iOS- FCM 未收到推送通知

Question

我是Firebase云消息传递的新手，以下是我使用的相关代码。当我尝试从 Firebase 通知编辑器发送推送通知时，尽管消息状态为已完成。我的客户端中未收到任何消息。我错过了什么吗？我的用例需要将消息从一个应用程序发送到另一个具有不同捆绑 ID 的应用程序。您将推荐哪种应用程序服务器？

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {Messaging.messaging().delegate = self
        if #available(iOS 10.0, *) {
            // For iOS 10 display notification (sent via APNS)
            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()
        FirebaseApp.configure()
    }
     // [START receive_message]
     func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
         Messaging.messaging().appDidReceiveMessage(userInfo)

您需要设置 Firebase 消息委托

Messaging.messaging().delegate = self
