I knew this and still came here for answers as I had forgot. So just a polite reminder. The calls will not be made in the simulator. Ensure to be on real device :-)

I using the following function it is working fine 

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        if let refreshedToken = InstanceID.instanceID().token() {
           print("InstanceID token: \(refreshedToken)")
        }
    }

 didReceiveRegistrationToken

is a delegate function. it will get called upon receiving token form firebase. if it's not getting called make sure you've following code in AppDelegate

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

with Messaging.messaging().delegate = self we are registering AppDelegate for receiving the method call from Firebase
