swift NSURL gets back an "unable to read data" message even with https://

I am trying to learn iOS following a course and they ask to do the following:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    //var string1 = "http://www.google.com"
    //var string1 = "https://www.weather-forecast.com/locations/San-Antonio/forecasts/latest"
    //var url = NSURL(string: string1)
    var url = NSURL(string: "https://google.com")

    print(url)

        if url != nil {

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

                var urlError = false

                if error == nil {

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


                } else {

                    urlError = true

                }

                if urlError == true {
                    self.showError()
                }
        })

            task.resume()

        } else {

            showError()

    }
}

the app doesn't show any web page content and when debugging I find that the object for the url says that it is "unable to read data"

I have tried with http and https. I have tried with different web sites.

I have tried the address in the safari of the simulator and it loads.

Can someone tell me why is this not working

Thanks in advance. gariva

For display web page you should use UIWebView element. Something like this: 

        let url = NSURL(string: "https://google.com")
        let webView = UIWebView(frame: self.view.frame)
        self.view.addSubview(webView)
        webView.loadRequest(NSURLRequest(URL: url!))

You're using wrong encoding. The webpage you're trying to fetch (http://www.google.com/) uses ISO-8859-1.

enter image description here

I was able to reproduce your issue. Fetch worked when I changed encoding. Try this:

 var urlContent = NSString(data: data!, encoding: NSISOLatin1StringEncoding)
