Is swift-lldb only actively supported for debugging xcode projects?
Swift in general is cross platform (runs on windows, linux, android,
etc), and I don't generally target iOS or use Xcode. I'd very much
like to get non-iOS non-Xcode debugging up and running, and I'm
curious what the current status there is expected to be.

So I would suggest building a simple example with it and watching the compile options and the linker options and all of them are very important... I gave up on doing manual builds because of this and I let Xcode do it.
