Frequently Asked Questions
▶︎ Who is the target audience for the book?
- The guide is designed for aspiring iOS developers, as well as experienced developers looking to improve their interview skills or brush up on their knowledge. It is also ideal for hiring managers and interviewers who are looking for a comprehensive resource to use during the interview process.
▶︎ Do I really need this book for iOS interview preparation?
- The Uplift iOS Interview may be a valuable resource, but it is no panacea that can supplant the invaluable experience gleaned from actual iOS development. I do not wish to toot my own horn, but as a technical interviewer and hiring manager, I have invested a prodigious amount of time to curate and generate these questions and their corresponding answers. If you have the motivation and energy to search for iOS interview questions and tips online, particularly on platforms like LeetCode, Glassdoor, Indeed, Naukri, LinkedIn, Monster Jobs, iOS subreddits, and Twitter, then you probably won't need a few chapters of this guide. Rather than spending too much time searching for resources, I believe it's more worthwhile to invest your time in actual preparation. The follow-up conceptual iOS questions in this guide are an absolute game-changer when it comes to preparing topic-wise. Trust me, they'll give you the competitive edge you need to stand out from the crowd.
▶︎ Does the guide contain SwiftUI Interview Questions?
- Absolutely! The guide possesses up do date SwiftUI interview questions, all curated and crafted to challenge and inspire.
▶︎ What formats of publication are offered?
- A .pdf version of the book will be provided to you.
▶︎ Will there be any new additions or updates?
- Yes, I intend to provide ongoing support for this guide. I will continuously update it with any new interview questions related to iOS and you will have access to these updates at no extra cost.
▶︎ What are Infographics? Do they already exist on various online platforms? Do I need them? Why don't you add the infographics to the guide?
- Explanation infographics are a popular way to present information visually to help communicate complex ideas in an easy-to-understand way. By presenting the explanation in an infographic format, it can be easier for a beginner level iOS candidates to quickly review and understand key concepts and best practices.
- You may have noticed that I have shared numerous infographics from 2021 across various online platforms such as Reddit, LinkedIn, and Twitter. In case you actively follow me, you may save them each time I share them.
- While explanation infographics can aid beginner iOS developers in grasping concepts with more clarity and enable them to think critically, they may NOT be necessary for all iOS developers. Consider infographic as a "READ MORE" option for suggested answers. The guide includes precise and easy-to-understand answers to assist developers at all levels of expertise. There are certain suggested answers that require further clarification or infographics, but most of them are self-explanatory. Nevertheless, if I were to provide a one-page explanation for each of the 380+ questions in the book, it would exceed 600 pages. This could potentially be overwhelming for readers and negatively impact their reading experience.
▶︎ I am Anubhav, residing in India 🇮🇳 and proficient in iOS development with 8 years of experience. Despite applying to several US-based companies, I have yet to secure an interview opportunity. How does the Uplift iOS Interview guide help me?
- By utilizing the Uplift iOS interview guide, you can improve your interview skills, gain confidence in your abilities, and increase your chances of securing an interview. In Chapter 1, Intimidating Experience of the iOS Interview, I will describe the procedure to improve the interview performance.
▶︎ My name is Yasir, and I'm a junior iOS developer from Morocco 🇲🇦. I aspire to join a renowned company in Germany as a professional iOS developer. How should I prepare for the interview?
- To prepare for your interview as a professional iOS developer in Germany, you can use the Uplift iOS Interview as a comprehensive guide. Review the fundamentals of Swift(Chapter 3), SwiftUI(Chapter 10), and iOS frameworks(Chapter 6), practice hard questions, read other interview questions and answers, and learn from the explanations provided in the book to increase your knowledge and confidence during the interview.
▶︎ As a hiring manager, my aim is to maintain a steady stream of questions for conducting primary verbal technical interviews of Principle/Lead iOS Engineers. I'm wondering if this guide provides advanced and tricky content to evaluate their skills in a short time. - Mathias, San Jose 🇺🇸
- No, the guide doesn't have any tricky questions aimed at stumping senior/principal/lead iOS engineers. Tricky questions, in my opinion, don't add much value for either the candidate or the hiring manager, so I prefer not to promote them. Instead, I recommend asking conceptual questions that prompt follow-up questions to gauge a candidate's depth of knowledge. The guide features a range of basic to advanced conceptual questions that can provoke more in-depth discussion between the hiring manager and the candidate.
▶︎ Hello Ishtiak, I was introduced to your book by a friend of mine. I am a student at Dhaka University and while I am usually able to perform well in verbal iOS technical interviews, I struggle with coding interviews. I was wondering if your book includes coding problems in addition to interview questions? - Rony, DU, Dhaka, 🇧🇩
- Sorry to say that the current edition of my guide does NOT cover coding interviews. You see, coding interviews are a whole different ball game in the world of iOS interview preparation. In fact, I strongly believe that there's so much ground to cover when it comes to iOS coding interviews that a separate guide would be more appropriate. Though - I'll be sure to put my thinking cap on and whip up a comprehensive guide in the future.
▶︎ My name is "X" and I'm based in Bangalore Karnataka, 🇮🇳. I'm currently working for a start-up but am keen to transition to a prestigious company. I've completed the first six chapters of the book and recently attended an interview where the team lead asked me a few questions that were covered in the guide. However, I was unable to explain the concepts clearly. Where did I go wrong? Should I focus on memorizing the questions? (Using X instead of the real name upon the person's request)
- Merely memorizing the guide won't be of many benefits, as it's not a holy grail. In school, we often memorize information without truly understanding it, only to forget it later when it's time to apply the knowledge. If the question topic is unfamiliar to you, I recommend that you thoroughly investigate it. Rather than attempting to memorize the answers, I suggest that you take the time to carefully read the suggested response and ensure that you comprehend it. Once you have a basic understanding, I encourage you to explain it in your own words. This technique is an excellent way to confirm your understanding of the material and enhance your ability to communicate effectively.
Tips for Extracting Maximum Value of This Guide
- While reading the questions and suggested answers, take the time to carefully consider the alternative answer you already know and think about the information that you want to convey.
- It's better if you don't try to memorize the answers, instead, take some time to read the suggested answer carefully and make sure you understand it. Once you get the gist of it, try to explain it in your own words. It's a great way to make sure you really understand the material and can communicate it effectively.
- It’s also important to remember that these interview questions are not meant to be difficult. The interviewer is not looking to challenge you, but rather to start a conversation that will allow your abilities and interests to come to the forefront. They want to get to know you and your experience better.
- One important thing to keep in mind is to avoid giving short, one-word answers like "yes" or "no." Instead, try to provide thoughtful, detailed responses that showcase your understanding of the topic and include examples that demonstrate your skills and expertise. By doing so, you'll give the interviewer a deeper insight into your capabilities and show that you're a prepared and knowledgeable candidate.

I've also been adding new questions periodically to keep the content fresh and relevant.
