FAQPage Schema
How do I test React Native native modules that won't run in Expo Go?

How do I configure EAS Build to distribute a custom Expo dev client?

To distribute a custom Expo dev client, configure EAS Build to manage development client creation and deployment workflows. This setup streamlines local build testing and enables app distribution for TestFlight submissions on iOS and Android devices.

Can I use an Expo dev client for TestFlight submissions on iOS?
