Informational App with Review System

I need a clean, fast iOS application that showcases product information and lets users leave a simple star-based rating for each item. My priority is a smooth, native experience built with Swift (SwiftUI is perfectly fine) that fits Apple’s current Human Interface Guidelines.

Core flow
• Browse or search products.
• Tap to open a detail screen that presents the description, key specs and images I will provide through a JSON feed or lightweight API.
• From that screen users can leave a star rating (1–5). No text or photo uploads are required.
• The average rating updates instantly and is stored so it remains consistent across devices.

What I will hand over
• The product data source in JSON.
• Brand colours, basic icon set and fonts.

What I expect back
• Xcode project that compiles on the latest stable Xcode.
• Well-commented Swift code and a brief README explaining any third-party libraries you chose to pull in (if any).
• A TestFlight-ready build so I can try it on my devices.

When the build passes basic UI tests (navigation, rating persistency and data load), we’re done.
