Xcode 我的代码（云工具包）有什么问题

这是我的代码，允许一个警报和写入警报中的文本保存在云中。我实际上是在学习一个教程 我在我的一些代码上收到了两条错误消息

错误：任何对象与CKRecords不相同（位于self.post=post）

错误：CKRecords没有名为subscript的成员（位于newPost[“content”]

我写的代码和那个家伙在教程中写的一模一样，只是我有错误信息，而他没有！我如何修复这些错误

    var posts = [CKRecord]()



override func viewDidLoad() {
    super.viewDidLoad()


}

func loadData() {
    posts = [CKRecord]()

    let publicData = CKContainer.defaultContainer().publicCloudDatabase
    let query = CKQuery(recordType: "Post", predicate: NSPredicate(format: "TRUEPREDICATE", argumentArray: nil))
    publicData.performQuery(query, inZoneWithID: nil) { (CKRecord, NSError) -> Void in
        if let posts = CKRecord{
            self.posts = posts //Error "Any Object is not Identical to CKRecords"
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                self.tableView.reloadData()
            })
        }

    }
}

@IBAction func createPost(sender: AnyObject) {

    let alert = UIAlertController(title: "New Post", message: "Enter New Post", preferredStyle: .Alert)
    alert.addTextFieldWithConfigurationHandler { (textField:UITextField!) -> Void in
        textField.placeholder = "Your Post"
    }
    alert.addAction(UIAlertAction(title: "Post", style: UIAlertActionStyle.Default, handler: { (action: UIAlertAction!) -> Void in
        let textField: AnyObject = alert.textFields!.first!

        if textField.textLabel??.text != "" {
            let newPost = CKRecord(recordType: "Post")
            newPost["content"] = textField.textLabel??.text //ERROR "CKRecord does not have a member named subscript"



            let publicData = CKContainer.defaultContainer().publicCloudDatabase
            publicData.saveRecord(newPost, completionHandler: { (record: CKRecord?, error: NSError?) -> Void in
                if error == nil {
                    print("Post Saved")
                }
            })

        }






    }))

    alert.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
    self.presentViewController(alert, animated: true, completion: nil)

将Xcode更新至最新版本

这种语法可以从特定版本的Swift开始使用。我不记得您确切需要哪个版本，但如果您只更新Xcode，您的问题将消失
