Simplifying Application Development with Kotlin Multiplatform Mobile

By: Róbert Nagy

Overview of this book

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.

Chapter 7: Writing an iOS Consumer App

After trying out the shared code on Android, the next step will be doing the same for iOS. Spoiler alert—it won't be exactly as seamless as on Android, and we'll need to make some adaptations to the shared code. For this reason, I believe this chapter should offer a good insight into what extra work is actually needed for making Kotlin Multiplatform (KMP) shared code work on iOS and how seamless it can be with the current tech stack on Swift. This chapter will follow a similar structure to Chapter 6, Writing the Android Consumer App, and in it, we will explore the following topics:

  • Setting up the iOS app
  • Tying the iOS app together with the shared code
  • Implementing the UI on iOS
