This post is from the Activity iPhone Duo UIKit Q&A.
Hi, For iPhone Duo, is there updated guidance about using container view controllers inside other container view controllers? For example, using UISplitViewController as the root view controller inside a UITabBarController tab (and doing this for multiple tabs)?
Hello! This guidance has not changed for iPhone Duo. It is still appropriate to have a UITabBarController tab (or more) with a UISplitViewController.
UIArrangementViewController is an exception: Do not embed a UINavigationController or any other controllers that navigate in an arrangement view controller. A UISplitViewController is the right control to use if you need to embed a UINavigationController.
