In Swift at Apple: Migrating the Password Monitoring Service from JavaThere is a Swift LSP. See - https://github.com/swiftlang/sourcekit-lsp
In Security research on Private Cloud ComputeThere's already an LSP server for Swift (also made for Apple): https://github.com/apple/sourcekit-lsp
This library is intended for syntactic tools: formatters, highlighters, that kind of thing.
In Swift Syntax and Structured Editing LibraryNo langserver? SourceKit LSP has been around for a while now: https://github.com/apple/sourcekit-lsp
In Highlights of new technologies introduced at WWDC 2021> it still requires conditional compilation to import either Darwin or Glibc, instead of Foundation
Well, swift-corelibs-foundation has made a lot of progress, and strictly speaking, to a certain point you don't actually want to hide some of the implementation details from the developer. This isn't Java - natively calling out to C is a thing that Swift can and will do.

Do tell. What other concerns do you have? You seem deeply misinformed. While Swift may not yet have an ecosystem outside of Apple, it is factual

ly incorrect to say that it is not usable outside of it.
Apart from the fact that you ignored the other two arguments I made, the LSP is not production ready. It even says so on its very own github page: https://github.com/apple/sourcekit-lsp#status
