title: Unwind Segue with Multiple Storyboards
body: <p>I have been working on a project that is starting to get rather large to retain in one storyboard. I have successfully used segues and unwind segues as I need to tranfer information between views.  When I split the project into more storyboards the unwind segues do not always work.  I have researched this site and have also done some investigative work in a test area.</p>
  
  <p>In my test area if I am starting with a view controller in the main storyboard segue to a controller in a new storyboard I can unwind with no problem. If I start from a controller in a new storyboard, call it A.storyboard and segue to a controller in storyboard B, I cannot unwind. It is not finding the unwind action. I assume it is looking at view controllers in main.storyboard and not finding the action. There is something I am missing in working with multiple storyboards. Is there a way to specify the storyboard to go back to ?</p>
  
  <p>Before I wrote this question I had looked at 'Can an Unwind Segue work between two storyboards'. Both the answers work if I want to go back to Main.Storyboard. This was already working for me.  So if I have main going to second storyboard I can get back to main.This works for any number of storyboards However if I have third storyboard and want to go to fourth storyboard I cannot get back to third storyboard. I have used both of the ways suggested in the 2duplicate" question. I see the IB Action to select but it just doesn't work. Is it something I am doing wrong in setting up new storyboards ? </p>
