Yang Qin developed core build system features for the bazelbuild/rules_apple and bazelbuild/rules_swift repositories, focusing on command-line tooling and mixed-language build support. In rules_apple, Yang enhanced hmaptool to accept response files, enabling arguments to be read from files for more reliable and maintainable Apple toolchain builds. For rules_swift, Yang implemented Swift plugin support in the mixed_language_library rule, introducing a new attribute to configure plugins and updating documentation accordingly. Using Swift, Starlark, and Bazel, Yang’s work addressed complex build scenarios, improved build performance, and reduced manual errors, demonstrating depth in build system configuration and file I/O handling.
