NSURLSession标签不更改文本Swift XCode 6

Question

I'm trying to use NSURLSession to get data from a website and display it in the label. The data is displaying in my println and the background is changing color based on the data but does not print the data in the label. Thanks in advance for the help!

The following code is in my viewDidLoad() function:

let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in

            var urlContent = NSString(data: data, encoding: NSUTF8StringEncoding)

            if urlContent!.containsString("<div class=\"currentStatus warning\">") {

            var contentArray = urlContent!.componentsSeparatedByString("warning\">")

            var newContentArray = contentArray[1].componentsSeparatedByString("</div>")

            var statusNS = newContentArray[0] as NSString

            var stat = newContentArray[0] as String

            dispatch_async(dispatch_get_main_queue(), {
                println(stat)

                self.statusLabel.text = stat

                if statusNS.containsString("closed") {
                    self.view.backgroundColor = UIColor.redColor()
                } else {
                    self.view.backgroundColor = UIColor.greenColor()
                }

            })

            } else {
                dispatch_async(dispatch_get_main_queue()) {
                    self.statusLabel.text = "Hmm...Can't seem to find out"
                }
            }

        }

        task.resume()

Make sure your statusLabel is correctly connected in Interface Builder. If you log the value of the status label, you will likely find nil .
