For the view on the left, choose from the Editor\\Pin menu: Top Space to Superview Leading Space to Superview For the view on the right, choose: Top Space to Superview Trailing Space to Superview And for the big view at the bottom: Leading Space to Superview Trailing Space to Superview Bottom Space to Superview

Answer 2

from your question I got that you want to make the red view size and origin wont change after rotation.

Use width, height, left, and top in autolayout. It makes red view position always in top left without any size changed.

Here the results :

Before rotation

After rotation
