Lona is a configurable, server-driven UI system at Airbnb that renders features on Android, iOS, and web. It enables teams to rapidly build and iterate on features across platforms, removing boilerplate code for developers and bypassing limitations of native release cycles.

Powered by a Kotlin domain-specific language (DSL), Lona isn’t your ordinary server-driven UI system. It utilizes powerful features of the language to make server-driven UI maintainable and scalable. Lona also has accompanying Kotlin tooling to manage versioning, production responses, and to validate clients.

In this talk, we’ll discuss the use-cases that led server-driven UI to become a widely-used paradigm for product teams at Airbnb. We’ll explain how the Lona platform and DSL work and the benefits of using Kotlin. Finally we’ll end with a demo, showing how easy it is to build a feature end-to-end with Lona and Kotlin.

Your Multiplatform Kaptain has Arrived
Captains on the Careem platform recently got the ability to use iOS earlier this year with the launch of the iOS Captain app. Under the hood, this iOS release is powered by Kotlin Multiplatform. Having been in production for several months now with a large number of captains using both apps daily to transport people from one place to another, this talk is about our journey and things we learned on the way.

Some of the points this talk will cover:

- How we got buy-in to work on Kotlin Multiplatform in the project (both from the management and from our iOS colleagues).

- The different approaches we tried when developing the SDK and sharing it between the iOS and Android developers - what worked, what didn't, and how we resolved these issues.

- How we handle our library releases

- How we organized and set up our code

- How we decide what code to share and what not to share

While this is a technical talk, it is intended to focus more about the development process…
