Focus Areas:

• MVVM architecture - Clear separation of logic and UI.
• Caching - fetch from the disk instead calling network
• Functional changes - Implemented a modular design with reusable components for scalability.
• Unit Testing – Ensured code reliability through test coverage.

Time spent on this project

Spent approx 4-5 hours

• Architecture and design ~ 1 hr
• Caching & networking ~ 1 - 1.5 hr
• UI ~ 1hr
• Unit testing ~1hr
• Documentation ~0.5hr

Trade-offs and Decisions:

• Used only disk caching and no in-memory caching to keep it minimal
• Used three JSON files to toggle between success, malformed, and empty states depending on the user settings.
• Although originally designed as a single-page app, added tab navigation for better organization.
• Included a Settings page to manage developer options, such as switching response types and clearing image caches.

What could be improved?

• Unreliable cache directory: I used cache directory which can be cleared by the system during low storage which makes it unreliable for long-term storage. Also could have used in-memory cache NSCache for fast access.
• No cache invalidation: There is no cache invalidation logic if images gets updated, the cached version would continue to use the outdated data unless cleared cached from Settings. It would be
• Better UI for detail page
