The native binaries are bundled with a regular iOS framework. To be able to access the implementations of the Shared module, the code needs to be compiled to native binaries using the Kotlin/Native compiler. The package inside the Shared module can be imported and its implementations would be available right away.įor the iOS application, the integration is different.

If the Shared module is created inside an Android application project, then the integration for Android is complete. Kotlin is a modern programming language developed by JetBrains and adopted by Google as the recommended language for Android development.

You can create it using the KMM plugin for Android Studio. The code to be shared on Android and iOS is implemented in an independent Gradle module (more specifically a Kotlin Multiplatform module) and it’s written in Kotlin. You can read more about this here: Kotlin Multiplatform use cases. This can give us cross-platform development beyond mobile. Libraries created for Common Kotlin (called Multiplatform libraries) can be used on platform-specific implementations (JVM, JS, and Native). Generates code compatible with Android and iOS.Ĭode written in Common Kotlin works everywhere on all supported platforms.Generates code for Java Virtual Machine.Here is how Koltin Multiplatform is composed: Kotlin Multiplatform is a set of libraries that allow us to program multi-platform logic in common and platform-specific code. KMM works because of the Kotlin Multiplatform technology. KMM is an SDK for Android and iOS apps that helps us create Kotlin Multiplatform modules that compile into Android libraries and iOS frameworks. It’s called Kotlin Multiplatform Mobile (KMM). I just want to mention one common constraint with hybrid solutions: it’s hard to implement in existing projects.įortunately for us, there have been some interesting developments regarding mobile cross-platform: a tool that enables us to share code between mobile platforms with native performance and easy integration in existing projects. There are some pros and cons between hybrid and native solutions but that’s not the topic of this blog post.

That’s why hybrid technologies like Flutter, React Native, and many more can be powerful tools for mobile development because they enable us to create cross-platform applications with a single codebase. Nowadays, many products are composed of an iOS and Android app, and sharing code between both platforms is crucial to save time and to avoid different behaviours.
