Question

There are a lot of stackoverflow threads regarding this topic, but I still didn\'t find a good solution.

If the app is not in the background, I can check launc

Answer 1

In my case, background mode OFF did not make any difference. However when the app was suspended and the user tapped the notification, I could handle the case in this callback method:

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

}
