What are the main functions performed by the Router component in applications or systems?

The Router component in applications, especially in iOS, is responsible for navigation between screens or modules of the application. Its main functions:

• Managing transitions between screens (ViewControllers).
• Encapsulating navigation logic to separate it from business logic and UI.
• Creating and configuring screens before display.
• Ensuring routing based on the application's state or user actions.

For example, the Router can decide which screen to show after a successful user login and perform transitions with animation. This helps make the code more modular and testable, as navigation is centralized and not scattered across different parts of the application.
