I was reading the documentation:
You need to decide how many children can be displayed by your view
controller at once, when those children are displayed, and where
they appear in your view controller’s view hierarchy.
But in which method should I position the view controller children’s view? Say I have two UIViewController in the container and I want one next to the other.. how do I do this?
In one of my articles I demonstrated how to create a simple dashboard app using UIViewController Containment.
