Firebase push notifications swift 3

Asked by At

So I'm trying to implement push notifications to my app using Firebase, the problem is that the push comes and I receive this message :

[AnyHashable("id_entity"): 18, AnyHashable("icon"): , AnyHashable("click_action"): offer, AnyHashable("body"): test by almotech, AnyHashable("from"): 1054934643579, AnyHashable("title"): Test Push Notification, AnyHashable("subject"): offer]

But it does not come on the iPhone, nothing shows up not on background neither on foreground, nothing at all. Any help?

Below is the code I've used:

var window: UIWindow?
 let gcmMessageIDKey = "gcm.message_id"
 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    //UITabBar.appearance().tintColor = myGreenColor
    UINavigationBar.appearance().barTintColor = myGreenColor
    UINavigationBar.appearance().tintColor = UIColor.white
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]
    UIApplication.shared.statusBarStyle = .lightContent
    //UP Screen when keyboard appear.
    IQKeyboardManager.sharedManager().enable = true
    // Override point for customization after application launch.

    //MARK:-Push Notifications
    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
        //application.registerForRemoteNotifications()
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        //application.registerForRemoteNotifications()
    }
    application.registerForRemoteNotifications()

    // [END register_for_notifications]
