sourcekit-lsp works really well, VSCode integration is solid[1]. I've been using VSCode+dev-containers+sourcekit-lsp for a couple years now for Linux development on macOS and it has been really nice.

I agree that this is a must-have for idiomatic Swift. It is really hard to write the long-named-functions and get all the variable names correct without reasonable autocomplete.

I was curious and noticed that this looks reasonable: https://github.com/emacs-lsp/lsp-sourcekit

Emacs + lsp-mode + sourcekit + company-mode etc looks reasonably close to what I get with Rust in Emacs.

If I were doing application development I'd maybe consider Swift.

VS Code isn’t too bad, it after ~20 years of Xcode/Project Builder, muscle memory for keybinds and UI in general is strong. Hoping that someone uses the LSP to write a cross platform “Xcode Lite” or something along those lines.

It wasn't too bad to switch for me, but the problem is going back and forth. I don't love over-customizing my IDE but I've created my own keybindings for the commands I mis-type most (Command-R to run being the main culprit). Both Xcode and VSCode support custom key bindings and this isn't something that the LSP is responsible.

UI is a different matter. Xcode is still miles ahead in performance tooling.
