How to differentiate between whether a notification is a local or remote notification when app Starts in IOS

Question

Previously i used the following code to differentiation whether my notification is local or remote when the app starts

    func application(_ application: UIApplication, 
    didFinishLaunchingWithOptions launchOptions: 
    [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    if (launchOptions?[UIApplication.LaunchOptionsKey.localNotification] != nil)
    {


    }
    if (launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] != nil)
    {


    }
    }

The conditions is that my app is killed and I am opening it from notification.

The problem is that this method

if (launchOptions?[UIApplication.LaunchOptionsKey.localNotification] != nil)
{


}

is deprecated and the following method isnot called when the app is opened from notification center

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

You can check the notification type in userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: too,

Class hierarchy is:

UNNotificationResponse > UNNotification > UNNotificationRequest > UNNotificationTrigger

There are 4 types of triggers in UNNotificationRequest:

• UNLocationNotificationTrigger
• UNPushNotificationTrigger
• UNTimeIntervalNotificationTrigger
• UNCalendarNotificationTrigger

Just use,

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

    if response.notification.request.trigger is UNPushNotificationTrigger {
        print("remote notification");
    }

}
