I've been seeing a high number of BGTaskScheduler related crashes, all of them coming from iOS 18.4. I've encountered this myself once on launch upon installing my app, but haven't been able to reproduce it since, even after doing multiple relaunches and reinstalls. Crash report attached at the bottom of this post. I am not even able to symbolicate the reports despite having the archive on my MacBook: Does anyone know if this is an iOS 18.4 bug or am I doing something wrong when scheduling the task? Below is my code for scheduling the background task on the view that appears when my app launches: .onChange(of: scenePhase) { newPhase in if newPhase == .active { #if !os(macOS) let request = BGAppRefreshTaskRequest(identifier: "notifications") request.earliestBeginDate = Calendar.current.date(byAdding: .hour, value: 3, to: Date()) do { try BGTaskScheduler.shared.submit(request) Logger.notifications.log("Background task scheduled. Earliest begin date: \(request.earliestBeginDate?.description ?? "nil", privacy: .public)") } catch let error { // print("Scheduling Error \(error.localizedDescription)") Logger.notifications.error("Error scheduling background task: \(error.localizedDescription, privacy: .public)") } #endif ... } 2025-02-23_19-53-50.2294_+0000-876d2b8ec083447af883961da90398f00562f781.crash

I'm seeing a lot of these in my logs: PersistentIdentifier PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-swiftdata://Course/BC9CF99A-DE6A-46F1-A18D-8034255A56D8), implementation: SwiftData.PersistentIdentifierImplementation) was remapped to a temporary identifier during save: PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-coredata:///Course/t58C849CD-D895-4773-BF53-3F63CF48935B210), implementation: SwiftData.PersistentIdentifierImplementation). This is a fatal logic error in DefaultStore ... though everything seems to work. Does anyone know what this means in this context? Anything I can do to not have this appear?

Since upgrading to Xcode 26 beta 4 and using the iOS 26 simulator for testing our app, we've stopped being able to receive device tokens for the simulator from the development APNS environment. The APNS environment is able to return meta device information (e.g. model, type, manufacturer) but there are no device tokens present. When running the same app using the iOS 18.5 simulator, we are able to register the device with the same APNS environment and receive a valid device token.

When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

On iOS 18.x when try to create EASession we get nil, but on iOS 17.x everything works. We have app which use USB cable for connecting external accessories. Scenario is when we have fresh instal, connecting with accessory work fine, EASession is created, streams are opened. When we unplug USB, we close streams, remove any reference to session and accessory, remove accessory delegate. When plug it again, creating EASession is returning nil. Only after restarting iPhone, we can create new EASession with appropriate protocol and accessory. Every next attempt without reseting iPhone is failing. Logs from accessory is following: 00:05:51.811000 : onUSBDeviceFound(pDevice=0xffc818)) iPhone USB device already in the device list w/id=1 -> update status now[21;1H 00:05:51.830000 : setConnectionStatus(status=connected) [devId=1] state updated -> forward[21;1H Capabilities indicate HostMode possibility => role switch is triggered 00:05:52.848000 : updateDIPODeviceConnections() iPhoneUSB w/caps=5 (=CarPlay or HostMode), deviceTag=2 in Device mode -> request role switch[21;1H Role switch seems to be successful 00:05:54.914000 : setSwitching('stable') changed[21;1H 00:05:54.915000 : updateDIPODeviceConnections() iPhoneUSB w/caps=2, id=1, deviceTag=2 and native transport -> request app launch and call connectUSB[21;1H 00:05:54.967000 : ConnectiAP2(05ac:12a8, s/n='00008101000160921E90801E', writeFD='/dev/ffs/ep3', readFD='/dev/ffs/ep4', hostMode){3}[21;1H Native transport should become available but does not (the following line is not present for failed case.

Also what is strange is that it works on fresh instal/restart iPhone, but not working on second attempt?

I have an Apple app that uses SwiftData and icloud to sync the App's data across users' devices. Everything is working well. However, I am facing the following issue: SwiftData does not support public sharing of the object graph with other users via iCloud. How can I overcome this limitation without stopping using SwiftData? Thanks in advance!

Our app uses a 24-hour DeviceActivityMonitor repeating schedule to send users notifications for every hour of screen time they spend on their phone per day. Notifications are sent from eventDidReachThreshold callbacks at 1, 2, 3, etc, hour thresholds to keep them aware of their screen time. We have recently received an influx of emails from our users that after updating to iOS 17.6.1 their DeviceActivityMonitor notifications are saying their screen time was much higher than what is shown in DeviceActivityReport and their device's Screen Time settings. These users have disabled "Share Across Devices" - but I suspect the DeviceActivityMonitor is still getting screen time from their other devices even though that setting is turned off. Has anybody else noticed this, understands what is causing this, or could recommend a fix that we can tell our users to do?

Hello everyone, I used SwiftData for v1 of an app and am now trying to make changes to the schema for v2. I created the v2 schema that adds a property to one of the models. I need to populate the new property so I made a custom migration using didMigrate. However that doesn't seem to matter what I do in the migration because creating the ModelContainer throws an error before didMigrate ever gets called. The error is: Unresolved error loading container Error Domain=NSCocoaErrorDomain Code=134060 "A Core Data error occurred." UserInfo={NSLocalizedFailureReason=Instances of NSCloudKitMirroringDelegate are not reusable and should have a lifecycle tied to a given instance of NSPersistentStore.} Higher up in the Xcode output I see things like this (in order): Request 'D25A8CB8-7341-4FA8-B2F8-3DE2D35B5273' was cancelled because the store was removed from the coordinator. BUG IN CLIENT OF CLOUDKIT: Registering a handler for a CKScheduler activity identifier that has already been registered CloudKit setup failed because it couldn't register a handler for the export activity. There is another instance of this persistent store actively syncing with CloudKit in this process. How can I know from this output what I am doing incorrectly? Any idea what I should take a look at or try to do differently? This is a simple app with three models and nothing fancy. The only change in the schema is to add a property. The new property is declared as optional and has an inverse that is also declared as optional. Thanks for any insight!

In my app, I am using geofencing to perform an action when the user enter or leaves a specified location. The geofencing (CLMonitor) is active permanently, and should work across multiple app sessions or after the device is restarted. It should also work after the app was minimized or terminated. This worked perfectly with iOS 17 and prior, but with iOS 18, things changed. As soon as iOS 18 dropped, users were informing me that the app does no longer perform the entry/exit action reliably (without me making any changes to the app). Most of the times, events are missed entirely. Sometimes, after the user opens or resumes the app, duplicate events are delivered and/or events with the current time instead of the correct time of entry/exit. I am making sure that the app has the "Always" location permission before geofencing is enabled The gefocence radius is between 20 and 500m, but even with the max. radius specified, the geofencing is unreliable For the same user and geofence, the entry/exit event is delivered occasionally, but not always I am currently not using CLLocationManager.allowsBackgroundLocationUpdates (even though it's documented as "Apps that receive location updates when running in the background must include the UIBackgroundModes key (with the location value) in their app’s Info.plist file") because it wasn't necessary on iOS 17 and in my tests, using it didn't yield any improvements In my search for what could have caused this change, I found this WWDC video about location authorization: . It appears that with iOS 18, it is now required to have an active CLServiceSession to ensure that location updates are delivered to my app. Even though the video is long (and I've watched it multiple times), some things are still unclear. For example, the docs state: If your app actively receives and processes location updates and terminates, it should restart those APIs upon launch in order to continue receiving updates. Also, in the video it is stated that: ... So your job, ..., is to make sure that your process launch logic knows what features it has been tasked with pursuing, and re-takes session objects... But on the other hand it's also said that: you can only start holding one (a CLServiceSession) when your app is in the foreground and also ... CLMonitor.events won’t yield results when it is not in use, unless a session which was started in the foreground, .... To summarize my questions, for the geofencing to work as described above: when exactly do I need to create a CLServiceSession if the app is launched into the backgorund? Immediately in the applicationDidFinishLaunching method, even though the app is still in the background (applicationState is background)? Or later on, when the app is opened again by the user, e.g. in applicationDidBecomeActive (and applicationState is active)? do I need to specify the background mode capability as noted in the Handling location updates in the background article? do I need to create a CLBackgroundActivitySession as noted in the Handling location updates in the background article? does it matter, which of the four initializer methods I am using to create the CLServiceSession (with CLServiceSessionAuthorizationRequirementAlways)? does it matter if I specify NSLocationRequireExplicitServiceSession in the Info.plist or not when I already do ensure that the app has the "Always" location permission when the feature is being enabled Does a CLServiceSession last indefinitely and should it only be invalidated once the user disables the feature?

I am trying to localize the CFBundleDisplayName and OSBundleUsageDescription of a driver that is part of an app. I am able to use InfoPlist.strings files to localize the Bundle display name for the app, but when I try to use the same file as part of the driver, the name displayed in settings for the app does not change correctly. In fact, it seems to follow the default language set in the xcode project. If the default language is not included in the suite of InfoPlist.strings files, it seems to take the string from the info.plist file. sometimes it just seems to take the English version regardless of the default language or tablet language. Has anyone had success with this?

We have identified an issue on iOS 18 and iOS 18.1 (developer beta) where App Clips invoked via NFC or QR codes without a pre-configured Advanced App Clip experience (aka they should be using the Default App Clip Experience) are not functioning as expected. This issue is specific to iOS 18, as the behavior works correctly on iOS devices running 17.x. Steps to Reproduce: Set up two scenarios: One scenario where an App Clip has a pre-configured advanced app clip experience (with metadata such as title, subtitle, image). Another scenario where the App Clip is invoked without any pre-configured experience (should use the default App Clip experience). On an iOS 18 or iOS 18.1 device: For the default App Clip experience (no pre-configured advanced app clip experence): Scan the NFC tag when the phone is locked. Scan the NFC tag when the phone is unlocked. Scan the QR code. For the pre-configured App Clip experience: Perform the same tests (NFC and QR code scans). Test the same scenarios on an iOS 17 device for comparison. Expected Behavior: For default App Clip experience invocations (NFC or QR): Scanning NFC or QR should still trigger the App Clip card, even without metadata or a pre-configured advanced experience, on both locked and unlocked devices. For pre-configured Advanced App Clip Experence invocations: The App Clip card should display correctly with the configured metadata and behave as expected on both locked and unlocked devices. Observed Behavior on iOS 18 and iOS 18.1: For default App Clip experience invocations: When scanning the NFC tag on a locked device, an error message is shown - e.g., "App Clip Unavailable" or "The operation couldn't be completed. (CPSErrorDomain error 2.)" . When scanning the NFC tag on an unlocked device, the system redirects straight to the web browser instead of displaying the App Clip card (or even the normal NFC top of screen push notification style thing) Scanning the QR code also prompts the user to open the web browser similar to the experience of scanning a non app clip QR code, skipping the expected App Clip experience. For pre-configured Advanced App Clip Experence invocations: The App Clip behaves as expected, showing the correct card with metadata and functioning properly on both locked and unlocked devices. Notes: The issue is only observed on iOS 18 and iOS 18.1, while the expected behavior is working fine on iOS 17. This may indicate a regression or change in behavior introduced with iOS 18 that affects App Clip invocations that do not have a pre-configured experience.

Hi, It seems that on M4 devices any virtual machine with macOS version older than 13.4 fail to boot, they stuck with a black screen. This is regardless of the virtualization software used (UTM, VirtualBuddy, Viable, etc...). After talking to many people everyone experiences the same. At least for me, this is a massive limitation of the platform, I really hope this is a bug which can be fixed. Thanks, Csaba

Hello! I'm developing NETransparentProxyProvider which started to work unexpectedly on macOS 15. Seems that iCloud Private Relay is not auto-disabled anymore in favor of another filtering software, when Firewall is enabled in macOS 15. Disabling firewall immediately restores old behavior. To reproduce this issue, you need to enable both iCloud Private Relay and Firewall. Then, Safari will always try to use iCloud Private Relay, even if Transparent Proxy has "destinationAddress:nil" rule. Every connection from Safari will be to "mask.icloud.com" over HTTP/3. Connections inside are not visible as separate flows. Since I have excludedRule for "icloud.com" (to not to alter Apple services), Safari traffic is just stopped to be processed. Is new behavior is expected or some type of regression?

Could someone please explain how to use a custom sound when setting up an alarm using AlarmKit? It keeps playing a default sound. Also, I keep having an issue where the alarm sound plays but doesn’t show the alarm interface buttons unless the screen is locked.

有一个用户反馈7月8日充值了3笔后一直无法发起新的购买，总是提示已经购买。我们查了是之前的交易无法结束，我们使用StoreKit2，已经调用await transaction.finish()成功结束交易了，但是每次发起新支付时，Transaction.unfinished还会返回之前已完成的交易信息。 是设备或AppleID的问题么？用户尝试了重启设备、重新登录AppleID都没用。有什么办法解决呢？ 用户无法结束的苹果交易id为：200002703899379、200002703900716、200002703902023。 A user reported that after making 3 purchases on July 8th, they have been unable to initiate new purchases, always receiving a prompt that the item has already been purchased. Upon investigation, we found that the previous transactions couldn't be finalized. We use StoreKit2 and have successfully called await transaction.finish() to end the transactions. However, every time a new payment is initiated, Transaction.unfinished still returns information about the previously completed transactions. Could this be an issue with the device or Apple ID? The user has tried restarting the device and re-logging into their Apple ID, but these attempts were unsuccessful. Is there any way to resolve this? The Apple transaction IDs that the user is unable to finalize are: 200002703899379, 200002703900716, 200002703902023.

Hello, We have a Push-to-Talk (PTT) application that is already well established and widely used. Our app has the proper VoIP entitlement, which we are using to wake up the app and establish a WebSocket connection for real-time communication. We are also using CallKit as a supporting mechanism, but not as the primary interaction upon receiving the VoIP Push, since our use case differs from traditional full-duplex VoIP calls. While our implementation works correctly in many cases, we have noticed a consistent issue where, after multiple VoIP Push notifications, the system still delivers the push, but prevents the WebSocket from reconnecting. At this point, all connection attempts return errors such as: • "Software caused connection abort" This issue persists until the app is manually relaunched, after which the behavior resets and repeats. We are aware that VoIP Push was originally designed for full-duplex calls, but since Apple allows its use for other purposes through the entitlement, we would like to understand why this limitation is occurring and how to handle it properly. Questions: 1. Is iOS enforcing stricter background execution rules after multiple VoIP Push events within a short period? 2. Are there any recommended best practices to ensure reliable WebSocket reconnection in this scenario?

Prior to iOS 14 our Dev server was routing universal links to our test devices just fine from both Xcode and TestFlight builds. But now that we've started testing on iOS 14 devices the links aren't being handled any more. After doing some research we noticed the new configuration regarding Associated Domains for web servers that aren't reachable from the public internet. https://developer.apple.com/documentation/safariservices/supporting_associated_domains Starting with macOS 11 and iOS 14, apps no longer send requests for apple-app-site-association files directly to your web server. Instead, they send these requests to an Apple-managed content delivery network (CDN) dedicated to associated domains. While you’re developing your app, if your web server is unreachable from the public internet, you can use the alternate mode feature to bypass the CDN and connect directly to your private domain.You enable an alternate mode by adding a query string to your associated domain’s entitlement as follows: <service>:<fully qualified domain>?mode=<alternate mode> Given our Dev server is only reachable via a VPN we changed our project config to use the alternate mode: <key>com.apple.developer.associated-domains</key> <array> <string>webcredentials:ourDevServerURL?mode=developer</string> <string>applinks:ourDevServerURL?mode=developer</string> </array> But unfortunately that still doesn't work and in the console we can see the following swcd logs being generated after a fresh app install. debug com.apple.swc 11:45:19.016561-0600 swcd entry Skipping domain si….va….com?mode=developer because developer mode is disabled So what else do we need to get developer mode working for these app links?

I've recently published an app, and while developing it, I could always get consistent entitlements from Transaction.currentEntitlements. But now I see some inconsistent behaviour for a subscribed device in the AppStore version. It looks like sometimes the entitlements do not emit value for the subscriptions. It usually happens on the first couple tries when the device goes offline, or on the first couple tries when the device goes online. But it also happens randomly at other times as well. Can there be a problem with Transaction.currentEntitlements when the connectivity was just changed? Of course my implementation may also be broken. I will give you the details of my implementation below. I have a SubscriptionManager that is observable (irrelevant parts of the entity is omitted): final class SubscriptionManager: NSObject, ObservableObject { private let productIds = ["yearly", "monthly"] private(set) var purchasedProductIDs = Set<String>() var hasUnlockedPro: Bool { return !self.purchasedProductIDs.isEmpty } @MainActor func updatePurchasedProducts() async { var purchasedProductIDs = Set<String>() for await result in Transaction.currentEntitlements { guard case .verified(let transaction) = result else { continue } if transaction.revocationDate == nil { purchasedProductIDs.insert(transaction.productID) } else { purchasedProductIDs.remove(transaction.productID) } } // only update if changed to avoid unnecessary published triggers if purchasedProductIDs != self.purchasedProductIDs { self.purchasedProductIDs = purchasedProductIDs } } } And I call the updatePurchasedProducts() when the app first launches in AppDelegate, before returning true on didFinishLaunchingWithOptions as: Task(priority: .high) { await DependencyContainer.shared.subscriptionManager.updatePurchasedProducts() } You may be wondering maybe the request is not finished yet and I fail to refresh my UI, but it is not the case. Because later on, every time I do something related to a subscribed content, I check the hasUnlockedPro computed property of the subscription manager, which still returns false, meaning the purchasedProductIDs is empty. You may also be curious about the dependency container approach, but I ensured by testing multiple times that there is only one instance of the SubscriptionManager at all times in the app. Which makes me think maybe there is something wrong with Transaction.currentEntitlements I would appreciate any help regarding this problem, or would like to know if anyone else experienced similar problems.

Hi, my app makes tcp connection successfully on macOS 15. But, after restarting Mac, the app fails to make tcp connection. The app is allowed in Settings > Privacy & Security > Local Network. If I deny it and then allow it again, the app can make tcp connection successfully. Is it a macOS Sequoia bug?

My App payment encountered a unkonw((StoreKit.StoreKitError) error = unknown) error in iOS18.2, then the lldb log "Could not find a visible window in the scene for *** purchase."."***" is purchase product id. Why does this error occur, and how can I fix it?
