PencilKitCanvas cannot becomeFirstResponder in SwiftUI
I have done the same thing in SwiftUI using UIViewRepresentable, but toolPicker doesn't show so I checked isFirstResponder property and I found that it was still false after I called canvas.becomeFirstResponder(). Check this out: struct NoteCanvasView: UIViewRepresentable {     func makeUIView(context: Context) -> PKCanvasView {         let canvas = PKCanvasView()         canvas.drawingPolicy = .anyInput         canvas.delegate = context.coordinator.self                  let toolPicker = PKToolPicker()         toolPicker.setVisible(true, forFirstResponder: canvas)         toolPicker.addObserver(canvas)         print(canvas.canBecomeFirstResponder)         canvas.becomeFirstResponder()         print(canvas.isFirstResponder)         return canvas     }          func updateUIView(_ canvas: PKCanvasView, context: Context) {         canvas.becomeFirstResponder()     }          func makeCoordinator() -> Coordinator {         Coordinator(self)     }          class Coordinator: NSObject {         var parent: NoteCanvasView         init(_ parent: NoteCanvasView) {             self.parent = parent         }     } } I found canvas.canBecomeFirstResponder returns true and canvas.isFirstResponder always returns false. Is this a bug in current version of SwiftUI??

App Terminates when using Window and MenuBarExtra in SwiftUI
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.

SwiftUI Canvas with 3D Transformation
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) } }

Cannot see my widget in Widget Gallery (macOS)
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
