Symbol completion for Package.swift from SwiftPM project in a subfolder doesn't work

[adam-fowler]

If you have a SwiftPM project in a subfolder of a VSCode workspace, SourceKit-LSP does not provide symbol completion, hover documentation for the Package.swift file even though a workspace/didChangeWorkspaceFolders request that adds the subfolder has been sent.

See swiftlang/vscode-swift#768

I'm not sure if this is related, but in one of my projects, I keep getting a "No such module" error from SourceKit in a regular file, not Package.Swift. One of the Code Helper processes also spins up to 100% CPU.

This is using a 6.0 snapshot. With 5.9, everything is fine.

Could you file a separate issue for this? It seems like a different issue to me. Some initial thoughts:

Did you build your project with the Swift 6.0 snapshot as well? If you build your project using a different toolchain than the one that contains your sourcekit-lsp, SourceKit isn’t able to read your Swift modules, which might cause the issue.
