The whole "transferable" API seems pretty strange. Only some cases seem to work and no progress since last year.

If it could be bypassed, that would be a serious error. But you can always use: PHPhotoLibrary.requestAuthorization(for:handler:)

CameraView is Part of HomeKit and for surveillance cameras. Are you sure you want that? An example for using the "regular" camera APIs can be found here.

No, unfortunately not. Neither filing a Radar (FB11766691) with Feedback Assistant on 13.12.22 nor joining a session on „Ask Apple“ yielded any actionable result.

Could this be a result of App Transport Security which is active on iOS devices but not in the simulator?

Why don't you try it for yourself by using the Empty publisher? https://developer.apple.com/documentation/combine/empty

The guys from objc.io have a free video on implementing sticky headers in SwiftUI: https://talk.objc.io/episodes/S01E333-sticky-headers-for-scroll-views

@ObservedObject can only be used for objects initialized outside of the view hierarchy. Use @StateObject instead.

I don't know the reason for your error, but perhaps this very current article helps you to find it: https://www.avanderlee.com/swift/operation-couldnt-completed-error-code/

Unfortunately this is a general problem with the App Store. Only if you already once downloaded an older version of Swift Playgrounds on your account you can load this version again on older devices that don't run the current version. If you try to download an App for the first time, only the newest version will be offered and users of older devices have a problem.

In the code you posted the \ is missing from the string interpolation. Text("\(yourVar)") would be correct not Text("(yourVar)")

x and y coordinates in observation are in UnitPoints of I remember correctly. They go from 0 to 1 instead of 0 to width/height. You would have to multiply them by the width or height of the picture.

Your could observe the rate property of AVPlayer via a publisher: audioPlayer.publisher(for: .rate)

Could this be the same problem as described here?
