Cracking the iOS Interview
A Deep, Practical Guide for iOS Developers
Most iOS interview preparation focuses on memorizing APIs or rehearsing isolated questions.
This book focuses on something interviewers care far more about: how you think, reason, and explain decisions.
Cracking the iOS Interview is written for iOS developers who already build real applications but want to perform better in mid to senior-level interviews.
What This Book Is About
This book is a practical guide to the most commonly discussed iOS interview topics — explained from the perspective of real interview conversations.
Instead of listing answers, it focuses on:
- reasoning through trade-offs
- explaining architectural decisions
- handling follow-up questions calmly
- communicating like a senior iOS engineer
From memory management and Copy-on-Write to Swift Concurrency and architecture, each chapter is designed to help you articulate why you would choose a particular approach, not just what it does.
What Makes This Book Different
- Emphasizes mental models, not memorization
- Covers follow-up questions interviewers actually ask
- Written from real production and interview experience
- No beginner tutorials or framework walkthroughs
- Focused on clarity, structure, and decision-making
From Chapter 7 onward, chapters include concise follow-up Q&A written in a spoken style, making it easier to respond naturally in live interviews.
Who This Book Is For
This book is intended for:
- iOS developers with 2+ years of experience
- Engineers preparing for mid to senior iOS roles
- Candidates who struggle to explain reasoning clearly
- Developers targeting product-based companies
If you are new to iOS or still learning Swift fundamentals, this book may not be the right fit yet.
How to Read This Book
You can read the book end-to-end or treat it as a reference while preparing for interviews.
Each chapter is self-contained and focused on a single interview-relevant concept.
The goal is not to help you “crack” one interview, but to help you build a repeatable way of thinking that scales across interviews.
