Kotlin User Group Serbia

Kotlin is turning 15, and we're throwing a party to celebrate! 🎉
Join us on 29th September for an evening of food, drinks and good company with the Kotlin community in Belgrade - plus a technical talk on one of the most practical challenges facing multiplatform teams today: making Kotlin and Swift actually work together in real production apps.

Aleksa Simić - Kotlin–Swift Interoperability: Lessons from Real Projects

About four years ago, Aleksa's team started adopting Kotlin Multiplatform on real client projects. This talk is the story of what happened next - told from the perspective of the people who had to live with the results: the iOS developers.
We'll look at how Kotlin–Swift interop actually works under the hood, and at the challenges it brings when shared Kotlin code meets a native iOS codebase. Aleksa will walk us through the concrete problems his iOS team ran into when consuming the generated APIs, the tools and workarounds they adopted to streamline the iOS development experience, and how that setup evolved over the past four years - from the early rough edges to where they are today.
If you're using KMP in an existing iOS and Android app, or planning to introduce it gradually, this is a chance to learn from four years of real-world experience rather than a hello-world demo.

About our speaker
Aleksa Simić is CTO and co-founder of Aetherius, a company that builds mobile applications for clients around the world. He started his career as an iOS developer and spent over 8 years working primarily on native iOS applications, before shifting his focus to Kotlin Multiplatform. Today he leads the mobile team and works on projects that combine native and KMP approaches, with a particular focus on gradually integrating shared code into existing iOS and Android applications.
Through his work on enterprise projects, Aleksa has focused extensively on the challenges and specifics of Kotlin–Swift interoperability, and on how it can be best leveraged.
