Goal: Setup a Kotlin Multiplatform library which targets iOS and Android (specifically) which you can test on Simulator/Emulator and in your machine’s JVM (by mocking of course). This post is about doing just that with minimal configuration.

The official KMP docs on Android Libraries are only good if you know how KMP projects work in detail (for example source sets and compilations configuration and so on) which may not be beginner friendly. For all my ongoing work, check out this repo Įvery tutorial or documentation I found online is about JVM and iOS. I have been working with KMP a lot recently. It’s effectively used as a buzzword, one that major corporations including Microsoft use, but Google explicitly does not call Java or Kotlin native, to them only NDK code is native.How to set up Kotlin multiplatform library for Android and iOS

Recruiters and marketing staff often call mobile apps written using the official Android SDK native but this is not correct - but it’s accepted as the alternative is trying to explain the difference. Native does not mean “intended framework” or “intended language.” Native means running directly on the hardware without interpreted instructions or virtual machines.Īndroid apps written in Java are not native - hence why the C/C++ tools are called the NDK, Native Development Kit.

Not only is it native, you can disable the Kotlin standard library if you really wanted and still build an application for iOS, you’ll just lose most Kotlin features because fun fact, a LOT of Kotlin is written in Kotlin. Kotlin Native compiles to the same machine code that Swift, Obj-C, C and C++ do.
