iOS16 can only set wallpaper from shortcuts with legacy lock screen wallpaper(The first lock screen when long press to edit the lock screen). But I deleted the legacy lock screen and cannot bring it back. So shortcuts set wallpaper not working any more. This issue comes from iOS16 beta 1,2,3,4 The only way I think is to downgrade to iOS15(get the legacy lock screen) and update to beta version again. Is there any better way to solve it?

let note = UITextView(frame: self.view.frame) self.view.addSubview(note) var text = "" for i in 0..<3000{      text.append("\(i + 1)")     text.append("\n") } note.text = text The code is really simple, when it runs on iOS14, it works fine. But when runs on iOS15 device, just scroll few times(eg: 351 lines), and tap the textView, it will scroll to 648 lines. I don't know if it is a new feature or a bug on iOS15. Test on: Xcode 13.0 beta3 and Xcode 12.5.1, iPhone XR (iOS15.0 beta3)

I would like to train a model for object detection. When the training iteration reached to the maximum I set, Create ML app is still in training process and I don't see any trained model. I tested on both Xcode 11.5 and Xcode 12.0 beta built in Create ML app. The issue is still exist. So just for testing, I set the maximum iteration to 20, no model find when reached to 20 iterations. Anyone has a solution?
