Can an 'Unwind Segue' work between two storyboards connected by a storyboard reference?

Question

In iOS 9, storyboards can be connected by a \'storyboard reference\' that links to a second storyboard by adding a storyboard reference and setting the \'referenced ID\' to

Answer 1

1) Add this method to your MainViewController

// NEEDED! Do not delete!
@IBAction func unwindToMasterViewController(_ segue : UIStoryboardSegue) {
  // Do nothing
}

2) In the Main storyboard, right-click on the Exit segue of the referenced storyboard and select unwindToMasterViewController

3) Give the exit segue a name to reference it in code

4) Call your exit segue from code

Answer 2

I didn't have to make a storyboard reference back from the 2nd storyboard to the first as Ryan laid out. For me, in my second storyboard I could Control-drag from a viewcontroller to its own exit, and the unwind segue that I had specified in a viewcontroller class consumed in the first storyboard appeared. So I just selected that to create a new exit segue with an identifier, and called performSegueWithIdentifier: on it in code. Worked fine.

Answer 3

Starting from your storyboard reference, create a new storyboard reference that will be a reference back to your "Main" storyboard. Make sure you set your Storyboard Identifier on your main as well.

You will now have a "Main Scene" reference with all you Exits now available. You can now create unwind segues as you normally would. Ctrl-drag from your controller to the Exit marker on the Main Scene and you will be able to select the desired exit.
