Updated 12 September 2014: The playground is now updated for Xcode 6.0 GM! We'll be running a workshop on Swift at /dev/world/2014 as well, if you want to learn more!

We've been spending the last week learning Swift, Apple's new programming language. So far we're very impressed! We put together a playground to test out, showcase, and learn the new language and syntax. We thought it might be useful, so we've put it up on our GitHub. 

Let us know what you think! If you'd like to learn more about Swift, iOS programming, and even Objective-C (which you should still learn, in our opinion), check out our training!

Don't forget to check out our brief thoughts on WWDC 2014 as well.
