During June 2025, Katlin focused on enhancing macOS integration for the xiaoyaocz/dart_simple_live repository by improving asset management and version control practices. Katlin implemented native icon support, ensuring the application displays correctly across all macOS icon sizes, which addressed cross-platform user experience and maintainability. To further streamline development, Katlin excluded macOS-specific artefacts such as Spotlight index files and .DS_Store from version control, reducing repository clutter for macOS contributors. The work leveraged skills in asset management, version control, and macOS development, resulting in a cleaner, more maintainable codebase. The scope was focused and technically sound, with depth in platform-specific asset handling.
