Multi-layer architecture is a software design pattern that divides a software application into distinct layers, each with a specific purpose. The main goal of this architecture is to improve code organization, separation of concerns, reusability, collaboration, testing, and scalability.

Each layer in a multi-layer architecture is designed to be self-contained and have a specific purpose, making it easier to understand and maintain the application. The layers are typically connected, with each layer interacting with the layers below it. This architecture promotes modularity, meaning that different parts of the app can be developed independently and then combined together.

Multi-layer iOS architecture:

1. User interface (UI) layer: This layer is responsible for presenting the user interface to the user and handling user input. It contains mainly UI-related code and no other logic. This layer can be implemented using the Model-View-Controller (MVC), Model-View-ViewModel (MVVM), or VIPER architecture.
2. Business logic layer: This layer contains the business logic of the application, such as data validation and calculations. This layer should contain classes…
