Essential iOS Interview Questions

267 interview prompts spanning the topics iOS interviews keep returning to: Swift fundamentals, design patterns, SOLID, dependency injection, architecture, memory management, networking, concurrency, Core Data, Combine, SwiftUI, testing, and release mechanics. Use it as a drill sheet — pick a section, explain each prompt out loud, and mark what you can already teach under pressure.
