Document usage with XCode projects

[sargunv]

I was able to get this extension working with my macOS app XCode project using https://github.com/SolaWing/xcode-build-server. Setup only required generating a buildServer.json using:

brew install xcode-build-server
xcode-build-server config -workspace *.xcodeproj/project.xcworkspace -scheme Debug

But it took a ton of digging to find this tool. Ideally, documentation should surface it.

I would happily review any PR to improve docs/src/languages/swift.md

I've tried everything the LSP just doesn't want to find ContentView at all. As you can see, there is a buildServer.json telling SourceKit where to find its stuff but it just isn't working

This would be better discussed in the thread I mentioned above, or the xcodebuildserver project (the swift plugin itself isn't concerned with xcode projects), however:

• The usual solution to this sort of thing is to build the scheme in xcode, then restart Zed (or just the language servers).
• Xcode might have started using a different derived data folder for your project (compare with the reference in your buildServer.json) in which case configure xcodebuildserver again
• Rarely I have had to wipe out xcodebuildserver's cache to get a clean start
• You could check Zed's LSP logs for any weirdness (icon bottom left)
