You don't strictly have to use Xcode to use swift, there's a good LSP for use in other editors.

That said, if you're using Swift to build an app, you're probably still going to want to use Xcode for building and debugging

Yea, I'm building iOS apps mostly, and some macOS apps, so definitely need to use XCode :/

I have a nice workflow going for the iOS apps I work on where I use neovim for all my editing, and Xcode for building and debugging.
