swift - RemoteNotification Dict 已更改，CKNotification Dict 现在不同

Question

我希望有人可以指导我...我知道 Swift 2.0/Xcode 7 仍处于测试阶段，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] ，与返回的 Dict 一致!从函数(didReceiveRemoteNotification)返回的 Dict 是: [NSObject : AnyObject]

取自 Xcode 7 -> 公共(public)便利 init(fromRemoteNotificationDictionary notificationDictionary: [String : NSObject])

取自 Xcode 6.4 -> 方便 init!(fromRemoteNotificationDictionary notificationDictionary: [NSObject : AnyObject]!)

所以，我的问题是，我该如何转换它，或者我是否错过了一些明显的东西？这可能是一个错误吗？

感谢您的指导/帮助...

这样做:

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