What is the @UIApplicationDelegateAdaptor property wrapper?
Updated for Xcode 12.0
New in iOS 14
If you need to get access to AppDelegate functionality in SwiftUI, you should create a class that inherits from NSObject and UIApplicationDelegate, and give it any functionality you want, such as this:
class AppDelegate: NSObject, UIApplicationDelegate {
// add app delegate methods here
}Once you have that, use the UIApplicationDelegateAdaptor property wrapper in your main App so that SwiftUI knows to create and manage your app delegate class:
@main
struct NewIn14App: App {
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
