When using the SwiftUI declarations to define an app, where do you put the code for registering for notifications that would normally go in the app delegate?

Here is a sample code of how your App struct should look like:

Code Block swift@main
struct NewIn14App: App {
		@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
		var body: some Scene {
				WindowGroup {
						ContentView()
				}
		}
}

I put it inside applicationDidFinishLaunching as follows:

Code Block notificationCenter = UNUserNotificationCenter.current()
		notificationCenter.removeAllPendingNotificationRequests()
		let options: UNAuthorizationOptions = [.alert, .sound, .badge]
		notificationCenter.requestAuthorization(options: options) {
			(didAllow, error) in
			if !didAllow {
				print("User has declined notifications")
			}
		}
