What factors do you consider when choosing an architectural solution?

When choosing an architectural solution for an iOS application, it is important to consider several key factors:

• Project requirements: functionality, scalability, performance requirements.
• Maintainability and extensibility: how easily new features can be added and the code maintained.
• Team and experience: the level of knowledge and experience of developers with specific architectural patterns (MVC, MVVM, VIPER, etc.).
• Testability: the ability to write unit and integration tests.
• Performance: the impact of architecture on the application's speed and resource consumption.
• Implementation complexity: balancing architectural strictness and simplicity.
• Interaction with other components: such as network, database, UI.

For example, a small application might be sufficiently served by MVC, while a larger one should consider MVVM or VIPER for better modularity and testability.
