Custom Relationship Segue

Question

As scenes in Storyboards can not be connected using IBOutlets, segues would be a great way.

While it's easy to create custom segues, there seems to be no way to create custom "Relationship Segues".

Is that so? Only Apple can create such segues (UITabBarController's viewControllers, UINavigationController's rootController, etc.)?

Answer 1

You're correct, you cannot create custom relationship segues.

Relationships segues are different from the other segues in that they are resolved at build time. When a UITabBarController is loaded from a storyboard, all of its constituent view controllers are already 'inside' of it in the same NIB that represents the scene with the tab bar controller.
