What does A> mean in the left margin?

[realh]

I've just started using vim-lsp for editing Swift. When I load a Swift file it displays 'A>' in the left margin on a seemingly random line, then the 'A>' moves to the current line when I place the cursor. What does the A> mean? Can I disable it? I like to use the appearance of the left margin as a handy indicator that I've got a problem somewhere in the file.

It means there is a code action. you can use :LspCodeAction to see what is there. It is similar to bulb in vscode.

Unfortuantly some language servers always shows it while some lang servers are better at showing.

Yes, you can disable it. #1085

This is now documented. Use :h vim-lsp and the search docs using /A>.
