Nice article. How has lsp mode been with Emacs? I've been continuously battling slow downs and hangs using lsp mode w Python and have tried many approaches like lsp-bridge which tries to do the majority of the work outside of emacs.

Pretty good to be honest. I got much performance problems and cache inconsistencies with Rust lsp server than with Swift’s. The responsiveness is not in par with Xcode but the overall experience is quite good in my experience. My machine is a MacBook Pro M1 BTW.
