Developing the app required learning Swift, SwiftUI, and the Xcode environment from scratch. Understanding Swift's syntax and structure while adapting to SwiftUI’s declarative UI approach was a significant challenge. Designing app menus, creating responsive layouts, and implementing interactive elements like swipe gestures and navigation transitions required extensive experimentation.

Connecting the front-end UI to the back-end logic using data bindings and state management posed additional hurdles, as SwiftUI handles UI updates differently than traditional imperative frameworks. Debugging and optimizing performance in Xcode, especially for older devices, also required learning to use profiling tools like Instruments. Overall, mastering SwiftUI and Xcode while ensuring a seamless user experience on outdated hardware was both a technical and learning-intensive challenge.
