🖼️ Async Image Downloading (SwiftUI)

A concise, runnable SwiftUI example of loading remote images with AsyncImage.

📖 Overview

This project is a small SwiftUI learning example that demonstrates how to download and display a remote image using SwiftUI's built‑in AsyncImage view. While the image is loading, a system placeholder icon is shown; once the download completes, the image is rendered as a circular avatar. Tapping the loaded image swaps the URL, triggering a fresh download of a second image.

It follows a clean MVVM structure — the view state and image URLs live in an ObservableObject view model, keeping the views declarative and free of business logic.

✨ Features

• AsyncImage remote loading — downloads an image from a URL with a placeholder shown during loading.
• Placeholder view — an SF Symbol (person.circle.fill) rendered as a circular avatar while the image loads.
• Tap to swap image — tapping the downloaded image updates the URL via the view model to load a different image.
• MVVM separation — a ViewModel (ObservableObject) publishes the image URL and owns the image‑switching logic.
• Centralized constants — placeholder name, size, and the secondary image URL are kept in a Constants enum.
