What if you could ship native iOS Live Activities and Dynamic Island experiences without writing a single line of Swift? This talk tells the story of Voltra, a library born from a viral tweet and a collaboration between Saul Sharma and Callstack to bridge the gap between React and native iOS extensions.

We'll go behind the scenes of building a custom React renderer from scratch to translate JSX into SwiftUI primitives, bypassing the traditional "Swift wall." You will learn how we tackled the extreme technical constraints of the platform: from the tiny 4KB data limit to server-side driven UI that doesn't require a pre-shipped implementation.

Join us for a deep dive into Voltra's architecture and learn how you can start shipping React to a brand-new platform today.
