title: Xcode 6 error 'URLWithString' is unavailable?
body: <p>Please help a newbie here. I'm sure this is stupid simple.</p>
  
  <p>I'm following along and learning Xode nicely, but I'm stumped on a basic connection to a URL:</p>
  
  <pre><code>var text = textField.text
  var url = NSURL.URLWithString(text)
  var request = NSURLRequest(URL: url)
  webView.loadRequest(request)
  </code></pre>
  
  <p>I'm getting the following error for the second line above:</p>
  
  <p><strong>'URLWithString' is unavailable: use object construction 'NSURL(string:)'</strong></p>
  
  <p>(code is part of a brief tutorial at: <a href="http://www.lynda.com/articles/build-first-ios-app-swift">http://www.lynda.com/articles/build-first-ios-app-swift</a>)</p>
