XFLegoVIPER is a powerful framework that enables you to develop iOS applications using the VIPER architecture. It offers a comprehensive set of tools, along with a set of conventions, that help you build modular and scalable applications quickly and efficiently. In this guide, we will dive deep into the features and usage of XFLegoVIPER.

Getting Started

To start using XFLegoVIPER in your project, follow the steps below:

Step 1: Installation

Begin by installing XFLegoVIPER through CocoaPods. Open your project’s Podfile and add the following line:

pod 'XFLegoVIPER'

Step 2: Set up the Project Structure

Once XFLegoVIPER is installed, you need to set up the project structure in accordance with the VIPER architecture. Define separate modules for each feature or screen in your application. Within each module, create separate folders for each component of VIPER, namely View, Interactor, Presenter, Entity, and Routing.

Step 3: Create Module using XFLegoVIPER

Use XFLegoVIPER’s command-line tool to generate the necessary files for a new module. Open your terminal and navigate to your project’s directory. Execute the following command:

lego vipergen ModuleName

Replace ‘ModuleName’ with the desired name for your module. This command generates the required VIPER components and their respective files in the appropriate folders.

Step 4: Implementing VIPER Components

Once the module is created, you need to implement the VIPER components and their responsibilities as follows:

  • View: Define the user interface and handle user interactions.
  • Interactor: Handles business logic and data processing.
  • Presenter: Mediates communication between the View and the Interactor.
  • Entity: Represents the data model used within the module.
  • Routing: Handles navigation and flow between modules.

Advanced Features

Feature 1: Dependency Injection

XFLegoVIPER provides built-in support for dependency injection, allowing you to inject dependencies into each VIPER component easily. This helps improve testability, code reusability, and maintainability. You can use any dependency injection framework of your choice or rely on the default implementation provided by XFLegoVIPER.

Feature 2: Modularization

With XFLegoVIPER, you can modularize your application by dividing it into multiple independent modules. Each module follows the VIPER pattern and can be developed and tested individually, leading to a more flexible and maintainable codebase. The modules can communicate with each other through defined interfaces and data models.

Feature 3: Code Generation

XFLegoVIPER allows you to generate commonly used code snippets automatically. This saves development time by eliminating the need to write boilerplate code manually. Use the provided CLI tool to generate components such as protocols, data models, and builder classes effortlessly.
