Have you encountered the development and design of software system architectures?

Yes, I have participated in designing the architecture of software systems, especially in the context of iOS applications. This includes choosing an architectural pattern (MVC, MVVM, VIPER), dividing responsibilities among components, as well as ensuring scalability and testability.

For example, when developing a large application, I used MVVM to separate business logic from the UI, which simplified maintenance and the addition of new features. It is also important to consider network interaction, data storage, and error handling to make the architecture robust and scalable.
