How do I get the keyWindow reference in a swift app?

Question

In Objective-C in the viewDidLoad method of a UIViewController I do this to get the keyWindow reference in my iOS app:

 UIWindow * keyWindow = [[UIApplication sh         


        

Answer 1

For Swift 5:

var keyWindow: UIWindow? {
    return UIApplication.shared.connectedScenes.filter({$0.activationState == .foregroundActive}).map({$0 as? UIWindowScene}).compactMap({$0}).first?.windows.filter({$0.isKeyWindow}).first
}
