Building iOS Apps with Doom Emacs

I shipped SPEEM, my first iOS app, from Doom Emacs. Not from Xcode.
I don’t mean I just edited a few files in Emacs and switched back when it was time to build. I mean the whole loop: write Swift, build, boot a simulator, install the app, launch it, stream logs, restart LSP, scaffold new projects. All from inside Emacs, all driven by SPC i keybindings I wrote myself.
This post is about how, and why it’s even possible.
