Social Framework on iOS8 using Swift Language

It's very simple, I am currently following this Topic: Social Framework iOS 8 swift and I have successfully finished it. Here is my complete code in Swift:

On a ViewController.swift:

@IBAction func shareFB(sender : AnyObject) {
    if(SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook))
    {
        var SocialMedia :SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)

        SocialMedia.completionHandler = {
            result -> Void in


            var getResult = result as SLComposeViewControllerResult;
            switch(getResult.toRaw()) {
            case SLComposeViewControllerResult.Cancelled.toRaw(): println("Cancelled")
            case SLComposeViewControllerResult.Done.toRaw(): println("It's Work!")
            default: println("Error!")
            }
            self.dismissViewControllerAnimated(true, completion: nil)
        }
        self.presentViewController(SocialMedia, animated: true, completion: nil)
        SocialMedia.setInitialText("Test a Post on Facebook")
    }


}

Run your application, It's work fine!
