A curated list of awesome Swift playgrounds.

Contributing

Please take a quick look at the contribution guidelines first. Thanks to all contributors; you rock!

If you see a playground here that does not work anymore with the current release of Xcode or is not a good fit, please submit a pull request to improve this file or consider updating it, thank you!

Downloading all the playgrounds

Unless otherwise indicated, all playgrounds are compatible with Swift 3.

All the playgrounds are available as submodules in the playgrounds/ directory, to download them all in one go, just clone this repository with git clone --recursive https://github.com/uraimo/Awesome-Swift-Playgrounds.git or execute git submodule update --init after you have cloned the repository the usual way.

Apple's playgrounds distributed as zip archives have to be downloaded manually.
