[swift-build-dev] Customizing location of source directory

I don’t quite understand your questions. This is what I do:

1. Download and install latest swift for darwin
2. xcrun launch-with-toolchain /Library/Developer/Toolchains/swift-latest.xctoolchain
3. ⌘B

Then to use this swift-build you just execute it:

    .build/debug/swift-build
