I prefer flexbox to auto layout in Xcode, actually. In fact, for Mac apps I've always turned off auto layout and gone back to springs and struts, since they're so much simpler...
I'd actually equate auto-layout when it was first introduced to the current state of flexbox. It can do what you want but boy are there some gotchas along the way.
It has gotten a lot better - the pain point with autolayout remains when when you need to add constraints in code - then it's a painful API. In UI, it is quite a pleasure to work with I find.
I wonder when that's coming to web dev - a GUI for web layout using flexbox would make a lot of people happy. The reason dreamweaver and the like didn't work well is because there were too many gotchas, do this in javascript, that in css, etc.
With flexbox, css selectors and some good plug'n'play javascript components (carousel, etc, everything bootstrap offers basicaly) - I can see a tool like Dreamweaver making a big comeback. What do you think?
