very cool! this article would have saved me quite some time if I discovered it earlier, as I ended up diving into a similar rabbit hole. Still, some useful tips I will incorporate into my emacs workflow, cheers for that.

one thing to add: I recommend piping the output to `xcbeautify` (https://github.com/cpisciotta/xcbeautify) to have sane build output; otherwise it's a mess outside of xcode.
