Worked on the mrousavy/swift repository over two months, focusing on enhancing ABI reliability and platform-specific availability in Swift tooling. Delivered features such as ABI breakage enforcement, introducing a command-line flag to treat ABI issues as hard errors, and implemented blocklist-based indexing to reduce noise without altering compiler sources. Refactored indexing logic for improved maintainability and performance. In February, extended the API digester to support visionOS availability, updating data structures and logic to handle declarations exclusive to visionOS. Leveraged C++, Swift, and expertise in compiler internals, API design, and build systems to improve release quality and downstream stability.

Feb 1, 2025February 2025 performance summary for mrousavy/swift: Implemented VisionOS Availability Support in the API Digester. This work enhances the ABI checker to correctly handle declarations exclusive to visionOS, updates data structures and digestion logic to include visionOS availability, and adds a new visionOS availability method. The change is captured in commit 87877bd95fd32db38dc0167c659d1f13cfd7a33a with the message 'ABI checker: avoid diagnosing missing availability info for decls that are only explicitly available on visionOS'.

Jan 1, 20252025-01 Monthly summary for mrousavy/swift: Focused on improving ABI reliability and indexing configurability to boost release quality and downstream stability. Key features delivered include a new ABI breakage enforcement mode and blocklist-based indexing with non-invasive configuration. A minor refactor removed a duplicated string copy in indexing for maintainability. There were no major user-visible bug fixes this month; the changes reduce risk of ABI regressions, minimize indexing noise, and improve build determinism. Technologies demonstrated: Swift tooling integration, CLI flag propagation, driver-to-diagnostic pipeline, and non-invasive code cleanups.
