I have a UIViewController inside which I have a Container. I want to be able to change the UIViewController inside that Container. I think I can manage the Segue calls to make that happen but how do I connect multiple UIViewController objects (and their related Segues) on a Storyboard with UIBUilder?

Here you can see my basic layout and that I've attached one UIViewController to the Container. Now I want to attach the second to it on the Storyboard in the same way and manage both in code.
