title: Unwind To Specific ViewController Without NavigationController
body: <p>I am trying to unwind to a specific viewController without using navigationController. For instance, I have a set of questions the user needs to answer. Depending on their answer they either need to get unwound to the root controller or the first question. I am aware of how I would go about navigating them to the root controller, I just don't know how to go back to any other specific controller. I am under the understanding that if I were to use a segue to go from viewController 4 -> 2 it would use more memory and the stack could end up like 1->2->3->4->2 etc... </p>
  
  <p>Any suggestions would be greatly appreciated.</p>
