[swift-corelibs-dev] Building Foundation in Xcode

Mon Mar 14 09:49:25 CDT 2016

Hi David,

You need the latest Foundation from git, I think.  Brian fixed that
compilation problem here:

https://github.com/apple/swift-corelibs-foundation/commit/9fbcf1be1b75d5d9046735f13eddbaef4b3a408a

It would be really nice if the snapshots at
https://swift.org/download/ could be refreshed!

Thanks,
Ian
