Firebase (FCM) Не удалось получить токен APNS Ошибка домена = com.firebase.iid Код = 1001

Я пытаюсь использовать FCM для уведомления.
Но <FIRInstanceID/WARNING> Не удалось получить токен APNS Ошибка Domain=com.firebase.iid Code=1001 "(null)", поэтому я не могу получить уведомление. В чем проблема?

На консоли,
  Не удалось получить токен APNS Error Domain=com.firebase.iid Code=1001 "(null)"

и ниже мой код на Appdelegate

• Я могу получить уведомление от консоли Firebase, если я отправляю уведомления с помощью идентификатора пакета. Но я не могу получить, если наш сервер отправит уведомление конкретному устройству с токеном.

func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
    // Send the token to your server here
}

let token = Messaging.messaging().fcmToken  // Send this to your server
