Since upgrading my phone to iOS 13 my App has ceased working. Working back through the code the problem goes away if I remove the heads up display (SKScene overlay on SCNScene).I can replicate the fault in the default 'spinning aeroplane' demo in XCode. Adding even a blank SKScene causes it to get stuck in an endless loop,let test2d = Test2D(size: CGSize(width: 100, height: 100))scnView.overlaySKScene = test2dscnView.overlaySKScene!.scaleMode = .resizeFillwith Test2D beingimport SpriteKitimport GameplayKitvar width, height : CGFloat!class Test2D: SKScene {override init (size: CGSize) { super.init(size: size) width = size.width height = size.height}required init(coder: NSCoder) { fatalError("Error")}}I cannot be the only person with this fault - anyone else able to replicate it?
