Cracking the iOS Interview — Platform Round

About the book

Most iOS interview prep focuses on memorizing APIs. This book focuses on how strong iOS engineers think, reason, debug, and communicate in real platform conversations.

Written by engineers at Expedia and Google, it covers Swift internals, concurrency, architecture, networking, SwiftUI, and interview strategy — with follow-up questions that separate a correct answer from a strong one.

What you'll learn

• Move beyond basic Swift questions into senior-level platform discussions
• Answer follow-ups with confidence instead of freezing after the first reply
• Explain trade-offs clearly under interview pressure
• Handle concurrency, performance, and debugging conversations with structure
• Think out loud the way interviewers expect from strong candidates

What this book is

A senior-level interview preparation guide for iOS developers who already know the basics and need to sound calm, confident, and senior when the conversation goes deeper. Each topic is framed around real interview questions, common misconceptions, and the mental models experienced engineers use — with spoken-style follow-up answers from Chapter 7 onward.

Who it is for

• iOS developers who have already built real applications
• Engineers preparing for mid to senior roles at product companies
• Candidates who know concepts but struggle to explain them clearly
• Anyone who freezes on follow-up questions

What makes it different

• Focuses on thinking and reasoning, not memorization
• Explains why, not just what
• Written from real production experience
• No fluff, no filler, no buzzword dumping
