Is `textDocument/inlayHint` supported?

[wojciech-kulik]

I wonder if there is a support for textDocument/inlayHint. It looks like there is because I found this PR: #465

However, when I try to request data I get:

Method not found: textDocument/inlayHint

It’s also weird that VS Code somehow is able to get those hints from the LSP.

In VSCode if you set the setting swift.sourcekit-lsp.server.trace to verbose you can see all the communication between the VSCode LSP client and SourceKit-LSP in the SourceKit-LSP output pane. Useful for debugging requests. Search for InlayHint and you should see the requests.

@adam-fowler thank you for the advice! I checked it in VSC and it turned out that my request is the same. I went back to Neovim, tried again and it started working :D. I must have called it for an incorrect buffer where sourcekit-lsp was not attached. Thank you for the help!
