delegateClass
The class of the custom delegate object that you want UIKit to create.
Declaration
var delegateClass: AnyClass? { get set }Discussion
If you specified UIWindowScene in the sceneClass property, your delegate class must conform to the UIWindowSceneDelegate protocol. Otherwise, you must specify a class that conforms to the UISceneDelegate protocol.
UIKit sets this property’s initial value using the UISceneDelegateClassName key from the appropriate scene in your app’s Info.plist file.
