title: How to convert a string UTC date to NSDate in Swift
body: <p>I'm getting UTC string dates that look like this "2015-10-17T00:00:00.000Z" and want to convert them to an NSDate in this format "October 12th 2015 11:19:12 am"</p>
  
  <p>This is the route that I'm trying but I can't seem to get the right dateFormat.</p>
  
  <pre><code>let dateFormatter = NSDateFormatter()
  dateFormatter.dateFormat = //can't seem to get this right
  dateFormatter.timeZone = NSTimeZone(name: "UTC")
  let date = dateFormatter.dateFromString("2015-10-17T00:00:00.000Z")
  </code></pre>
