CloudKit 订阅不起作用

Question

我正在尝试使用 CloudKit 和 Swift 订阅推送通知。这是我的代码：

应用委托：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    //Push
    let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()
    if let options: NSDictionary = launchOptions {
        let remoteNotification = options.objectForKey(UIApplicationLaunchOptionsRemoteNotificationKey) as? NSDictionary
        if let notification = remoteNotification {
            self.application(application, didReceiveRemoteNotification: notification as! [NSObject : AnyObject])
        }
    }

    return true

}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    let ckNotification = CKNotification(fromRemoteNotificationDictionary: userInfo as! [String : NSObject])
    if ckNotification.notificationType == .Query {
        let queryNotification = ckNotification as! CKQueryNotification
        let recordID = queryNotification.recordID
        let container = CKContainer.defaultContainer()
        let privateDatabase = container.privateCloudDatabase
        privateDatabase.fetchRecordWithID(recordID!) {newRecord, error in
            if error != nil {
                print(error)
            } else {
                NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
                    print(newRecord)
                })
            }
        }
    }
}

创作：

func addNewRecordsSub() {
    let subscription = CKSubscription(recordType: "UserRecords", predicate: predicate, options: .FiresOnRecordCreation)
    let notificationInfo = CKNotificationInfo()
    notificationInfo.alertBody = "OK!"
    notificationInfo.shouldBadge = true
    subscription.notificationInfo = notificationInfo
    let privateDatabase = container.privateCloudDatabase
    privateDatabase.saveSubscription(subscription) { subscription, error in
        if error != nil {
            print(error)
        }

    }
}

在 CloudKit 的仪表板中出现启动订阅后：

但是当我添加新记录时什么都没有发生……什么都没有。我错过了什么吗？
