MVVM-C Architecture in iOS

This repository demonstrates the implementation of the MVVM-C (Model-View-ViewModel-Coordinator) architecture in iOS applications. MVVM-C enhances the traditional MVVM pattern by introducing Coordinators, which handle navigation and flow between screens.

Architecture Overview

• View: Handles UI components.
• ViewModel: Mediates between View and Model, providing data for the UI.
• Coordinator: Manages navigation flow, decoupling ViewControllers from handling transitions.

Setting Up a Module

1. Coordinator: The Coordinator handles navigation and manages the creation of the ViewModel and View (ViewController). It controls transitions between screens and is responsible for starting and coordinating flows.
2. Create ViewModel: Implement the business logic adhering to ViewModelProtocol. The ViewModel processes data and prepares it for the View.
3. Create View: Build your UI in a UIViewController. The Coordinator injects the ViewModel into the View to handle data presentation and UI updates.

Usage

• Coordinators instantiate ViewModels and ViewControllers.
• ViewControllers bind to ViewModels for data presentation.
• Coordinators handle navigation actions triggered by the ViewModel.

Example Flow:

1. Coordinator starts a flow by creating a ViewController and ViewModel.
2. ViewModel provides data to the ViewController.
3. The user interacts with the View, and actions are sent to the ViewModel.
4. The Coordinator responds to navigation events, managing transitions between screens.

Benefits

• Separation of Concerns: Each component has a clear responsibility.
• Testability: ViewModel and business logic are easily testable.
• Scalability: Coordinators simplify complex navigation flows, improving code maintainability.

Project Structure

• View: Contains the UI components.
• ViewModel: Exposes data for the view and handles the state.
• Coordinator: Manages navigation and transitions between views.
