Modern App Development with Kotlin 2.3 and KMP: Guide to Building Scalable Cross-Platform Apps for Android and iOS

Are you looking for a practical way to build high-quality mobile apps without maintaining separate codebases for different platforms? Do you want a development approach that reduces duplication, improves maintainability, and scales with real-world demands?

Modern App Development with Kotlin 2.3 and KMP is written to answer those exact questions. This book presents a clear, hands-on path to building robust cross-platform applications using a shared code strategy while still respecting the strengths of each platform. It focuses on writing reusable business logic once and integrating it seamlessly into both Android and iOS applications.

You will learn how to structure scalable projects, organize shared modules effectively, and apply modern architectural patterns that hold up in production environments. The book goes beyond basic syntax and explores how to manage concurrency, handle data serialization, implement networking layers, and design efficient persistence systems that work consistently across platforms.

Curious about performance? You will see how to optimize memory usage, manage background tasks, and ensure smooth UI interactions even in data-heavy applications. Concerned about real-world challenges? The included projects—such as a task manager, social feed, and e-commerce system—demonstrate how shared logic interacts with platform-specific interfaces in practical scenarios.

This guide is designed for developers who want more than theory. It provides a structured, experience-driven approach to building scalable applications while preparing you for future advancements in multiplatform development.

If your goal is to build smarter, maintain less code, and deliver consistent user experiences across platforms, this book gives you a solid, professional foundation to do exactly that.
