title: Swift full date with milliseconds
body: <p>Is any way to print full date with milliseconds?</p>
  
  <p>For example, I'm doing this:</p>
  
  <pre><code>print("\(NSDate())")
  </code></pre>
  
  <p>But I'm just get this:</p>
  
  <pre><code>2016-05-09 22:07:19 +0000
  </code></pre>
  
  <p>How can I get the milliseconds too in the full date?</p>
