KMM helps mobile teams share code between Android and iOS in a flexible way, leaving room for native development. 14 | 15 | This book covers the following exciting features: 16 | * Get acquainted with the multiplatform approach and KMM's competitive edge 17 | * Understand how Kotlin Multiplatform works under the hood 18 | * Get up and running with the Kotlin language quickly in the context of Swift 19 | * Find out how to share code between Android and iOS 20 | * Explore tips and best practices in KMM to increase app development efficiency 21 | * Discover adoption tips to integrate KMM into existing or new production apps 22 | 23 | If you feel this book is for you, get your [copy](https://www.amazon.com/Simplifying-Application-Development-Kotlin-Multiplatform/dp/1801812586) today! 24 | 25 | 26 | ## Instructions and Navigations 27 | All of the code is organized into folders. For example, Chapter05. 28 | 29 | The code will look like the following: 30 | ``` 31 | android { 32 | compileSdkVersion(30) 33 | sourceSets["main"].manifest.srcFile 34 | ("src/androidMain/AndroidManifest.xml") 35 | defaultConfig { 36 | minSdkVersion(23) 37 | targetSdkVersion(30) 38 | } 39 | } 40 | ``` 41 | 42 | **Following is what you need for this book:** 43 | 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. 44 | 45 | With the following software and hardware list you can run all code files present in the book (Chapter 1-10). 46 | 47 | ### Software and Hardware List 48 | | Chapter | Software/Hardware required | OS required | 49 | | -------- | ------------------------------------ | ----------------------------------- | 50 | | 1-10 | Android Studio Artic Fox | Windows, Mac OS X, and Linux | 51 | | 1-10 | Android Studio KMM Plugin| Windows, Mac OS X, and Linux | 52 | 53 | 54 | We also provide a PDF file that has color images of the screenshots/diagrams used in this book.
