iOS26 Live Activity always display in Dark Mode
Hi, We design a Live Activity for our app.We find that in iOS26 system, the widget can not display the correct system display model(Light mode or dark mode), always display with dark mode. When our app run in other system ,such as iOS 17, iOS18 ,it work fine. I find other developer had post a topic three month ago , but it seems there is not any new response about the feedback. https://developer.apple.com/forums/thread/799684?answerId=857377022#857377022 Anyone have idea? Thanks . Below is my code template: struct BroadcastLiveActivityBackgroundView: View { @Environment(\.colorScheme) var colorScheme: ColorScheme var body:some View { LinearGradient( stops: [ Gradient.Stop(color: LiveActivityColor.backgroundColors(self.colorScheme).last!, location: 0.00), Gradient.Stop(color: LiveActivityColor.backgroundColors(self.colorScheme).first!, location: 1.00), ], startPoint: UnitPoint(x: 1, y: 0), endPoint: UnitPoint(x: 0.82, y: 1.11) ) } }

Live Activity triggered by AlarmKit remains as an empty state
I configured my app to show a Live Activity when an alarm rings using AlarmKit. However, if I dismiss the Live Activity by tapping somewhere other than the X button, and then long-press the Dynamic Island, a new Live Activity appears that is long but contains no information. Currently, the only way I can remove this empty Live Activity is to press the X button while the alarm is in the snooze state. Pressing the X button on the initial alarm does not remove it. Is there any way to prevent this behavior or properly handle / clean up this empty Live Activity?

Can LiveActivityIntent open the app when tapping a Live Activity button on Lock Screen & Dynamic Island expanded view?
I’m implementing a Live Activity that shows some text and a button. When the user taps the button, I want to open the host app. What I’ve done so far: Implemented a LiveActivityIntent to handle the button tap. The intent is triggered successfully. However, the app does not open by using deep link/universal app link. From what I can tell, LiveActivityIntent seems limited to system/background execution and doesn’t bring the app to the foreground. Questions: Is it possible for a LiveActivityIntent to open the app? Is this behavior a documented/intentional limitation? If not supported, is using a Universal Link or deep link the recommended solution for opening the app from a Live Activity button? Any official clarification or recommended best practice would be helpful.

Local Updates to Live Activities ignored after push update
I'm building out a live activity that has a button which is meant to update the content state of the Live Activity. It calls a LiveActivityIntent that runs in the app process. The push server starts my live activity and the buttons work just fine. I pass the push token back to the server for further updates and when the next update is pushed by the server the buttons no longer work. With the debugger I'm able to verify the app intent code runs and passes the updated state to the activity. However the activity never updates or re-renders. There are no logs in Xcode or Console.app that indicates what the issue could be or that the update is ignored. I have also tried adding the frequent updates key to my plist with no change. I'm updating the live activity in the LiveActivityIntent like this: public func perform() async throws -> some IntentResult { let activities = Activity<WidgetExtensionAttributes>.activities for activity in activities { let currentState = activity.content.state let currentIndex = currentState.pageIndex ?? 0 let maxIndex = max(0, currentState.items.count - 1) let newIndex: Int if forward { newIndex = min(currentIndex + 1, maxIndex) } else { newIndex = max(currentIndex - 1, 0) } var newState = currentState newState.pageIndex = newIndex await activity.update( ActivityContent( state: newState, staleDate: nil ), alertConfiguration: nil, timestamp: Date() ) } return .result() } To sum up: Push to start -> tap button on activity -> All good! Push to start -> push update -> tap button -> No good...

Intended Flow of Invalidating the pushToStartToken When User Logs Out
Hi, we start and update Live Activities with ActivityKit push notifications in our app, but want to do so only if the user is logged in. Therefore we only send the pushToStartToken to the server when a user logs in (or when the token changed and the user is still logged in.) When the user logs out, we remove that start token from our server so that no LA can be started while the app is in the logged out state. This means that the logout isn't happening immediately but is waiting for that deletion request to succeed. This could also fail and lead to the use rnot being able to log out, e.g. if the user has no internet access. If that deletion request would be fire and forget, we would end up in a state where the server still has the token and might start LAs without any user being logged in. The token flow for Remote Push Notifications is different, on the other hand: requesting a token asynchronously via UIApplication.shared.registerForRemoteNotifications() but invalidating it synchronously (at least from the app's perspective) on logout via UIApplication.shared.unregisterForRemoteNotifications(), which makes it way easier for us to make sure the app does not get notifications when no user is logged in. We're wondering if we're just holding it wrong or if our way of handling the LA token deletion is indeed the intended one?

Background scanning for Bluetooth advertisements with LiveActivities on ios26
Hi, I am trying to understand if I am able to get bluetooth scanning for advertisements (no service UUID) when the app is moved into the background and the screen goes to sleep. I am using swift on ios26.2 with a bluetooth class that uses the standard centralManager.scanForPeripherals to listen for particular Beacons. Testing on a real iPhone 15 this works fine whilst in the foreground, and also when on the lock screen. I am trying to get this to continue working in the background when the black screen sleep mode is on. I have the bluetooth 'Uses Bluetooth LE accessories' in the background modes (as well as Audio, Airplay..) and the necessary Bluetooth peripheral usage description, bluetooth always usage descriptions in info.plist. I launch a LiveActivity whilst the app is in the foreground and bluetooth has started scanning. From my understanding of core bluetooth with ios26 the LiveActivity should allow the scan to continue (without service UUIds and aggressive throttling) whilst the app is in the background. Well this seems to work fine.. if I press the side button the phone goes to the Lock Screen, and whilst on the Lock Screen the bluetooth is scanning fine and receiving beacon data. Similarly if the app is sent to the background behind a different foreground app it also works. As soon as the screen goes to sleep however (after only a few seconds of inactivity on the Lock Screen) then all bluetooth scanning stops. If I click back on the screen and bring the Lock Screen up, then scanning resumes again. Now is it possible to continue the scanning whilst the phone is in sleep mode (i.e. black screen)? Are there any additional acceptable steps to make the bluetooth scanning continue when the screen has gone to sleep. Or is it part of the design with core bluetooth that the 'continues in the background' feature only applies to the lock screen and when other active apps are brought to the foreground on an open phone. I want to understand the limitations of what can be achieved so I am not chasing unachievable objectives. Thanks

Wanted: Live Activities, only on iOS (No remote iOS Live Activities)
I have a Live Activity on iOS. Love it. However, that Live Activity via remote hosting (I'm not building for other targets) shows the Live Activity on watchOS, macOS and CarPlay. disfavoredLocations are for widgets, but I don't appear to have a method to limit or provide exclusive locations the live activity should appear.

Live Activity appears briefly then disappears with "Content load failed: unable to find or unarchive file" error
Hi everyone, I’m implementing Live Activities in my iOS app and encountering an issue when starting a Live Activity via an APNS push. The Live Activity card appears on the Lock Screen / Dynamic Island for a moment, then immediately disappears. In the console, I see the following error: Content load failed: unable to find or unarchive file for key: [com.meituan.imeituan-beta::com.meituan.imeituan-beta.liveactivity:Attributes type: SAKUniversalReminderAttributes:6DBCC2DC-E613-48F5-B97F-3EF72AA0877B]:[w:fix-374.00-h:dyn-64.00-160.00-cr:23.5-s:1.0.fam:medium].

I’ve verified that the attributes and content state types match the ones defined in the app, and the app is built with the correct entitlements.This happens on my iPhone 17 Pro device. Has anyone encountered a similar issue? Could it be related to the archive file not being written correctly by the system, or perhaps a mismatch in the activity attributes? Any guidance on debugging or resolving this would be greatly appreciated. Thank you!

Prevent Live Activity from appearing on Apple Watch
Hello, I’m working on an iOS app where we have integrated ActivityKit to support Live Activities. Our app currently supports iOS 16.x and above, and we do not have an Apple Watch app or watchOS support. However, we noticed that when a Live Activity starts on the iPhone, it automatically appears on the Apple Watch as well. Since our app is not designed for Apple Watch, we would like to prevent the Live Activity UI from appearing on the watch. My questions: Is there any way to disable or prevent Live Activities from showing on Apple Watch via code? Are there any configuration options in ActivityKit or Widget configuration that can restrict Live Activities to iPhone only? Our current setup: Minimum iOS version: 16.x Using ActivityKit for Live Activities No watchOS target in the app Any guidance or recommended approach would be greatly appreciated. Thanks

Can't create a Live Activity from background
Our app is using the CLLocationManager to wake up the app near an iBeacon and then tries to connect to the accessory via bluetooth and UWB. For this to work in the background we need to create a Live Activity and show the user that the app is doing something. When the app is in the foreground or just recently got into the inactivity mode this works fine and we can use CoreBluetooth/NearbyInteraction even when the app then enters the background mode. But when the app is longer in the background creating a Live Activity via Activity.request() throws an ActivityAuthorizationError.visibility. According to the documentation the LiveActivityIntent is able to workaround this background restriction but I get the same exception when I create the LiveActivity from the perform() method. Is there another API to create Live Activities? Do I need to prepare the LiveActivityIntent somehow?

AlarmKit leaves an empty zombie Live Activity in Dynamic Island after swipe-dismiss while unlocked
Hi, We are the developers of Morning Call (https://morningcall.info), and we believe we may have identified an AlarmKit / system UI bug on iPhone. We can reproduce the same behavior not only in our app, but also in Apple’s official AlarmKit sample app, which strongly suggests this is a framework or system-level issue rather than an app-specific bug. Demonstration Video of producing zombie Live Activity https://www.youtube.com/watch?v=cZdF3oc8dVI Related Thread https://developer.apple.com/forums/thread/812006 https://developer.apple.com/forums/thread/817305 https://developer.apple.com/forums/thread/807335 Environment iPhone with Dynamic Island Alarm created using AlarmKit Device is unlocked when the alarm begins alerting Steps to reproduce Schedule an AlarmKit alarm. Wait for the alarm to alert while the device is unlocked. The alarm appears in Dynamic Island. Instead of tapping the intended stop or dismiss button, swipe the Dynamic Island presentation away. Expected result The alarm should be fully dismissed. The Live Activity should be removed. No empty UI should remain in Dynamic Island. Actual result The assigned AppIntent runs successfully. Our app code executes as expected. AlarmKit appears to stop the alarm correctly. However, an empty “zombie” Live Activity remains in Dynamic Island indefinitely. The user cannot clear it through normal interaction. Why this is a serious user-facing issue This is not just a cosmetic issue for us. From the user’s perspective, it looks like a Live Activity is permanently stuck in Dynamic Island. More importantly: Force-quitting the app does not remove it Deleting the app does not remove it In practice, many users conclude that our app has left a broken Live Activity running forever We receive repeated user complaints saying that the Live Activity “won’t go away” Because the remaining UI appears to be system-owned, users often do not realize that the only reliable recovery is to restart the phone. Most users do not discover that workaround on their own, so they instead assume the app is severely broken. Cases where the zombie state disappears Rebooting the phone Waiting for the next AlarmKit alert, then pressing the proper stop button on that alert Additional observations Inside our LiveActivityIntent, calling AlarmManager.shared.stop(id:) reports that the alarm has already been stopped by the system. We also tried inspecting Activity<AlarmAttributes<...>>.activities and calling end(..., dismissalPolicy: .immediate), but in this state no matching activity is exposed to the app. This suggests that the alarm itself has already been stopped, but the system-owned Live Activity UI is not being cleaned up correctly after the swipe-dismiss path. Why this does not appear to be an app logic issue The intent is invoked successfully. The alarm stop path is reached. The alarm is already considered stopped by the system. The remaining UI appears to be system-owned. The stuck UI persists even after our own cleanup logic has run. The stuck UI also survives app force-quit and app deletion.

Urgent
I am developing a productivity app called "FocusPact" using the Screen Time API (Family Controls). Current Status: The parent app bundle ID (com.hayashikento.FocusPact) has already been approved for the Family Controls (Distribution) entitlement. I have recently submitted a new request for the DeviceActivityMonitorExtension bundle ID: com.hayashikento.FocusPact.FocusPActMonitor. The Issue: Currently, the extension only works while debugging with Xcode (Development entitlement). When the device is disconnected, the intervalWillEndWarning and intervalDidEnd triggers are ignored by the system because the Extension ID lacks the Distribution entitlement. This is a critical blocker for my MVP testing phase on TestFlight, as I cannot verify the core "automatic re-blocking" logic in a real-world environment. Request: Could any Apple staff or engineers help expedite the linking of this extension ID to my existing approved entitlement? Parent App ID: com.hayashikento.FocusPact Extension ID: com.hayashikento.FocusPact.FocusPActMonitor I would greatly appreciate any guidance or assistance to resolve this so I can proceed with user testing. Thank you.

Live Activity works perfectly on Simulator but fails on physical device: "No asset provider bundle ID provided"
Hello community, I am implementing a Live Activity for my existing App Store app. The Live Activity works perfectly on the iOS Simulator, but it completely fails to appear on the physical device's lock screen. When I call Activity.request, it succeeds and returns a valid Activity ID, but the physical device's console immediately outputs the following errors from liveactivitiesd: liveactivitiesd is not entitled to specify a scene target. Defaulting containingProcess target to liveactivitiesd No asset provider bundle ID provided I have spent days debugging this and have tried every known workaround. Here is the comprehensive list of what I have already verified and attempted: Environment: Xcode: 16.4 iOS Device: iPhone 13 mini, iOS 26.3.1 macOS: Sequoia 15.6 What I have verified/tried (to avoid duplicate suggestions): NSSupportsLiveActivities: It is set to YES in the main app's Info.plist. I also tried adding it to the Widget Extension's Info.plist just in case. App Icons: The main app has a valid AppIcon set in Assets.xcassets. The Primary App Icon Set Name in Build Settings is correctly set to AppIcon. Bundle IDs: They match perfectly (com.mycompany.app and com.mycompany.app.MyWidget). Version & Build Numbers: The main app and the Widget Extension have exactly the same Version and Build numbers. App Groups & Entitlements: Checked and perfectly synced between the main app and the extension. Dummy Widget: Since it's a Live-Activity-only extension, I added a standard static DummyWidget to the WidgetBundle to prevent the known iOS 17 bug where the system ignores extensions without home screen widgets. Memory/Sanitizers: Ensured Address Sanitizer and Zombie Objects are completely disabled in the Scheme to prevent the 30MB memory limit crash on the device. Nuclear Option: Completely deleted the Widget Extension target, wiped DerivedData, restarted the Mac and iPhone, and recreated the extension from scratch. Minimal UI Test: Replaced the widget's UI with a simple Text("Test") to rule out any SwiftUI rendering crashes. Device Settings: Verified that "Live Activities" is enabled under "Face ID & Passcode" settings on the physical iPhone. Despite all of this, the Simulator works flawlessy, while the device throws No asset provider bundle ID provided and shows nothing. Does anyone know what specific condition causes liveactivitiesd to fail to find the asset provider (the parent app) on a physical device for an existing app? Are there any undocumented provisioning profile quirks or obscure Build Settings I might be missing? Any insights would be deeply appreciated. Thank you!

Live Activity Not Updating Frequently for Offline Music App (Lyrics Sync Issue)
Hi everyone, I’m currently implementing Live Activities in my music app to display real-time lyrics on the Lock Screen. The app works fully offline, so I’m not using push updates or push tokens. Instead, I’m updating the Live Activity locally as each new line of lyrics is played (essentially near real-time updates synced with the song). However, I’m running into an issue where the Live Activity UI is not updating reliably or frequently enough. Even though I’m calling the update method for each lyric line, the changes are either delayed or not reflected at all. Here’s some additional context: • The app runs fine in the background (verified via battery usage and playback behavior) • Live Activity is successfully created and initially displayed • Updates are triggered locally (no push notifications involved) • Updates are happening quite frequently (per lyric line) • No crashes or errors are observed My questions: 1. Is there a system-imposed throttling limit on how frequently Live Activities can be updated locally? 2. Are there recommended update intervals for smooth UI updates (e.g., for use cases like lyrics or timers)? 3. Does Live Activity deprioritize updates for offline apps or background execution? 4. Are there any additional configurations or capabilities required to ensure consistent updates? 5. Is using something like AsyncStream or other concurrency patterns helpful in this case? 6. Are there any undocumented limitations or best practices for high-frequency updates? 7. Is there any private or internal API used by Apple apps (like Music) that allows smoother real-time updates? My goal is to achieve smooth, near real-time lyric updates similar to Apple Music’s Now Playing experience. Any guidance, best practices, or clarification would be greatly appreciated. Thanks in advance!

Live Activity Silent Rendering Failure- Any Way to Detect Crash / Failure State?
Hi Apple Team, We are facing an issue with Live Activities where the UI intermittently fails to render and shows a loader or blank state. After extensive debugging, we’ve identified that the failure happens during the rendering phase inside the system process (WidgetKit / liveactivitiesd), but there are no actionable signals exposed to the app. Problem: Live Activity launches successfully After a few updates or under certain UI conditions, it: stops rendering shows a loader / blank UI sometimes disappears No crash logs are generated No MetricKit diagnostics available for the extension Console logs show: Invalid frame dimension (negative or non-finite) Archive was nil. LiveActivity will be empty Sometimes because of memory pressure too The extension process appears to terminate silently Challenge Currently, there is no way to detect from the app side that: the Live Activity has failed to render the extension process has crashed/terminated the UI is no longer being updated Questions Is there any callback, delegate, or lifecycle hook that notifies when: a Live Activity rendering fails the extension process crashes or is terminated by the system? Is there any recommended way to detect a “broken” Live Activity state (e.g., stuck loader / non-updating UI)? Are there any diagnostic APIs or logs we can rely on in production to identify such failures? Is this considered expected behavior under certain system constraints (e.g., memory/rendering limits), and if so, are there guidelines to proactively detect or mitigate it? Goal We want to: proactively detect Live Activity failure log it for monitoring optionally fallback or recover gracefully Additional context: We fixed all the issues and the live activity is pretty stable. But asking for methods to track & fix such cases.

Live Activity triggered by AlarmKit remains as an empty state
I configured my app to show a Live Activity when an alarm rings using AlarmKit. However, if I dismiss the Live Activity by tapping somewhere other than the X button, and then long-press the Dynamic Island, a new Live Activity appears that is long but contains no information. Currently, the only way I can remove this empty Live Activity is to press the X button while the alarm is in the snooze state. Pressing the X button on the initial alarm does not remove it. Is there any way to prevent this behavior or properly handle / clean up this empty Live Activity?

Local Updates to Live Activities ignored after push update
I'm building out a live activity that has a button which is meant to update the content state of the Live Activity. It calls a LiveActivityIntent that runs in the app process. The push server starts my live activity and the buttons work just fine. I pass the push token back to the server for further updates and when the next update is pushed by the server the buttons no longer work. With the debugger I'm able to verify the app intent code runs and passes the updated state to the activity. However the activity never updates or re-renders. There are no logs in Xcode or Console.app that indicates what the issue could be or that the update is ignored. I have also tried adding the frequent updates key to my plist with no change. I'm updating the live activity in the LiveActivityIntent like this: public func perform() async throws -> some IntentResult { let activities = Activity<WidgetExtensionAttributes>.activities for activity in activities { let currentState = activity.content.state let currentIndex = currentState.pageIndex ?? 0 let maxIndex = max(0, currentState.items.count - 1) let newIndex: Int if forward { newIndex = min(currentIndex + 1, maxIndex) } else { newIndex = max(currentIndex - 1, 0) } var newState = currentState newState.pageIndex = newIndex await activity.update( ActivityContent( state: newState, staleDate: nil ), alertConfiguration: nil, timestamp: Date() ) } return .result() } To sum up: Push to start -> tap button on activity -> All good! Push to start -> push update -> tap button -> No good...

Intended Flow of Invalidating the pushToStartToken When User Logs Out
Hi, we start and update Live Activities with ActivityKit push notifications in our app, but want to do so only if the user is logged in. Therefore we only send the pushToStartToken to the server when a user logs in (or when the token changed and the user is still logged in.) When the user logs out, we remove that start token from our server so that no LA can be started while the app is in the logged out state. This means that the logout isn't happening immediately but is waiting for that deletion request to succeed. This could also fail and lead to the use rnot being able to log out, e.g. if the user has no internet access. If that deletion request would be fire and forget, we would end up in a state where the server still has the token and might start LAs without any user being logged in. The token flow for Remote Push Notifications is different, on the other hand: requesting a token asynchronously via UIApplication.shared.registerForRemoteNotifications() but invalidating it synchronously (at least from the app's perspective) on logout via UIApplication.shared.unregisterForRemoteNotifications(), which makes it way easier for us to make sure the app does not get notifications when no user is logged in. We're wondering if we're just holding it wrong or if our way of handling the LA token deletion is indeed the intended one?

Background scanning for Bluetooth advertisements with LiveActivities on ios26
Hi, I am trying to understand if I am able to get bluetooth scanning for advertisements (no service UUID) when the app is moved into the background and the screen goes to sleep. I am using swift on ios26.2 with a bluetooth class that uses the standard centralManager.scanForPeripherals to listen for particular Beacons. Testing on a real iPhone 15 this works fine whilst in the foreground, and also when on the lock screen. I am trying to get this to continue working in the background when the black screen sleep mode is on. I have the bluetooth 'Uses Bluetooth LE accessories' in the background modes (as well as Audio, Airplay..) and the necessary Bluetooth peripheral usage description, bluetooth always usage descriptions in info.plist. I launch a LiveActivity whilst the app is in the foreground and bluetooth has started scanning. From my understanding of core bluetooth with ios26 the LiveActivity should allow the scan to continue (without service UUIds and aggressive throttling) whilst the app is in the background. Well this seems to work fine.. if I press the side button the phone goes to the Lock Screen, and whilst on the Lock Screen the bluetooth is scanning fine and receiving beacon data. Similarly if the app is sent to the background behind a different foreground app it also works. As soon as the screen goes to sleep however (after only a few seconds of inactivity on the Lock Screen) then all bluetooth scanning stops. If I click back on the screen and bring the Lock Screen up, then scanning resumes again. Now is it possible to continue the scanning whilst the phone is in sleep mode (i.e. black screen)? Are there any additional acceptable steps to make the bluetooth scanning continue when the screen has gone to sleep. Or is it part of the design with core bluetooth that the 'continues in the background' feature only applies to the lock screen and when other active apps are brought to the foreground on an open phone. I want to understand the limitations of what can be achieved so I am not chasing unachievable objectives. Thanks

Wanted: Live Activities, only on iOS (No remote iOS Live Activities)
I have a Live Activity on iOS. Love it. However, that Live Activity via remote hosting (I'm not building for other targets) shows the Live Activity on watchOS, macOS and CarPlay. disfavoredLocations are for widgets, but I don't appear to have a method to limit or provide exclusive locations the live activity should appear.

Live Activity appears briefly then disappears with "Content load failed: unable to find or unarchive file" error
Hi everyone, I’m implementing Live Activities in my iOS app and encountering an issue when starting a Live Activity via an APNS push. The Live Activity card appears on the Lock Screen / Dynamic Island for a moment, then immediately disappears. In the console, I see the following error: Content load failed: unable to find or unarchive file for key: [com.meituan.imeituan-beta::com.meituan.imeituan-beta.liveactivity:Attributes type: SAKUniversalReminderAttributes:6DBCC2DC-E613-48F5-B97F-3EF72AA0877B]:[w:fix-374.00-h:dyn-64.00-160.00-cr:23.5-s:1.0.fam:medium].

I’ve verified that the attributes and content state types match the ones defined in the app, and the app is built with the correct entitlements.This happens on my iPhone 17 Pro device. Has anyone encountered a similar issue? Could it be related to the archive file not being written correctly by the system, or perhaps a mismatch in the activity attributes? Any guidance on debugging or resolving this would be greatly appreciated. Thank you!

Prevent Live Activity from appearing on Apple Watch
Hello, I’m working on an iOS app where we have integrated ActivityKit to support Live Activities. Our app currently supports iOS 16.x and above, and we do not have an Apple Watch app or watchOS support. However, we noticed that when a Live Activity starts on the iPhone, it automatically appears on the Apple Watch as well. Since our app is not designed for Apple Watch, we would like to prevent the Live Activity UI from appearing on the watch. My questions: Is there any way to disable or prevent Live Activities from showing on Apple Watch via code? Are there any configuration options in ActivityKit or Widget configuration that can restrict Live Activities to iPhone only? Our current setup: Minimum iOS version: 16.x Using ActivityKit for Live Activities No watchOS target in the app Any guidance or recommended approach would be greatly appreciated. Thanks

Can't create a Live Activity from background
Our app is using the CLLocationManager to wake up the app near an iBeacon and then tries to connect to the accessory via bluetooth and UWB. For this to work in the background we need to create a Live Activity and show the user that the app is doing something. When the app is in the foreground or just recently got into the inactivity mode this works fine and we can use CoreBluetooth/NearbyInteraction even when the app then enters the background mode. But when the app is longer in the background creating a Live Activity via Activity.request() throws an ActivityAuthorizationError.visibility. According to the documentation the LiveActivityIntent is able to workaround this background restriction but I get the same exception when I create the LiveActivity from the perform() method. Is there another API to create Live Activities? Do I need to prepare the LiveActivityIntent somehow?

AlarmKit leaves an empty zombie Live Activity in Dynamic Island after swipe-dismiss while unlocked
Hi, We are the developers of Morning Call (https://morningcall.info), and we believe we may have identified an AlarmKit / system UI bug on iPhone. We can reproduce the same behavior not only in our app, but also in Apple’s official AlarmKit sample app, which strongly suggests this is a framework or system-level issue rather than an app-specific bug. Demonstration Video of producing zombie Live Activity https://www.youtube.com/watch?v=cZdF3oc8dVI Related Thread https://developer.apple.com/forums/thread/812006 https://developer.apple.com/forums/thread/817305 https://developer.apple.com/forums/thread/807335 Environment iPhone with Dynamic Island Alarm created using AlarmKit Device is unlocked when the alarm begins alerting Steps to reproduce Schedule an AlarmKit alarm. Wait for the alarm to alert while the device is unlocked. The alarm appears in Dynamic Island. Instead of tapping the intended stop or dismiss button, swipe the Dynamic Island presentation away. Expected result The alarm should be fully dismissed. The Live Activity should be removed. No empty UI should remain in Dynamic Island. Actual result The assigned AppIntent runs successfully. Our app code executes as expected. AlarmKit appears to stop the alarm correctly. However, an empty “zombie” Live Activity remains in Dynamic Island indefinitely. The user cannot clear it through normal interaction. Why this is a serious user-facing issue This is not just a cosmetic issue for us. From the user’s perspective, it looks like a Live Activity is permanently stuck in Dynamic Island. More importantly: Force-quitting the app does not remove it Deleting the app does not remove it In practice, many users conclude that our app has left a broken Live Activity running forever We receive repeated user complaints saying that the Live Activity “won’t go away” Because the remaining UI appears to be system-owned, users often do not realize that the only reliable recovery is to restart the phone. Most users do not discover that workaround on their own, so they instead assume the app is severely broken. Cases where the zombie state disappears Rebooting the phone Waiting for the next AlarmKit alert, then pressing the proper stop button on that alert Additional observations Inside our LiveActivityIntent, calling AlarmManager.shared.stop(id:) reports that the alarm has already been stopped by the system. We also tried inspecting Activity<AlarmAttributes<...>>.activities and calling end(..., dismissalPolicy: .immediate), but in this state no matching activity is exposed to the app. This suggests that the alarm itself has already been stopped, but the system-owned Live Activity UI is not being cleaned up correctly after the swipe-dismiss path. Why this does not appear to be an app logic issue The intent is invoked successfully. The alarm stop path is reached. The alarm is already considered stopped by the system. The remaining UI appears to be system-owned. The stuck UI persists even after our own cleanup logic has run. The stuck UI also survives app force-quit and app deletion.

Urgent
I am developing a productivity app called "FocusPact" using the Screen Time API (Family Controls). Current Status: The parent app bundle ID (com.hayashikento.FocusPact) has already been approved for the Family Controls (Distribution) entitlement. I have recently submitted a new request for the DeviceActivityMonitorExtension bundle ID: com.hayashikento.FocusPact.FocusPActMonitor. The Issue: Currently, the extension only works while debugging with Xcode (Development entitlement). When the device is disconnected, the intervalWillEndWarning and intervalDidEnd triggers are ignored by the system because the Extension ID lacks the Distribution entitlement. This is a critical blocker for my MVP testing phase on TestFlight, as I cannot verify the core "automatic re-blocking" logic in a real-world environment. Request: Could any Apple staff or engineers help expedite the linking of this extension ID to my existing approved entitlement? Parent App ID: com.hayashikento.FocusPact Extension ID: com.hayashikento.FocusPact.FocusPActMonitor I would greatly appreciate any guidance or assistance to resolve this so I can proceed with user testing. Thank you.

Live Activity works perfectly on Simulator but fails on physical device: "No asset provider bundle ID provided"
Hello community, I am implementing a Live Activity for my existing App Store app. The Live Activity works perfectly on the iOS Simulator, but it completely fails to appear on the physical device's lock screen. When I call Activity.request, it succeeds and returns a valid Activity ID, but the physical device's console immediately outputs the following errors from liveactivitiesd: liveactivitiesd is not entitled to specify a scene target. Defaulting containingProcess target to liveactivitiesd No asset provider bundle ID provided I have spent days debugging this and have tried every known workaround. Here is the comprehensive list of what I have already verified and attempted: Environment: Xcode: 16.4 iOS Device: iPhone 13 mini, iOS 26.3.1 macOS: Sequoia 15.6 What I have verified/tried (to avoid duplicate suggestions): NSSupportsLiveActivities: It is set to YES in the main app's Info.plist. I also tried adding it to the Widget Extension's Info.plist just in case. App Icons: The main app has a valid AppIcon set in Assets.xcassets. The Primary App Icon Set Name in Build Settings is correctly set to AppIcon. Bundle IDs: They match perfectly (com.mycompany.app and com.mycompany.app.MyWidget). Version & Build Numbers: The main app and the Widget Extension have exactly the same Version and Build numbers. App Groups & Entitlements: Checked and perfectly synced between the main app and the extension. Dummy Widget: Since it's a Live-Activity-only extension, I added a standard static DummyWidget to the WidgetBundle to prevent the known iOS 17 bug where the system ignores extensions without home screen widgets. Memory/Sanitizers: Ensured Address Sanitizer and Zombie Objects are completely disabled in the Scheme to prevent the 30MB memory limit crash on the device. Nuclear Option: Completely deleted the Widget Extension target, wiped DerivedData, restarted the Mac and iPhone, and recreated the extension from scratch. Minimal UI Test: Replaced the widget's UI with a simple Text("Test") to rule out any SwiftUI rendering crashes. Device Settings: Verified that "Live Activities" is enabled under "Face ID & Passcode" settings on the physical iPhone. Despite all of this, the Simulator works flawlessy, while the device throws No asset provider bundle ID provided and shows nothing. Does anyone know what specific condition causes liveactivitiesd to fail to find the asset provider (the parent app) on a physical device for an existing app? Are there any undocumented provisioning profile quirks or obscure Build Settings I might be missing? Any insights would be deeply appreciated. Thank you!

Live Activity Not Updating Frequently for Offline Music App (Lyrics Sync Issue)
Hi everyone, I’m currently implementing Live Activities in my music app to display real-time lyrics on the Lock Screen. The app works fully offline, so I’m not using push updates or push tokens. Instead, I’m updating the Live Activity locally as each new line of lyrics is played (essentially near real-time updates synced with the song). However, I’m running into an issue where the Live Activity UI is not updating reliably or frequently enough. Even though I’m calling the update method for each lyric line, the changes are either delayed or not reflected at all. Here’s some additional context: • The app runs fine in the background (verified via battery usage and playback behavior) • Live Activity is successfully created and initially displayed • Updates are triggered locally (no push notifications involved) • Updates are happening quite frequently (per lyric line) • No crashes or errors are observed My questions: 1. Is there a system-imposed throttling limit on how frequently Live Activities can be updated locally? 2. Are there recommended update intervals for smooth UI updates (e.g., for use cases like lyrics or timers)? 3. Does Live Activity deprioritize updates for offline apps or background execution? 4. Are there any additional configurations or capabilities required to ensure consistent updates? 5. Is using something like AsyncStream or other concurrency patterns helpful in this case? 6. Are there any undocumented limitations or best practices for high-frequency updates? 7. Is there any private or internal API used by Apple apps (like Music) that allows smoother real-time updates? My goal is to achieve smooth, near real-time lyric updates similar to Apple Music’s Now Playing experience. Any guidance, best practices, or clarification would be greatly appreciated. Thanks in advance!

Live Activity Silent Rendering Failure- Any Way to Detect Crash / Failure State?
Hi Apple Team, We are facing an issue with Live Activities where the UI intermittently fails to render and shows a loader or blank state. After extensive debugging, we’ve identified that the failure happens during the rendering phase inside the system process (WidgetKit / liveactivitiesd), but there are no actionable signals exposed to the app. Problem: Live Activity launches successfully After a few updates or under certain UI conditions, it: stops rendering shows a loader / blank UI sometimes disappears No crash logs are generated No MetricKit diagnostics available for the extension Console logs show: Invalid frame dimension (negative or non-finite) Archive was nil. LiveActivity will be empty Sometimes because of memory pressure too The extension process appears to terminate silently Challenge Currently, there is no way to detect from the app side that: the Live Activity has failed to render the extension process has crashed/terminated the UI is no longer being updated Questions Is there any callback, delegate, or lifecycle hook that notifies when: a Live Activity rendering fails the extension process crashes or is terminated by the system? Is there any recommended way to detect a “broken” Live Activity state (e.g., stuck loader / non-updating UI)? Are there any diagnostic APIs or logs we can rely on in production to identify such failures? Is this considered expected behavior under certain system constraints (e.g., memory/rendering limits), and if so, are there guidelines to proactively detect or mitigate it? Goal We want to: proactively detect Live Activity failure log it for monitoring optionally fallback or recover gracefully Additional context: We fixed all the issues and the live activity is pretty stable. But asking for methods to track & fix such cases.
