We’d like to say a big thank you to everyone who attended KotlinConf 2019 and to all our partners at the event. Without you, none of this would have been possible. We are incredibly grateful to all the wonderful conference speakers who shared their experiences with attendees and made the conference a really exciting and useful event.


In the Keynote, Andrey Breslav gave an overview of the strategic vision for the future of Kotlin’s evolution. Kotlin targets all platforms and is a versatile tool for bringing all sorts of ideas and products to life. Now we’re looking into how Kotlin could become the default language for all types of software development. The priority for the upcoming Kotlin 1.4 release is to ensure that the language offers an amazing experience to each and every developer, whatever their professional background or platform might be. To achieve this, the team is going to focus on quality and performance, improving the compiler, and polishing and extending the multiplatform capabilities of the language.

Andrey mentioned a number of other talks during the keynote. Most of them cover different aspects of using Kotlin on various platforms. Below is a list of the talks he mentioned for easy navigation:
