Share Your Screen: Mastering the Senior iOS Live Coding and System Design Interview
You know Swift. You have shipped real apps. And you can still bomb a live round in minute six, because knowing and performing are different skills, and almost nobody practices the second one.This is a training program for the performing half, built from real senior iOS interviews, for engineers with a loop on the calendar.What arrives in your library today The book: 555 pages, in PDF, EPUB, and DOCX. Twenty-four chapters plus a round decoder that translates vague recruiter phrases ("iOS coding exercise", "technical interview with the team") into exactly what to prepare in the last 48 hours. The problem bank: 75 fully worked interview problems across concurrency, SwiftUI, UIKit, networking, persistence, debugging, algorithms, system design, and take-homes. Every one follows the same shape: the prompt, the clarifying questions worth asking, the approach narrated the way you should say it in the room, a complete Swift solution, common mistakes, and the follow-up ladder interviewers actually climb. Every line of Swift in the bank has been compiler-checked under Swift 6 strict concurrency. Seven full mock interviews, annotated minute by minute: token refresh, system design, a live feed build, take-home review, concurrency debugging, behavioral, and code review. Each ships with an interviewer runsheet and a blank scorecard in the companion repository, so a friend can run you through a genuinely unspoiled round. Nine full-length case studies, including a real, passed senior concurrency round, annotated down to the sentences that scored. The companion repository: a Swift package of tested reference implementations you can run with swift test, nine hands-on exercises, and the mock kits. Company loop maps for Uber, DoorDash, Airbnb, Lyft, Meta, Robinhood, Instacart, and Apple, compiled from public interview reports, with the honest caveat that your recruiter is the only authoritative source. A four-week preparation plan that tells you exactly what to practice each day, and a practice workbook of checklists, worksheets, and timed drills. Current for 2026. Swift 6 strict concurrency, @Observable, SwiftUI-first with the UIKit depth interviews still demand, Swift Testing, SwiftData's honest limits, and how interviewers evaluate AI-assisted coding now.Who this is for. Mid-to-senior iOS engineers preparing for senior and staff loops. It assumes you can already build; it trains how you perform. If you are learning Swift, start elsewhere and come back.Your purchase is protectedFree lifetime updates. iOS and Swift change every year, and so does this book. Every future version, new problems, new case studies, and corrections appear in your Gumroad library free, with an email when they ship.The math, plainly. A senior iOS offer moves in tens of thousands. This costs less than one hour of the salary difference it is built to win.
