Architecture Overview

This project follows Clean Architecture principles, divided into three main layers:

Core Layer

Contains business logic and domain entities

• Entities: Business models
• UseCases: Business logic operations
• Repositories: Interfaces for data operations

Data Layer

Implements data access and storage

• Network: API communication
• Persistence: Local storage (CoreData)
• DataRepositories: Implementation of Core repositories

Presentation Layer

Handles UI and user interaction

• Views: SwiftUI views
• ViewModels: Presentation logic and state management
• Composables: Reusable UI components

Benefits of this Architecture

• Separation of Concerns: Each layer has a specific responsibility
• Testability: Business logic can be tested independently of UI or external dependencies
• Maintainability: Easier to update or replace components without affecting the entire application
• Scalability: New features can be added without modifying existing code

Dependencies

• SwiftUI for UI
• Combine for reactive programming
• CoreData for local persistence

Getting Started

1. Clone the repository
2. Open MyApp.xcodeproj
3. Build and run the project
