how to add subview over storyboard?

Question

I have a ViewController and I want to add 3 subviews in the content part.

I want to create something such that it looks like this image example:

Specifically, my questions are:

1. How to add over IB in storyboard 3 subviews (with labels and textViews)
2. How to switch them over TabBar or segment
