WidgetKit: WidgetCenter.reloadAllTimelines() / reloadTimelines(ofKind:) requests are silently ignored/deferred, causing widget to remain unupdated UI Frameworks SwiftUI
Problem After launching the host app by tapping the widget (widgetURL), calls to: WidgetCenter.shared.reloadAllTimelines() WidgetCenter.shared.reloadTimelines(ofKind: ...) are ignored/deferred for an initial period right after the app opens. During this window, the widget does not reload its timeline and remains unupdated, no matter how many times I call the reload methods. After some time passes (typically ~30 seconds, sometimes shorter/longer), reload calls start working again. There is also no developer-visible signal (no callback/error/acknowledgement) that the reload was ignored, so the app can’t detect the failure and can’t reliably recover the flow. Question: Is this expected behavior (throttling/cooldown) after opening the app from a widget ? If so, is there any recommended workaround to update the widget reliably and quickly (or at least detect that the reload was not accepted)? Any guidance would help.

ControlWidgetToggle image design
I need help designing the image of a ControlWidgetToggle. do I understand correctly that I can only use an SFSymbol as image and not my custom image (unless setup via a custom SFSymbol)? is there any way I can influence the size of the image? I tried multiple SwiftUI modifiers (.imageScale, .font, .resizable, .controlSize) none of them seem to work. My image remains too tiny the image size of the on and off state is different. Seems to be enforced by the system. Is there any way to make both images use the same size? the on-state tints the image. Is there a way to set the tint color? .tint and .foregroundstyle seem to be ignored. Thank you for your help

Lock Screen Quick Action Fails to Present CameraCaptureIntent View After Main App Transition
I am encountering an issue where the Lock Screen Quick Action fails to visibly open my app. My app is a camera application that utilizes a CameraCaptureIntent to launch a standalone, lightweight camera view (accessible while the device is locked), distinct from the main application. Steps to Reproduce: Open the lightweight camera view using the Lock Screen Quick Action. From this view, launch the Main App. Lock the iPhone (put it to sleep). Attempt to launch the lightweight camera view via the Quick Action again. A slight animation occurs, but the camera view does not appear on screen. After multiple tests, it seems the view is actually launching but remains in an "invisible state." I suspect that the system hides the lightweight camera view when transitioning to the Main App, but fails to reset this hidden state when the Quick Action is triggered subsequently. I would appreciate any guidance on a potential workaround or confirmation if this is a known issue awaiting a system update.

Control Center widget won't show snippet view
Has anyone been able to create a Control Center widget that opens a snippet view? There are stock Control Center widgets that do this, but I haven't been able to get it to work. Here's what I tried: struct SnippetButton: ControlWidget { var body: some ControlWidgetConfiguration { StaticControlConfiguration( kind: "xxx.xxx.snippetWidget" ) { ControlWidgetButton(action: SnippetIntent()) { Label("Show Snippet", systemImage: "map.fill") } } .displayName(LocalizedStringResource("Show Snippet")) .description("Show a snippet.") } } struct SnippetIntent: ControlConfigurationIntent { static var title: LocalizedStringResource = "Show a snippet" static var description = IntentDescription("Show a snippet with some text.") @MainActor func perform() async throws -> some IntentResult & ProvidesDialog & ShowsSnippetView { return .result(dialog: IntentDialog("Hello!"), view: SnippetView()) } } struct SnippetView: View { var body: some View { Text("Hello!") } }

WidgetKit (systemMedium) SwiftUI Text: auto-fit to the largest font size without “…”
Hi all, I’m stuck on a WidgetKit/SwiftUI layout issue. I have a systemMedium widget that shows a block of text. What I want is simple: The text should be as large as possible But it must always fully fit inside the widget No ellipsis (“…”) Short text → big font Longer text → shrink only as much as needed The problem: when I try to make the font larger, the widget often shows only a couple of words and then “…” (or it looks like it’s truncating/clipping), even though I’m using multiline text (lineLimit(nil) etc.). If I keep a small fixed font size, the entire text shows fine — so the input string isn’t truncated. I tried a few approaches: ViewThatFits seeing which font size fits minimumScaleFactor Measuring with NSAttributedString.boundingRect + binary search to calculate the biggest font size that should fit But WidgetKit still behaves inconsistently and I can’t get a reliable “largest size that fits” result. Is there a recommended, production-safe way to do this in WidgetKit? Also: can a SwiftUI Text still end up showing “…” in a widget even with .lineLimit(nil) when it’s constrained vertically? Thanks in advance — any pointers or known patterns would really help.

WidgetKit + AppIntent widget never sees shared snapshots (Flutter host app)
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.

Contrast for texts in widgets with image backgrounds transparent mode
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?

New push notifications for widgets seem too limited for actual production-level apps
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

Watch Face sharing stopped working on watchOS 26 (CLKWatchFaceLibrary)
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?

Нow to set default values for string array intent field provided dynamically?
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?

Control Widget SF image cannot stably display
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.

How To Set Custom Icon for Control Center Shortcuts
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?

Widget link broken by `.desaturated` image rendering mode
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.
