Value of type 'Messaging' has no member 'token'

I have this method to access the token (FireBaseCloudMessasing) in my VC instead of storing it in the AppDelegate but I got this error : Value of type 'Messaging' has no member 'token'

func getFCM(){
        Messaging.messaging().token { token, error in
          if let error = error {
            print("Error fetching FCM registration token: (error)")
          } else if let token = token {
            print("FCM registration token: (token)")
            self.fcmRegTokenMessage.text  = "Remote FCM registration token: (token)"
          }
        }
    }
