Mobile Coding Interviews: Pattern-Based Problem Solving in Swift & Kotlin is a practical, no-fluff guide to mastering coding interviews for iOS and Android developers. Instead of memorizing hundreds of problems, this book teaches you how to recognize recurring patterns and apply them confidently in Swift and Kotlin.

You’ll learn how interviews actually work, how to analyze time and space complexity quickly, and how to approach problems using a pattern-first mindset—the same approach used by top candidates at FAANG and mobile-focused companies. Each core pattern is broken down with clear recognition signals, reusable templates in both Swift and Kotlin, and carefully selected interview-favorite problems.

Covering everything from Two Pointers and Sliding Window to Graphs, Dynamic Programming, and Advanced Patterns, this book helps you build strong intuition, write clean code under pressure, and explain your thinking clearly during interviews. The final sections focus on practice strategy, pattern cheat sheets, and interview-day frameworksso you walk into interviews calm, structured, and prepared.

If you’re a mobile developer aiming to pass technical interviews by thinking in patterns—not panic—this book is your roadmap.
