Developed and integrated a new cookies retrieval API for Tauri webviews, enabling developers to access all cookies or those for a specific URL, with updates to runtime libraries and documentation to support cross-platform use. Addressed a race condition in macOS WKWebView cookie retrieval within the tauri-apps/wry repository by replacing synchronous waits with a robust timeout and improved event loop processing, enhancing reliability and stability. Focused on API design, concurrency, and Rust to ensure seamless webview integration and better debugging capabilities. The work emphasized cross-platform stability, particularly mitigating potential deadlocks on Windows and improving developer visibility into webview state.
