title: How to reset/restart viewcontroller in Swift?
body: <p>I want to have a button on my navigation bar "Reset" and I would like this to be connected to an <code>IBAction</code> to sort of "restart" the controller. </p>
  
  <p>I have some segues from another controller that changes some aspects of the <code>viewcontroller</code> (that has a <code>collectionview</code>) and I want the user to be able to start over. Does anyone have any suggestions as to how to proceed?</p>
