iOS E-Commerce App Development

I want to launch a full-featured e-commerce experience exclusively on iOS. The app should let shoppers browse products, add items to a cart, pay securely, and track orders—all within a clean, modern SwiftUI interface that meets Apple’s latest Human Interface Guidelines.

Core expectations
• Native Swift / SwiftUI codebase compiled in Xcode
• Seamless catalogue, search, cart, checkout, and order-history flows
• Secure payment gateway integration (Apple Pay preferred but I’m open to suggestions)
• Basic admin endpoints or JSON stubs so catalogue and inventory can be updated later
• TestFlight-ready build plus complete source code and build instructions

Acceptance criteria
1. App installs and runs on iOS 17 without crashes.
2. End-to-end checkout works with a sandbox payment account.
3. UI matches supplied wireframes (or your proposed design after approval).
4. All major user flows covered by unit or UI tests.

Hand-off deliverables will include the Xcode project, asset files, and a brief README outlining any setup steps.
