Worked on the pointfreeco/swift-composable-architecture repository to deliver Date value support within AppStorage, enabling seamless persistence of time-based state in iOS applications. Implemented new initializers for both optional and non-optional Date types, ensuring that developers can easily store and retrieve Date values using Swift and SwiftUI. Accompanying tests were added to verify reliable integration with UserDefaults, reducing boilerplate and preventing regressions across app launches. The work focused on state management and improved code health by expanding test coverage, addressing the need for robust Date persistence without introducing new bugs, and enhancing the overall reliability of stateful SwiftUI applications.
