Question

I am working with Xcode 8.1 & swift 2.3 here I am using firebase integration for getting push notifications.I don't know why i am not getting notifications.. My code:

     func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


            if #available(iOS 10.0, *) {
                let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound]
                UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
                    authOptions,
                    completionHandler: {_,_ in })

                // For iOS 10 display notification (sent via APNS)
                UNUserNotificationCenter.currentNotificationCenter().delegate = self
                // For iOS 10 data message (sent via FCM)
                FIRMessaging.messaging().remoteMessageDelegate = self
                 application.registerForRemoteNotifications()

            } else
            {
                let settings: UIUserNotificationSettings =
                    UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
                application.registerUserNotificationSettings(settings)
            }

            application.registerForRemoteNotifications()
            FIRApp.configure()

            // Add observer for InstanceID token refresh callback.
            if #available(iOS 10.0, *) {
                NSNotificationCenter.defaultCenter().addObserver(self,
                                                                 selector: #selector(self.tokenRefreshNotification),
                                                                 name: kFIRInstanceIDTokenRefreshNotification,
                                                                 object: nil)
            } else {
                // Fallback on earlier versions
            }
    return true
    }

  func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                     fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

        FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}

 func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings)
    {
        application.registerForRemoteNotifications()


    }

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
    {
        print(deviceToken)
        let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
        var tokenString = ""

        for i in 0..<deviceToken.length {
            tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
        }

        //Tricky line
        FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
        print("Device Token:", tokenString)

    }
    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        // Print the error to console (you should alert the user that registration failed)
        print("APNs registration failed: (error)")
    }

    @available(iOS 10.0, *)
    func tokenRefreshNotification(notification: UNUserNotificationCenter) {
        if let refreshedToken = FIRInstanceID.instanceID().token() {
            print("InstanceID token: (refreshedToken)")
            let deviceFCMToken: String = refreshedToken
            NSUserDefaults.standardUserDefaults().setObject(deviceFCMToken, forKey: "FCMToken")
            NSUserDefaults.standardUserDefaults().setBool(true, forKey: "isFCMTokenAvailable")
             //UIApplication.sharedApplication().registerForRemoteNotifications()
        }

        // Connect to FCM since connection may have failed when attempted before having a token.
        connectToFcm()
    }
    func connectToFcm()
    {
        FIRMessaging.messaging().connectWithCompletion { (error) in
            if (error != nil)
            {
                print("Unable to connect with FCM. (error)")
            } else {
                print("Connected to FCM.")
            }
        }
    }


extension AppDelegate : FIRMessagingDelegate
{
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage)
    {

        print("%@", remoteMessage.appData)
    }
}
