Environment iOS 17.2, Xcode 16.2, physical iPhone (12 Pro) Main app in Flutter WidgetKit extension written in Swift (Swift‑PM package) Shared App Group: group.cool.glance.shared Widget uses an AppIntent (FeedSelectionIntent) + custom entity (FeedAppEntity) Flutter bridge writes JSON snapshots for the widget Observed behaviour Flutter prints the snapshot payload and writes /…/AppGroup/<uuid>/Library/Caches/feed_snapshots.json. Widget gallery only shows the plain grey system placeholder (my sample placeholder never appears). Console log every time WidgetKit runs: chronod: Unable to resolve default intent (appintent:FeedSelectionIntent) for extension cool.glance.app.widget Error Domain=LNMetadataProviderErrorDomain Code=9000 LinkMetadata.BundleMetadataExtractionError.aggregateMetadataIsEmpty Added os_log in the widget + bridge (WidgetsBridgePlugin, FeedSnapshotStore, FeedEntityQuery, FeedSummaryTimeline), but none of them ever appear. That suggests the widget bundle can’t see the compiled AppIntent metadata or the snapshot file even though it’s there. Code (trimmed to essentials) FeedSelectionIntent.swift struct FeedSelectionIntent: AppIntent, WidgetConfigurationIntent { static var title: LocalizedStringResource = "Feed" static var description = IntentDescription("Choose which feed should appear in the widget.") @Parameter(title: "Feed", requestValueDialog: IntentDialog("Select which feed to display.")) var feed: FeedAppEntity? static var parameterSummary: some ParameterSummary { Summary("Show \(\.$feed)") } init() { feed = FeedAppEntity.sample } init(feed: FeedAppEntity?) { self.feed = feed } static var defaultValue: FeedSelectionIntent { FeedSelectionIntent(feed: .sample) } func perform() async throws -> some IntentResult { .result() } } FeedSnapshotStore.loadSnapshots() guard let containerURL = fileManager.containerURL( forSecurityApplicationGroupIdentifier: appGroupIdentifier) else { os_log("FeedSnapshotStore: missing app group container %{public}s", log: Self.log, type: .error, appGroupIdentifier) return [] } let fileURL = SharedConstants.feedSnapshotRelativePath.reduce(containerURL) { url, component in url.appendingPathComponent(component, isDirectory: component != SharedConstants.feedSnapshotFileName) } guard let data = try? Data(contentsOf: fileURL), !data.isEmpty else { os_log("FeedSnapshotStore: no snapshot data found at %{public}s", log: Self.log, type: .info, fileURL.path) return [] } // decode FeedSnapshotEnvelope… WidgetsBridgePlugin.writeSnapshots (Flutter → widget) guard let containerURL = fileManager.containerURL( forSecurityApplicationGroupIdentifier: SharedConstants.appGroupIdentifier) else { result(FlutterError(code: "container-unavailable", message: "Unable to locate shared app group container.", details: nil)) return } let targetDir = SharedConstants.feedSnapshotRelativePath.dropLast().reduce(containerURL) { $0.appendingPathComponent($1, isDirectory: true) } try fileManager.createDirectory(at: targetDir, withIntermediateDirectories: true) let targetURL = targetDir.appendingPathComponent(SharedConstants.feedSnapshotFileName, isDirectory: false) try data.write(to: targetURL, options: .atomic) WidgetCenter.shared.reloadTimelines(ofKind: "GlanceSummaryWidget") os_log("WidgetsBridgePlugin: wrote snapshots for %{public}d feeds at %{public}s", log: WidgetsBridgePlugin.log, type: .info, envelope.feeds.count, targetURL.path) Info.plist for the widget contains only: <key>NSExtensionPointIdentifier</key> <string>com.apple.widgetkit-extension</string> <key>NSExtensionAttributes</key> <dict> <key>WKAppBundleIdentifier</key> <string>cool.glance.app</string> </dict> (If I add NSExtensionPrincipalClass, the install fails with “principal class not allowed for com.apple.widgetkit-extension”, so it stays out.) What I’ve double‑checked App Group entitlement present on Runner.app and the widget extension. Snapshot file definitely exists under Library/Caches/feed_snapshots.json (size updates when Flutter writes). Code matches Apple’s “Making a configurable widget” sample (custom WidgetConfigurationIntent, entity, and timeline provider). Cleaned build folders (Flutter + Xcode), reinstalled app from scratch, but I still don’t see any of the os_log messages from the widget extension-only the LinkMetadata error above. Placeholder entry (SampleSnapshots.recentSummary) is wired up; yet the system never uses it and always drops to the generic grey preview. Questions Does LinkMetadata.BundleMetadataExtractionError.aggregateMetadataIsEmpty mean WidgetKit can’t see the compiled AppIntent metadata? If so, what could cause that when the extension is built via Swift Package Manager inside a Flutter project? Are there extra build settings or plist keys required so the AppIntent metadata gets embedded in the widget bundle? Any reason the widget would never reach my FeedSnapshotStore logs even though the file is written and the App Group is configured? Any help connecting the dots would be hugely appreciated.

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 was very excited to see the addition of push notifications for widgets. However upon further inspection, the way it is implemented seems too limiting for real life apps. I have an app for time tracking with my own backend. The app syncs with my backend in the main executable (main target). My widgets are more lightweight as they only access data in the shared app container, but they don't perform sync with the server directly to avoid race conditions with the main app. I was under the impression that the general direction of the platform is to be doing most things in the main app target (also App Intents work that way for the most part), so the fact that the WidgetPushHandler just calls the widget's method to reload the timeline is very unfortunate. In an ideal scenario I also need the main app to be 'woken up' to perform the sync with the server, and once that's done I'd update the widget's timeline and where I would just read data from the shared app container. So, my questions are: What is the recommended way of updating the widgets when this push notification arrives in the case that the main app target needs to perform the sync first? Is there any way how to detect that the method func timeline(for configuration: InteractiveTrackingWidgetConfigurationAppIntent, in context: Context) was called as a result of the push notification being received? Can I somehow schedule a background task from the widget's reloadTimeline() function? How can I get the push token later, in case that I don't save it right away the first time the WidgetPushHandler's pushTokenDidChange() is called? Thank you for your work on this and hopefully for your answers. FB19356256

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.

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?

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'm working on the control widget which should display the SF image on the UI, but I have found that it cannot be displayed stably. I have three ExampleControlWidget which is about the type egA egB and egC, it should all be showed but now they only show the text and placeholder. I'm aware of the images should be SF image and I can see them to show perfectly sometimes, but in other time it is just failed. This's really confused me, can anyone help me out? public enum ControlWidgetType: Sendable { case egA case egB case egC public var imageName: String { switch self { case .egA: return "egA" case .egB: return "egB" case .egC: return "egC" } } } struct ExampleControlWidget: ControlWidget { var body: some ControlWidgetConfiguration { AppIntentControlConfiguration( kind: kind, provider: Provider() ) { example in ControlWidgetToggle( example.name, isOn: example.state.isOn, action: ExampleControlWidgetIntent(id: example.id), valueLabel: { isOn in ExampleControlWidgetView( statusText: isOn ? Localization.on.text : Localization.off.text, bundle: bundle, widgetType: .egA //or .egB .egC ) .symbolEffect(.pulse) } ) .disabled(example.state.isDisabled) } .promptsForUserConfiguration() } } public struct ExampleControlWidgetView: View { private let statusText: String private let bundle: Bundle private var widgetType: ControlWidgetType = .egA public init(statusText: String, bundle: Bundle, widgetType: ControlWidgetType) { self.statusText = statusText self.bundle = bundle self.widgetType = widgetType } public var body: some View { Label( statusText, image: .init( name: widgetType.imageName, // the SF Symbol image id bundled in the Widget extension bundle: bundle ) ) } } This is the normal display: These are the display that do not show properly: The results has no rules at all, I have tried to completely uninstall the APP and reinstall but the result is same.

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?

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?

Using desaturated mode on an image in a widget will break any links or buttons that use the image as their 'label'. Using the following will just open the app as if there was no link at all - therefore just using the fallback userActivity handler, or any .widgetURL() urls provided. Link(destination: URL(string: "bug://never-works")!) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } The same goes for buttons: Button(intent: MyDemoIntent()) { Image("puppy") .widgetAccentedRenderingMode(.desaturated) } I've tried hacky solutions like putting the link behind the image using a ZStack, and disabling hit testing on the image, but they don't work. Anything else to try? Logged as Feedback #15152620.

In iOS 26, when using the liquid glass and the custom clear mode, the pictures of the widgets all display as gray squares and cannot show the actual images anymore. What should I do to display them?

I'm creating an app and I want the user to see the PNG image with the background removed in the widget, but I want the background to be transparent. I've seen this done before in some apps' CarPlay widgets. How can I do this?

The Widget Image display on iOS26 transparency mode is blank Both of these writing methods show blank Spaces. Is there a problem with my code or a bug in the system? The current compilation environment is Xcode Version 16.3 (16E140) iOS26.0

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?

I am looking into the new CarPlay support for systemSmall widgets introduced in iOS 26 (Apple documentation). I am trying to figure out if there is a way to programmatically detect whether the widget is currently being displayed on the iPhone/iPad home/lock screen or in CarPlay. So far, I haven’t found any information in the documentation or APIs that indicate how to distinguish between these environments. Is there an API, environment value, or best practice for handling this scenario? Thanks in advance for any insights!

Hello everyone, I am developing a Flutter iOS application that includes a Widget Extension + Live Activity (ActivityKit). The project runs successfully on the iOS simulator when launched directly from Xcode, but it cannot be signed properly via Flutter and I cannot upload the build to App Store Connect due to the following CodeSign error: Command CodeSign failed with a nonzero exit code Provisioning profile "…" doesn't include the entitlement: com.apple.developer.activitykit.allow-third-party-activity This error never goes away no matter what I try. And the main problem is that my App ID does NOT show any ActivityKit or Live Activity capability in the Apple Developer portal → Identifiers → App ID. So I cannot enable it manually. However: Xcode requires this entitlement Flutter requires this entitlement When I add the entitlement manually in the .entitlements file, Xcode says: “This entitlement must be enabled in your Developer account. It cannot be added manually.” So I am stuck in a loop where: Apple Developer portal does not show ActivityKit capability Xcode demands the ActivityKit entitlement Signing fails App Store upload fails And Live Activity is a critical feature of my app What I have already done ✔ “Automatically manage signing” is enabled ✔ Correct Team is selected for both Runner and the Widget Extension ✔ Bundle IDs are correct: com.yksbuddy.app com.yksbuddy.app.TimerWidgetExtension ✔ Deleted Derived Data completely ✔ Tried removing all ActivityKit-related entitlement keys manually ✔ Deleted Pods, reinstalled, rebuilt ✔ App Group settings match between Runner and Extension ✔ The same Live Activity code works perfectly in a clean Xcode-only project ✔ But fails only inside a Flutter project structure ✔ Xcode builds & runs on simulator, but App Store upload always fails due to missing entitlement Core Problem: In my Apple Developer “Identifiers → App ID” page, the Live Activity / ActivityKit capability does NOT appear at all, so I cannot enable: Live Activities ActivityKit Third-party activity entitlement Without being able to enable this capability, I cannot create a valid provisioning profile that includes: com.apple.developer.activitykit.allow-third-party-activity Flutter + Xcode insists this entitlement must exist, but Apple Developer portal does not give any option to enable it.

I have a SwiftUI app. It fetches records through CoreData. And I want to show some records on a widget. I understand that I need to use AppGroup to share data between an app and its associated widget. import Foundation import CoreData import CloudKit class DataManager { static let instance = DataManager() let container: NSPersistentContainer let context: NSManagedObjectContext init() { container = NSPersistentCloudKitContainer(name: "DataMama") container.persistentStoreDescriptions = [NSPersistentStoreDescription(url: FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: group identifier)!.appendingPathComponent("Trash.sqlite"))] container.loadPersistentStores(completionHandler: { (description, error) in if let error = error as NSError? { print("Unresolved error \(error), \(error.userInfo)") } }) context = container.viewContext context.automaticallyMergesChangesFromParent = true context.mergePolicy = NSMergePolicy(merge: .mergeByPropertyObjectTrumpMergePolicyType) } func save() { do { try container.viewContext.save() print("Saved successfully") } catch { print("Error in saving data: \(error.localizedDescription)") } } } // ViewModel // import Foundation import CoreData import WidgetKit class ViewModel: ObservableObject { let manager = DataManager() @Published var records: [Little] = [] init() { fetchRecords() } func fetchRecords() { let request = NSFetchRequest<Little>(entityName: "Little") do { records = try manager.context.fetch(request) records.sort { lhs, rhs in lhs.trashDate! < rhs.trashDate! } } catch { print("Fetch error for DataManager: \(error.localizedDescription)") } WidgetCenter.shared.reloadAllTimelines() } } So I have a view model that fetches data for the app as shown above. Now, my question is how should my widget get data from CoreData? Should the widget get data from CoreData through DataManager? I have read some questions here and also read some articles around the world. This article ( https://dev.classmethod.jp/articles/widget-coredate-introduction/ ) suggests that you let the Widget struct access CoreData through DataManager. If that's a correct fashion, how should the getTimeline function in the TimelineProvider struct get data? This question also suggests the same. Thank you for your reading my question.

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?

Hi everyone, I am encountering an issue where my Live Activity (Dynamic Island) suddenly became invalid and failed to launch. It was working perfectly before, and I haven't modified any code since then. My Environment: Xcode: 26.1.1 Device iOS: 26.1 Testing: I also tested on iOS 18, but the Live Activity fails to start there as well. Here is my code: Live Activity Manager (Start/Update/End): func startLiveActivity() { // Initial static data let attributes = SimpleIslandAttributes(name: "Test Order") // Initial dynamic data let initialContentState = SimpleIslandState(message: "Preparing...") // Adapting for iOS 16.2+ new API (Content) let activityContent = ActivityContent(state: initialContentState, staleDate: nil) do { let activity = try Activity.request( attributes: attributes, content: activityContent, pushType: nil // Set to nil as remote push updates are not needed ) print("Live Activity Started ID: \(activity.id)") } catch { print("Failed to start: \(error.localizedDescription)") } } // 2. Update Live Activity func updateLiveActivity() { Task { let updatedState = SimpleIslandState(message: "Delivering 🚀") let updatedContent = ActivityContent(state: updatedState, staleDate: nil) // Iterate through all active Activities and update them for activity in Activity<SimpleIslandAttributes>.activities { await activity.update(updatedContent) print("Update") } } } // 3. End Live Activity func endLiveActivity() { Task { let finalState = SimpleIslandState(message: "Delivered ✅") let finalContent = ActivityContent(state: finalState, staleDate: nil) for activity in Activity<SimpleIslandAttributes>.activities { // dismissalPolicy: .default (immediate), .after(...) (delayed), .immediate (no animation) await activity.end(finalContent, dismissalPolicy: .default) print("End") } } } The Models (Shared between App and Widget Extension): // 1. Define State (Dynamic data, changes over time, e.g., remaining delivery time) public struct SimpleIslandState: Codable, Hashable { var message: String } // 2. Define Attributes (Static data, constant after start, e.g., Order ID) public struct SimpleIslandAttributes: ActivityAttributes { public typealias ContentState = SimpleIslandState var name: String // e.g., "My Order" } The Widget Code: // // SimpleIslandWidget.swift // ReadyGo // // Created by Tang Yu on 2025/11/19. // import WidgetKit import SwiftUI import ActivityKit struct SimpleIslandWidget: Widget { var body: some WidgetConfiguration { ActivityConfiguration(for: SimpleIslandAttributes.self) { context in // UI shown on the Lock Screen VStack { Text("Lock Screen Notification: \(context.state.message)") } .activityBackgroundTint(Color.cyan) .activitySystemActionForegroundColor(Color.black) } dynamicIsland: { context in // Inside Widget Extension DynamicIsland { // Expanded Region DynamicIslandExpandedRegion(.center) { Text("Test") // Pure text only } } compactLeading: { Text("L") // Pure text only } compactTrailing: { Text("R") // Pure text only } minimal: { Text("M") // Pure text only } } } } Additional Info: This is the minimal code setup I created for testing, but even this basic version is failing. I have set NSSupportsLiveActivities (Supports Live Activities) to YES (true) in the Info.plist for both the Main App and the Widget Extension. Has anyone experienced this? Any help would be appreciated.

Hi, I'm working on an app that integrates third-party UWB accessories using the Nearby Interaction framework. I want to display real-time data via Live Activities, and ideally, I hope the app can continue ranging/interacting with the accessory even when it's in the background—triggering updates in the Live Activity. Specifically: Can I use Live Activity to keep Nearby Interaction sessions running in the background, as long as the accessory is still nearby and connected? Or do I always need to initiate sessions in the foreground? Are there ways to maintain or trigger new Nearby Interaction sessions entirely in the background, when using third-party UWB accessories? Is there any official guidance regarding permissions, user authorization requirements, or restrictions for background ranging with third-party hardware? Are there recommended strategies or patterns for updating Live Activity widgets with data from Nearby Interaction or UWB accessories while backgrounded? (e.g. Bluetooth triggers, push notifications, background tasks) Any advice, experiences, or official recommendations would be greatly appreciated! I want to ensure my implementation is compliant and offers the best possible user experience. Thanks!
