Questions tagged [unwind-segue]

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.
