Implement a native user interface and work with platform-specific APIs
Leverage Kotlin Multiplatform Mobile's code-sharing capabilities for your projects

Book Description

Sharing code between platforms can help  developers gain a competitive edge, and Kotlin Multiplatform Mobile  (KMM) offers a sensible way to do it. KMM helps mobile teams share code  between Android and iOS in a flexible way, leaving room for native  development.

The book begins by helping you to gain a  clear understanding of the Kotlin Multiplatform approach, how it works,  and how it is different from cross-platform technologies, such as React  Native and Flutter, and code sharing options, such as C++. You'll then  see how your team can use this software development kit (SDK) to build  native applications more effectively by learning timeless concepts and  working through practical examples. As you advance, you'll get to grips  with the core concepts, understand why UI sharing fails, and get  hands-on with developing a small KMM application. Finally, you'll  discover expert tips and best practices, along with production- and  adoption-related questions, that will help you take the next step in  your project and career.

By the end of this Kotlin book, you'll  have gained a solid understanding of the capabilities of KMM and be able  to share code between Android and iOS flexibly.

What you will learn

Get acquainted with the multiplatform approach and KMM's competitive edge
Understand how Kotlin Multiplatform works under the hood
Get up and running with the Kotlin language quickly in the context of Swift
Find out how to share code between Android and iOS
Explore tips and best practices in KMM to increase app development efficiency

Who this book is for

This book is for native Android and iOS  developers who want to build high-quality apps using an efficient  development process. Knowledge of the framework and the languages used  is necessary, that is, Android with Java or Kotlin and iOS with  Objective-C or Swift. For Swift developers, the book assumes no  knowledge of Kotlin as this will be covered in the context of Swift.
