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. We cannot reliably reproduce this issue but have collected crash logs from affected users.

Questions Is this a known issue in ViewBridge framework? Is there any workaround or mitigation we can apply from the application side? Could you provide guidance on what might trigger this condition? I have report this in Feedback Assistant FB21809243

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.

I built a couple of app intents for macOS, which generally work great. However, I'm struggling with configuring an app intent that takes a parameter, so that it doesn't require the app to launch before presenting people with the list of options. If the app is running and I run the intent in Spotlight, I can see the message defined by the intent's parameterSummary and I can select a parameter from the list of entities. If the app is not running, it is launched first and only then the intent message fully populates in Spotlight and allows parameter selection. What I've tried: Support background or deferred mode in the intent. Conformed the entities to IndexedEntity. Conformed the entity query to EnumerableEntityQuery, implementing suggestedEntities and allEntities. Conformed the entity query to EntityStringQuery. Donated the intent to Spotlight on app launch. Donated the entities to Spotlight on app launch, both using indexSearchableItems and indexAppEntities. Not sure if both are required or if the latter is just a more convenient version of the former. Do I have to conform to or implement something else? Do I need to work with an app intent extension? If so, would I put all app intent code into the extension instead of the main app? Is this a system bug I should file?

Hey, I successfully set my app to use alarm kit, alarm is showing up and everything, but I noticed that the sound I created (mp3 files, less than 30 sec each) only plays once, does not repeat itself. Is that intended?

I've created a Snippet for my iOS app which I want to be able to run from the LockScreen via a Shortcuts widget. All works fine except when I run the shortcut and the App Snippet appears, it doesn't always render the SwiftUI view in the same way. Sometimes the width boundaries are respected and sometimes not. I've tested this on iOS 26.1 and iOS 26.2 beta 3 I think this is a bug but it would be great if anyone could see what I might be doing wrong if it's not. Incase it is a bug I've filed a feedback (FB21076429) and I've created a stripped down sample project showing the issue and added screenshots showing the issue. Basic code to reproduce issue: // Intent.swift // SnippetBug import AppIntents import Foundation import SwiftUI struct SnippetEntryIntent: AppIntent { static let title: LocalizedStringResource = "Open Snippet" static let description = IntentDescription("Shows a snippet.") // Don’t open the app – stay in the snippet surface. static let openAppWhenRun: Bool = false func perform() async throws -> some ShowsSnippetIntent { .result(snippetIntent: TestSnippetIntent()) } } struct TestSnippetIntent: SnippetIntent { static let title: LocalizedStringResource = "Snippet Intent" static let description = IntentDescription("Action from snippet.") @MainActor func perform() async throws -> some IntentResult & ShowsSnippetView { .result(view: SnippetView(model: SnippetModel.shared)) } } @MainActor final class SnippetModel { static let shared = SnippetModel() private init() { } } struct SnippetView: View { let model: SnippetModel var body: some View { HStack { Text("Test Snippet with information") Spacer() Image(systemName: "heart") }.font(.headline) } } struct Shortcuts: AppShortcutsProvider { static var appShortcuts: [AppShortcut] { AppShortcut( intent: SnippetEntryIntent(), phrases: [ "Snippet for \(.applicationName)", "Test Snippet \(.applicationName)" ], shortTitle: "Snippet", systemImageName: "barcode" ) } } You also need these lines in your main App entry point: import AppIntents @main struct SnippetBugApp: App { init() { let model = SnippetModel.shared AppDependencyManager.shared.add(dependency: model) } var body: some Scene { WindowGroup { ContentView() } } } This is correct This is incorrect
