What readers say
“It's a very good book that many core concepts have been covered and I feel this is some high level expert book. I strongly prefer to buy this and upgrade the skills and I do feel we can cover some basics things also. Overall an excellent book.”
“The iOS Interview Handbook was an invaluable resource during my preparation. It provided clear and concise explanations of key topics, along with practical examples that helped me reinforce my understanding. The structured format made it easy to focus on the most important areas, and the real-world examples helped me approach questions with confidence. I highly recommend this book to anyone preparing for iOS interviews!”
“The book holds very important topics to not only prepare for interviews but to learn as well. Along with basics there are other topics which are really important as part of development which we as dev follow less during our day to day activities. So one can follow it easily and implement it too.”
“Very well curated list by topics sections. Initially I was skeptical about not having the answers but later I realised that's the best way to prepare and compile the answers. I would definitely recommend to go ahead. I'm happy to see answers of all questions in the latest version.”
