Please add an example of how to use Swift Syntax with XcodeKit Source Editor Extensions

[Eric-Catalyst]

Description

The most natural use case for Swift Syntax would be parsing code being extracted and updated in an Xcode Source Editor Extension. Please add an example of this case.

We do already have one: https://github.com/apple/swift-syntax/tree/main/EditorExtension

Is this what you were looking for?

[Eric-Catalyst]

Yes, I think that will do it. I was looking in the Examples directory, so missed the extension. Might be helpful to mention it in the main read me.

The extension itself needs a little attention as it has the following build issue when built with Xcode 15:
ld: warning: object file (/Applications/Xcode.app/Contents/Developer/usr/lib/libXcodeExtension.a[x86_64][2](libXcodeExtension.a-x86_64-master.o)) was built for newer 'macOS' version (13.0) than being linked (11.0)

Should this be a separate issue?

I don’t think that’s all too useful. There exists documentation of how to build an Xcode source editor extension and depending on swift-syntax should just be a matter of adding swift-syntax to your package dependencies.

Should this be a separate issue?

Thanks for noting. Fixing it in #2277

Thanks for your attention and assistance.
