Minimum achievable latency for ending a Live Activity after app force-kill via APNs push-to-end
Context I'm building a study-timer feature for an iOS app (Flutter + native ActivityKit) that displays a Live Activity on the Lock Screen / Dynamic Island while a session is running. When the user force-quits the app by swiping it up from the App Switcher, I want the Live Activity to disappear as quickly as possible. I have already confirmed (from on-device testing and Apple Developer Forums thread 732418) that: applicationWillTerminate is not called on swipe-up force-kill, only on OS-initiated termination or crash. So synchronous Activity.end(...) from the app itself is not a solution for the force-kill path. Shortening staleDate does not visually dismiss the Live Activity once the app process is gone — the Widget Extension keeps rendering the last fresh snapshot and there is no body-reevaluation trigger on the stale transition post-app-death. (I implemented and verified this, then rolled it back.) The only Apple-official reliable mechanism is APNs push-to-end (Activity.request(pushType: .token) + server sends event: end via APNs). Current architecture I have APNs push-to-end working end-to-end. Structure: Client: Activity.request(pushType: .token), subscribe to Activity.pushTokenUpdates, forward each new token to the backend. Backend: On every client heartbeat, upsert (user_id, la_apns_token, la_activity_id, last_heartbeat) into Postgres. A separate scheduler polls for rows whose last_heartbeat < now() - grace_ttl and sends APNs event: end to the stored token. Parameters I am currently running with: Parameter Value Client heartbeat interval 60 s Orphan grace TTL (server) 135 s (heartbeat × 2.25, to absorb network jitter) Scheduler poll interval 30 s The observation End-to-end latency from "user force-kills the app" to "Live Activity disappears from Lock Screen" is: Worst case: 60 + 135 + 30 = ~225 s (~3.75 min) Typical: ~3 min (as consistently measured on iOS 26.4.1, iPhone 17 Pro Max) Theoretical minimum (if the kill happens exactly at a heartbeat boundary): ~135 s Users perceive 3 minutes as broken — the timer clearly stopped (no ticking), but the Live Activity "ghost" is still visible on the Lock Screen. My question Is there any Apple-supported mechanism to reliably tear down a Live Activity faster than ~2 minutes after the owning app's process is gone, given that applicationWillTerminate does not fire on swipe-kill? Specifically: Is there any practical lower bound below ~60 s for this scenario using the current ActivityKit + APNs model, assuming we are not willing to spam heartbeats every few seconds? I can push heartbeat to 20–30 s, but the server cost grows linearly with active sessions. Does BGAppRefreshTask / BGProcessingTask have any documented lifecycle hook that fires on user-initiated swipe-kill specifically, so that I could do a "last-heartbeat flush" just before the process dies? My understanding is that background tasks are scheduled for later and do not fire synchronously at termination. Is there any signal from APNs/ActivityKit to my server (e.g. a feedback-service-like mechanism) that indicates "this Live Activity's owning app was force-killed", which would let the server short-circuit the heartbeat-based orphan detection? Are there any new APIs in iOS 18.x or the upcoming release that address this specific force-kill → LA-dismissal latency? I could not find anything in the 18.x release notes, but I may have missed it. What I am NOT asking I am not asking how to implement APNs push-to-end (that works). I am not asking about applicationWillTerminate (I already confirmed it does not fire on swipe-kill). I am not asking about shortening staleDate as a visual workaround (I already verified it does not trigger body reevaluation post-kill). Environment iOS 26.4.1 (also reproducible on 18.x devices I have on hand) iPhone 17 Pro Max, iPhone 15 Pro, iPad Air 11-inch (M3) Xcode 26.x Activity.request(pushType: .token) with ActivityContent + custom stalenessInterval = 120s APNs HTTP/2 via token auth (.p8), targeting api.push.apple.com in production apns-push-type: liveactivity, apns-priority: 10, payload includes event: end What I have tried (for the record, to avoid "did you try" responses) applicationWillTerminate with DispatchSemaphore 3.5 s sync wait + dismissalPolicy: .immediate — works only for OS-terminate, not swipe-kill. stalenessInterval = 30s + 15 s refresh cadence + override to 5 s on AppLifecycleState.paused — verified not to dismiss the LA after app death. Cold-start reconciliation via Activity<...>.activities on next app launch — works, but that only helps if the user relaunches. Current APNs push-to-end with 60 s / 135 s / 30 s configuration — works, but latency is the complaint. Any guidance, even "no, ~2 minutes is the floor by design" with a pointer to the relevant doc, would be very helpful. Thank you.

Live Activity updates not received on iPhone 16 Pro Max when started via ActivityKit push
Description When starting Live Activities via ActivityKit push notifications, the “start” notification is received correctly on iPhone 16 Pro Max, but subsequent update or end push notifications are not. The same implementation on iPhone 16 Pro behaves as expected (both start and update/end notifications are delivered and processed). Environment Property Value Device (failing) iPhone 16 Pro Max Device (working) iPhone 16 Pro iOS Version 18.5 Xcode / SDK 16.2/ActivityKit / Push Notifications Network Wi-Fi / Cellular (both tested) Data Collection Method Devices connected via USB. Logs captured using Console.app. Log filtering applied for the liveactivitiesd daemon to isolate Live Activity behavior. Initial Triage/Observations Payload format confirmed compatible; no incompatible fields. APNs token remains the same across messages (no refresh). Identical ActivityKit subscriptions/participants on both devices. Server-side delivery is confirmed: iPhone 16 Pro receives all messages (start, update, end). Only iPhone 16 Pro Max fails to receive update or end push notifications. Log Analysis iPhone 16 Pro (Working) Push-to-Start successfully received: 13:45:20 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:45:20 - Received message: eventType: start(SessionPushNotifications.IncomingMessage.EventType.StartParameters(attributesType: "AchToLSUpgradeAttributes", attributesData: 125 bytes, inputs: [])) 13:45:20 - Created activity: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 13:45:45 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:45:45 - Received message: eventType: end(dismissDate: Optional(2025-07-21 21:00:44 +0000)) 13:45:20 - Activity updated: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 13:45:20 - Local activity did update: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 iPhone 16 Pro Max (Failing) 13:56:39 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:56:39 - Received message: eventType: start(SessionPushNotifications.IncomingMessage.EventType.StartParameters(attributesType: "AchToLSUpgradeAttributes", attributesData: 125 bytes, inputs: [])) 13:56:39 - Created activity: E6BBF691-0C7A-4791-98D2-6F1440D9932E **No subsequent APNs push-to-update or push-to-end messages received.** 13:56:39 - No destinations for event E6BBF691... of type start 13:56:40 - No destinations for event E6BBF691... of type update Questions for Apple Engineering Are there known issues with ActivityKit push notifications specifically on iPhone 16 Pro Max devices? What additional diagnostic logs (system, APNs, liveactivitiesd) would be most helpful to collect? Could device-specific power management, notification settings, or OS-level changes on Pro Max models affect Live Activity updates? Are there differences in how Live Activity push subscriptions or routing are handled on iPhone 16 Pro Max vs Pro that could lead to this issue?

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 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 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!

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 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'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?

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

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...

The APP was not awakened after start a liveactivity
The APP was not awakened by system after start a liveactivity and the liveactivity has showed on lock screen.so the updatetoken wont send to our inner server and the liveactivity can not update,often like this,but sometimes it can work. it makes me confuse,and i don't know how should i can do,because the liveactivity like a black box,i can not analyse the data link.for example ,inner server send a start liveactivity,but it can not accept a updatetoken unless the user lanuch APP. i hope the liveactivity can start and update on background. And i have developed it as described in the document. Hope to get your help,thank you very much.

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].

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!

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.

How to disable highlight state on Link in LA widget
I am working on a Live Activity widget. In it, I want some of the elements to open different deeplink URLs. I have found that assigning multiple widgetURL doesn't work, only one of the URLs gets opened no matter where you tap. I also found that Buttons don't seem to do anything, tapping them actually just open my app as if I just tapped a naked Live Activity. I have found that really only Link elements work if I want to open different URLs upon tapping different elements. And Links are cool and fine, but I am seeing that on tap, my elements become tinted... As in, there is a highlighted state, and it makes the elements inside blue. I have tried to use button style API on a link, but it didn't work. How can I disable the highlighted state for a Link element in a live activity widget?

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

Push-to-Start Live Activity Background Task Issue After App Termination
Desired Behavior I want the app to be able to handle multiple Push-to-Start notifications even when it is completely terminated. Each Live Activity should: Be successfully displayed upon receiving a Push-to-Start notification. Trigger background tasks to send its update token to the server, regardless of the time interval between notifications. Problem I am facing an issue with iOS Live Activities when using Push-to-Start notifications to trigger Live Activities in an app that has been completely terminated. Here’s the detailed scenario: When the app is completely terminated and I send the first Push-to-Start notification: The Live Activity is successfully displayed. didFinishLaunchingWithOptions` is triggered, and background tasks execute correctly, including sending the update token to the server. When I send consecutive Push-to-Start notifications in quick succession (e.g., within a few seconds or minutes): Both notifications successfully display their respective Live Activities. Background tasks are executed correctly for both notifications. However, when there is a longer interval (e.g., 10 minutes) between two Push-to-Start notifications: The first notification works perfectly—it displays the Live Activity, triggers didFinishLaunchingWithOptions, and executes background tasks. The second notification successfully displays the Live Activity but fails to execute any background tasks, such as sending the update token to the server. My HypothesisI suspect that iOS might impose a restriction where background runtime for Push-to-Start notifications can only be granted once within a certain time frame after the app has been terminated. Any insights into why this issue might be occurring or how to ensure consistent background task execution for multiple Push-to-Start notifications would be greatly appreciated!

Minimum achievable latency for ending a Live Activity after app force-kill via APNs push-to-end
Context I'm building a study-timer feature for an iOS app (Flutter + native ActivityKit) that displays a Live Activity on the Lock Screen / Dynamic Island while a session is running. When the user force-quits the app by swiping it up from the App Switcher, I want the Live Activity to disappear as quickly as possible. I have already confirmed (from on-device testing and Apple Developer Forums thread 732418) that: applicationWillTerminate is not called on swipe-up force-kill, only on OS-initiated termination or crash. So synchronous Activity.end(...) from the app itself is not a solution for the force-kill path. Shortening staleDate does not visually dismiss the Live Activity once the app process is gone — the Widget Extension keeps rendering the last fresh snapshot and there is no body-reevaluation trigger on the stale transition post-app-death. (I implemented and verified this, then rolled it back.) The only Apple-official reliable mechanism is APNs push-to-end (Activity.request(pushType: .token) + server sends event: end via APNs). Current architecture I have APNs push-to-end working end-to-end. Structure: Client: Activity.request(pushType: .token), subscribe to Activity.pushTokenUpdates, forward each new token to the backend. Backend: On every client heartbeat, upsert (user_id, la_apns_token, la_activity_id, last_heartbeat) into Postgres. A separate scheduler polls for rows whose last_heartbeat < now() - grace_ttl and sends APNs event: end to the stored token. Parameters I am currently running with: Parameter Value Client heartbeat interval 60 s Orphan grace TTL (server) 135 s (heartbeat × 2.25, to absorb network jitter) Scheduler poll interval 30 s The observation End-to-end latency from "user force-kills the app" to "Live Activity disappears from Lock Screen" is: Worst case: 60 + 135 + 30 = ~225 s (~3.75 min) Typical: ~3 min (as consistently measured on iOS 26.4.1, iPhone 17 Pro Max) Theoretical minimum (if the kill happens exactly at a heartbeat boundary): ~135 s Users perceive 3 minutes as broken — the timer clearly stopped (no ticking), but the Live Activity "ghost" is still visible on the Lock Screen. My question Is there any Apple-supported mechanism to reliably tear down a Live Activity faster than ~2 minutes after the owning app's process is gone, given that applicationWillTerminate does not fire on swipe-kill? Specifically: Is there any practical lower bound below ~60 s for this scenario using the current ActivityKit + APNs model, assuming we are not willing to spam heartbeats every few seconds? I can push heartbeat to 20–30 s, but the server cost grows linearly with active sessions. Does BGAppRefreshTask / BGProcessingTask have any documented lifecycle hook that fires on user-initiated swipe-kill specifically, so that I could do a "last-heartbeat flush" just before the process dies? My understanding is that background tasks are scheduled for later and do not fire synchronously at termination. Is there any signal from APNs/ActivityKit to my server (e.g. a feedback-service-like mechanism) that indicates "this Live Activity's owning app was force-killed", which would let the server short-circuit the heartbeat-based orphan detection? Are there any new APIs in iOS 18.x or the upcoming release that address this specific force-kill → LA-dismissal latency? I could not find anything in the 18.x release notes, but I may have missed it. What I am NOT asking I am not asking how to implement APNs push-to-end (that works). I am not asking about applicationWillTerminate (I already confirmed it does not fire on swipe-kill). I am not asking about shortening staleDate as a visual workaround (I already verified it does not trigger body reevaluation post-kill). Environment iOS 26.4.1 (also reproducible on 18.x devices I have on hand) iPhone 17 Pro Max, iPhone 15 Pro, iPad Air 11-inch (M3) Xcode 26.x Activity.request(pushType: .token) with ActivityContent + custom stalenessInterval = 120s APNs HTTP/2 via token auth (.p8), targeting api.push.apple.com in production apns-push-type: liveactivity, apns-priority: 10, payload includes event: end What I have tried (for the record, to avoid "did you try" responses) applicationWillTerminate with DispatchSemaphore 3.5 s sync wait + dismissalPolicy: .immediate — works only for OS-terminate, not swipe-kill. stalenessInterval = 30s + 15 s refresh cadence + override to 5 s on AppLifecycleState.paused — verified not to dismiss the LA after app death. Cold-start reconciliation via Activity<...>.activities on next app launch — works, but that only helps if the user relaunches. Current APNs push-to-end with 60 s / 135 s / 30 s configuration — works, but latency is the complaint. Any guidance, even "no, ~2 minutes is the floor by design" with a pointer to the relevant doc, would be very helpful. Thank you.

Live Activity updates not received on iPhone 16 Pro Max when started via ActivityKit push
Description When starting Live Activities via ActivityKit push notifications, the “start” notification is received correctly on iPhone 16 Pro Max, but subsequent update or end push notifications are not. The same implementation on iPhone 16 Pro behaves as expected (both start and update/end notifications are delivered and processed). Environment Property Value Device (failing) iPhone 16 Pro Max Device (working) iPhone 16 Pro iOS Version 18.5 Xcode / SDK 16.2/ActivityKit / Push Notifications Network Wi-Fi / Cellular (both tested) Data Collection Method Devices connected via USB. Logs captured using Console.app. Log filtering applied for the liveactivitiesd daemon to isolate Live Activity behavior. Initial Triage/Observations Payload format confirmed compatible; no incompatible fields. APNs token remains the same across messages (no refresh). Identical ActivityKit subscriptions/participants on both devices. Server-side delivery is confirmed: iPhone 16 Pro receives all messages (start, update, end). Only iPhone 16 Pro Max fails to receive update or end push notifications. Log Analysis iPhone 16 Pro (Working) Push-to-Start successfully received: 13:45:20 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:45:20 - Received message: eventType: start(SessionPushNotifications.IncomingMessage.EventType.StartParameters(attributesType: "AchToLSUpgradeAttributes", attributesData: 125 bytes, inputs: [])) 13:45:20 - Created activity: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 13:45:45 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:45:45 - Received message: eventType: end(dismissDate: Optional(2025-07-21 21:00:44 +0000)) 13:45:20 - Activity updated: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 13:45:20 - Local activity did update: 1C081AC5-01AE-4EC0-8B67-5F2A9FAE2D60 iPhone 16 Pro Max (Failing) 13:56:39 - APSXPCDeliverMessageEvent: Created APSIncomingMessage 13:56:39 - Received message: eventType: start(SessionPushNotifications.IncomingMessage.EventType.StartParameters(attributesType: "AchToLSUpgradeAttributes", attributesData: 125 bytes, inputs: [])) 13:56:39 - Created activity: E6BBF691-0C7A-4791-98D2-6F1440D9932E **No subsequent APNs push-to-update or push-to-end messages received.** 13:56:39 - No destinations for event E6BBF691... of type start 13:56:40 - No destinations for event E6BBF691... of type update Questions for Apple Engineering Are there known issues with ActivityKit push notifications specifically on iPhone 16 Pro Max devices? What additional diagnostic logs (system, APNs, liveactivitiesd) would be most helpful to collect? Could device-specific power management, notification settings, or OS-level changes on Pro Max models affect Live Activity updates? Are there differences in how Live Activity push subscriptions or routing are handled on iPhone 16 Pro Max vs Pro that could lead to this issue?

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 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 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!

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 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'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?

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

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...

The APP was not awakened after start a liveactivity
The APP was not awakened by system after start a liveactivity and the liveactivity has showed on lock screen.so the updatetoken wont send to our inner server and the liveactivity can not update,often like this,but sometimes it can work. it makes me confuse,and i don't know how should i can do,because the liveactivity like a black box,i can not analyse the data link.for example ,inner server send a start liveactivity,but it can not accept a updatetoken unless the user lanuch APP. i hope the liveactivity can start and update on background. And i have developed it as described in the document. Hope to get your help,thank you very much.

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!

How to disable highlight state on Link in LA widget
I am working on a Live Activity widget. In it, I want some of the elements to open different deeplink URLs. I have found that assigning multiple widgetURL doesn't work, only one of the URLs gets opened no matter where you tap. I also found that Buttons don't seem to do anything, tapping them actually just open my app as if I just tapped a naked Live Activity. I have found that really only Link elements work if I want to open different URLs upon tapping different elements. And Links are cool and fine, but I am seeing that on tap, my elements become tinted... As in, there is a highlighted state, and it makes the elements inside blue. I have tried to use button style API on a link, but it didn't work. How can I disable the highlighted state for a Link element in a live activity widget?

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

Push-to-Start Live Activity Background Task Issue After App Termination
Desired Behavior I want the app to be able to handle multiple Push-to-Start notifications even when it is completely terminated. Each Live Activity should: Be successfully displayed upon receiving a Push-to-Start notification. Trigger background tasks to send its update token to the server, regardless of the time interval between notifications. Problem I am facing an issue with iOS Live Activities when using Push-to-Start notifications to trigger Live Activities in an app that has been completely terminated. Here’s the detailed scenario: When the app is completely terminated and I send the first Push-to-Start notification: The Live Activity is successfully displayed. didFinishLaunchingWithOptions` is triggered, and background tasks execute correctly, including sending the update token to the server. When I send consecutive Push-to-Start notifications in quick succession (e.g., within a few seconds or minutes): Both notifications successfully display their respective Live Activities. Background tasks are executed correctly for both notifications. However, when there is a longer interval (e.g., 10 minutes) between two Push-to-Start notifications: The first notification works perfectly—it displays the Live Activity, triggers didFinishLaunchingWithOptions, and executes background tasks. The second notification successfully displays the Live Activity but fails to execute any background tasks, such as sending the update token to the server. My HypothesisI suspect that iOS might impose a restriction where background runtime for Push-to-Start notifications can only be granted once within a certain time frame after the app has been terminated. Any insights into why this issue might be occurring or how to ensure consistent background task execution for multiple Push-to-Start notifications would be greatly appreciated!
