Developed the Core Data Model Output Granularity feature for the bazelbuild/rules_apple repository, enabling developers to explicitly specify which Swift files are generated by the apple_core_data_model rule. This enhancement provided finer-grained control over build artifacts, moving beyond the previous approach of returning only the containing directory. By leveraging Bazel, Starlark, and Swift, the work streamlined build processes and reduced the need for manual post-processing, supporting more flexible and automated CI/CD workflows. The implementation focused on improving artifact management within build systems, allowing teams to better tailor their outputs and integrate Core Data models more efficiently into their projects.
