Getting FCM key nil from Firebase cloud messaging - swift

Question

Am trying to fetch FCM key for push notification from Firebase cloud messaging but am getting nil & error which i mention below
**
Error :- APNS device token not set before retrieving FCM Token for Sender ID '836092823410'. Notifications to this FCM Token will not be delivered over APNS.Be sure to re-retrieve the FCM token once the APNS device token is set.
