During the month, contributed to the square/workflow-swift repository by focusing on codebase cleanup within Xcode templates and tests. The primary task involved removing the unused workflowDidChange method, which eliminated dead code and simplified the project structure. This change, implemented using Swift and leveraging expertise in iOS development, improved maintainability and reduced the risk of future template maintenance issues. By streamlining the code, the update also facilitated clearer onboarding and enabled faster future changes for other developers. The work demonstrated attention to detail in code hygiene and a methodical approach to maintaining a clean, efficient codebase without introducing new features or bug fixes.
