Problem Statement
Discuss trade-offs when applying design patterns and architectural patterns in Swift (e.g., simplicity vs boilerplate, flexibility vs performance) and how you balance them in real-world projects.
Explanation
Design patterns and architectures provide structure, modularity and reuse but come with trade-offs. /n/n Adding many layers (Clean Architecture) improves testability and modularity but increases boilerplate, slows initial development and may over-engineer simple features. Heavy use of patterns can reduce clarity if misapplied. /n/n In real-world Swift projects you balance by applying simpler patterns for small modules and reserving heavy architectures for complex or long-lived modules. Always favour readability, maintainability and team familiarity. Explaining this in interview shows practical judgement beyond textbooks.
