Dalton Claybrook 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. By leveraging Bazel and Starlark, Dalton introduced finer-grained control over build artifacts, allowing teams to select individual output files rather than receiving only the containing directory. This approach streamlines build processes, reduces the need for manual post-processing, and enhances automation in CI/CD pipelines. The work demonstrated a strong understanding of build systems and Core Data integration, delivering a targeted solution that improves flexibility and maintainability for Apple platform development workflows.
