即使我在warnParSEOperationOnMainThread上添加了一个符号断点,它也不会破坏

这是应用程序委托的代码片段

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0)) {
            Parse.enableLocalDatastore()

            Parse.setApplicationId("XXX",clientKey: "YYY")
            PFAnalytics.trackAppOpenedWithLaunchOptionsInBackground(launchOptions,block: nil )

            var defaultACL = PFACL()
            defaultACL.setPublicReadAccess(true)
            defaultACL.setPublicWriteAccess(false)
            PFACL.setDefaultACL(defaultACL,withAccessForCurrentUser:true)

            CAUser.registerSubclass()

            NSLog("App finish loading")

            dispatch_async(dispatch_get_main_queue()){
                () -> Void in
                // any UI updates need to happen in here back on the main thread
            }
        }

        return true
    }

感谢有人向我强调,为避免此警告消息缺少什么？
