Worked on the apple/container repository to enhance the reliability of terminal interactions within the ProgressBar extension. Focused on debugging and code hygiene, the primary contribution involved fixing a typo and improving variable naming, which strengthened terminal handling and reduced the risk of confusion or failure during progress display. This update, implemented in Swift for iOS development, improved maintainability and set a foundation for future enhancements. By addressing a critical bug rather than adding new features, the work contributed to more robust developer workflows and automated pipelines, demonstrating attention to detail and a methodical approach to code quality and long-term project stability.
