDM Customers," to generate the required MDM Push Certificate. However, I keep encountering the "Invalid Certificate Signing Request" error when uploading the encoded .plist file to the Apple Push Certificates Portal(identity.apple.com/pushcert). The steps I have taken so far: Generated .csr file via Keychain Access Used the MDM SCR certificate to sign the request. Created a .plist file for th final upload containing : Customer CSR: Base64 encoded Signature : Signed using the SHA256withRSA algorithm and Base64 encoded. Certificate Chain : Including my MDM Vendor Signing Certificate, the Apple WWDR intermediate certificate, and the Apple Root CA. Issues/Questions: Is there a specific requirement for the order of the certificates in the chain? Are there common pitfalls regarding the .plist structure or the encoding of the signature that might cause the "Invalid CSR" error? Is there a tool or a specific validation step I can use to verify the integrity of the generated .plist before uploading? I have double-checked the encoding and the signing process, but the portal continues to reject the request. Any insights or guidance from community would be greatly appreciated. Thank you in advance for your help!

Fatal error on rollback after delete
I encountered an error when trying to rollback context after deleting some model with multiple one-to-many relationships when encountered a problem later in a deleting method and before saving the changes. Something like this: do { // Fetch model modelContext.delete(model) // Do some async work that potentially throws try modelContext.save() } catch { modelContext.rollback() } When relationship is empty - the parent has no children - I can safely delete and rollback with no issues. However, when there is even one child when I call even this code: modelContext.delete(someModel) modelContext.rollback() I'm getting a fatal error: SwiftData/ModelSnapshot.swift:46: Fatal error: Unexpected backing data for snapshot creation: SwiftData._FullFutureBackingData<ChildModel> I use ModelContext from within the ModelActor but using mainContext changes nothing. My ModelContainer is quite simple and problem occurs on both in-memory and persistent storage, with or without CloudKit database being enabled. I can isolate the issue in test environment, so the model that's being deleted (or any other) is not being accessed by any other part of the application. However, problem looks the same in the real app. I also changed the target version of iOS from 18.0 to 26.0, but to no avail. My models look kind of like this: @Model final class ParentModel { var name: String @Relationship(deleteRule: .cascade, inverse: \ChildModel.parent) var children: [ChildModel]? init(name: String) { self.name = name } } @Model final class ChildModel { var name: String @Relationship(deleteRule: .nullify) var parent: ParentModel? init(name: String) { self.name = name } } I tried many approaches that didn't help: Fetching all children (via fetch) just to "populate" the context Accessing all children on parent model (via let _ = parentModel.children?.count) Deleting all children reading models from parent: for child in parentModel.children ?? [] { modelContext.delete(child) } Deleting all children like this: let parentPersistentModelID = parentModel.persistentModelID modelContext.delete(model: ChildModel.self, where: #Predicate { $0.parent.persistentModelID == parentPersistentModelID }, includeSubclasses: true) Removing @Relationship(deleteRule: .nullify) from ChildModel relationship definition I found 2 solution for the problem: To manually fetch and delete all children prior to deleting parent: let parentPersistentModelID = parentModel.persistentModelID for child in try modelContext.fetch(FetchDescriptor<ChildModel>(predicate: #Predicate { $0.parent.persistentModelID == parentPersistentModelID })) { modelContext.delete(child) } modelContext.delete(parentModel) Trying to run my code in child context (let childContext = ModelContext(modelContext.container)) All that sounds to me like a problem deep inside Swift Data itself. The first solution I found, fetching potentially hundreds of child models just to delete them in case I might need to rollback changes on some error, sounds like awful waste of resources to me. The second one however seems to work fine has that drawback that I can't fully test my code. Right now I can wrap the context (literally creating class that holds ModelContext and calls its methods) and in tests for throwing methods force them to throw. By creating scratch ModelContext I loose that possibility. What might be the real issue here? Am I missing something?

Remove Unused Network Links
Apple MacOS Sequoia 15.4.1 Creates a ton of unused network interfaces and it's a nightmare trying to figure out what they all do, what theyr're linked to, etc. It appears that network links utun0, utun1, utun2, ... are never used or useful. ip link shows they are all status UNKNOWN. I don't use a VPN or anything like that, and the documentation on these interfaces does not exist. I'd like to permanently delete them and permanently prevent them from ever being created again -- how can I accomplish this task?

iOS 26.4: Receipt of previous transaction is returned
Hi, We are facing issue with purchases on iOS 26.4. The app store receipt received is from previous transaction leading to receipt validation failures. There are some purchase success observed for pending transactions but success rate for pending transactions is also very low. We are using Unity In-App Purchasing (IAP) 4.13.0. Let us know for any more details and any fix / workaround available. Thanks.

Unwanted Communication Reporting Extension deletes messages always
I am implementing an Unwanted Communication Reporting Extension (IdentityLookupUI) to allow users to report spam messages to our backend. The extension works perfectly in terms of data collection and network reporting (using ILClassificationExtensionNetworkReportDestination). However, I’ve encountered an issue with the message lifecycle: whenever the user taps "Done" and I return a response, the system automatically moves the reported message to the Recently Deleted folder. I want to report the data but keep the message in its current folder (especially when the user classifies it as "Safe"). I have tried varying the ILClassificationAction, but it seems the system ignores the action in favor of "cleaning up" the thread. Example of my current implementation: override func classificationResponse(for request: ILClassificationRequest) -> ILClassificationResponse { // Even when returning .none or .reportNotJunk let action: ILClassificationAction = (self.type == "spam") ? .reportJunk : .none let response = ILClassificationResponse(action: action) response.userInfo = ["type": self.taggedType, "sender": self.sender] return response } My Questions: Is there a specific ILClassificationAction or userInfo key that tells iOS not to move the message? Is this movement a mandatory "post-report cleanup" behavior of the IdentityLookup framework that cannot be overridden? Does anyone know a workaround to report the communication while maintaining its original location in the Messages app?

My macOS app is unable to read a Managed Preferences plist unless the App Sandbox is disabled. Is there any solution to read the MDM plist file while the sandbox is still enabled?
I created two sample apps — one sandboxed and one non‑sandboxed. I tested reading Managed Preferences using bash commands, CFPreferencesCopyValue for a domain, and defaults read. Everything works correctly only when the sandbox is disabled in the entitlements. When the sandbox is enabled, I’m unable to read values from /Library/Managed Preferences/. Is there any supported way for a sandboxed macOS app to read an MDM-delivered preference plist under /Library/Managed Preferences/? Any guidance on the correct and Apple‑supported method would be appreciated.

Can a third-party DriverKit HID dext seize raw HID reports from an external mouse via a top case–related path?
We are trying to determine whether a third-party DriverKit HID dext can seize or intercept raw HID input reports from an external mouse through any top case–related path in the HID stack. Our dext is based on IOUserHIDEventDriver, and the goal is to receive raw input reports before they are translated into higher-level pointer events. Apple’s public HIDDriverKit documentation describes IOUserHIDEventDriver as the driver object responsible for dispatching pointer, digitizer, scrolling, and related HID-originated events, but it is not clear to us whether any “top case” path is actually exposed or supported for third-party matching in DriverKit. What we want to clarify is specifically about external mouse devices, not the built-in trackpad itself. Questions: Is there any officially supported way for a third-party DriverKit HID dext to bind through a top case–related path and receive raw HID input reports from an external mouse? Is “top case” something that third-party DriverKit drivers can meaningfully target for matching/attachment, or is it only an internal Apple implementation detail? If such a path exists, can it be used to seize raw reports before they are converted into higher-level pointer events? If not, what is the officially supported boundary for third-party DriverKit access to raw reports from external mouse-class HID devices? To be clear, we are not asking about synthesizing pointer events. We are asking whether a third-party DriverKit dext can directly observe or seize the original HID input reports from an external mouse by attaching through any top case–related portion of the HID stack. If “top case” is not a public DriverKit concept that third parties can target, confirmation of that would also be very helpful.

Significant Location Change Event in two apps running on same device
I am using Significant Location Change (SLC) monitoring to relaunch my app after it has been terminated. I have implemented SLC in two separate apps installed on the same device, and I would like to understand how the system delivers SLC events in this scenario. Specifically: Will both apps receive the SLC event at the same time, or can there be differences in the timing of delivery? If there are differences, what factors influence when each app receives the event? What criteria or system conditions determine how and when SLC events are delivered to different apps on the same device? Any clarification on the event delivery behavior would be greatly appreciated.

Product ID conflict for IAP across staging/production apps
I’m working on a Flutter application that implements subscriptions using in-app purchases (IAP). I currently have two apps under the same developer account: One for staging One for production In App A (staging), I successfully created a monthly subscription with the product ID: rc_1299_monthly However, when I try to create a subscription with the same product ID (rc_1299_monthly) in App B (production), I encounter the following error: "The Product ID you entered is already being used by another subscription." My understanding was that product IDs are scoped per app, but this error suggests there may be account-level constraints. Has anyone encountered this before? Is it required to use unique product IDs across all apps under the same account, or is there a recommended approach for handling staging vs production setups? Any clarification or best practices would be appreciated.

SwiftData ModelContext Pollution with Multiple ModelContainers and Schemas
I have two different VersionedSchema accessed via two different and distinct in-memory ModelContainers. However, both schemas have a model named Item. LocalSchema.Item and RemoteSchema.Item have slightly different properties. If I create and save RemoteSchema.Item in one context then I cannot create and save LocalSchema.Item in a different context due to missing origin property. enum LocalSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { @Attribute(.unique) var title: String var created: Date var modified: Date init(title: String, created: Date, modified: Date) { self.title = title self.created = created self.modified = modified } } } enum RemoteSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { var title: String var created: Date var modified: Date var origin: String init(title: String, created: Date, modified: Date, origin: String) { self.title = title self.created = created self.modified = modified self.origin = origin } } } In the above example, saving RemoteSchema.Item will cause LocalSchema.Item to fail. The error message I see is *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSManagedObject 0xa120f3750> setValue:forUndefinedKey:]: the entity Item is not key value coding-compliant for the key "origin".' Test Code @Test func createLocalItemWithManualSave() async throws { let context = ModelContext(try localStore()) let item = LocalSchema.Item(title: "local", created: .now, modified: .now) context.insert(item) try context.save() } @Test func createRemoteItemWithManualSave() async throws { let context = ModelContext(try remoteStore()) let item = RemoteSchema.Item(title: "remote", created: .now, modified: .now, origin: "from space") context.insert(item) try context.save() } func localStore() throws -> ModelContainer { let schema = Schema(versionedSchema: LocalSchema.self) let config = ModelConfiguration("local", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } func remoteStore() throws -> ModelContainer { let schema = Schema(versionedSchema: RemoteSchema.self) let config = ModelConfiguration("remote", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } I have created FB22310365

Matter OTA on TestNet: HomePod always replies "UpdateNotAvailable" (Device is already CSA Certified)
Hi Apple Team / Community, We are currently pulling our hair out over a TestNet OTA issue and could really use some help. Our Matter Door Lock (VID: 5424, PID: 513) has already obtained official CSA Certification, so we are 100% confident that our device firmware and OTA Requestor logic are completely solid. However, we simply cannot get Apple's TestNet to serve the update via HomePod. Here is exactly what is happening: Our device successfully sends a QueryImage command to the HomePod. The HomePod receives it, but immediately fires back a QueryImageResponse that essentially means "UpdateNotAvailable", forcing the device into an 86400-second sleep timeout. Here is what we have verified so far: Local OTA works perfectly: If we use Nordic's chip-ota-provider-app locally with the exact same .ota file, the BDX transfer triggers instantly and the device updates without a hitch. DCL details are 100% accurate: We published a brand new version (1.0.4 / 16778240) which is strictly higher than the device's current version (1.0.1 / 16777472). The otaFileSize (973839) and Base64 Checksum match the file perfectly. ZERO hits on our server: The OTA file is hosted on an AWS S3 direct link (SSL Grade A via SSL Labs, ATS compliant). We checked our server logs, and there hasn't been a single download attempt from any Apple IP addresses. Since our device is certified and local OTA works flawlessly, it strongly feels like Apple's TestNet backend either has a stuck/cached "invalid" state for our VID/PID (very similar to what was reported in CHIP GitHub Issue #29338), or the Apple backend crawler is failing to reach our URL for some internal reason. Could someone please check if there is a cached exception for VID: 5424 / PID: 513 on the TestNet backend? Any help or pointers would be hugely appreciated! Thanks in advance.

Help with getting info for an WIFI USER EXPERIENCE APP
Hi I’m working on an app Called Wiux ( already on Android ) but one of my clients has a company with all iPhones so I need to develop the app for iOS, but I’m facing A huge wall, it’s an proactive wifi user experience monitor for distributed networks and the idea is that the app its sending every minute info about connectivity RSSI, which network , if is 2,4ghz or 5ghz channel used and device usage cpu ram etc but I find that is no getRSSI ( and I really need that data ) but some aps like iWifi or WiFi probe has that data and it works I check the reads with a phisical probe and my app on android and values match. i think maybe with NEHotspotHelper I could get the data but I don’t know how to ask to use it or if exist a dependency for quality monitoring that allows me to access that thow o info. ( And probably in the near future I face the same problem with LTE ( that I’m also monitoring with the app on Android and I think is going to be a problem on iOS )

How to create ControlWidget button that opens my App
Hi, I want to create a ControlWidget button that acts as a shortcut in the control center open a specific view within my app to show a badge. Problem: I can‘t get it to open my host app. I tried a custom myapp:// protocol - did not work, I tied AppIntent with the openAppWhenRun set to true - did not work and the strange thing is the debugger breakpoint in perform will only get triggered if this is set to false. OpenIntent did not work either even if I use a dummy swift app as host to try it out. What is the current supported way (iOS 18 and 26) to open your app when a static ControlWidget button is clicked, what could I have done wrong / am missing?

Screen Time APIs showing severe inconsistencies (DeviceActivity not firing + impossible usage data)
Hi everyone, I’m the developer of one sec, an app used by a large number of users globally to reduce time spent on social media and to build healthier digital habits. Because of this, we rely heavily on Apple’s Screen Time / DeviceActivity / FamilyControls, ManagedSettings APIs – and unfortunately, we’re seeing increasingly severe issues in production that directly impact hundreds of thousands of real iOS users. During the past years, we have been busy filing dozens of feedback requests for different Screen Time issues – and there has been no response from Apple at all. Developer Relations might be able to "confirm" that the bugs are present and that they ended up with the right team – but they are never addressed, neither are workarounds provided. Instead, the situation gets worse and worse. iOS 26 introduced a series of heavy regressions (which have been reported via Apple’s official bug report tool "Feedback Assistant" on iOS 26 beta 1 in June 2025 – and have not been addressed 10 Months later). This is very frustrating for us as developers, but also for our end-users who run into these issues every day. In the end this impacts our ability to build an amazing product and hurts revenue (which affects both us and Apple). 1. DeviceActivity thresholds are not firing at all This affects both: our app’s usage of the API and Apple’s own Screen Time limits Radars: FB22304617, FB20526837, FB15491936, FB12195437, FB15663329, FB18198691, FB18289475, FB19827144 2. Screen Time usage data is clearly corrupted Websites showing hundreds of hours per week Up to ~20 hours per day of usage reported for a single domain Radars: FB22304617, FB17777429, FB18464235 3. DeviceActivity thresholds reaching threshold immediately Newly introduced with iOS 26 Reported on iOS 26 beta 1 in June No response so far / no workaround DeviceActivity calls didReachThreshold immediately after creating the DeviceActivityEvent – instead of waiting till the defined threshold is actually reached. Radars: FB13696022, FB18351583, FB21320644, FB18927456, FB18061981 4. Randomly Randomizing ApplicationTokens From time to time, and without consistency, Screen Time suddenly provides new, random, unknown tokens to my app in the ShieldConfigurationDataSource and ShieldActionDelegate. This has been reported on many times before here on the dev forms, many many years back already: https://forums.developer.apple.com/forums/thread/756440 https://forums.developer.apple.com/forums/thread/758325 https://forums.developer.apple.com/forums/thread/758325?answerId=793267022#793267022 Radars: FB14082790 and FB18764644 5. Moving Tokens from one ManagedSettingsStore to Another Removing an ApplicationToken from one SettingsStore and then adding it to another while the target app remains in foreground leads to the re-use of the ShieldConfiguration. Which can be wrong in many scenarios. It is not possible to request a re-request of the ShieldConfiguration in that scenario. Radar: FB14237883 6. Unable to Open Parent App (one sec) from Shield Many times, when a target app is blocked by a shield, the user wants to perform some action (e.g. to unlock more time for the target app via an intervention). That means, that somehow I have to forward the user from a ShieldActionDelegate back into my target app. Unfortunately, there’s no API for that. Many apps on the App Store rely on private API to achieve that, but that’s too risky for a popular app like one sec. Radar: FB15079668 7. Unable to Open Target App from an ApplicationToken When a user has completed an intervention within one sec, and they indend to to continue to the target app, there is no way that one sec can open the target app just from the token alone. Sure, there are URL schemes, but that means the user has to manually assign URL schemes to each ApplicationToken. That is not a very user friendly process (and in many cases impossible, because not every app registers URL schemes). It would be better if there was a way that my app could open a target app directly from an ApplicationToken, e.g. via an AppIntent that can be run on a button press. This way, the selected apps would remain fully private while still offering advanced functionality: struct OpenTargetAppIntent: AppIntent, OpenAppFromApplicationTokenIntent { func perform() { return .result(openAppFromApplicationToken: applicationToken) } } Radar: FB15500695 Summary Thanks a lot for taking the time to read my feedback. If you have any questions, please feel free to reach out to me any time. I’m always happy to provide more details, logs, and steps to reproduce in my radars / feedback requests or in-person in Cupertino. It would be extremely helpful if someone from the Screen Time / DeviceActivity engineering team could: Take a look at the listed radars. Work on bug fixes and be transparent about when fixes will be shipped. Provide workarounds in the meantime. We genuinely want to build great, reliable experiences on top of Screen Time – but in its current state, it’s becoming very difficult to depend on. – Frederik

Maps: opening hours API / Property
I’m currently developing an iOS app that relies heavily on location details. I'm using MapKit and MKMapItem as my primary data source, which works perfectly for standard metadata. However, I’ve hit a roadblock: I want to display opening hours inline within my location details, but it seems Apple doesn't expose a public API or property for this in MKMapItem (even though the data is clearly visible in the native Apple Maps app). Since I'm building this as an indie developer/startup, the Google Places API is unfortunately too expensive for my current budget. ⁠Is there any legitimate, native way to get opening hours from Apple that I might have missed? ⁠If not, what are your best practices or recommended indie-friendly alternatives (e.g., Yelp Fusion API, OpenStreetMap, Foursquare)? Any tips on how to handle this elegantly and cost-efficiently would be highly appreciated! Thanks in advance.

Why don't my os_log entries show up until the second time my driver loads?
I'm in the process of writing a DriverKit USBHostInterface driver, and while I'm finally starting to get there, I've run into a bit of a frustration with logging. Naturally I have a liberal amount of os_log calls that I'm using to troubleshoot my driver. However I've noticed that they don't show up until after the first time my driver has loaded. Meaning, for example, suppose I make a new build of my driver and it's bundled user-mode app, install the bundle to /Applications, run the installer, verify it took with systemextensionsctl list, fire up Console and start streaming log entries, then plug in my device. I can see the log entries that show that my driver is loaded, etc., then a bunch of kernel -> log entries, but none of my Start method log entries. If I unplug my device and plug it in again, my log entries show up as expected. Why is this and, more importantly, how can I fix it? I'd like to see those log entries the first time the driver loads, if I could.

Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems
This is a bit complicated to explain so bare with me. I am working on building an app that allows you to send real time video/camera captures from one Apple device to another. I am using a custom UDP protocol built on top of NWListener, NWBrowser, and NWConnection APIs. It works fine, but there are a few issues that seems to all be related to awdl: When transmitting via WiFi over the router (not using peer-to-peer), there are periodic interruptions when the wireless card on the device changes channels for awdl polling. This is resolved by changing the 5GHz WiFi channel on the router to channel 149 (or disabling AWDL altogether which is not really feasible). In order to work around number 1, I decided to build in an option to toggle/prefer peer-to-peer transmission in the app thinking that if everything goes over a peer-to-peer connection the jitter caused from the channel switching should go away. This also works, but with an important caveat. The default transmission is extremely choppy until you take an OS action that “elevates” the AWDL connection into “realtime” mode. I am using includePeerToPeer on the listener, browser, and connection as well as serviceClass interactiveVideo. For number 1, you can understand that asking users to change the channel on their router is not a great user experience, but the problem is the peer-to-peer connection workaround is also not great by default. For number 2, as an example of the behavior, I can send a stream from my Mac to my iPad over a peer-to-peer connection and it works but the video is very choppy until I move my cursor from my Mac to my iPad to trigger Universal Control. I captured the OS logs while doing this and can confirm that something happens to trigger “realtime” mode on the AWDL connection. After that, the streaming is totally smooth with zero latency.

I have already tried a lot of things, but is there any way to programmatically trigger “realtime” mode? For additional context, the goal here is to have extremely low latency that also works for gaming. The actual latency introduced in 1 is approximately 30-50ms around once a second… adding a buffer to the stream makes the video completely smooth, but the extra delay on the receiver end is not acceptable for this use case. Any help or ideas would be appreciated. I can’t easily share a reproduce case right now, and even if I could, getting multiple devices into the exact state along with the router configuration in order to reproduce is going to be pretty difficult anyway.

"Invalid Certificate Signing Request" error when generating MDM Push Certificate
Hello, I am currently developing an MDM solution, including both the sever-side(.NET) and the client app. I have recently been granted the "MDM CSR" signing permission in the Certificates, Identifier & Profiles of my developer account. I am following the official Apple documentation, "Setting up Push Notifications for your MDM Customers," to generate the required MDM Push Certificate. However, I keep encountering the "Invalid Certificate Signing Request" error when uploading the encoded .plist file to the Apple Push Certificates Portal(identity.apple.com/pushcert). The steps I have taken so far: Generated .csr file via Keychain Access Used the MDM SCR certificate to sign the request. Created a .plist file for th final upload containing : Customer CSR: Base64 encoded Signature : Signed using the SHA256withRSA algorithm and Base64 encoded. Certificate Chain : Including my MDM Vendor Signing Certificate, the Apple WWDR intermediate certificate, and the Apple Root CA. Issues/Questions: Is there a specific requirement for the order of the certificates in the chain? Are there common pitfalls regarding the .plist structure or the encoding of the signature that might cause the "Invalid CSR" error? Is there a tool or a specific validation step I can use to verify the integrity of the generated .plist before uploading? I have double-checked the encoding and the signing process, but the portal continues to reject the request. Any insights or guidance from community would be greatly appreciated. Thank you in advance for your help!

Fatal error on rollback after delete
I encountered an error when trying to rollback context after deleting some model with multiple one-to-many relationships when encountered a problem later in a deleting method and before saving the changes. Something like this: do { // Fetch model modelContext.delete(model) // Do some async work that potentially throws try modelContext.save() } catch { modelContext.rollback() } When relationship is empty - the parent has no children - I can safely delete and rollback with no issues. However, when there is even one child when I call even this code: modelContext.delete(someModel) modelContext.rollback() I'm getting a fatal error: SwiftData/ModelSnapshot.swift:46: Fatal error: Unexpected backing data for snapshot creation: SwiftData._FullFutureBackingData<ChildModel> I use ModelContext from within the ModelActor but using mainContext changes nothing. My ModelContainer is quite simple and problem occurs on both in-memory and persistent storage, with or without CloudKit database being enabled. I can isolate the issue in test environment, so the model that's being deleted (or any other) is not being accessed by any other part of the application. However, problem looks the same in the real app. I also changed the target version of iOS from 18.0 to 26.0, but to no avail. My models look kind of like this: @Model final class ParentModel { var name: String @Relationship(deleteRule: .cascade, inverse: \ChildModel.parent) var children: [ChildModel]? init(name: String) { self.name = name } } @Model final class ChildModel { var name: String @Relationship(deleteRule: .nullify) var parent: ParentModel? init(name: String) { self.name = name } } I tried many approaches that didn't help: Fetching all children (via fetch) just to "populate" the context Accessing all children on parent model (via let _ = parentModel.children?.count) Deleting all children reading models from parent: for child in parentModel.children ?? [] { modelContext.delete(child) } Deleting all children like this: let parentPersistentModelID = parentModel.persistentModelID modelContext.delete(model: ChildModel.self, where: #Predicate { $0.parent.persistentModelID == parentPersistentModelID }, includeSubclasses: true) Removing @Relationship(deleteRule: .nullify) from ChildModel relationship definition I found 2 solution for the problem: To manually fetch and delete all children prior to deleting parent: let parentPersistentModelID = parentModel.persistentModelID for child in try modelContext.fetch(FetchDescriptor<ChildModel>(predicate: #Predicate { $0.parent.persistentModelID == parentPersistentModelID })) { modelContext.delete(child) } modelContext.delete(parentModel) Trying to run my code in child context (let childContext = ModelContext(modelContext.container)) All that sounds to me like a problem deep inside Swift Data itself. The first solution I found, fetching potentially hundreds of child models just to delete them in case I might need to rollback changes on some error, sounds like awful waste of resources to me. The second one however seems to work fine has that drawback that I can't fully test my code. Right now I can wrap the context (literally creating class that holds ModelContext and calls its methods) and in tests for throwing methods force them to throw. By creating scratch ModelContext I loose that possibility. What might be the real issue here? Am I missing something?

Remove Unused Network Links
Apple MacOS Sequoia 15.4.1 Creates a ton of unused network interfaces and it's a nightmare trying to figure out what they all do, what theyr're linked to, etc. It appears that network links utun0, utun1, utun2, ... are never used or useful. ip link shows they are all status UNKNOWN. I don't use a VPN or anything like that, and the documentation on these interfaces does not exist. I'd like to permanently delete them and permanently prevent them from ever being created again -- how can I accomplish this task?

iOS 26.4: Receipt of previous transaction is returned
Hi, We are facing issue with purchases on iOS 26.4. The app store receipt received is from previous transaction leading to receipt validation failures. There are some purchase success observed for pending transactions but success rate for pending transactions is also very low. We are using Unity In-App Purchasing (IAP) 4.13.0. Let us know for any more details and any fix / workaround available. Thanks.

Unwanted Communication Reporting Extension deletes messages always
I am implementing an Unwanted Communication Reporting Extension (IdentityLookupUI) to allow users to report spam messages to our backend. The extension works perfectly in terms of data collection and network reporting (using ILClassificationExtensionNetworkReportDestination). However, I’ve encountered an issue with the message lifecycle: whenever the user taps "Done" and I return a response, the system automatically moves the reported message to the Recently Deleted folder. I want to report the data but keep the message in its current folder (especially when the user classifies it as "Safe"). I have tried varying the ILClassificationAction, but it seems the system ignores the action in favor of "cleaning up" the thread. Example of my current implementation: override func classificationResponse(for request: ILClassificationRequest) -> ILClassificationResponse { // Even when returning .none or .reportNotJunk let action: ILClassificationAction = (self.type == "spam") ? .reportJunk : .none let response = ILClassificationResponse(action: action) response.userInfo = ["type": self.taggedType, "sender": self.sender] return response } My Questions: Is there a specific ILClassificationAction or userInfo key that tells iOS not to move the message? Is this movement a mandatory "post-report cleanup" behavior of the IdentityLookup framework that cannot be overridden? Does anyone know a workaround to report the communication while maintaining its original location in the Messages app?

My macOS app is unable to read a Managed Preferences plist unless the App Sandbox is disabled. Is there any solution to read the MDM plist file while the sandbox is still enabled?
I created two sample apps — one sandboxed and one non‑sandboxed. I tested reading Managed Preferences using bash commands, CFPreferencesCopyValue for a domain, and defaults read. Everything works correctly only when the sandbox is disabled in the entitlements. When the sandbox is enabled, I’m unable to read values from /Library/Managed Preferences/. Is there any supported way for a sandboxed macOS app to read an MDM-delivered preference plist under /Library/Managed Preferences/? Any guidance on the correct and Apple‑supported method would be appreciated.

Can a third-party DriverKit HID dext seize raw HID reports from an external mouse via a top case–related path?
We are trying to determine whether a third-party DriverKit HID dext can seize or intercept raw HID input reports from an external mouse through any top case–related path in the HID stack. Our dext is based on IOUserHIDEventDriver, and the goal is to receive raw input reports before they are translated into higher-level pointer events. Apple’s public HIDDriverKit documentation describes IOUserHIDEventDriver as the driver object responsible for dispatching pointer, digitizer, scrolling, and related HID-originated events, but it is not clear to us whether any “top case” path is actually exposed or supported for third-party matching in DriverKit. What we want to clarify is specifically about external mouse devices, not the built-in trackpad itself. Questions: Is there any officially supported way for a third-party DriverKit HID dext to bind through a top case–related path and receive raw HID input reports from an external mouse? Is “top case” something that third-party DriverKit drivers can meaningfully target for matching/attachment, or is it only an internal Apple implementation detail? If such a path exists, can it be used to seize raw reports before they are converted into higher-level pointer events? If not, what is the officially supported boundary for third-party DriverKit access to raw reports from external mouse-class HID devices? To be clear, we are not asking about synthesizing pointer events. We are asking whether a third-party DriverKit dext can directly observe or seize the original HID input reports from an external mouse by attaching through any top case–related portion of the HID stack. If “top case” is not a public DriverKit concept that third parties can target, confirmation of that would also be very helpful.

Significant Location Change Event in two apps running on same device
I am using Significant Location Change (SLC) monitoring to relaunch my app after it has been terminated. I have implemented SLC in two separate apps installed on the same device, and I would like to understand how the system delivers SLC events in this scenario. Specifically: Will both apps receive the SLC event at the same time, or can there be differences in the timing of delivery? If there are differences, what factors influence when each app receives the event? What criteria or system conditions determine how and when SLC events are delivered to different apps on the same device? Any clarification on the event delivery behavior would be greatly appreciated.

Product ID conflict for IAP across staging/production apps
I’m working on a Flutter application that implements subscriptions using in-app purchases (IAP). I currently have two apps under the same developer account: One for staging One for production In App A (staging), I successfully created a monthly subscription with the product ID: rc_1299_monthly However, when I try to create a subscription with the same product ID (rc_1299_monthly) in App B (production), I encounter the following error: "The Product ID you entered is already being used by another subscription." My understanding was that product IDs are scoped per app, but this error suggests there may be account-level constraints. Has anyone encountered this before? Is it required to use unique product IDs across all apps under the same account, or is there a recommended approach for handling staging vs production setups? Any clarification or best practices would be appreciated.

SwiftData ModelContext Pollution with Multiple ModelContainers and Schemas
I have two different VersionedSchema accessed via two different and distinct in-memory ModelContainers. However, both schemas have a model named Item. LocalSchema.Item and RemoteSchema.Item have slightly different properties. If I create and save RemoteSchema.Item in one context then I cannot create and save LocalSchema.Item in a different context due to missing origin property. enum LocalSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { @Attribute(.unique) var title: String var created: Date var modified: Date init(title: String, created: Date, modified: Date) { self.title = title self.created = created self.modified = modified } } } enum RemoteSchema: VersionedSchema { static var versionIdentifier: Schema.Version = .init(1, 0, 0) static var models: [any PersistentModel.Type] = [ Item.self ] @Model class Item { var title: String var created: Date var modified: Date var origin: String init(title: String, created: Date, modified: Date, origin: String) { self.title = title self.created = created self.modified = modified self.origin = origin } } } In the above example, saving RemoteSchema.Item will cause LocalSchema.Item to fail. The error message I see is *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSManagedObject 0xa120f3750> setValue:forUndefinedKey:]: the entity Item is not key value coding-compliant for the key "origin".' Test Code @Test func createLocalItemWithManualSave() async throws { let context = ModelContext(try localStore()) let item = LocalSchema.Item(title: "local", created: .now, modified: .now) context.insert(item) try context.save() } @Test func createRemoteItemWithManualSave() async throws { let context = ModelContext(try remoteStore()) let item = RemoteSchema.Item(title: "remote", created: .now, modified: .now, origin: "from space") context.insert(item) try context.save() } func localStore() throws -> ModelContainer { let schema = Schema(versionedSchema: LocalSchema.self) let config = ModelConfiguration("local", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } func remoteStore() throws -> ModelContainer { let schema = Schema(versionedSchema: RemoteSchema.self) let config = ModelConfiguration("remote", schema: schema, isStoredInMemoryOnly: true, allowsSave: true, cloudKitDatabase: .none) return try ModelContainer(for: schema, configurations: config) } I have created FB22310365

Matter OTA on TestNet: HomePod always replies "UpdateNotAvailable" (Device is already CSA Certified)
Hi Apple Team / Community, We are currently pulling our hair out over a TestNet OTA issue and could really use some help. Our Matter Door Lock (VID: 5424, PID: 513) has already obtained official CSA Certification, so we are 100% confident that our device firmware and OTA Requestor logic are completely solid. However, we simply cannot get Apple's TestNet to serve the update via HomePod. Here is exactly what is happening: Our device successfully sends a QueryImage command to the HomePod. The HomePod receives it, but immediately fires back a QueryImageResponse that essentially means "UpdateNotAvailable", forcing the device into an 86400-second sleep timeout. Here is what we have verified so far: Local OTA works perfectly: If we use Nordic's chip-ota-provider-app locally with the exact same .ota file, the BDX transfer triggers instantly and the device updates without a hitch. DCL details are 100% accurate: We published a brand new version (1.0.4 / 16778240) which is strictly higher than the device's current version (1.0.1 / 16777472). The otaFileSize (973839) and Base64 Checksum match the file perfectly. ZERO hits on our server: The OTA file is hosted on an AWS S3 direct link (SSL Grade A via SSL Labs, ATS compliant). We checked our server logs, and there hasn't been a single download attempt from any Apple IP addresses. Since our device is certified and local OTA works flawlessly, it strongly feels like Apple's TestNet backend either has a stuck/cached "invalid" state for our VID/PID (very similar to what was reported in CHIP GitHub Issue #29338), or the Apple backend crawler is failing to reach our URL for some internal reason. Could someone please check if there is a cached exception for VID: 5424 / PID: 513 on the TestNet backend? Any help or pointers would be hugely appreciated! Thanks in advance.

Help with getting info for an WIFI USER EXPERIENCE APP
Hi I’m working on an app Called Wiux ( already on Android ) but one of my clients has a company with all iPhones so I need to develop the app for iOS, but I’m facing A huge wall, it’s an proactive wifi user experience monitor for distributed networks and the idea is that the app its sending every minute info about connectivity RSSI, which network , if is 2,4ghz or 5ghz channel used and device usage cpu ram etc but I find that is no getRSSI ( and I really need that data ) but some aps like iWifi or WiFi probe has that data and it works I check the reads with a phisical probe and my app on android and values match. i think maybe with NEHotspotHelper I could get the data but I don’t know how to ask to use it or if exist a dependency for quality monitoring that allows me to access that thow o info. ( And probably in the near future I face the same problem with LTE ( that I’m also monitoring with the app on Android and I think is going to be a problem on iOS )

How to create ControlWidget button that opens my App
Hi, I want to create a ControlWidget button that acts as a shortcut in the control center open a specific view within my app to show a badge. Problem: I can‘t get it to open my host app. I tried a custom myapp:// protocol - did not work, I tied AppIntent with the openAppWhenRun set to true - did not work and the strange thing is the debugger breakpoint in perform will only get triggered if this is set to false. OpenIntent did not work either even if I use a dummy swift app as host to try it out. What is the current supported way (iOS 18 and 26) to open your app when a static ControlWidget button is clicked, what could I have done wrong / am missing?

Screen Time APIs showing severe inconsistencies (DeviceActivity not firing + impossible usage data)
Hi everyone, I’m the developer of one sec, an app used by a large number of users globally to reduce time spent on social media and to build healthier digital habits. Because of this, we rely heavily on Apple’s Screen Time / DeviceActivity / FamilyControls, ManagedSettings APIs – and unfortunately, we’re seeing increasingly severe issues in production that directly impact hundreds of thousands of real iOS users. During the past years, we have been busy filing dozens of feedback requests for different Screen Time issues – and there has been no response from Apple at all. Developer Relations might be able to "confirm" that the bugs are present and that they ended up with the right team – but they are never addressed, neither are workarounds provided. Instead, the situation gets worse and worse. iOS 26 introduced a series of heavy regressions (which have been reported via Apple’s official bug report tool "Feedback Assistant" on iOS 26 beta 1 in June 2025 – and have not been addressed 10 Months later). This is very frustrating for us as developers, but also for our end-users who run into these issues every day. In the end this impacts our ability to build an amazing product and hurts revenue (which affects both us and Apple). 1. DeviceActivity thresholds are not firing at all This affects both: our app’s usage of the API and Apple’s own Screen Time limits Radars: FB22304617, FB20526837, FB15491936, FB12195437, FB15663329, FB18198691, FB18289475, FB19827144 2. Screen Time usage data is clearly corrupted Websites showing hundreds of hours per week Up to ~20 hours per day of usage reported for a single domain Radars: FB22304617, FB17777429, FB18464235 3. DeviceActivity thresholds reaching threshold immediately Newly introduced with iOS 26 Reported on iOS 26 beta 1 in June No response so far / no workaround DeviceActivity calls didReachThreshold immediately after creating the DeviceActivityEvent – instead of waiting till the defined threshold is actually reached. Radars: FB13696022, FB18351583, FB21320644, FB18927456, FB18061981 4. Randomly Randomizing ApplicationTokens From time to time, and without consistency, Screen Time suddenly provides new, random, unknown tokens to my app in the ShieldConfigurationDataSource and ShieldActionDelegate. This has been reported on many times before here on the dev forms, many many years back already: https://forums.developer.apple.com/forums/thread/756440 https://forums.developer.apple.com/forums/thread/758325 https://forums.developer.apple.com/forums/thread/758325?answerId=793267022#793267022 Radars: FB14082790 and FB18764644 5. Moving Tokens from one ManagedSettingsStore to Another Removing an ApplicationToken from one SettingsStore and then adding it to another while the target app remains in foreground leads to the re-use of the ShieldConfiguration. Which can be wrong in many scenarios. It is not possible to request a re-request of the ShieldConfiguration in that scenario. Radar: FB14237883 6. Unable to Open Parent App (one sec) from Shield Many times, when a target app is blocked by a shield, the user wants to perform some action (e.g. to unlock more time for the target app via an intervention). That means, that somehow I have to forward the user from a ShieldActionDelegate back into my target app. Unfortunately, there’s no API for that. Many apps on the App Store rely on private API to achieve that, but that’s too risky for a popular app like one sec. Radar: FB15079668 7. Unable to Open Target App from an ApplicationToken When a user has completed an intervention within one sec, and they indend to to continue to the target app, there is no way that one sec can open the target app just from the token alone. Sure, there are URL schemes, but that means the user has to manually assign URL schemes to each ApplicationToken. That is not a very user friendly process (and in many cases impossible, because not every app registers URL schemes). It would be better if there was a way that my app could open a target app directly from an ApplicationToken, e.g. via an AppIntent that can be run on a button press. This way, the selected apps would remain fully private while still offering advanced functionality: struct OpenTargetAppIntent: AppIntent, OpenAppFromApplicationTokenIntent { func perform() { return .result(openAppFromApplicationToken: applicationToken) } } Radar: FB15500695 Summary Thanks a lot for taking the time to read my feedback. If you have any questions, please feel free to reach out to me any time. I’m always happy to provide more details, logs, and steps to reproduce in my radars / feedback requests or in-person in Cupertino. It would be extremely helpful if someone from the Screen Time / DeviceActivity engineering team could: Take a look at the listed radars. Work on bug fixes and be transparent about when fixes will be shipped. Provide workarounds in the meantime. We genuinely want to build great, reliable experiences on top of Screen Time – but in its current state, it’s becoming very difficult to depend on. – Frederik

Maps: opening hours API / Property
I’m currently developing an iOS app that relies heavily on location details. I'm using MapKit and MKMapItem as my primary data source, which works perfectly for standard metadata. However, I’ve hit a roadblock: I want to display opening hours inline within my location details, but it seems Apple doesn't expose a public API or property for this in MKMapItem (even though the data is clearly visible in the native Apple Maps app). Since I'm building this as an indie developer/startup, the Google Places API is unfortunately too expensive for my current budget. ⁠Is there any legitimate, native way to get opening hours from Apple that I might have missed? ⁠If not, what are your best practices or recommended indie-friendly alternatives (e.g., Yelp Fusion API, OpenStreetMap, Foursquare)? Any tips on how to handle this elegantly and cost-efficiently would be highly appreciated! Thanks in advance.

Why don't my os_log entries show up until the second time my driver loads?
I'm in the process of writing a DriverKit USBHostInterface driver, and while I'm finally starting to get there, I've run into a bit of a frustration with logging. Naturally I have a liberal amount of os_log calls that I'm using to troubleshoot my driver. However I've noticed that they don't show up until after the first time my driver has loaded. Meaning, for example, suppose I make a new build of my driver and it's bundled user-mode app, install the bundle to /Applications, run the installer, verify it took with systemextensionsctl list, fire up Console and start streaming log entries, then plug in my device. I can see the log entries that show that my driver is loaded, etc., then a bunch of kernel -> log entries, but none of my Start method log entries. If I unplug my device and plug it in again, my log entries show up as expected. Why is this and, more importantly, how can I fix it? I'd like to see those log entries the first time the driver loads, if I could.

Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems
This is a bit complicated to explain so bare with me. I am working on building an app that allows you to send real time video/camera captures from one Apple device to another. I am using a custom UDP protocol built on top of NWListener, NWBrowser, and NWConnection APIs. It works fine, but there are a few issues that seems to all be related to awdl: When transmitting via WiFi over the router (not using peer-to-peer), there are periodic interruptions when the wireless card on the device changes channels for awdl polling. This is resolved by changing the 5GHz WiFi channel on the router to channel 149 (or disabling AWDL altogether which is not really feasible). In order to work around number 1, I decided to build in an option to toggle/prefer peer-to-peer transmission in the app thinking that if everything goes over a peer-to-peer connection the jitter caused from the channel switching should go away. This also works, but with an important caveat. The default transmission is extremely choppy until you take an OS action that “elevates” the AWDL connection into “realtime” mode. I am using includePeerToPeer on the listener, browser, and connection as well as serviceClass interactiveVideo. For number 1, you can understand that asking users to change the channel on their router is not a great user experience, but the problem is the peer-to-peer connection workaround is also not great by default. For number 2, as an example of the behavior, I can send a stream from my Mac to my iPad over a peer-to-peer connection and it works but the video is very choppy until I move my cursor from my Mac to my iPad to trigger Universal Control. I captured the OS logs while doing this and can confirm that something happens to trigger “realtime” mode on the AWDL connection. After that, the streaming is totally smooth with zero latency.

I have already tried a lot of things, but is there any way to programmatically trigger “realtime” mode? For additional context, the goal here is to have extremely low latency that also works for gaming. The actual latency introduced in 1 is approximately 30-50ms around once a second… adding a buffer to the stream makes the video completely smooth, but the extra delay on the receiver end is not acceptable for this use case. Any help or ideas would be appreciated. I can’t easily share a reproduce case right now, and even if I could, getting multiple devices into the exact state along with the router configuration in order to reproduce is going to be pretty difficult anyway.
