Worked on the VoiceInk repository to enhance local build reliability and licensing compliance within a one-month period. Addressed a persistent issue where stale VoiceInk.app artifacts were reused by implementing isolated local build artifact handling using Makefile and Xcode. The solution involved directing builds to a dedicated .local-build/ directory and ensuring the correct app version was always produced, reducing risks of outdated binaries and licensing bypass. By preserving SWIFT_ACTIVE_COMPILATION_CONDITIONS overrides and updating the build workflow, the developer improved reproducibility and reliability of local builds. This work streamlined developer productivity and strengthened licensing checks in the local development environment.
