Roadmap updated

Kotlin roadmap updated

The Kotlin roadmap has been updated with our plans for the upcoming releases. The key priorities are making Kotlin Multiplatform and the K2 compiler Stable. The plans also include making Kotlin/Wasm suitable for standalone Wasm VMs, improving Android debugging, and extending the kotlinx-io library towards a more unified and Kotlin-first API.

Compose Multiplatform for iOS is in Alpha

Compose Multiplatform for iOS is in Alpha

Compose Multiplatform – a declarative framework designed for building cross-platform user interfaces with Kotlin – has recently gained the capability to support iOS. This means developers can now use Compose Multiplatform to create a UI entirely in Kotlin and use it on Android, iOS, and other platforms.

Compose Multiplatform for iOS is now in its Alpha stage, which makes it perfect to use in your experiments. We invite you to give it a try and help us shape the future of the technology!
