Does anyone know if the Swift team at Apple is working on a new Swift LSP language server? There was an update in April mentioning a focus on Clangd and LSP:

I haven't heard anything about it since. In the meantime, I plan to help improve GitHub - RLovelett/langserver-swift: A Swift implementation of the open Language Server Protocol., which seems to be the most featureful language server for Swift.
Sourcegraph is actively working on improving the accessibility and quality of language servers, and since Swift is a popular language, we are focusing on providing strong support for Swift.
