Firebase CloudMessaging不工作Swift 5

我正在我的项目中实施Firebase云消息传递解决方案。我遵循了所有要求的步骤，但在从Firebase控制台发送测试消息或发布新消息时，我仍然没有收到任何通知

这是我的密码：

import UIKit
import FirebaseCore
import FirebaseMessaging
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    // Variables
    var window: UIWindow?
    let gcmMessageIDKey = "gcm.message_id"
    
    // Functions
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        FirebaseApp.configure()
        FirebaseAuth.login(email: FirebaseAuth.adminUser.email, password: FirebaseAuth.adminUser.password) {
            (userAuthenticaed) in
            if userAuthenticaed
            {
                FirebaseDatabase.initDatabase()
                FirebaseStorage.initStorage()
                
                FirebaseDatabase.getContactDetails()
                FirebaseDatabase.getInventory()
                
                FirebaseAuth.logout()
                FirebaseAuth.user = nil
            }
        }

        Messaging.messaging().delegate = self
        self.registerForPushNotifications(application: application)
        
        return true
    }
    
    func registerForPushNotifications(application: UIApplication) {
        if #available(iOS 10.0, *) {
            UNUserNotificationCenter.current().delegate = self

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()
    }
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }
        
        print(userInfo)
    }
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }
        
        print(userInfo)
        
        completionHandler(UIBackgroundFetchResult.newData)
    }
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Unable to register for remote notifications: \(error.localizedDescription)")
    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("APNs token retrieved: \(deviceToken)")
    }
}

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }
        
        print(userInfo)
        
        completionHandler([[.alert, .badge, .sound]])
    }
}

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: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)

        print(fcmToken)
    }
}

我从“功能”菜单启用了推送通知和远程通知

我生成了一个Auth APNs密钥，并将其上传到Firebase控制台中的项目中

我的资源调配配置文件包括推送通知

我确实看到调用了

didRegisterForRemoteNotificationsWithDeviceToken

和

didReceiverRegistrationToken

，因此注册成功，但是没有消息到达

我错过了什么
