swift的AVOSCloud子类不能用怎么办？？？

Question

照文档写了swift 却报错。。
"Student.Type" does not have a member named 'registerSubclass'
求解，，ＳＷＩＦＴ不能用子类吗？？

把Student这个搞成ＯＣ，混编没问题，，我发里写错了吗？？？

class Student:AVObject,AVSubclassing{
    var name:NSString = ""
    class func parseClassName() -> String! {
        return "user"
    }
}

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
        Student.registerSubclass()//这里把错"Student.Type" does not have a member named 'registerSubclass'
        AVOSCloud.setApplicationId("＊＊＊＊＊＊＊＊", clientKey: "＊＊＊＊＊")
return true
    }
