What is Kotlin Multiplatform Mobile (KMM)? For more details like why Kotlin replacing Java, you can read here. As you know smart phones come up with limited resources. Java is not going anywhere, but its not best fit for Android Apps, since Java was created when there was no idea of Smart Phones. Since, in Kotlin you don’t need to write boilerplate code like you do in Java. Kotlin almost replaced Java in Android Development, most of the apps nowadays are built in Kotlin. Since then it has come a long way to ease out the development in Android. In the following example, we’ve defined a Platform object which will need to be defined for each target platform.Kotlin has been one of the most talked about languages since its birth in 2011. Using expect, you add your class/property/etc declaration to your shared module. These platform specific implementations work using the expect and actual keywords. Sharing Code Between Different Build Targets These concrete implementations exist within the specific platform modules, and are then consumed by the native Android and iOS apps as if they were any other module. You might define a common declaration in common code, and then provide a platform specific implementation for both Android and iOS. Imagine you are building an Android and an iOS app. That module is included in your platform-specific projects, and consumed as if it was any other third-party library. Building For Multiple Targetsīusiness logic, data objects, interfaces, repositories, etc can all be defined within a common module. So what exactly is Kotlin Multiplatform? A Kotlin Multiplatform (KMP) project enables the sharing of common code across your various build targets. And while the technology is still rapidly evolving, it’s quickly reaching the point of viability beyond the early adopter audience. Kotlin Multiplatform makes this possible.
