PROFILE
Leland Jansen
Leland Jansen focused on stabilizing the Rules Apple Device Runner in the bazelbuild/rules_apple repository by addressing a crash caused by OS version strings containing non-numeric suffixes. He developed a robust parsing solution in Python that strips non-numeric characters before converting version components to integers, preventing ValueError exceptions during device deployment. This fix improved error handling and ensured reliable parsing of OS versions such as '18.3.1 (a)'. Leland validated the patch through end-to-end testing on physical devices using Bazel, demonstrating proficiency in regular expressions, device runner integration, and comprehensive validation to enhance deployment stability across evolving Apple OS versions.

Mar 1, 2026March 2026: Focused on stabilizing the Rules Apple device workflow. Delivered a robust OS version parsing fix for the Rules Apple Device Runner to prevent crashes when OS version strings include non-numeric suffixes. The patch patches rules_apple 4.5.1 and is linked to commit 8c999a894522a34a461a339ba4b01eb40a7c2eab. Example issue addressed: Rapid Security Response versions like '18.3.1 (a)'. End-to-end validation performed by bazel run an iOS application target on a physical device (build, upload, run). Impact: reduces runtime crashes, improves device deployment reliability, enabling faster releases across OS versions. Technologies/skills demonstrated: string parsing and validation, error handling, Bazel rules, device runner integration, and end-to-end testing on physical devices.
