RemoteNotification字典已更改，而CKNotification字典现在已不同

Question

我希望有人能指导我...我知道Swift 2.0/ Xcode 7还在测试版，但我需要转换我的代码...这是我的代码。

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        let notification:CKNotification = CKNotification(fromRemoteNotificationDictionary: userInfo)
        //application.applicationIconBadgeNumber = 0
        if (notification.notificationType == CKNotificationType.Query) {
            let queryNotification = notification as! CKQueryNotification
            let recordID = queryNotification.recordID
            receivedRecord = recordID
            NSNotificationCenter.defaultCenter().postNotificationName("updateDatabase", object: nil)
        }
    }

因此，CKNotification的预期Dict已更改为String:NSObject ->之前是NSObject:AnyObject，这符合返回的Dict！函数(DidReceiveRemoteNotification)返回的字典是: NSObject : AnyObject

摘自Xcode7 ->公共便利初始化(fromRemoteNotificationDictionary notificationDictionary: String : NSObject)

摘自Xcode6.4 ->便捷初始化！(fromRemoteNotificationDictionary notificationDictionary: NSObject : AnyObject!)

所以，我的问题是，我如何转换它，或者我遗漏了一些明显的东西？这可能是个bug吗？

感谢您的指导/帮助...

执行以下操作：

if let userInfo = userInfo as? [String: NSObject] {
    let notification = CKNotification(fromRemoteNotificationDictionary: userInfo)
    ...
    ...
}
