Worked on enhancing the reliability and maintainability of FormSheet flows within the software-mansion/react-native-screens repository, focusing on iOS development using React Native and Objective-C. Addressed a UI clipping issue by synchronously removing the FormSheet scroll view KVO observer during the teardown process, which prevented race conditions and improved modal lifecycle management. Added a regression test in TypeScript to validate correct behavior when dismissing a FormSheet and immediately pushing a new ScrollView, ensuring robust teardown and rendering. Maintained clear commit messaging and issue traceability, supporting future maintenance and code hygiene while prioritizing user experience and stability across iOS flows.
