Good tip. Another suggestion would be to use chroot :) That said, the best, most foolproof way of doing this really comes down to using OS X to virtualize OS X. Or you could try cross-compiling. It seems to work here: https://github.com/swift-x/tools https://github.com/swift-x/tools (which looks interesting...) It's possible that by the end of this week, maybe next, it will be very easy indeed to compile and/or run Swift on Linux from Linux, at which point you could try LXC or a million other ways to virtualize.
