That's cool, but I'd really like to see a version of this that doesn't use Foundation APIs (which won't be open sourced) so that we can, eventually, run this on Linux.

I thought so too but on another thread jahewson commented that Core Foundation is already open source (https://news.ycombinator.com/item?id=9739424). It's all here: http://www.opensource.apple.com/source/

I'm not sure though whether these are the current versions or something older.

These are the current versions, if you go a directory higher, you'll find a way to see the foundation implementation for each OS version:

They usually appear with around 3-6 months delay after the initial operating system release

Sweet, didn't know that. I don't think that Foundation will be be packaged with "open-source" Swift, so making use of it on Linux won't be trivial. Plus, it'd be preferable not to have to use Foundation in either case IMO.

Ah, I was just wondering about Foundation in the open sourced version. Thanks.
