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. The company has set up a KMM developer portal and published a guide on integrating KMM into existing projects.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. With the plug-in, developers do not need to switch IDEs and have Apple’s Xcode running to ensure that code works properly on both platforms.Ĭompanies already have saved time and effort sharing code between platforms, such as Quizlet and Fastwork, JetBrains said. Thus, KMM business modules can be used like any other mobile library. Shared code written in Kotlin is compiled to JVM bytecode with Kotlin/JVM and to native binaries via Kotlin/Native. A single codebase can be used for business logic while platform-specific logic can be written when necessary, whether for a native UI or to work with platform-specific APIs. KMM offers flexibility while retaining native programming benefits. However, because application business logic including data management, analytics, and authentication can be identical, it’s natural to share some parts of an application across platforms while keeping other parts separate.
