The animation requires the cell to be scrolled off-screen and back into view to render correctly.

After upgrading to watchOS 26, users report that when playing music on Apple Watch, if a fitness reminder is received, the music automatically pauses and users need to manually tap the play button to resume music playback. This phenomenon occurs with multiple music and podcast apps. This issue did not exist before the upgrade. We would like to know if this is an Apple bug or if there are any special development configurations needed?"

Widget abnormal refresh My app is a music application. When playing or pausing a song, the status is synchronized to NowPlaying, and the app itself supports widgets. During testing, I found that when pausing or playing music, the widget triggers a timeline refresh, which is completely unexpected. However, switching songs does not cause this.

I want to ask if this is the system’s mechanism? I checked my code and there is no operation to actively refresh the widget when pausing or playing. Can this situation be avoided?

previously, setting accessoryImage would display the image on the far right. Now, it appears right next to the detailText, and the image is extremely small. I am already using the latest beta, but the problem still exists.

Some users have reported that the app's widgets have disappeared after we updated to the latest Xcode for iOS 18 development. They are unable to find our app in the widget search, which prevents them from re-adding the widget. We were unable to reproduce this issue on our own devices during testing. Could this be a system bug? Have others encountered a similar issue?

here is my case: i add the AppIntent to both your app and widget extension targets. the intent will run my app process when app is running. it works perfectly on iOS 17. but iOS 18, my app process never called. i download app's demo, https://developer.apple.com/documentation/widgetkit/emoji-rangers-supporting-live-activities-interactivity-and-animations it looks like the same issue. it runs well because even it runs in the widget extension target, it still can present expected UI. but in real case, we need to run the app process to do some work. by debugging, i found the app process never called（set breakpoint）. i add openAppWhenRun, it works well on iOS 18. but it will open the app when the widget is running. it is not what i want.

Objective: When the app is running, directly operate the app without launching it. When the app is not started, wake up the app to perform the corresponding operation. Premise: AppIntent's openAppWhenRun can dynamically control whether the app is launched, but the variable itself cannot be changed. Therefore, the idea is to refresh the widget when the app is started or terminated, displaying different content (binding different intents) to achieve the goal. However, there are persistent issues during code implementation. struct ControlWidgetContent: ControlWidgetTemplate { var body: some ControlWidgetTemplate { if (applaunched) { return ControlWidgetButton(action: Aintent()) { Label("xxxx", systemImage: "calendar") } } else { return ControlWidgetButton(action: Bintent()) { Label("xxxx", systemImage: "calendar") } } } } @available(iOS 18.0, *) struct ControlWidgetContent: ControlWidget { let kind: String = "ControlWidgetInterface" var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind: kind ) { ControlWidgetContent() }.displayName("xxxx") } } it preports error: Function declares an opaque return type 'some ControlWidgetTemplate', but the return statements in its body do not have matching underlying types Return statement has underlying type 'ControlWidgetButton<Label<Text, Image>, ControlWidgetButtonDefaultActionLabel, PlayDayRcmdIntent>'

In a music streaming app, when using Activity.request to activate the Dynamic Island, the system’s Now Playing interface appears correctly. However, the app's live activities, lock screen, and other related features fail to display properly. During debugging, the following code is used: activity = try Activity.request(attributes: attributes, contentState: contentState, pushType: .token) if !NMABTestManager.default().is(inTest: "FH-NewLiveActivityPush") { // Listen to push token updates if activity != nil { tokenUpdatesTask?.cancel() tokenUpdatesTask = Task.detached { for await tokenData in self.activity!.pushTokenUpdates { let mytoken = tokenData.map { String(format: "%02x", $0) }.joined().uppercased() // pushToken is Data, needs to be converted to String using the above method before being passed to the server self.pushToken = mytoken } } } } } catch (let error) { print("Error Starting Live Activity: \(error.localizedDescription)") } In this scenario, the push token is returned correctly, and no errors are triggered. This issue did not occur in iOS 17 but appears sporadically in iOS 18. Once it occurs, it cannot be resolved through restarting or other means. feedbackid：FB14763873, i upload my sysdisagnose

here's my case, i develop a control widget, user can push a controlwidget to play music without open the app. i bind a AudioPlaybackIntent to the widget. when user click the widget, the app will receive the intent and start to play music. it works perfect when app running in background or foreground. but when app not launched, the respond is too slow, it takes several seconds to start play music. is there any way to make the respond faster when app not launched? if i want to do something when app not launched, what should i do?

i export apple SF as custom sf for test. code is simple: var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind:"ControlWidgetConfiguration" ) { ControlWidgetButton(action: DynamicWidgetIntent()) { Text("test") Image("custom_like") } }.displayName("test") } as we can see, it can't show image in the preview. but it can show image in the Control widget center. am i do some thing wrong?

i init a CPAlertTemplate with a CPAlertAction, on iOS17, action can called by button click, but on iOS18, action can not be called by button click. so i can't dissmiss the alert by button click.

i'm struct dynamic island detail content dynamicIsland: { context in DynamicIsland { expandedContent(context: context) } compactLeading: { .... } compactTrailing: { ... } i want show different content based on context. private func expandedContent(context: ActivityViewContext<xxxx>)->DynamicIslandExpandedContent<some View> { if (context.state.style == 0) { return expandedControlContent1(context: context) } else if (context.state.style == 1) { return expandedControlContent2(context: context) } else { return expandedControlContent3(context: context) } } compiles error Function declares an opaque return type 'some View', but the return statements in its body do not have matching underlying types
