  iOS Technical Interview Q&A Guide Architecture Patterns CLEAN Architecture Q: What is CLEAN Architecture? A: CLEAN Architecture is a software design philosophy created by Robert C. Martin that separates an application into layers with clear boundaries. The core principle is that dependencies point inward - outer layers depend on inner layers, never the reverse. Q: What are the layers in CLEAN Architecture? A: From innermost to outermost: Entities : Core business objects and logic Use Cases/Interactors : Application-specific business rules Interface Adapters : Presenters, ViewModels, Controllers Frameworks & Drivers : UI, Database, Network, External APIs Q: Why use CLEAN Architecture? A: Benefits include testability (mock dependencies easily), maintainability (clear separation), flexibility (swap implementations), and independence from frameworks. It's ideal for large, complex applications with multiple developers. Q: What are the disadvantages of CLEAN Arch...

  Complete iOS Interview Guide - Part 1 1. CLEAN Architecture CLEAN Architecture is a software design philosophy that emphasizes separation of concerns and independence of frameworks, UI, and databases. Created by Robert C. Martin (Uncle Bob), it's widely used in iOS development. Core Principles 1. Independence: Independent of frameworks (UIKit, SwiftUI) Independent of UI Independent of database Independent of external agencies Testable without UI, database, or external elements 2. Separation of Concerns: Each layer has a specific responsibility and doesn't know about layers above it.
