title: How to Pass information Back in iOS when reversing a Segue using Swift?
body: <p>I have two view controllers, One and Two. I go from VC One to VC Two. On VC Two, I select some data that I store in an array. When I press the "Back" button on the navigation bar, I would like to send that array back to VC One.</p>
  
  <p>What's the best way to do this using Swift &amp; Storyboards?</p>
  
  <p>Thanks!</p>
