🎯 Target iOS Case Study

This is a reimagined iOS application based on a legacy proof-of-concept project initially created to explore Target's mobile deals experience. The app has been rebuilt to be a scalable, production-ready showcase of Target's current deals, with a modern architecture and polished UI.

📱 Features

• Displays a list of active Target deals fetched from a remote API.
• Tappable deal items navigate to a detail screen with expanded deal information.
• Matches the provided design mocks in layout, font, and color as closely as possible.
• Fully built using UIKit for the list screen as per requirement, and extensible to include SwiftUI in the future.

🛠 Architecture & Approach

This project is built with an emphasis on:

• Clean architecture using separation of concerns (View, ViewModel, Network, Model)
• Testability via dependency injection and mockable components
• Scalability for feature expansion and codebase growth
• Reusability of UI components and services
• Robust networking layer with error handling and fallback logic
• Responsiveness across different device sizes

📡 API Integration

Live deal data is fetched from Target’s public API:

• Deals List Endpoint
  https://api.target.com/mobile_case_study_deals/v1/deals

• Deal Details Endpoint
  https://api.target.com/mobile_case_study_deals/v1/deals/{productId}
  Example: https://api.target.com/mobile_case_study_deals/v1/deals/1

🎨 UI/UX

Follows the Target case study Figma mockups, including:

• Consistent typography and spacing
• Clean card-based layout for deals
• Button styling and asset usage aligned with Target branding

⚙️ Technologies Used

• UIKit – Core UI implementation
• URLSession – Networking
• Codable – Model decoding
• Programmatic UI – No Storyboards
• Auto Layout – Responsive sizing
• Image Caching – Custom caching logic or third-party if used

🧪 Testing

• Unit tests for networking and parsing logic
• UI-level validations for layout integrity

✅ Requirements Covered

• ✅ Redesigned list view matching the mock
• ✅ Detail view upon tapping an item
• ✅ API integration using both endpoints
• ✅ UIKit implementation for list screen
• ✅ Clean, testable, maintainable code

💡 Engineering Focus Areas

• 🔸 Clean Code: Small, focused classes and methods
• 🔸 Modern Patterns: Programmatic views, MVVM-lite
• 🔸 Networking: Abstracted client with error handling
• 🔸 Error Resilience: Graceful fallback and UI recovery
• 🔸 Scalability: Easily extendable architecture
• 🔸 Accessibility: Dynamic type and semantic UI elements

📝 Notes

• The app does not use storyboards.
• Auto Layout is fully respected for responsiveness.
