title: UIStoryboardSegue versus presentviewcontroller?
body: <p>Someone can explain the difference between use of <code>UIStoryboardSegue modal</code> versus programmatically <code>presentViewController</code>?</p>
  
  <p>Use <code>UIStoryboardSegue</code> is only to facilitate? Or have some performance benefit?</p>
  
  <p>Thank you</p>
