The main drive behind Kotlin Multiplatform Mobile is the desire of developers to save time when coding the same application for both iOS and Android.

Kotlin is a good fit for JetBrains, whose IDEs run on the JVM, and the project has been nimbler about introducing new language features than Java itself, with its sometimes ponderous standardisation process. It is currently the 18 th most popular language in the Redmonk language rankings, just ahead of Rust. It targets the JVM (Java Virtual Machine) and also has transpilers for JavaScript and, via the LLVM project, native code for macOS, iOS, Linux, Windows, and Android NDK (Native Development Kit). Kotlin, an open-source project introduced by JetBrains in 2011, has been a Google-recommended language for Android since 2017 and the preferred language since 2019.

“We are aiming next year to be stable,” product manager Ekaterina Petrova told DevClass. JetBrains has released the first beta of Kotlin Multiplatform Mobile, a framework for coding applications for Android and iOS with the Kotlin language.
