iOS do not call didReceiveRemoteNotification or didReceive events when receives a message

[Flavio]

Hi, I know that this topic was posted thousands of times by other users. I know this bacause I read all of those posts. ;-)

But until now I don't know why my app does not get notified when the phone receives a message.

I can tell that the messages arrives because I can see it on Firebase debug log as you can see below:

%@ [AnyHashable("notification"): {

    body = "Server Test";

    e = 1;

    sound = default;

    sound2 = default;

    title = Test;

}, AnyHashable("from"): 863402413932, AnyHashable("message"): Notification from Java application, AnyHashable("collapse_key"): com.itrax.VanCool]

I tried send messages via my server and via Firebase Console and I get the same result. Does not matter if the app is in foreground or background mode, I got nothing.

I'm testing on iOS Simulator running iOS 10.1, XCode 8 and Swift 3

Here is Swift my code

        func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

               

        FIRApp.configure()

        initFirebade(application: application)

        

        return true

    }

    func initFirebade(application: UIApplication){

        if #available(iOS 10.0, *) {

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]

            UNUserNotificationCenter.current().requestAuthorization(

                options: authOptions,

                completionHandler: {_, _ in })

            

            // For iOS 10 display notification (sent via APNS)

            UNUserNotificationCenter.current().delegate = self

            // For iOS 10 data message (sent via FCM)

            FIRMessaging.messaging().remoteMessageDelegate = self

            

        } else {

            let settings: UIUserNotificationSettings =

                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)

            application.registerUserNotificationSettings(settings)

        }

        

        application.registerForRemoteNotifications()

        

        NotificationCenter.default.addObserver(self,

                                               selector: #selector(self.tokenRefreshNotification),

                                               name: NSNotification.Name.firInstanceIDTokenRefresh,

                                               object: nil)

 

        connectToFcm()

        

    }

    

    

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

        

        

        // set firebase apns token

        FIRInstanceID.instanceID().setAPNSToken(deviceToken as Data, type: FIRInstanceIDAPNSTokenType.sandbox)

    }

    func tokenRefreshNotification(_ notification: Notification) {

        if let refreshedToken = FIRInstanceID.instanceID().token() {

            print("InstanceID token: \(refreshedToken)")

            Utils.setFirebaseToken(firebaseToken: refreshedToken)

            FIRMessaging.messaging().subscribe(toTopic: "/topics/ledices")

        }

        

        // Connect to FCM since connection may have failed when attempted before having a token.

        connectToFcm()

    }

    func connectToFcm() {

        FIRMessaging.messaging().connect { (error) in

            if error != nil {

                print("Firebase Unable to connect with FCM. \(error)")

            } else {

                print("Firebase Connected to FCM.")

                FIRMessaging.messaging().subscribe(toTopic: "/topics/ledices")

            }

        }

    }

    func application(_ application: UIApplication, didReceive notification: UILocalNotification) {

        print("Firebase message 1")

        print(notification)

    }

    

 

  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {

        print("Firebase message 2")

    }

    

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

        print("Firebase message 3")

    }

    func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {

        print("Firebase register settings")

    }

    

    func application(_ application: UIApplication, performFetchWithCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

        print("Firebase background fetch")

    }

Here is my Java code for the server:

public static void sendMessage(String destinatary,String stMessage) throws IOException{

FCMSender sender=new FCMSender(SERVER_KEY);

Notification notification = new Notification.Builder(null)

.body("Server Test")

.title("Test").build();

Message message = new Message.Builder()

                .collapseKey("message")

                .timeToLive(60)

                

                //.delayWhileIdle(true)

                .priority(Priority.HIGH)

                .addData("message", "Notification from Java application")

                .notification(notification)

                .build();

                

// Use the same token(or registration id) that was earlier

// used to send the message to the client directly from

// Firebase Console's Notification tab.

System.out.println(destinatary);

Result result = sender.send(message,destinatary,5);

        System.out.println("Error: "+result.getErrorCodeName());

System.out.println("Success: "+result.getSuccess());

System.out.println("Message Id: "+result.getMessageId());

}

As I said I'd test sending message via Firebase Console and Server and I got nothing. I get no notifications when the app is foreground and background.

Here is my Xcode capabilities

I appreciate any help. I'm about to give up Firebase because I'm almost one week on this integration process and I have advanced very little. I thnk that Firebase should review its tutorial regarding iOS integration. It is deprecated and results on a non funcitional code. If I'd advance something is because of information that I got from posts of other pragrammers not Firebase documentation.

Thank you very much.

Skimming the code it looks like: 

* applicationReceivedRemoteMessage is missing

* FIRMessaging.messaging.setRemoteMessageDelegate is missing

For a data message on an iOS 10 deploy target, thats the method you need.

notification not work on Simulator  , try in real device .
