It's also interesting to see the graph of contributors (https://github.com/apple/swift/graphs/contributors https://github.com/apple/swift/graphs/contributors). I noticed for example that Slava Pestov (The creator of the Factor programming language) has made a number of commits. Apple has hired some really smart people to work on Swift! Edit: Also jckarter the creator of the Clay programming language is in there too!
