I think UIStackView would be much simpler solution for this ;)

UIStackView is a step in the right direction, but it doesn't go far enough. It's still not truly declarative; it requires you to think in terms of content priorities; and it doesn't support z-ordering.

I rarely use them unless I have a "just fill this space between eachother" problem.
