What are the main difficulties and disadvantages you can highlight in MVC architecture?

Main challenges and disadvantages of the MVC (Model-View-Controller) architecture in iOS:

• Massive View Controller: Controllers often become too large and complex, as they concentrate the logic of interacting with the model and updating the view.
• Weak separation of responsibilities: Due to the close connection between View and Controller, it is difficult to reuse components and test logic separately.
• Scaling difficulties: As the application grows and logic becomes more complex, controllers become hard to maintain.
• Connection between View and Controller: View often depends on Controller, which reduces flexibility and complicates interface changes.

To mitigate these issues, patterns like MVVM, VIPER are often used, or delegates and services are employed to separate logic.
