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?

Some of the users of my app reported that, the widgets cannot be loaded, event after restarts and re-installs. It seems that it is not rare, I have tens of reports on this (and probably much more who didn't report). It seems the widget is blank even on the gallery screen while you are first adding it: struct SingleWidgetProvider: AppIntentTimelineProvider { @Environment(\.widgetFamily) var family private let viewModel: WidgetViewModel = WidgetViewModel() func placeholder(in context: Context) -> SingleEntry { SingleEntry(date: Date(), habit: .singleSample) } func snapshot(for configuration: SingleWidgetConfigurationIntent, in context: Context) async -> SingleEntry { guard let habit = Array(PersistenceManager.shared.retrieveHabitList().habits).first else { return SingleEntry(date: Date(), habit: .singleSample) } let displayable = viewModel.displayableFromHabit(habit, separateComponents: true, secondOffset: 0) return SingleEntry(date: Date(), habit: displayable) } func timeline(for configuration: SingleWidgetConfigurationIntent, in context: Context) async -> Timeline<SingleEntry> { var entries: [SingleEntry] = [] guard let counter = configuration.currentCounter else { return Timeline(entries: [SingleEntry(date: Date(), habit: .singleSample)], policy: .atEnd) } guard let habit = PersistenceManager.shared.retrieveHabit(habitKey: counter.id) else { return Timeline(entries: [SingleEntry(date: Date(), habit: .singleSample)], policy: .atEnd) } let currentDate = Date() for secondOffset in 0 ..< 100 { let displayable = viewModel.displayableFromHabit( habit, separateComponents: true, secondOffset: secondOffset, symbolName: habit.habitSymbol?.name ?? "", overrideColor: configuration.currentColor.color, overrideButtonVisibility: configuration.currentButtonVisibility, overrideDisplayOption: configuration.currentDisplayOption ) let entryDate = Calendar.current.date(byAdding: .second, value: secondOffset, to: currentDate)! let entry = SingleEntry(date: entryDate, habit: displayable) entries.append(entry) } return Timeline(entries: entries, policy: .atEnd) } } struct SingleEntry: TimelineEntry { let date: Date let habit: HabitDisplayable } static var singleSample: HabitDisplayable { return HabitDisplayable(habitKey: nil, title: LS("sampleWidgetHabitTitle"), dates: [Date(timeIntervalSince1970: 1507158360)], displayOption: .dayMonthYear, secondOffset: 0, separateComponents: true) } func displayableFromHabit( _ habit: Habit, separateComponents: Bool, secondOffset: Int, symbolName: String = "", overrideColor: Color? = nil, overrideButtonVisibility: WidgetButtonVisibility? = nil, overrideDisplayOption: WidgetDisplayOption? = nil ) -> HabitDisplayable { let latestDates: [HabitDate] let displayOption: DisplayOption if let overrideDisplayOption { if overrideDisplayOption == .sameAsCounter { displayOption = habit.settings?.toValue.displayOption ?? .dayMonthYear } else { displayOption = DisplayOption(rawValue: overrideDisplayOption.rawValue - 1) ?? .dayMonthYear } } else { displayOption = habit.settings?.toValue.displayOption ?? .dayMonthYear } let displayMode = displayOption.mode switch displayMode { case .timePassed, .date: latestDates = PersistenceManager.shared.latestDate(habit: habit).map { [$0] } ?? [] case .activity: latestDates = PersistenceManager.shared.retrieveHabitDates(habit: habit, limitDate: displayOption.limitDate()) } let displayButton: Bool if let overrideButtonVisibility { if overrideButtonVisibility == .sameAsCounter { displayButton = habit.settings?.toValue.buttonType == .onRow } else { displayButton = overrideButtonVisibility == .show } } else { displayButton = false } return HabitDisplayable( habitKey: habit.habitKey, title: habit.title, dates: latestDates.map { $0.date }, displayOption: displayOption, secondOffset: secondOffset, separateComponents: separateComponents, color: overrideColor ?? habit.habitColor?.color ?? .appPrimary, symbolName: symbolName, displayButton: displayButton ) } I provided a large portion of my code, let me know if you need more. The strange thing here is, even if the DB connection is broken somehow, it should have shown the default option (singleSample). I am not able to reproduce/fix this for months now, so any help is very appreciated.

Hello Apple Developer Technical Support, I’m following up on case #102807413324 and submitting this as a code-level support request. We are integrating iOS Live Activities (ActivityKit + WidgetKit extension written in SwiftUI) into an Expo/React Native app. We’re seeing behavior where the Live Activity UI shown on the Lock Screen appears to “stick” to an older layout and ignores updated SwiftUI code and/or bundled assets, even after rebuilding, reinstalling, and removing existing Live Activities before testing again. Environment Device: iPhone 13 iOS: 26.2 macOS: 15.7.3 (24G419) Xcode: 16.4 (16F6) Expo SDK: 52 React Native: 0.76.9 expo-live-activity: ^0.4.2 Build type: Ad-Hoc signed IPA (EAS local build) Summary We have a WidgetKit extension target (LiveActivity.appex, bundle id: stimul8.LiveActivity) using ActivityConfiguration(for: LiveActivityAttributes.self). The extension contains multiple SwiftUI views selected via a “route” (derived from deepLinkUrl / title / subtitle), and uses images/backgrounds from the extension asset catalog (Assets.xcassets). We also support loading images from an App Group container with a fallback to the asset catalog. After shipping updates, the Live Activity UI shown on the Lock Screen continues to resemble an older/default layout (example: a progress-bar-like element remains visible even after removing ProgressView usage from LiveActivityView.swift). Some custom backgrounds/images also fail to display as expected. Routing (examples) /streak -> StreakLiveActivityView /streak-urgent -> StreakUrgentLiveActivityView /lesson/create -> AILessonLiveActivityView1 /lesson/reminder -> AILessonLiveActivityView2 default -> LiveActivityView Steps to reproduce (high-level) Install/build and trigger a Live Activity. Modify the SwiftUI layout in the extension (e.g., remove ProgressView and change obvious UI elements), rebuild, and reinstall. Remove any existing Live Activities from the Lock Screen, then trigger a new Live Activity again. Observed: Lock Screen Live Activity still renders the prior/older-looking UI and/or ignores updated assets. Troubleshooting already done Verified the extension (LiveActivity.appex) is included in the IPA and properly signed. Verified Assets.car is present in the extension and PNG assets are present in the build artifacts. Ensured SwiftUI source files used by the extension are overwritten during prebuild so the intended versions are present in ios/LiveActivity. Cleared DerivedData related to LiveActivity builds. Reinstalled the app and removed existing Live Activities from the Lock Screen before re-triggering new ones. Questions Is there any known caching behavior where Live Activities can continue to display a previous UI layout after an app/extension update, even when the activity is re-created? Are there recommended steps to force the system to load the newest widget extension binary/UI beyond reinstalling and removing existing Live Activities? What’s the recommended way to confirm which exact extension binary/UI version is being rendered on-device (e.g., specific Console logs, sysdiagnose signals, or other indicators)? Are there any known constraints with Assets.xcassets usage for Live Activities that could cause bundled assets not to render even when present? We can provide A minimal reproduction Xcode project (preferred) The IPA build Build logs (Xcode/EAS) Screenshots/video and a sysdiagnose captured after reproduction Thank you for your guidance. Best regards

Summary A crash occurs in ViewBridge framework when a TUINSRemoteViewController object receives -release message after being deallocated. This appears to be a reference counting issue within the ViewBridge framework's internal autorelease pool management. Environment macOS Version: [15.0.0] Application: Custom Qt-based application using Chromium Embedded Framework (xcode version: xcode 15; QT version: 6.5.4 ; CEF version: 138.0.47+g2728d53+chromium-138.0.7204.221) Steps to Reproduce Users are typically using the app normally, but a crash occasionally occurs when they activate and click on the application. This happens infrequently, but it occurs roughly every day. Currently, only a few specific users experience this crash, and it may appear for several consecutive days before disappearing for several days.

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...

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.

Issue Description: Tapping the app widget sometimes triggers the Universal Link twice, causing duplicate navigation or actions within the app Steps to Reproduce: Add the app widget to the home screen Tap the widget to open the app via the Universal Link Observe that the Universal Link is sometimes fired twice Expected Behavior: Tapping the widget should trigger the Universal Link only once. Actual Behavior: Universal Link is triggered twice, causing duplicate navigation or actions.

Hello everybody! Does anybody know how to set default values for string array intent field provided dynamically? I want to have preset array field values just after widget added I have a simple accessory widget with circular and rectangular representation (the first one is for 1 currency value and the second one is for 3 values). I created CurrencyWidgets.intentdefinition and added AccessoryCurrency custom intent. Here I added string parameter field currencyCode. For this parameter I set the following options: Supports Multiple Values Fixed Size (AccessoryCircular = 1, AccessoryRectangular = 3) User can edit value in Shortcuts Options are provided dynamically Then I created CurrencyTypeIntent extension and added IntentHandler for my custom intent AccessoryCurrency. The code is below class IntentHandler: INExtension, AccessoryCurrencyIntentHandling { override func handler(for intent: INIntent) -> Any { self }     func provideCurrencyCodeOptionsCollection(for intent: AccessoryCurrencyIntent) async throws -> INObjectCollection<NSString> {         return INObjectCollection(items: [NSString("USD"), NSString("EUR"), NSString("RUB"), NSString("CNY")])    } func defaultCurrencyCode(for intent: AccessoryCurrencyIntent) -> [String]? {      return ["USD", "EUR", "RUB"]    } } The problem is in func defaultCurrencyCode(...): when I return something except nil (for example ["USD"] or ["USD", "EUR", "RUB"]) then I got a broken widget. It hangs in a placeholder state in lock screen and at add widget UI (see the image below). Otherwise when I return nil then my widget works fine. But when I try to customise widget then I don't have default values for my currencyCode field, only Chose placeholders. At the same time everything works fine for the single string parameter (without "Supports Multiple Values"). Does anybody know how to make default parameters work for array (multiple) field?

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?

Since watchOS 26, watch face sharing has stopped working completely. I tested the following: Sharing via CLKWatchFaceLibrary Other public APIs Sharing via iMessage In all cases, the watch face cannot be reinstalled after being shared. This issue is not limited to my app. Large third-party apps such as Facer and other major watch face platforms are also affected, which suggests this is a system-level change or bug. Everything worked correctly before watchOS 26. Has Apple officially acknowledged this issue? Is there a recommended place to report or track this bug?

Subject: Request to maintain the "Status Bar Breadcrumb" visibility while Dynamic Island is active Hi, I am developing an app using ActivityKit and Dynamic Island. I've noticed a significant UX regression regarding the system status bar behavior. Current Behavior: When a Live Activity is active in the Dynamic Island (specifically in the compactLeading and compactTrailing presentation), the system automatically hides the "Back to [Previous App]" breadcrumb button (the small arrow and app name) in the top-left corner of the status bar. This breadcrumb only reappears when the Live Activity switches to the minimal presentation or is dismissed. The Issue: This behavior makes multitasking cumbersome for users. For example, if a user navigates from Safari to my app and then locks the screen or goes to Home, they expect the "Back to Safari" button to remain accessible. However, because my app's Live Activity is running in the Dynamic Island, the OS removes this navigation shortcut, forcing users to use the app switcher instead. Why this should be changed: Screen Real Estate: On larger devices (e.g., iPhone 15/16 Pro Max), there is significant whitespace in the top-left corner between the time and the Dynamic Island's leading edge. The breadcrumb could easily fit there without overlapping the Live Activity content. Inconsistent UX: Users are confused why the navigation button disappears solely because a background activity is running. Request: Please consider updating the status bar layout logic to allow the "Back to App" breadcrumb to remain visible if there is no physical overlap with the compactLeading view of the Dynamic Island. Thank you.

How do I set a custom icon for an app control that appears in Control Shortcuts (swipe down from iOS) ? Where is the documentation for size and where to put the image, format etc? Thank you. Working Code (sfsymbol) import Foundation import AppIntents import SwiftUI import WidgetKit // MARK: - Open App Control @available(iOS 18.0, *) struct OpenAppControl: ControlWidget { let kind: String = "OpenAppControl" var body: some ControlWidgetConfiguration { StaticControlConfiguration(kind: kind, content: { ControlWidgetButton(action: OpenAppIntent()) { Label("Open The App", systemImage: "clock.fill") } } }) .displayName("Open The App") // This appears in the shortcuts view } } Sample Image These apps use their own image. How can I use my own image?

I want to make a app that indicates that the app is recording in the background using a indicator on the dynamic island or on the top of the phone screen but i can't figure it out on Xcode. Saw a guy do it by making live activities true but can't seem to find that option in background mode in capabilities. any ideas?

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) ) } }

I paid for the program a few days ago , how long till I’m approved?

Hello, I have tried a lot to get AlarmKit to work from a controlwidget without first going into the app. So far, I have not been successful unless I also opened the app on clicking the controlwidget. Is this a known limitation?

We are using the MPNowPlayingInfoCenter API to provide information to the “Now Playing” system UI. This works as expected, except that when the app is manually terminated, the information is removed from the UI. Our question is: Some apps (for example, Audible) are able to appear in the “Recently Played” section of the UI. This section seems to show a history of apps that previously provided “Now Playing” information but are not currently playing anything. We would like to know which API is used to achieve this behavior.

Hello, in my widget the user displays images filling the whole widget with overlayed texts (via ZStack). Via shadows or text background color the text gets better readable. However, when a user chooses transparent or tinted colors for the home screen, the text is barely or not readable anymore since e.g. white text on white image background. How to resolve this issue?

I’m manipulating some data inside a widget extension, and at the same time there is an active Live Activity (Dynamic Island / Lock Screen). How can I update the Live Activity’s local notification when the data changes? I tried accessing the current activity using Activity.activities, but it seems that this API is not accessible from inside the widget extension. What is the correct way to refresh or update the Live Activity in this case?

(I truly appreciate all the responses you all have written for me :bow: ) I was under the assumption that for Live Activity, in order for you to be able to update the Activity, you need an update token. And for the OS to issue you the update token, user must hit the "Allow" from the lock screen. However based on these screenshots it seems that you don't need to hit "Allow" to be able to update the Live Activity. Live Activity was updated — even without the user hitting "Allow" So now I'm wondering if: Is hitting Allow required for the update token to get issued? Or that assumption is incorrect? In our tests (when connected to Proxyman, the OS emits the update token after user hits "Allow" / "Always Allow") If you don't hit allow, are there alternate ways to update the Live Activity without having the update token? I'm guessing you could set a short stale time and then when the OS launches the app in the background you query the server and then update the Live Activity. Is that a worthy approach? I also noticed that the "The Philly Inquirer" App has 'Background App Refresh" enabled, but this happened in 2 minutes. In our architecture assessments, after reviewing Apple's docs on 'Background Processing", we didn't think of it as a viable option, because it can't guarantee if the OS is given time in the next 2 minutes or 10 hours later when the phone is getting charged again. Are any of these workarounds viable or are there alternate approaches? Our requirement is: be able to use Live Activity between 2-72hrs after app install. (I mention this because perhaps Apple may impost some restrictions for new installs) be able to update an active Live Activity within 1-2 minutes after it has began.
