New LSP language service supporting Swift and C-family languages for any editor and platform

I also like Xcode and would like to use it to edit Rust. It has its own implementation of LSP (rls). I was wondering if adding support for LSP would make Xcode more open to other languages having LSP implementations.

Getting Xcode to use our new LSP service should make it viable to use other LSP services as well, and it’s something that we are interested in, but we don’t have specific plans to announce at this moment. Our primary focus will be to get the new LSP service integrated and a complete replacement for the existing internal mechanism.
