Getting a warning in Swift 3 while using Push Notification with Firebase?

Question

I am using push notification service for my demo app. Using Firebase, I'm able to send the notifications to the device. But some warnings are coming in my log message. How can I remove it? And another thing, how can I get the device token here with the updated Xcode 8 in Swift 3.

Appdelegate Codes:

  import UIKit
  import Firebase
  import UserNotifications
  import FirebaseInstanceID
  import FirebaseMessaging

  @UIApplicationMain
  class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.



    UINavigationBar.appearance().barTintColor = UIColor(red: 233.0/255.0, green: 86.0/255.0, blue: 53.0/255.0, alpha: 1.0)

    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
    UIBarButtonItem.appearance().tintColor = UIColor.whiteColor()


    UITabBar.appearance().backgroundColor = UIColor.whiteColor()
    // UITabBar.appearance().tintColor = UIColor.orangeColor()
     UITabBar.appearance().tintColor = UIColor(red: 233.0/255.0, green: 86.0/255.0, blue: 53.0/255.0, alpha: 1.0)

    // [START register_for_notifications]
    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

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

    application.registerForRemoteNotifications()

First Add this Observer in didFinishLaunchingWithOptions

NSNotificationCenter.defaultCenter().addObserver(self,
                                                   selector: #selector(tokenRefreshNotification(_:)),
                                                   name: kFIRInstanceIDTokenRefreshNotification,
                                                   object: nil)

Then Add this Method in Appdelegate.M Class

func tokenRefreshNotification(notification: NSNotification) {

  let refreshedToken = FIRInstanceID.instanceID().token()
  print("InstanceID token: \(refreshedToken)")
  print("InstanceID token: \(notification.Object)")


  connectToFcm()
}

Then Check that this Method (tokenRefreshNotification)Is Called or not ?

In this method u get Token ID

Again check this =>http://stackoverflow.com/questions/37667753/ios-firebase-push-notifications-how-to-give-firebase-users-device-token-and-s/37789322#37789322 — Sanandiya Vipul, Oct 07 '16 at 04:53
