For iOS 10 and above put this in AppDelegate, to get to know notification is tapped(works even app is closed or open)

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