Simplifying Application Development With Kotlin Multiplatform Mobile

Explore the new Kotlin Multiplatform to build native apps for Android and iOS while sharing business logic between apps Key FeaturesImprove app development speed dramatically by writing the business logic in KotlinImplement a native user interface and work with platform-specific APIsLeverage Kotlin Multiplatform Mobile's code-sharing capabilities for your projectsBook 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.
