Overview

This application is developed for iOS to efficiently load and display images in a scrollable grid using the Unsplash API. The app implements asynchronous image loading, caching mechanism for efficient retrieval, and effective error handling for network errors and image loading failures.

Requirements

• Xcode (latest version)
• iOS device or simulator
• Internet connection

Installation

1. Clone the repository from GitHub:

• git clone https://github.com/kgourav46/Image-Loading-Assignment.git

2. Open the project in Xcode:

• cd Image-Loading-Assignment
• open Image Loading Assignment.xcodeproj

3. Build and run the project in Xcode.

Usage

• Upon launching the application, you'll see a scrollable grid of images loaded from the Unsplash API.
• Scroll through the grid to view more images.
• Images are loaded asynchronously and cached for efficient retrieval.
• If there's a network error, the app will gracefully handle it by providing informative error messages.

Implementation Details

• The application is implemented in Swift.
• Asynchronous image loading is implemented without using any third-party libraries.
• Images retrieved from the Unsplash API are cached in memory and/or disk cache for efficient retrieval.
• Effective error handling is implemented to handle network errors.
