title: Add query string to local HTML files
body: <p>I have codes to load local html files (html files are inside the app, not from server), but how would I go about adding query string to it. I basically want to pass data from swift into html webview. Is this even possible? Alot of examples I've found is related to html files from server, but haven't found any for html files stored inside the app.</p>
  
  <pre><code>let url = NSBundle.mainBundle().URLForResource("index", withExtension:"html", subdirectory: "www")
  let request = NSURLRequest(URL: url!)
  webView.loadRequest(request)
  </code></pre>
