It looks like build rules don’t yet support input files, although XcodeProj does.

Research direction
Investigate how build rules are currently implemented in XcodeGen (likely in the project generation code). Check XcodeProj library for support for input files in build phases. Look at similar features already implemented for other build phases to model the approach. The issue suggests that XcodeProj already supports input files, so the task is to extend XcodeGen's specification and processing to include input files in build rules.
