FireBase notification not working on new installs

In my App, i'm facing an issue with push-notification. Firebase-Notification configuration is done perfectly. And working test notification which are sent from Firebase-console. Now I'm facing the issue, when the notification is fired from backend side and notification is not getting received in any of my iOS Device, where the App is fresh installed.

After terminating App if i do Logged-Out and then Re-login, then it is working fine from backend side.

    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        Messaging.messaging().apnsToken = deviceToken
        deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
        fcmTokenString = Messaging.messaging().fcmToken ?? ""

        print("deviceTokenString \(deviceTokenString)")
        print("fcmToken \(Messaging.messaging().fcmToken ?? "")")

        UIViewController().deviceToken = deviceTokenString //This will stored in UserDefault
        UIViewController().fcmToken = fcmTokenString //This will stored in UserDefault
    }

Solution

  • After go through many articles and similar questions from StackOverflow, I've get that the root cause of issue was FCM token, so I've changed the method for token fetching. And Issue has been resolved, by confirming FIRMessagingDelegate to AppDelegate.

    e.g.

    
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
     
        Messaging.messaging().delegate = self 

}

    And updated code for FCM Token fetching. Before it was getting through didRegisterForRemoteNotificationsWithDeviceToken, and updated to didReceiveRegistrationToken of FIRMessaging.

      func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        Messaging.messaging().apnsToken = deviceToken
        deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
       //fcmTokenString = Messaging.messaging().fcmToken ?? "" //Commented
        print("deviceTokenString \(deviceTokenString)")
        print("fcmToken \(Messaging.messaging().fcmToken ?? "")")
        UIViewController().deviceToken = deviceTokenString
    }

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
        guard let token = fcmToken else { return }
        print("Firebase registration token: \(token)")

        if let refreshedToken = fcmToken {
            fcmTokenString = fcmToken ?? ""
            UIViewController().fcmToken = fcmToken ?? fcmTokenString

           }

    }
