Worked on stabilizing the tabbed window workflow for the ghostty-org/ghostty macOS application, focusing on reducing crashes and improving user experience. Addressed a specific crash that occurred when adding a tab from the tab overview by introducing an Objective-C exception catcher around the tab insertion logic. This defensive programming approach ensured that unhandled exceptions in the tab path were gracefully managed, enhancing the stability and maintainability of the tabbed UI. Utilized Objective-C and Swift to implement robust error handling and crash resilience, resulting in a smoother user experience and a more reliable macOS application without introducing new features during this period.
