What is the role and purpose of the presentation layer in application architecture?

The View Layer in application architecture is responsible for the visual presentation of data and user interaction. Its main task is to display information received from the business logic or model and to handle user actions (clicks, gestures, etc.).

In iOS, this is usually managed by UIView and related controllers (UIViewController), which control the display and updating of the interface.

Role of the view layer:

• Separating the visual part from the application logic (to make the code more maintainable).
• Providing a responsive and understandable interface.
• Handling user input and passing events further into the architecture (for example, to Presenter or ViewModel).

Example: UIViewController receives data from the model and updates a UILabel to show the user current information.
