Echo JS isn't just for JS topics.
Per http://www.echojs.com/about:
"Echo JS is a community-driven news site entirely focused on JavaScript development, HTML5, and front-end news."
That covers a lot ground _outside_ of JS; CSS3, performance, workflow, etc. Now granted, Swift isn't a JS capability per se, however, JS devs are a target audience for Swift (along with Cocoa and Objective-C devs), so I still thought this was appropriate to post.
