问题 I have a problem getting the current UIScene when multiple scenes are connected. Specifically, my app (iOS 13) supports multiple windows on the iPad.

I'm using Core Data with Cloud Kit, and have therefore to check the iCloud user status during application startup. In case of problems I want to issue a dialog to the user, and I do it using UIApplication.shared.keyWindow?.rootViewController?.present(...) up to now.

This is my solution: let keyWindow = UIApplication.shared
