OpenAI vs. DeepSeek: which AI understands Kotlin better?

Kotlin Multiplatform updates

Hot Reload for Compose Multiplatform

Our team is working on Hot Reload for Compose Multiplatform! It works like a charm – you tweak your UI and you instantly see the changes. No more waiting or “Did I break it?” moments (okay, maybe just fewer of them). You instantly see and “feel” the changes you make as you tweak your app! Want to see it in action? Check out this quick video by Sebastian Aigner. And if you’re ready to bring this superpower to your own project, just head over to its GitHub repository and follow the steps in the README. Give it a try!

Compose Multiplatform 1.8.0-beta01

Compose Multiplatform 1.8.0-beta01 is out! The highlights of this release include: variable fonts, drag-and-drop on iOS, improved accessibility on iOS, resource preloading for web targets, and integration with browser navigation controls. Try it out and share your experience, feedback, and questions with us in a dedicated #compose channel on the Kotlin Slack. What’s new in Compose Multiplatform
