Animating Autolayout Constraint Changes

Keith Harrison on Animating Autolayout Constraints:

“If you start using autolayout you quickly learn that you should not directly change the frame (or bounds or center) of a view. Instead you need to change the autolayout constraints. This post walks through a simple example showing how you can achieve the same view animation effects using autolayout.”

I always appreciate insightful posts on Autolayout.
