This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/p0/y1qfxmk527j0sr9v9brcf9rwr3r6xv/T/carthage-xcodebuild.rA76xd.log

Manually trying to compile gives the following error

fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.

Both CBL and LiteCore have a script to get repository version and inject the info to the source code prior build. The git rev-parse HEAD fails only when using Carthage with XCode 9 which has git version 2.13.6 (Apple Git-96).

Actually seems to be an issue with DB018. I tried with DB016 and carthage build works fine on Xcode 8.3 and Xcode 9

LiteCore did not have / run the get_repo_version.sh in DB016. CBL did have though. I'm not sure why CBL doesn't the issue in DB016.
