iOS App Template with Clean Architecture and MVVM

This is a template iOS application built using Clean Architecture and MVVM principles, utilizing SwiftUI and Combine. The project includes DIContainer, FlowCoordinator, DTO, Response Caching, and more.

Features

  • Clean Architecture and MVVM Design
  • SwiftUI for UI Components
  • Combine for Reactive Programming
  • Dependency Injection
  • Network Layer with Alamofire
  • Unit Testing with XCTest
  • Mock Implementations for Testing

Detailed Explanation

Presentation Layer

Views:

  • UserView: Displays a list of users with an interactive UI, utilizing SwiftUI's NavigationView, List, and ProgressView.
  • UserDetailView: Shows detailed information about a selected user, enhanced with attractive typography and layout elements.

ViewModels:

  • UserViewModel: Manages UI state, fetches user data through the FetchUsersUseCase, and handles user interactions, updating the view accordingly. Utilizes Combine to reactively bind data changes.

Domain Layer

Protocols:

  • UserFetchDelegate: Defines contracts for operations, ensuring communication between layers without specific implementation details. Use Cases:

  • FetchUsersUseCase: Encapsulates the business logic for fetching users, interacting with repositories to obtain data. Entities:

  • User: Represents core business objects with properties id, name, and email. Repositories:

  • UserRepository: Defines interfaces for data operations, abstracting data access from the Domain Layer.

Data Layer

Network:

  • APIService: Handles network requests using Alamofire, providing a generic method for making API calls and managing network errors. Repositories:

  • UserRepositoryImpl: Implements the UserRepository interface, fetching data from the network and mapping it to domain entities using DTOs.
