title: How can I get my current date ios Swift?
body: <p>Specifically I would like to <code>print</code> my current date formatted like this -  <code>2016-12-08 03:37:22 +0000</code>.  I've tried NSDateComponents.  Swift 2.1 is telling me <code>NSSecondCalendarUnit</code> is deprecated and it doesn't recognize <code>NSCalendarUnitSecond</code>.  What is the best way to do this?</p>
