    let url = NSURL(string: "http://ift.tt/1rAAixy")

    let task = NSURLSession.sharedSession().dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in

        if url != nil {

            let urlContent = NSString(data: data, encoding: NSUTF8StringEncoding)
            println(urlContent)
        }
    })
