During March 2025, Daniel Szabo refactored the background playback delegate for the THEOplayer/react-native-theoplayer repository, focusing on improving internal state management within the iOS React Native integration. He transitioned the DefaultBackgroundPlaybackDelegate from a struct to a class in Swift, enabling more robust internal state handling while maintaining the existing background audio configuration for users. This change did not alter the external API but enhanced the maintainability and extensibility of the codebase. Daniel’s work demonstrated a strong command of React Native, iOS development, and Swift, laying a solid foundation for future enhancements to background playback functionality.
