This app allows the user to search keywords to query image albums from the imgur api.

Upon selecting an image album, the user will be able to see all of the images for that album. The user will also be able to view these images full-screen where they can pinch/zoom.

Setup

To run the app, you'll need to add a Secrets.plist file to the root of the project with your imgur client id:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>ImgurClientId</key>
	<string>YOUR_IMGUR_CLIENT_ID</string>
</dict>
</plist>

Architecture

I created the app using MVVM for a few reasons:

1. Separation of Concerns: MVVM distinctly separates the business logic (ViewModel) from the UI (View) and data management (Model), which makes the code easier to manage and less prone to bugs
2. Reusability: The ViewModel can be reused across different views, making it easier to maintain consistency throughout the app.
3. Reactive: MVVM works seamlessly with SwiftUI’s reactive nature (e.g ObservableObject), where the UI automatically updates in response to changes in the ViewModel’s state. This reduces the complexity of managing UI state manually

Libraries

Kingfisher

Kingfisher is a powerful library that simplifies the process for fetching remote images. Here's why I chose it

1. Asynchronous Loading: Kingfisher loads images asynchronously, ensuring the UI remains responsive even when dealing with large or numerous images.

2. Performance: Image processing (e.g Downsampling, Resizing); crucial for perfomrance when loading multiple images in a listview

3. Efficient Caching: Reduces network requests and speeds up image retrieval

4. Integrates seamlessly with SwiftUI
