Grammar is https://github.com/alex-pinkus/tree-sitter-swift, someone just needs to go over and fix up the highlighting queries

Looked at that for doing this myself, problem is they don't include the parser.c etc. in the repository and instead advise using the crate or npm package, which helix doesn't support.

Also, LSP is included in Xcode via xcrun sourcekit-lsp or the Xcode-independent Swift toolchain from swift.org.

Hmm: https://github.com/alex-pinkus/tree-sitter-swift#where-is-your-parserc

If we supported http sources rather than git you could fetch it from the latest github actions build

Currently the work-around that we have for this is to fork the repository and check in the generated C files (for example: https://github.com/jaredramirez/tree-sitter-rescript). I have a more long-term plan that will fix this but it isn't quite ready yet.

Have to admit I don't really want to do that, I'd 100 % forget/procrastinate updating that, letting it get out of date … Maybe I'll find time to automate updating the fork, then of course I can contribute support for Helix myself.

Meanwhile, I created an issue there to include the files …
