Swift Firebase推送通知不起作用

Question

我正在我的应用程序上实现推送通知，但没有收到任何通知。

我跟踪了此视频：https://www.youtube.com/watch?v=34kvGKdPN2k

这是我在appDelegate中的代码：

    completionHandler([[.alert, .sound]])
  }

  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              didReceive response: UNNotificationResponse,

    print(userInfo)

    completionHandler()
  }
}

extension AppDelegate : MessagingDelegate {
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
      print("Firebase registration token: \(fcmToken)")

      let dataDict:[String: String] = ["token": fcmToken]
        NotificationCenter.default.post(name: Foundation.Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
      // TODO: If necessary send token to application server.
      // Note: This callback is fired at each app startup and whenever a new token is generated.
    }
    
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("message", remoteMessage.appData)
    }
}

我收到了注册令牌，但是什么也没收到。

我正在通过控制台发送通知，但没有收到通知。

我的代码有问题吗？

编辑：现在调用了消息传递委托的两种方法，但是从未调用过UNUserNotificationCenterDelegate的方法。
