This is a pretty great one-stop-shopping resource for Auto Layout by Paul Hudson.
The Auto Layout cheat sheet – Hacking with Swift
Auto Layout is a powerful tool for creating flexible, maintainable rules for your user interface. It can also be a real brain vortex if you’re unlucky – it’s something that makes hard things easy and easy things hard.
To help relieve the pain, in this article I’ve put together code snippets to solve a variety of common Auto Layout problems: creating constraints, animating constraints, adjusting constraints at runtime, and more.
As with all of Paul’s articles, it’s well thought out, and it’s a useful resource to stash away for the next time you need to do in-code work with Auto Layout and Swift.
It is disappointing that he does not use the word “vexing” anywhere this blog post as I had thoroughly expected him to do (and would have been so appropriate in any article about Auto Layout), but the tips are so good, I’ll overlook it this time.
Excellent resource.
