Description In Live Activities, we saw many beautiful animations that powered by .numericText() like Text(time, style: .timer), or even Text with .contentTransition(.numericText()) applied. But it seems like in normal SwiftUI View, these beautiful animations are gone. Instead, we saw a blinking result or fade-in-out result. Is that exactly right?

I used a package which contains a XCFramework inside it in my widget target. It’s working fine on iOS, and macOS Widget Simulator. But when I open widget gallery on macOS, I can’t find my widget. I tried to run my widget directly inside /Contents/PlugIns/WidgetTestExtension.appex/Contents/MacOS/WidgetTestExtension, it prints out the error: dyld[4767]: Library not loaded: @rpath/myframework.framework/Versions/A/myframework

I'm trying to copying the Colorful Confetti effect in iMessage using SwiftUI Canvas and I am wondering how to apply 3D transformation on each particle. I have tried to add a projectionTransform in order to apply a CATransform3D, but it rotates all the canvas, not a particular particle, which is not the effect I want. Currently, I use the very basic ForEach(particles.indices, id: \.self) loop to create each particle and use .rotation3DEffect to apply that transformation, but it may result in a performance issue (so, I tried to use .drawingGroup()). Is there any solutions to apply 3D transformation to a particular particle in a Canvas?? My code (using ForEach loop): GeometryReader { proxy in let size = proxy.size TimelineView(.animation) { timeline in let _: () = { let now = timeline.date.timeIntervalSinceReferenceDate model.update(at: now) }() ZStack { ForEach(model.particles.indices, id: \.self) { index in let particle = model.particles[index] particle.shape .fill(particle.color) .rotation3DEffect(.degrees(particle.degrees), axis: (x: particle.x, y: particle.y, z: particle.z)) .frame(width: particle.frame.width, height: particle.frame.height) .position(particle.frame.origin) .tag(index) } } .frame(width: size.width, height: size.height) .drawingGroup() } .contentShape(Rectangle()) .gesture( DragGesture(minimumDistance: 0) .onEnded { _ in model.loadEffect(in: size) } ) .task { model.loadEffect(in: size) } }

I created a function to add my course events to the calendar app using EventKit. After learning the swift concurrency, I want to update my code to make the progress much faster, namely using the detached task or TaskGroup to add these events. Synchronize code without detached task or task group: func export_test() { Task.detached { for i in 0...15 { print("Task \(i): Start") let courseEvent = EKEvent(eventStore: eventStore) courseEvent.title = "TEST" courseEvent.location = "TEST LOC" courseEvent.startDate = .now courseEvent.endDate = .now.addingTimeInterval(3600) courseEvent.calendar = eventStore.defaultCalendarForNewEvents courseEvent.addRecurrenceRule(EKRecurrenceRule(recurrenceWith: .daily, interval: 1, end: nil)) do { try eventStore.save(courseEvent, span: .futureEvents) } catch { print(error.localizedDescription) } print("Task \(i): Finished") } } } Doing the same thing using the TaskGroup : func export_test() { Task.detached { await withTaskGroup(of: Void.self) { group in for i in 0...15 { group.addTask { print("Task \(i): Start") let courseEvent = EKEvent(eventStore: eventStore) courseEvent.title = "TEST" courseEvent.location = "TEST LOC" courseEvent.startDate = .now courseEvent.endDate = .now.addingTimeInterval(3600) courseEvent.calendar = eventStore.defaultCalendarForNewEvents courseEvent.addRecurrenceRule(EKRecurrenceRule(recurrenceWith: .daily, interval: 1, end: nil)) do { try eventStore.save(courseEvent, span: .futureEvents) } catch { print(error.localizedDescription) } print("Task \(i): Finished") } } } } } The output of the TaskGroup version: Task 0: Start Task 1: Start Task 2: Start Task 4: Start Task 3: Start Task 5: Start Task 6: Start Task 7: Start Task 0: Finished Task 8: Start Task 1: Finished Task 9: Start Sometimes, only a few tasks will been done, and others will not, or even never been started (I created 16 tasks but only printed 9 in this example). Sometimes, all of these events can be added. In my point of view, I have created 16 child tasks in the TaskGroup. Each child task will add one event to the Calendar. I think in this way, I can take the full advantage of the multi-core performance (maybe it's actually not. 🙃) If I put the for-loop inside the group.addTask closure, it will always have the expected result, but in this way, we only have a single loop so the TaskGroup may no longer needed. I'm really exhausted🙃🙃.

Background I use AVAssetWriterInput.append to append sample buffer to the writer. Sometimes, I switch off the audio input(if user wants to temporarily disable audio input), so the append method will not be executed while the append method in video input will always be executed. Problem If user pause the audio and resume it later. The audio after resuming will immediately begin when user pause it (in the final video). Example '=' refers to CMSampleBuffer. '|' means user paused the audio input. Video: ---------------================================= Audio(expected): ----=======|----------------============= Audio(I got): ---------=======|=============---------------- I have printed the presentationTime from the audio sample buffer, it turns out it's correct. Maybe my understanding to the AVAssetWriterInput.append is wrong? My current solution is to always append the buffer, but when user wants to pause, I simply append an empty SampleBuffer filled with nothing. I don't think this is the best way to deal with it. Is there any idea to sync the buffer time with the video??

I created a screen recording app. Before appending the buffer to the writer, I check if the isReadyForMoreMediaData is true. But sometimes it will constantly return false and won’t become true until I call markAsFinished I have no idea how to fix this. let videoCompressionProperties = [     AVVideoAverageBitRateKey: resolution.dataRate ] let videoSettings: [String: Any] = [     AVVideoCodecKey:                  encoding,     AVVideoWidthKey:                  resolution.size.width,     AVVideoHeightKey:                 resolution.size.height,     AVVideoCompressionPropertiesKey:  videoCompressionProperties,     AVVideoScalingModeKey:            AVVideoScalingModeResizeAspect,     AVVideoColorPropertiesKey:        colorSpace.properties.dictionary, ] videoInput = AVAssetWriterInput(mediaType: .video, outputSettings: videoSettings) videoInput?.expectsMediaDataInRealTime = true Append buffers: if videoInput?.isReadyForMoreMediaData == true { guard buffer.imageBuffer != nil else { return } processQueue.async { [self] in videoInput?.append(buffer) } } else { logger.warning("Dropped a frame.") // I found this in stackoverflow. But no effect // RunLoop.current.run(until: .now.addingTimeInterval(0.1)) // The code below will notify me when the bug occurrs. // errorFixedPublisher.send() // if !self.errorOccured { // self.errorOccured = true // let center = UNUserNotificationCenter.current() // let content = UNMutableNotificationContent() // content.sound = UNNotificationSound.defaultCritical // content.badge = 1 // content.body = "Dropping frames at \(Date.now.formatted(date: .omitted, time: .standard))" // let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false) // let req = UNNotificationRequest(identifier: "ASWRI_ERR", content: content, trigger: trigger) // center.add(req) } } Any idea on it?? Please help me. Have a good day!

Menu {      ShareLink(...) ShareLink(...)      ShareLink(...) } label: {   Label("Share", systemImage: "square.and.arrow.up") } Here, I have different share options to choose from, and if I tap one of these share link to share sheet doesn't pop up. Is there any workaround to this issue?

In the past, I use UIApplication.shared.windows.first?.safeAreaInsets.bottom to get the bottom safe area, but in iOS 15, there is an warning shows that windows has been deprecated. My project is written in SwiftUI, so is there a way to get the global safeAreaInsets again and fits iOS 15?

App shortcuts can only be added to Shortcut Action List, but not a separate App Shortcuts appears at the bottom of the Shortcuts app. Now it only has the default Voice Memo App. It successfully appeared in beta 2/3, but I'm not sure if it appeared in (beta 3 update). But in beta 4, it disappeared. I have no idea how to make it visible again!!!

If you configure a Window and a MenuBarExtra in your app, try this: Open your app and press Command+H to hide it. Place an iPad or another Mac and connect two devices via Universal Control, and click on the other device to make your mac's menu bar inactive. Move your cursor back to your Mac(first device), and click on the whitespace of the Menu Bar. Your App is terminated unexpectedly. This behavior will only appear on those apps using Window, so to solve this issue, we may need to switch Window to WindowGroup which is not what we want. I reappear this issue on Apple's ScreenCaptureKit Sample Code. This is a SwiftUI Scene BUG, please fix this. @main struct CaptureSampleApp: App { var body: some Scene { Window("ID", id: "ID") { ContentView() .frame(minWidth: 960, minHeight: 724) .background(.black) } MenuBarExtra( "App Menu Bar Extra", systemImage: "star" ) { Text("Hello") } } } Filed a feedback: FB11447959.

If I set queueDepth to a value that smaller than 6 ( 5 for example ), the stream will be paused when I start capturing and make it minimized or hidden. Is that a correct behavior or a bug?? Filed a report: FB11441320

How to add a custom button to the Edit Menu on both iOS and iPadOS natively using SwiftUI. I have seen many ways to implement custom button using UIKit but wondering how to use SwiftUI to achieve the same thing. I have never seen any modifiers or Menus about this. I guest there is no way to do that. Any idea about this? or is it a future update for SwiftUI ??

Here is the implementation. import SwiftUI import PencilKit struct DrawingCanvas_bug: UIViewRepresentable { typealias UIViewType = PKCanvasView private let toolPicker = PKToolPicker() @Binding var drawing: PKDrawing var isOpaque: Bool = true var drawingDidChange: ((PKDrawing) -> Void)? func makeUIView(context: Context) -> PKCanvasView { let canvasView = PKCanvasView(frame: .zero) canvasView.drawing = drawing canvasView.delegate = context.coordinator canvasView.backgroundColor = .clear canvasView.isOpaque = isOpaque canvasView.alwaysBounceVertical = true // The size of the canvas is Zero, so I cannot update the ZoomScale now. // context.coordinator.updateZoomScale(for: canvasView) toolPicker.setVisible(true, forFirstResponder: canvasView) toolPicker.addObserver(canvasView) canvasView.becomeFirstResponder() return canvasView } func updateUIView(_ canvasView: PKCanvasView, context: Context) { DispatchQueue.main.async { // We can get the correct ZoomScale and the correct ContentSize, but part of the drawing is not visible. // Using the select tool can select them. context.coordinator.updateZoomScale(for: canvasView) } } func makeCoordinator() -> Coordinator { Coordinator(self) } static func dismantleUIView(_ canvasView: PKCanvasView, coordinator: Coordinator) { canvasView.resignFirstResponder() } } extension DrawingCanvas_bug { class Coordinator: NSObject, PKCanvasViewDelegate { var host: DrawingCanvas_bug init(_ host: DrawingCanvas_bug) { self.host = host } func canvasViewDrawingDidChange(_ canvasView: PKCanvasView) { host.drawing = canvasView.drawing if let action = host.drawingDidChange { action(canvasView.drawing) } updateContentSizeForDrawing(for: canvasView) } func updateZoomScale(for canvasView: PKCanvasView) { let canvasScale = canvasView.bounds.width / 768 canvasView.minimumZoomScale = canvasScale canvasView.maximumZoomScale = canvasScale canvasView.zoomScale = canvasScale updateContentSizeForDrawing(for: canvasView) } func updateContentSizeForDrawing(for canvasView: PKCanvasView) { let drawing = canvasView.drawing let contentHeight: CGFloat if !drawing.bounds.isNull { contentHeight = max(canvasView.bounds.height, (drawing.bounds.maxY + 500) * canvasView.zoomScale) } else { contentHeight = canvasView.bounds.height } canvasView.contentSize = CGSize(width: 768 * canvasView.zoomScale, height: contentHeight) } } } And here is how I use: NavigationSplitView(columnVisibility: .constant(.doubleColumn)) {     List(selection: $selection) {         ForEach(drawingModel.drawings, id: \.uuidString) {             DrawingRow(drawingData: $0)         }     } } detail: {     DrawingView() } .navigationSplitViewStyle(.balanced) // <- If I use automatic style, PKCanvasView's size is correct

How to add hosting base URL to a package(not a project)? is it possible to add an existing Swift package to my project as a target?
