In this stream, we dived into Live Activities: iPhone’s interactive Lock Screen and Dynamic Island widgets that deliver real-time updates straight from your app.

We walked through the fundamentals of ActivityKit, built a working example in a fresh Expo project, and explored how native Swift modules connect seamlessly with React Native.

We also touched on:

  • The newly announced Solito 5 and what it means for cross-platform devs
  • A look at Expo UI and the future of unified native components
  • A quick highlight from Jan’s journey with Meta Quest

If you’re curious how to blend React Native flexibility with native iOS power, this stream’s for you.
