Swift Standard Library.playground

Apple has already posted the sample code for WWDC 2015, and one of the sample projects is a playground about the Swift Standard Library.

The playground covers two of the most important topics in the standard library:

It’s a great addition to Apple’s Swift book because you can play around with the code and the explanations in the playground are more extensive than in the book. It “only” covers the standard library, however, so language features like the new try/catch error handling syntax are not included.

The playground requires Xcode 7. To see the page structure, make sure to show the Project Navigator. And if you’re seeing the raw documentation comments, choose Editor > Show Rendered Markup to switch to the formatted view.
