Open in Xcode (.xcodeproj or .xcworkspace).

Select a simulator or device → Run (⌘R).

Requires Xcode 13+, iOS 15+, and Swift 5+.

Pattern: MVVM (Model–View–ViewModel)

Networking: URLSession using async/await for image fetching.

Caching: Custom in-memory + disk caching for offline access.

UI: SwiftUI views with pull-to-refresh and lazy loading.

Data Flow:
View → ViewModel → Service → Model → View (updates asynchronously)

Views/           → SwiftUI Screens  
ViewModels/      → Business Logic  
Services/        → Networking + Caching  
Models/          → Data Structures  

Public API or open image URLs (no authentication).

Stable network during first fetch

Image count moderate (< 500) for smooth scrolling.

Designed primarily for iPhone, adaptive for iPad.

MVVM + async/await: Clean separation and responsive UI.

Custom cache: Avoids redundant downloads and supports offline access.

Minimal dependencies: Built using native Swift frameworks only.

Error handling: Graceful fallback with retry support.

Scalable layout: Grid adapts to device size/orientation.
