The toolchain has been installed to:

You can find the Swift binary at:

#{opt_prefix}/Swift-#{version}.xctoolchain/usr/bin/swift

You can also symlink the toolchain for use within Xcode:
|

ln -s #{opt_prefix}/Swift-#{version}.xctoolchain ~/Library/Developer/Toolchains/Swift-#{version}.xctoolchain
