[swift-corelibs-dev] [XCTest] Cannot build using XCode

[Brian Croom]

That's right, breaking changes have been made to Swift since the latest
toolchain snapshot was released, and Corelibs Foundation has been updated
accordingly.

Until the next snapshot, an alternative to building your own toolchain
would be to check out an older commit of Foundation which still builds with
the compiler in the snapshot toolchain, since XCTest doesn't depend on any
of the more recent Foundation changes. I've had success using this commit:
