Custom notification-like popup

When push notification arrives, and app is in foreground, I need to show custom popup. It must come from the upper edge of the screen, stay visible to a few seconds and then disappear back behind the top edge.

My question is how do I show it? As I know, in order to make view visible, I must add it as a subview to some existing view. But push notification may come at random time, so I do not know beforehand which view controller will be active at that moment.

So: where do I attach my custom view to (to make it visible on top of everything)?

You need to implement the following delegate in your appDelegate and your push notification will appear in foreground as well.

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    completionHandler()
}


func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler([.alert, .sound])
}

And on tapping on the notification you can get the same behavior as you do when app is in background.
