During October 2024, Helmetcrest developed a Java API Benchmarking Framework for the swiftlang/swift-java repository, enabling cross-language performance analysis between Swift and Java. They implemented benchmark definitions in both languages and configured Gradle and SwiftPM build systems to support reliable, end-to-end benchmarking of Java API calls within the Swift-Java interoperability stack. Their work included resolving build and dependency issues by reorganizing Package.swift, removing redundant executable targets, and updating plugin versions for compatibility. Helmetcrest applied skills in benchmarking, build system configuration, and Java Native Interface (JNI), establishing a foundation for data-driven performance optimization and improved maintainability within the project.

October 2024 monthly summary for swiftlang/swift-java: Delivered Java API Benchmarking Framework and stabilized the build for Java API benchmarks within the Swift ecosystem. Implemented benchmarking definitions in Swift and Java, configured builds to support cross-language performance analysis, and resolved build/dependency issues to ensure reliable benchmark execution. Established foundation for data-driven performance optimization of Swift-Java interop and improved maintainability by removing a duplicate executable target and aligning plugin versions. This work enables measurable performance improvements and supports future optimization efforts.
