Type 'Notification.Name' (aka 'NSNotification.Name') has no member 'UIDevice'

Question

Here is my code which was working before.

NotificationCenter.default.addObserver(self, selector: #selector(ImageScrollView.changeOrientationNotification), name: Notification.Name.UIDevice.orientationDidChangeNotification, object: nil)

Answer 1

Remove Notification.Name. prefix:

NotificationCenter.default.addObserver(self, selector: #selector(ImageScrollView.changeOrientationNotification), name: UIDevice.orientationDidChangeNotification, object: nil)

The constants for notifications names were moved in iOS 12 SDK which came with Xcode 10.
