Hi, I'm currently facing an issue where my React Native app crashes only on a real iPhone. On the simulator and in Xcode preview, the app runs fine.
Previously, I had an issue with FlatList regarding props.getItem, which I solved by installing some missing Babel dependencies. After that, everything worked correctly in the simulator.
But when I try to open the app on a real device, it shows the splash screen and crashes immediately. I've already done a full clean and reset, including:
npx react-native start --reset-cache Deleted node_modules and Pods, reinstalled everything Cleaned build folder via Xcode Deleted DerivedData Restarted Metro bundler and simulator/device The issue only happens on the physical device.
Here’s a portion of the crash log
