Creating an asyncTask in swift

How can I create an asyncTask in Swift? I want to call my loadPage() function in the background (which will load the page from server), and I want to handle the response in postExecute(after background task)

You can use the Grand Central Dispatch to run threads.

class ThreadsFromSwiftEssentialsBook {
    class func runOnBackgroundThread(fn:()->()) {
        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),fn)
    }
    class func runOnUIThread(fn:()->()) {
        if NSThread.isMainThread() {
            fn()
        } else {
            dispatch_async(dispatch_get_main_queue(), fn)
        }
    }
}
