Problem Statement
What are common architectural anti-patterns in Swift iOS apps (e.g., Massive View Controllers, Tight Coupling, God Objects) and how would you refactor them to more maintainable architectures?
Explanation
Common anti-patterns in Swift apps include Massive View Controllers (controllers that do both UI and business logic), Tight Coupling (classes deeply dependent on each other), God Objects (single objects doing too much). /n/n To refactor: extract business logic into ViewModels or Interactors, apply Dependency Injection to reduce coupling, implement Coordinator pattern to handle navigation, break modules into smaller features, adopt Clean Architecture layering to separate concerns. Explaining this shows you understand not just good patterns but also how to avoid bad design.
