Notification content extension not working
Are there some requirements to use Notification Content Extensions other than including the target to my iOS app? I have done it, configured it to match a certain category of notifications, but my custom interface doesn’t show up. is there anything I need to configure on my main app? Is that anything that should be changed there, such as disabking its botifications handling? is there any requirement concerning the payload? I tried to disable time sensitive and content-available notifications, but it didn’t help.

Potentially Unfair Limitation for Third-Party Keyboard Developers
When developing a custom keyboard on iOS, even after enabling Full Access (RequestsOpenAccess = true), it is still not possible to record audio — the recording simply does not start. This is despite the fact that: the user is explicitly warned the user provides informed consent by enabling Full Access According to Apple’s documentation: https://developer.apple.com/documentation/uikit/configuring-open-access-for-a-custom-keyboard “However, with RequestsOpenAccess set to true, the keyboard has all the capabilities in the preceding list.” At the same time, the preceding list includes: “No access to microphone and speaker” This creates ambiguity. The wording suggests that enabling Full Access should lift prior restrictions, yet in practice, microphone access remains unavailable to third-party keyboards. Why this is concerning With Full Access enabled, a keyboard already has: network access the ability to transmit user input From a privacy standpoint, this is already highly sensitive. Preventing microphone access while allowing these capabilities appears inconsistent. Meanwhile, Apple’s own system keyboard supports voice dictation, which creates a functional gap between first-party and third-party keyboards. Competition perspective This raises a broader question about equal access to platform capabilities. Restricting third-party keyboards from using the microphone — while first-party solutions can — may be seen as: unequal treatment of developers a limitation of competition in input methods Such differences are increasingly scrutinized under EU regulations like the Digital Markets Act and Article 102 TFEU, which emphasize fair access to platform features and prohibit self-preferencing by dominant platforms. Request for clarification Is microphone access intentionally restricted for all third-party keyboards, even with Full Access enabled? If so, what is the technical or policy justification? Are there plans to provide a secure and user-consented way to enable audio input for custom keyboards? Clarification on this would help developers better understand platform limitations and design decisions.

Urgent: Bundle ID Case-Sensitivity Mismatch for Approved Family Controls Entitlement
Hello, I have a critical issue regarding the "Family Controls (Distribution)" entitlement. My app "FocusPact" was approved for the entitlement, but there is a technical mismatch in the Bundle IDs that prevents distribution via TestFlight. [Current Situation] Parent App ID: com.hayashikento.FocusPact (Approved / Capitalized) Approved Extension ID: com.hayashikento.focuspact.ShieldConfigurationExtension (Approved / Lowercase) [The Issue] Due to the case-sensitivity difference (FocusPact vs focuspact), Xcode throws a "Bundle identifier prefix mismatch" error. Since the parent app identifier is already established as capitalized, I cannot change it to lowercase without breaking the existing configuration. [Request] I have submitted a new entitlement request with the corrected capitalized Bundle ID: Corrected Extension ID: com.hayashikento.FocusPact.ShieldConfigurationExtension Could a DTS engineer please help me synchronize the approved status to this capitalized ID? This is purely a technical correction of an already authorized functionality. Team ID: UHG4J7F7NH App Apple ID: 67591326449 Thank you for your assistance. I am a student developer eager to start MVP testing as soon as this is resolved.

URL Filter Prefetch Interval guarantee
Hello, I have implemented a URL Filter using the sample provided here: Filtering Traffic by URL. I am also using an App Group to dynamically manage the Bloom filter and block list data. However, when I update my block list URLs and create a new Bloom filter plist in the App Group, the extension does not seem to use the updated Bloom filter even after the prefetch interval expires. Also for testing purpose can I keep this interval to 10 mins or below ?

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?

I would like to request clarification regarding the behavior of the Live Activity Start Token used in the Xcode and iOS development workflow.
Could you please provide guidance on the following points: Start Token Throttling Are there any throttling limits or rate restrictions applied to Start Tokens? Token Invalidation Scenarios Under what specific conditions can a Start Token become invalidated? Are there known scenarios that trigger invalidation? Token Regeneration Timeline Once a Start Token is invalidated, how long does it typically take before a new token can be successfully generated and validated? Frequency of Invalidation Is there any documented or expected frequency with which Start Tokens may become invalid, assuming a normal development workflow? Impact on Push Notification Token When a live activity Start Token becomes invalid, does this also cause APNs Push Notification Tokens to be invalidated or refreshed automatically?

Implementing PHBackgroundResourceUploadExtension
Hi, I am trying to implement a PHBackgroundResourceUploadExtension to upload backup media files to an external cloud service based on these docs: https://developer.apple.com/documentation/PhotoKit/uploading-asset-resources-in-the-background#Acknowledge-completed-jobs Creating jobs and actual uploading is working as expected, but the problem I have is in the acknowledgeCompletedJobs() function. When trying to access a job's resource, the resource is nil and thus has empty assetLocalIdentifier and originalFilename. Did anybody successfully implement this extension or knows, why this would happen? Because the resource of an acknowledgable job is empty, I can not match it back to my processed assets.

After using the fskit framework to mount thecloud disk, it does not display on the Finder sidebar
I developed a cloud drive using fskit, but after mounting it, it did not appear in the Finder sidebar and the disk tool could not list it. How should I adapt? The mounting looks successful, and you can also open and see the fixed files I wrote in the code. I have also turned on the Finder sidebar settings function

Is it possible for an iOS app extension to support App Attest?
From watching the video on App Attest the answer would appear to be no, but the video is a few years old so in hope, I thought I would post this question anyway. There's several scenarios where I would like a notification service extension to be able to use App Attest in communications with the back end(for example to send a receipt to the backend acknowledging receipt of the push, fetching an image from a url in the push payload, a few others). Any change App Attest can be used in by a notification service extension?

How does AccessoryNotifications forward notifications to BLE accessories? What Service/Characteristic should the accessory implement?
Environment: iOS 26.4 beta Xcode 26.4 beta Framework: AccessoryNotifications, AccessorySetupKit, AccessoryTransportExtension Description: I'm implementing notification forwarding to a custom BLE accessory using the new AccessoryNotifications framework in iOS 26.4. I've set up an AccessoryDataProvider extension following the documentation, but I'm unclear about how the data is actually transmitted to the BLE accessory. Current Implementation: Main App - Uses AccessorySetupKit to discover and pair accessories: let descriptor = ASDiscoveryDescriptor() descriptor.bluetoothServiceUUID = CBUUID(string: "FEE0") let displayItem = ASPickerDisplayItem( name: "Notification Accessory", productImage: UIImage(systemName: "applewatch")!, descriptor: descriptor ) accessorySession.showPicker(for: [displayItem]) { error in // Handle error } AccessoryDataProvider Extension - Implements NotificationsForwarding.AccessoryNotificationsHandler: @main struct AccessoryDataProvider: AccessoryTransportExtension.AccessoryDataProvider { @AppExtensionPoint.Bind static var boundExtensionPoint: AppExtensionPoint { Identifier("com.apple.accessory-data-provider") Implementing { AccessoryNotifications.NotificationsForwarding { NotificationHandler() } } } } // NotificationHandler sends messages via: let message = AccessoryMessage { AccessoryMessage.Payload(transport: .bluetooth, data: data) } try await session?.sendMessage(message) Info.plist Configuration: EXExtensionPointIdentifier com.apple.accessory-data-provider NSAccessorySetupBluetoothServices FEE0 Questions: What BLE Service and Characteristic should the accessory advertise? - The documentation mentions specifying transport: .bluetooth, but doesn't explain what Service/Characteristic the accessory needs to implement to receive the notification data. 2. How does AccessoryMessage with transport: .bluetooth actually transmit data? - Is there a specific Apple-defined BLE protocol? - Does the accessory need to run specific firmware or support a particular protocol stack? 3. Is there any documentation about the accessory-side implementation? - The iOS-side documentation is clear, but I couldn't find information about what the BLE peripheral needs to implement. 4. Is MFi certification required for the accessory? - The documentation doesn't explicitly mention MFi, but it's unclear if custom third-party accessories can use this framework. Any guidance on how the BLE communication works under the hood would be greatly appreciated.

Live Caller ID Lookup: does iOS call /queries even when the number is in Contacts?
Hi! We’ve had Live Caller ID Lookup in production for a while. We’re seeing backend RPS on our /queries endpoint much higher than our expected incoming call volume. While testing with Console.app during an incoming call, it looks like iOS may still hit our service even when the caller number is already in the user’s Contacts - but I’m not 100% sure from logs alone. Can you confirm: Does iOS invoke Live Caller ID Lookup (i.e. call /queries) for every incoming call, including calls from saved Contacts? If yes, is this simply expected framework behavior? Thanks!

Active Quicklook extension is ignored
When you have multiple Apps on the Mac which all provide Quicklook extensions for the same file type, then I would assume that if I activate one of these Quicklook extensions in the system settings, this one would be used. But this doesn't seem to be the case. It looks like the macOS just looks the very first extension it can find for a certain file type, and if this Quicklook extension is switched off, the file can not be previewed anymore. The macOS just doesn't bother to look for the other existing quicklook extension for this file, even if this other is enabled. The only option right now to get this other extension to be used by the system would be to completely delete the first App, so its extension is deleted as well. Is this really the way how it is supposed to work? How can this be fixed? Can I tell my users something else than "just delete the other App"?

Network extension caused network access to slow down or fail.
Hi, On macOS 26.4 Beta (25E5218f) (macOS Tahoe 26 Developer Beta ), the network filter causes network failures or slowdowns. This manifests as Chrome failing to access websites, while Safari can access the same websites without issue. The affected websites can be pinged locally. My situation is similar to this situation.The same question link is: https://github.com/objective-see/LuLu/issues/836 Have you been paying attention to this issue? Hopefully, it can be fixed in the official release. Thank you.

Background Upload Extension Bug on iOS 26.2
While implementing the new background backup feature introduced in iOS 26.1, I create a PHAssetResourceUploadJob in an Extension. On iOS 26.1, the system successfully triggers the upload. However, on iOS 26.2, although the job is created successfully and all related configurations are correctly set, the system does not trigger the upload. Could you please help confirm the cause of this issue? Thank you.

Safely updating an FSKit module via the Mac App Store
I'm trying to test the update process for an app containing an FSKit module that I'm distributing on the Mac App Store. (I'm also distributing the same app directly with Developer ID, but here I'll focus on App Store because that's the behavior I've been looking at first.) To do that I'm using an internal tester group on TestFlight and then testing an update with TestFlight. Below is the behavior I'm seeing on macOS 15.7.2 (24G325). I've noticed that if an app update is triggered while a disk is mounted using the FSKit extension, the disk is automatically unmounted without warning (FB21287341). That's already undesirable itself in my opinion, but on top of the unmount, there are two other problems: That unmount doesn't seem to be a "clean" unmount and doesn't call functions like synchronize (FB21287688). Now, in my case, my app only provides read-only access, so that doesn't actually matter much in my case. However, I'd imagine if I were to add write access at some point in the future, this would go from "doesn't matter" to "very bad." I've seen a few cases where quitting or crashing the FSModule process while a volume is mounted without actually doing a clean unmount causes a lot of "disk-related actions" (for lack of a better term) to freeze (FB21305906). For example, a use of the mount(8) command or trying to mount a disk at all freezes, and opening Disk Utility stalls on a "Loading disks" spinning indicator. This happens until the Mac is rebooted. I did notice this issue once while testing updates via TestFlight a few times. The same applies if I simply delete the app with Finder instead of updating it. Is there a way to prevent the extension's process from terminating in this case and/or another workaround I could use without waiting for a macOS update to hopefully change this behavior? And does observing this kind of behavior with TestFlight's update behavior suggest the same thing could happen on the App Store with its automatic updates? I'm concerned that pushing an update via the App Store will unexpectedly unmount disks or cause the system-wide issues described in FB21305906 at a random time, which is a pretty big disruption for users.

The app extension cannot access MDM deployed identity via ManagedApp FM
We use Jamf Blueprint to deploy the managed app and identity to the iOS device (iOS 26.3 installed). Our managed app can access the identity via let identityProvider = ManagedAppIdentitiesProvider() let identity: SecIdentity do { identity = try await identityProvider.identity(withIdentifier: "myIdentity") } catch { } However, the app extension cannot access the same identity. Our app extension is notification extension that implemented UNNotificationServiceExtension APIs. We use above code in didReceive() function to access identity that always failed. The MDM configuration payload is: "AppConfig": { "Identities": [ { "Identifier": "myIdentity", "AssetReference": "$PAYLOAD_2" } ] }, "ExtensionConfigs": { "Identifier (com.example.myapp.extension)": { "Identities": [ { "Identifier": "myIdentity", "AssetReference": "$PAYLOAD_2" } ] } }, "ManifestURL": "https://example.net/manifest.plist", "InstallBehavior": { "Install": "Required" } } Is there any problem in our MDM configuration? Or the notification extension cannot integrate with ManagedApp FM?

How does AccessoryMessage with transport: .bluetooth actually transmit data? - Is there a specific Apple-defined BLE protocol? - Does the accessory need to run specific firmware or support a particular protocol stack? 3. Is there any documentation about the accessory-side implementation? - The iOS-side documentation is clear, but I couldn't find information about what the BLE peripheral needs to implement. 4. Is MFi certification required for the accessory? - The documentation doesn't explicitly mention MFi, but it's unclear if custom third-party accessories can use this framework. Any guidance on how the BLE communication works under the hood would be greatly appreciated.

Live Caller ID Lookup: does iOS call /queries even when the number is in Contacts?
Hi! We’ve had Live Caller ID Lookup in production for a while. We’re seeing backend RPS on our /queries endpoint much higher than our expected incoming call volume. While testing with Console.app during an incoming call, it looks like iOS may still hit our service even when the caller number is already in the user’s Contacts - but I’m not 100% sure from logs alone. Can you confirm: Does iOS invoke Live Caller ID Lookup (i.e. call /queries) for every incoming call, including calls from saved Contacts? If yes, is this simply expected framework behavior? Thanks!

Active Quicklook extension is ignored
When you have multiple Apps on the Mac which all provide Quicklook extensions for the same file type, then I would assume that if I activate one of these Quicklook extensions in the system settings, this one would be used. But this doesn't seem to be the case. It looks like the macOS just looks the very first extension it can find for a certain file type, and if this Quicklook extension is switched off, the file can not be previewed anymore. The macOS just doesn't bother to look for the other existing quicklook extension for this file, even if this other is enabled. The only option right now to get this other extension to be used by the system would be to completely delete the first App, so its extension is deleted as well. Is this really the way how it is supposed to work? How can this be fixed? Can I tell my users something else than "just delete the other App"?

Network extension caused network access to slow down or fail.
Hi, On macOS 26.4 Beta (25E5218f) (macOS Tahoe 26 Developer Beta ), the network filter causes network failures or slowdowns. This manifests as Chrome failing to access websites, while Safari can access the same websites without issue. The affected websites can be pinged locally. My situation is similar to this situation.The same question link is: https://github.com/objective-see/LuLu/issues/836 Have you been paying attention to this issue? Hopefully, it can be fixed in the official release. Thank you.

Background Upload Extension Bug on iOS 26.2
While implementing the new background backup feature introduced in iOS 26.1, I create a PHAssetResourceUploadJob in an Extension. On iOS 26.1, the system successfully triggers the upload. However, on iOS 26.2, although the job is created successfully and all related configurations are correctly set, the system does not trigger the upload. Could you please help confirm the cause of this issue? Thank you.

Safely updating an FSKit module via the Mac App Store
I'm trying to test the update process for an app containing an FSKit module that I'm distributing on the Mac App Store. (I'm also distributing the same app directly with Developer ID, but here I'll focus on App Store because that's the behavior I've been looking at first.) To do that I'm using an internal tester group on TestFlight and then testing an update with TestFlight. Below is the behavior I'm seeing on macOS 15.7.2 (24G325). I've noticed that if an app update is triggered while a disk is mounted using the FSKit extension, the disk is automatically unmounted without warning (FB21287341). That's already undesirable itself in my opinion, but on top of the unmount, there are two other problems: That unmount doesn't seem to be a "clean" unmount and doesn't call functions like synchronize (FB21287688). Now, in my case, my app only provides read-only access, so that doesn't actually matter much in my case. However, I'd imagine if I were to add write access at some point in the future, this would go from "doesn't matter" to "very bad." I've seen a few cases where quitting or crashing the FSModule process while a volume is mounted without actually doing a clean unmount causes a lot of "disk-related actions" (for lack of a better term) to freeze (FB21305906). For example, a use of the mount(8) command or trying to mount a disk at all freezes, and opening Disk Utility stalls on a "Loading disks" spinning indicator. This happens until the Mac is rebooted. I did notice this issue once while testing updates via TestFlight a few times. The same applies if I simply delete the app with Finder instead of updating it. Is there a way to prevent the extension's process from terminating in this case and/or another workaround I could use without waiting for a macOS update to hopefully change this behavior? And does observing this kind of behavior with TestFlight's update behavior suggest the same thing could happen on the App Store with its automatic updates? I'm concerned that pushing an update via the App Store will unexpectedly unmount disks or cause the system-wide issues described in FB21305906 at a random time, which is a pretty big disruption for users.

The app extension cannot access MDM deployed identity via ManagedApp FM
We use Jamf Blueprint to deploy the managed app and identity to the iOS device (iOS 26.3 installed). Our managed app can access the identity via let identityProvider = ManagedAppIdentitiesProvider() let identity: SecIdentity do { identity = try await identityProvider.identity(withIdentifier: "myIdentity") } catch { } However, the app extension cannot access the same identity. Our app extension is notification extension that implemented UNNotificationServiceExtension APIs. We use above code in didReceive() function to access identity that always failed. The MDM configuration payload is: "AppConfig": { "Identities": [ { "Identifier": "myIdentity", "AssetReference": "$PAYLOAD_2" } ] }, "ExtensionConfigs": { "Identifier (com.example.myapp.extension)": { "Identities": [ { "Identifier": "myIdentity", "AssetReference": "$PAYLOAD_2" } ] } }, "ManifestURL": "https://example.net/manifest.plist", "InstallBehavior": { "Install": "Required" } } Is there any problem in our MDM configuration? Or the notification extension cannot integrate with ManagedApp FM?
