FamilyControls Framework Not Working for TestFlight Testers
Hello everyone, I’m developing an app using the FamilyControls framework, I distributed through TestFlight the other day using the “Family Controls” distribution (not Development). Everything works as expected in dev builds — but for external TestFlight testers, nothing in the FamilyControls framework seems to function. I'm using the correct Family Controls capability in Xcode (added via Signing & Capabilities). The com.apple.developer.family-controls entitlement is present in my .entitlements file. All the users who reported the issue had correctly given screen time permissions to the app. Would really appreciate some help regarding where the issue could come from.

ExtendedDistanceMeasurement in Nearby Interaction Framework not working on iOS 26
Problem Description: After upgrading to iOS 26, I discovered that the ExtendedDistanceMeasurement feature in the Nearby Interaction framework is not working as expected. On the same device model, the issue did not occur on iOS 18, but it is present on iOS 26 (including the latest iOS 26.2), and it has started affecting the functionality of my app. I hope this issue can be resolved as soon as possible. Problem Details: On iOS 26 and later versions (including iOS 26.2), when using an iPhone and an Apple Watch both equipped with second-generation UWB chips, enabling isExtendedDistanceMeasurementEnabled initiates the distance measurement process successfully, but the distance information fails to update. The real-time distance between the devices does not display within the app. Affected Devices and Versions: iPhone Model: iPhone 15 Pro Max iOS Version: iOS 26.2 Apple Watch Model: Apple Watch 10 watchOS Version: 26.2 Example Code: The issue can be reproduced by adding the following code to the official sample code: Nearby Interaction Framework Sample Code private func didReceiveDiscoveryToken(_ token: NIDiscoveryToken) { if session == nil { initializeNISession() } if !didSendDiscoveryToken { sendDiscoveryToken() } os_log("running NISession with peer token: \(token)") let config = NINearbyPeerConfiguration(peerToken: token) // The issue can be reproduced by adding the following code to the official sample code // Enable extended distance measurement if both devices support it if NISession.deviceCapabilities.supportsExtendedDistanceMeasurement && token.deviceCapabilities.supportsExtendedDistanceMeasurement { config.isExtendedDistanceMeasurementEnabled = true } session?.run(config) } Problem Behavior: When either the iPhone or the Apple Watch does not support the second-generation UWB chip (i.e., deviceCapabilities.supportsExtendedDistanceMeasurement = false), the code works as expected. However, when both the iPhone and the Apple Watch support the second-generation UWB chip (i.e., deviceCapabilities.supportsExtendedDistanceMeasurement = true), the code fails to work, and the distance does not update — meaning the real-time distance between the devices is not displayed. Expectation: I hope this issue can be resolved soon, as it is impacting my app. The problem persists in the latest iOS 26.2, and has yet to be fixed.

Universal Links not working with subdomains without AASA on root domain
Hi all, I'm trying to set up universal links for my app but it's not working. What I want: cogover.com → Safari (website) - NOT my app *.cogover.com (any subdomain like abc.cogover.com) → My app What I did: Added applinks:*.cogover.com in Xcode Put AASA files on all subdomains They work fine (checked with curl) Problem: All links still open in Safari, not my app. I do not put AASA on my root domain cogover.com because I don't want open my app with root domain. I have checked TN3155: Debugging universal links | Apple Developer Documentation but it only say about universal link works with both root domain and subdomains. Weird thing I found: I checked how Salesforce does it - their *.force.com subdomains work perfectly. But when I tried to check their setup, (https://force.com/.well-known/apple-app-site-association) doesn't seem to exist either! So how does theirs work? Even stranger - Apple's CDN has their file cached at (https://app-site-association.cdn-apple.com/a/v1/force.com) but the actual domain doesn't serve it. Can Apple's CDN have a file cached even if it's not on the website anymore? Thanks for any help!

Declared Age Range - AgeRangeService.Error the operation couldn't be completed
Is there a setting in Settings for None, Ask, or Always for Declared Age? I cannot find anything in iOS 26.2 Settings app, nothing comes up in a search for "age" in Settings. I managed to setup a sandbox apple account (after creating a new email address) and I was able to go to Settings->Developer, login to the sandbox account, and try the various settings for age there, so that much is working. When I call AgeRangeService.shared.requestAgeRange(ageGates: 18, in: presenter) I get "The operation couldn’t be completed. (DeclaredAgeRange.AgeRangeService.Error error 0.)" Is there a way to test this with my regular personal apple unpaid developer account, my work apple developer account with MS SSO, or with the sandbox user? Should I be using requestAgeRange or isEligibleForAgeFeatures? We just have a regular app on the store, it doesn't have chat or anything like that, it's used by licensed truck drivers mostly CDL holders who are 99.99% 18+ in age, possibly some exceptions for 16+ farm drivers. And we would like to stay compliant. Other caveats are that only iOS 26.2 and up are supported, and a judge has blocked the Texas law. Is Apple still supporting the Declared Age Framework or has there been a change?

How long does it take for an Advanced App Clip Experience to be published?
I recently submitted an Advanced App Clip Experience, and the status currently shows as "Received." My default App Clip Experience is already working well, but I need the advanced experience to go live as soon as possible. Does anyone know the typical timeframe for this to be published? Also, will the status change from "Received" to something else when it is fully active? Any insight would be appreciated. Thanks!

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Use VZVirtualMachineView with actor-isolated VZVirtualMachine
We are using VZVirtualMachine instances in a Swift actor. It works fine but we hit a major problem when we decided that we want to attach it to a VZVirtualMachineView to show it / allow user interactions. VZVirtualMachineView and its virtualMachine property is isolated to @MainActor, so if we directly assign our vm instance to it, we receive a concurrency error: @MainActor public func createView() -> VZVirtualMachineView { let view = VZVirtualMachineView() view.virtualMachine = vm // x: Actor-isolated property 'vm' can not be referenced from the main actor return view } Is there any way we can make this work?

Critical CallKit Issue: Audio Route Flapping due to reason: 3 (CategoryChange) after User Toggle
I am facing a severe audio routing instability issue when using CallKit and the Zego Express SDK on iOS. The problem is that the audio route immediately reverts from the Speaker back to the Earpiece, effectively disabling the Speaker button functionality.📝 Observed BehaviorWhen the user taps the native CallKit Speaker Button, the audio route is correctly changed to the Speaker, but then instantly flips back to the Receiver (Earpiece), as shown in the system log captured via AVAudioSession.routeChangeNotification monitoring.🧾 Log Evidence (Flapping Occurs in 0.4 seconds)The following log snippet clearly illustrates the system overriding the user's action (reason: 4) with an unexpected CategoryChange (reason: 3) event: TimestampComponentReason CodeDescriptionRouteIs Speaker16:31:18.009[CallKitManager]4Override (CallKit/ControlCenter)Loa ngoài (Speaker)true16:31:18.411[CallKitManager]3CategoryChangeThiết bị nhận (Receiver)false

iOS 17 CarPlay message notification navigating to app instead of announcing messages
After the update to iOS 17, tapping on message notification shown on CarPlay Dashboard is navigating to the CarPlay app instead of announcing the message notification. Announce Notifications turned ON Announce Messages turned ON Announce New Messages option is selected Other apps message notifications are announced as expected when tapping on the notification implying that the settings are set as required.

Testing Age Assurance
I've been trying to follow Apple's testing age assurance documentation here. After following each step and setting my user as "Texas, child 16-17, significant change declined", the AgeRangeService consistently throws the notAvailable error: do { let response = try await AgeRangeService .shared.requestAgeRange(ageGates: 18, in: self) // ... } catch AgeRangeService.Error.notAvailable { // Always throws this error }

Live Lookup flow stuck at /issue/token-key-for-user-token endpoint
Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream &lt;DER bytes&gt; Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

Contacts Framework CPU Loop (M1 Max / Exchange)
When syncing an Office 365 (Exchange) account on an M1 Max machine running the latest macOS (e.g., Sonoma), the native contactsd and AddressBookManager processes enter a severe, persistent failure loop. The CPU usage spikes from 0.0% to over 80% (observed at 81%) and repeats every 60-90 seconds. This occurs even when the account is entirely empty of contacts and after performing a clean macOS installation, strongly indicating a systemic bug in the framework's Exchange protocol handler on the M1 architecture. System Information Affected Hardware: Apple M1 Max Affected macOS Version: Tahoe 26.1 Affected Processes: contactsd, AddressBookManager Account Type: Microsoft Exchange / Office 365 Steps to Reproduce System Setup: Perform a clean installation of macOS on the M1 Max machine (USB boot, NO Migration Assistant or data restoration). Account Preparation: Ensure the target Exchange account's contacts folder is entirely empty on the server (via Outlook Web Access). Trigger: Go to System Settings > Internet Accounts and add the Exchange account. Ensure ONLY Contacts is toggled ON. Observation: Open Activity Monitor and sort by % CPU. Expected Behavior The contactsd and AddressBookManager processes should spike briefly (under 5%) to establish the empty sync, then settle to a persistent idle state (0.0% to 0.5% CPU). Actual Behavior The processes never settle: CPU Spikes: Usage repeatedly jumps from 0.0% to 81% for AddressBookManager and 22-59% for contactsd. Pattern: This extreme spike lasts for a few seconds before the thread crashes/restarts, and the process immediately re-initiates the loop, consuming massive CPU cycles continuously. Diagnostic Proof The runaway CPU is not caused by corrupt data: Data Neutralization: The account's contacts folder was emptied on the server, yet the high CPU loop persisted when syncing. Clean System: The issue is reproducible on a clean, from-scratch macOS installation, ruling out corrupted user preferences or system files. Cross-Architecture: The exact same account syncs perfectly on iOS and newer M4 Macs, confirming the data is valid and the issue is specific to the M1 Max's implementation of the Exchange protocol handler. Workaround (For Visibility) To restore system performance, the user must DELETE the entire Exchange account from System Settings > Internet Accounts and use a third-party client (e.g., Outlook for Mac) for synchronization, as it bypasses the buggy native framework.

Spotlight App Extension does not persist custom Attributes
We are in the process of updating our legacy Spotlight MDImporter to the new macOS Spotlight App Extension. The transition works well for standard attributes such as title, textContent, and keywords. However, we encounter an issue when adding custom attributes to the CSSearchableItemAttributeSet. These custom attributes are not being persisted, which means they cannot be queried using a Spotlight NSMetadataQuery. Has anyone an idea on how to append custom attributes so that they are included in the indexed file status, as displayed by the shell command mdimport -t -d3 <path> A sample project illustrating the problem is available here: https://www.dropbox.com/scl/fi/t8qg51cr1rpwouxdl900b/2024-09-04-Spotlight-extAttr.zip?rlkey=lg6n9060snw7mrz6jsxfdlnfa&dl=1

Share Age Range Permission - Defect 'Ask Always'
Share Age Range Permission is set to 'Ask First'. Application requested for AgeRange via requestAgeRange API. System presented a consent window where user has to make a choice. User did not acted. Application was pushed to background. Our Application supports PushToTalk Framework and we have successfully joined the channel already. User tapped on the blue-pill , SystemUI will get presented. User tapped on the SystemUI, A New Full Screen SystemUI will get presented. User chosen 'Leave' option and our application left the active channel. 10 User brought the application to foreground and the previous "Share Age Range" system window disappeared. 11. After Step 10, We need to terminate and launch our application in order to get the "Share Age Range" system window. Is "Share Age Range" system window getting disappear is expected here or a BUG

Also, will the status change from "Received" to something else when it is fully active? Any insight would be appreciated. Thanks!

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Use VZVirtualMachineView with actor-isolated VZVirtualMachine
We are using VZVirtualMachine instances in a Swift actor. It works fine but we hit a major problem when we decided that we want to attach it to a VZVirtualMachineView to show it / allow user interactions. VZVirtualMachineView and its virtualMachine property is isolated to @MainActor, so if we directly assign our vm instance to it, we receive a concurrency error: @MainActor public func createView() -> VZVirtualMachineView { let view = VZVirtualMachineView() view.virtualMachine = vm // x: Actor-isolated property 'vm' can not be referenced from the main actor return view } Is there any way we can make this work?

Critical CallKit Issue: Audio Route Flapping due to reason: 3 (CategoryChange) after User Toggle
I am facing a severe audio routing instability issue when using CallKit and the Zego Express SDK on iOS. The problem is that the audio route immediately reverts from the Speaker back to the Earpiece, effectively disabling the Speaker button functionality.📝 Observed BehaviorWhen the user taps the native CallKit Speaker Button, the audio route is correctly changed to the Speaker, but then instantly flips back to the Receiver (Earpiece), as shown in the system log captured via AVAudioSession.routeChangeNotification monitoring.🧾 Log Evidence (Flapping Occurs in 0.4 seconds)The following log snippet clearly illustrates the system overriding the user's action (reason: 4) with an unexpected CategoryChange (reason: 3) event: TimestampComponentReason CodeDescriptionRouteIs Speaker16:31:18.009[CallKitManager]4Override (CallKit/ControlCenter)Loa ngoài (Speaker)true16:31:18.411[CallKitManager]3CategoryChangeThiết bị nhận (Receiver)false

CallKit: Call Blocking for 3rd party apps question
Hi Apple Dev community, I want to ask if CallKit and CXCallDirectoryProvider (with addBlockingEntryWithNextSequentialPhoneNumber) doesn't work for 3rd party Phone apps. Is this a known issue that CallKit doesn't work on 3rd party iOS Phone apps (like WhatsApp, etc)? Thank you.

iOS 17 CarPlay message notification navigating to app instead of announcing messages
After the update to iOS 17, tapping on message notification shown on CarPlay Dashboard is navigating to the CarPlay app instead of announcing the message notification. Announce Notifications turned ON Announce Messages turned ON Announce New Messages option is selected Other apps message notifications are announced as expected when tapping on the notification implying that the settings are set as required. Enabled com.apple.developer.carplay-communication Class CustomCarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnectInterfaceController interfaceController: CPInterfaceController) func scene(_ scene: UIScene, willContinueUserActivityWithType userActivityType: String) }

Testing Age Assurance
I've been trying to follow Apple's testing age assurance documentation here. After following each step and setting my user as "Texas, child 16-17, significant change declined", the AgeRangeService consistently throws the notAvailable error: do { let response = try await AgeRangeService .shared.requestAgeRange(ageGates: 18, in: self) // ... } catch AgeRangeService.Error.notAvailable { // Always throws this error }

Live Lookup flow stuck at /issue/token-key-for-user-token endpoint
Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream &lt;DER bytes&gt; Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

Contacts Framework CPU Loop (M1 Max / Exchange)
When syncing an Office 365 (Exchange) account on an M1 Max machine running the latest macOS (e.g., Sonoma), the native contactsd and AddressBookManager processes enter a severe, persistent failure loop. The CPU usage spikes from 0.0% to over 80% (observed at 81%) and repeats every 60-90 seconds. This occurs even when the account is entirely empty of contacts and after performing a clean macOS installation, strongly indicating a systemic bug in the framework's Exchange protocol handler on the M1 architecture. System Information Affected Hardware: Apple M1 Max Affected macOS Version: Tahoe 26.1 Affected Processes: contactsd, AddressBookManager Account Type: Microsoft Exchange / Office 365 Steps to Reproduce System Setup: Perform a clean installation of macOS on the M1 Max machine (USB boot, NO Migration Assistant or data restoration). Account Preparation: Ensure the target Exchange account's contacts folder is entirely empty on the server (via Outlook Web Access). Trigger: Go to System Settings > Internet Accounts and add the Exchange account. Ensure ONLY Contacts is toggled ON. Observation: Open Activity Monitor and sort by % CPU. Expected Behavior The contactsd and AddressBookManager processes should spike briefly (under 5%) to establish the empty sync, then settle to a persistent idle state (0.0% to 0.5% CPU). Actual Behavior The processes never settle: CPU Spikes: Usage repeatedly jumps from 0.0% to 81% for AddressBookManager and 22-59% for contactsd. Pattern: This extreme spike lasts for a few seconds before the thread crashes/restarts, and the process immediately re-initiates the loop, consuming massive CPU cycles continuously. Diagnostic Proof The runaway CPU is not caused by corrupt data: Data Neutralization: The account's contacts folder was emptied on the server, yet the high CPU loop persisted when syncing. Clean System: The issue is reproducible on a clean, from-scratch macOS installation, ruling out corrupted user preferences or system files. Cross-Architecture: The exact same account syncs perfectly on iOS and newer M4 Macs, confirming the data is valid and the issue is specific to the M1 Max's implementation of the Exchange protocol handler. Workaround (For Visibility) To restore system performance, the user must DELETE the entire Exchange account from System Settings > Internet Accounts and use a third-party client (e.g., Outlook for Mac) for synchronization, as it bypasses the buggy native framework.

Spotlight App Extension does not persist custom Attributes
We are in the process of updating our legacy Spotlight MDImporter to the new macOS Spotlight App Extension. The transition works well for standard attributes such as title, textContent, and keywords. However, we encounter an issue when adding custom attributes to the CSSearchableItemAttributeSet. These custom attributes are not being persisted, which means they cannot be queried using a Spotlight NSMetadataQuery. Has anyone an idea on how to append custom attributes so that they are included in the indexed file status, as displayed by the shell command mdimport -t -d3 <path> A sample project illustrating the problem is available here: https://www.dropbox.com/scl/fi/t8qg51cr1rpwouxdl900b/2024-09-04-Spotlight-extAttr.zip?rlkey=lg6n9060snw7mrz6jsxfdlnfa&dl=1

Share Age Range Permission is set to 'Ask First'. Application requested for AgeRange via requestAgeRange API. System presented a consent window where user has to make a choice. User did not acted. Application was pushed to background. Our Application supports PushToTalk Framework and we have successfully joined the channel already. User tapped on the blue-pill , SystemUI will get presented. User tapped on the SystemUI, A New Full Screen SystemUI will get presented. User chosen 'Leave' option and our application left the active channel. 10 User brought the application to foreground and the previous "Share Age Range" system window disappeared. 11. After Step 10, We need to terminate and launch our application in order to get the "Share Age Range" system window. Is "Share Age Range" system window getting disappear is expected here or a BUG
