Share Your Screen
Senior iOS live coding and system design
Version 2026 edition · Updated 5 Aug 2026
The live round is where strong engineers freeze. This is how you do not.
You know Swift. You have shipped real apps. You can still lose a senior iOS live round in minute six because knowing and performing are different skills.
Share Your Screen trains the performing half: making your thinking visible, recovering when you stall and holding your ground under pressure.
The program covers live coding, take-home review, code review and mobile system design with current Swift 6 concurrency, SwiftUI, UIKit and Swift Testing depth.

Main description
You know the material. So why does the live round go sideways?
At senior level, the interviewer scores what they can hear. A brilliant silent solve and a confused silent solve look identical from the other chair.
Most candidates do not lose on the code. They lose when they freeze after sharing their screen, become scattered after an interruption or cannot explain the judgment behind a correct implementation.
The book reverse-engineers what interviewers write down and turns those invisible skills into a method you can rehearse in any room.
What this book helps with
Everything between the app and the system around it.

The framework
Make your thinking visible
- Clarify
- Narrate
- Build
- Recover
- Verify
A strong live-round performance makes judgment observable before the final code is complete, then turns a stall into evidence of method rather than panic.
Product proof
What you can inspect before buying.
Each book page shows the method, the scope, and the kind of transformation the material is designed to create. Real reader testimonials are only shown when genuine quotes are available.
Tested companion repository
Run the reference implementations and exercises with swift test instead of trusting code printed on a page.
Partner-practice kit
Use blank mocks, interviewer runsheets, interruption cues and scorecards for realistic rehearsal.
Free lifetime updates
Future Swift releases, new problems, case studies and corrections remain part of the purchase.

Reader reviews
What readers say
“I've bought many iOS interview books, but they're all far behind this one ☝️. What I love most is that Mike shares his real experience instead of just listing questions and answers. It's practical, easy to follow, and feels like advice from someone who's actually been through these interviews. I'm still preparing for my interviews, but this book has already changed the way I think about live coding sessions. I've always struggled with explaining my thought process while coding 😭, and this book really opened my eyes to how to approach problems, communicate my reasoning clearly, and avoid turning the session into complete chaos ❤️. Amazing resource! I highly recommend it!!!”
“Most iOS interview books stop at 'here's the answer.' This one shows you the entire conversation: the interviewer's follow-ups, where candidates stall, and what a strong recovery looks like. I ran two of the annotated mocks with a colleague before my onsite, and I got the offer.”
“I'm a solid engineer, but I used to be terrible at live coding, dealing with screen-sharing anxiety and blanking on APIs I use daily. The test-first opening strategy and the mock transcripts gave me a reliable script for the first five minutes, and momentum carried me through the rest. I signed an offer last week with a 24% compensation bump.”

I built this from work I have done across Apple, Adobe, Cisco, Mastercard and Visa, and from more than 500 interviews on the screening side. The questions engineers kept sending me were versions of the same problem: I know the material, so why do I keep failing the live round? This book is the answer.
