SwiftUI Image Loader

This is a SwiftUI application for iOS to efficiently load and display images in a scrollable grid. It shows a 3-column square image grid. The images are center cropped and are lazily loaded using disk and memory caching mechanisms to ensure smooth scrolling performance

Features

• Image Grid: Show a 3-column square image grid. The images should be centercropped.
• Image Loading: Asynchronous image loading.
• Display: Ability to scroll through at least 100 images.
• Caching: Caching mechanism to store images retrieved from the API in both memory and disk cache for efficient retrieval.
• Error Handling: Handling of network errors and image loading failures gracefully, providing informative error messages and placeholders for failed image loads.
• Once user scrolls quickly, the image loading of non-visible grid items is cancelled and loading for the visible grid items is resumed.

• Pagination can be added once the API supports it.
