Доступ к камере не работает в приложении macCataylst, но в версии для iOS работает нормально [закрыто] ⇐ IOS

[Anonymous]

I am targeting iOS 17.4 and macOS 14.2 with a iOS/macCatalyst app. The app is providing a photo picker or access the camera to capture an image. My Signing and Capabilities has the following settings: App Sandbox - Hardware - Camera Hardware Runtime - Camera and Photo Library

The info.plist includes the Privacy - Camera Usage Description String - stating why the camera is required.

in my SwiftUI view controller I have the following code:

struct NewGreetingCardView: View { @State var frontImageSelected: Image? = Image("frontImage") @State var frontPhoto = false @State var sourceType: UIImagePickerController.SourceType = .photoLibrary @State var captureFrontImage: Bool = false @State private var cameraNotAuthorized = false @State private var isCameraPresented = false var body: some View { NavigationView { Form { // removed other sections for clarity Section("Image") { ZStack { frontImageSelected? .resizable() .aspectRatio(contentMode: .fit) .shadow(radius: 10 ) Image(systemName: "camera.fill") .foregroundColor(.white) .font(.largeTitle) .shadow(radius: 10) .frame(width: 150) .onTapGesture { self.frontPhoto = true } .actionSheet(isPresented: $frontPhoto) { () -> ActionSheet in ActionSheet( title: Text("Choose mode"), message: Text("Select one."), buttons: [ ActionSheet.Button.default(Text("Camera"), action: { checkCameraAuthorization() self.captureFrontImage.toggle() self.sourceType = .camera }), ActionSheet.Button.default(Text("Photo Library"), action: { self.captureFrontImage.toggle() self.sourceType = .photoLibrary }), ActionSheet.Button.cancel() ] ) } .sheet(isPresented: $captureFrontImage) { ImagePicker( sourceType: sourceType, image: $frontImageSelected) } } .frame(width: 300, height: 300) } } .onAppear(perform: { checkCameraAuthorization() }) .alert(isPresented: $cameraNotAuthorized) { Alert( title: Text("Unable to access the Camera"), message: Text("To enable access, go to Settings > Privacy > Camera and turn on Camera access for this app."), primaryButton: .default(Text("Settings")) { openSettings() } , secondaryButton: .cancel() ) } } } func openSettings() { #if os(macOS) SettingsLink { Text("Settings") } #else guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else { return } if UIApplication.shared.canOpenURL(settingsUrl) { UIApplication.shared.open(settingsUrl, completionHandler: { _ in }) } #endif } func checkCameraAuthorization() { var checkCamera: Bool checkCamera = AVCaptureDevice.authorizationStatus(for: .video) == .authorized if checkCamera == true { cameraNotAuthorized = false } else { cameraNotAuthorized = true } } } The code correctly prompts the user for authentication on iOS and macCataylst, but when I present the camera view frame, on macOS I get a blank screen, and the app crashes with the error: Thread 1: EXC_BAD_ACCESS(code=1, address=0x1c8) and a stack trace of

struct ImagePicker: UIViewControllerRepresentable { var sourceType: UIImagePickerController.SourceType = .camera @Binding var image: Image? @Environment(\.presentationMode) private var presentationMode func makeCoordinator() -> Coordinator { Coordinator(self) } func makeUIViewController(context: Context) -> UIImagePickerController { let imagePicker = UIImagePickerController() imagePicker.allowsEditing = false imagePicker.sourceType = sourceType imagePicker.delegate = context.coordinator return imagePicker } func updateUIViewController(_ uiViewController: UIImagePickerController, context: Context) { // Nothing to update here } final class Coordinator: NSObject, UINavigationControllerDelegate, UIImagePickerControllerDelegate { var parent: ImagePicker init(_ parent: ImagePicker) { self.parent = parent } func imagePickerController( _ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) { if let image = info[.originalImage] as? UIImage { parent.image = Image(uiImage: image) } parent.presentationMode.wrappedValue.dismiss() } func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { parent.presentationMode.wrappedValue.dismiss() } } }``` ===== END UPDATE ====== Are there specific things that should be looked at for Mac Catalyst. In a prior version of this app, (before macOS 14) I did nothing at all special for Mac Catalyst.
