Unwind segues give a way to "unwind" the navigation stack back through push, modal, popover, and other types of segues. use unwind segues to "go back" one or more steps in navigation hierarchy. Unlike a normal segue, which create a new instance of their destination view controller and transitions to it, an unwind segue transitions to an existing view controller in navigation hierarchy. use these callbacks to pass data between the view controllers.

Unwind Animation - Duplicate View Behind Dismissed View
Extremely strange problem here: When unwinding from VC3 to VC1, VC3 animates down and behind it is VC3! Then that goes away and I'm back to VC1. It all happens in about 1 second, but it's clearly a duplicate. Anyone know why?
