title: Unwind Segue not working in iOS 8
body: <p>I have an app, that works fine under iOS 7, but when built for iOS 8 the unwind segues are not working.</p>
  
  <p>I created a new project and added a modal (navigationcontroller with tableviewcontroller)and tried to use an unwind modal. Unfortunately it doesn't work either. The methods that are being unwind to, are in the desination view controller. The unwind segue is created through the storyboard (a Navigationbar button in the tableviewcontroller) When I tap the button, nothing happens. There is no log output and the modal does not disappear. It also only seems to affect modal segues. push/popover are unwound normally.</p>
  
  <p>Has anyone had a similar problem and has an Idea how I could solve it?</p>
