Technology Stack

• SwiftUI for the UI
• Minimum iOS target: 18.0
• Clean Architecture with MVVM presentation pattern
• Swinject for dependency injection
• Google Books API for data
• Localization support (English and Czech)
• Custom app icon and book icons created with Adobe Fresco and Adobe Illustrator

Project Structure

The project follows Clean Architecture principles, organized into the following layers:

Presentation

• Book
  • Views (BookCellView, BookDetailView, BookListView, etc.)
  • ViewModels

Domain

• Book
  • Entity (Book.swift)
  • UseCase (GetBooksUseCase)

Data

• Volume
  • DataSource
    • VolumeDataSource interfaces and implementations (Mock, Remote)
  • DTO
    • Data transfer objects for Book/Volume data

Core

• Assembly - Dependency registration
• Extensions - Utility extensions
• Network - HTTP client implementation
• Protocols - Shared interfaces

Configuration

• Config.xcconfig - Contains BOOK API URL

Architecture Overview

The application is built using Clean Architecture principles, which separates concerns into distinct layers:

1. Presentation Layer: Contains UI components (views) and view models
2. Domain Layer: Contains business logic, use cases, and domain entities
3. Data Layer: Handles data operations and external API communication

The Repository layer was intentionally omitted (YAGNI principle).

Navigation

The app uses the new SwiftUI navigationTransition(.zoom) for transitions between screens.

Setup & Installation

1. Clone the repository
2. Open the project in Xcode
3. Build and run the application

Testing

The project includes unit tests for the GetBooks use case. Run tests using Xcode's testing framework.

Development Time

1 MD

Requirements

• iOS 18.0+
• Xcode 16.0+
• Swift 5.9+

Future Improvements

• Add more filtering options beyond author name
• Implement caching for offline use
• Add pagination for large result sets

Notes

This project was developed as a coding task for an interview process. It demonstrates clean code structure, modern iOS development practices, and effective use of the Google Books API.
