Worked on the google-ai-edge/mediapipe-samples repository to enhance chat functionality by implementing rich text and mathematical notation rendering. Developed Markdown support for chat messages using AttributedString in SwiftUI, incorporating robust error handling to ensure stability and maintainability. Integrated LaTeX math rendering by adding the LaTeXSwiftUI library, updating dependency management, and extending the conversation view to parse and display complex mathematical expressions. These features improved the clarity and expressiveness of user conversations, supporting technical communication needs. The work focused on iOS development with Swift and Objective-C, laying a foundation for future rich-text enhancements and improved user experience.
