Build errors: missing Lock.swift, Extensions.swift in CXUtility

[garvankeeley]

Seeing errors about missing files building from master:

error: Build input files cannot be found: 'Carthage/Checkouts/CombineX/Sources/CXUtility/Extensions.swift', 'Carthage/Checkouts/CombineX/Sources/CXUtility/Lock.swift' (in target 'CXUtility_iOS' from project 'CombineX-Carthage'

Please try fix-carthage branch.

It seems that Carthage and CocoaPods integration are both broken. Now we really need #52. @luoxiu

Thanks for the suggestion, carthage build --no-skip-current run from the root of the source tree on that branch errors with:
