Added SwiftSyntaxHighlighter using SPM in new macOS project and got error:

When do you get this error? Is it when you try building and running your package executable with Xcode?

yes, on running with Xcode.

@bonyadmitr Thanks for confirming. This looks like the same issue as SwiftDocOrg/SwiftSemantics#2:

Until a better solution is provided upstream, my suggestion would be to run swift package generate-xcodeproj to generate an Xcode project and then xed <#Package#>.xcodeproj to open the generated project directly.

yea, seems the same.

maybe it should be fixed by doc link:
https://github.com/apple/swift-syntax#embedding-swiftsyntax-in-an-application

i tried it but couldn't build it yourself from the Swift repository, . i got build-parser-lib script error.

and thanks for answer!

I was able to get this working in Xcode 12.5 using the latest OSS Toolchain. I just updated the README with details about how to do this with 72f1496.
