Reply to App Crashes on TestFlight but Works in Simulator (Expo React Native App)
Evan Bacon from the Expo team here 👋 This can often happen when a third-party library is missing an API key and throws an exception in production. Try creating a local production iOS build in release mode: npx expo run:ios --configuration Release this will be a nearly identical build to what goes into TestFlight. You can also open the project in Xcode, and customize the scheme to build with the Release configuration. While we do stream the simctl errors to the CLI, building from Xcode directly in cases like this can yield more debug info.
