While the Hermes engine is cross-platform, the memory management patterns on iOS (specifically regarding how the system handles EXC_BAD_ACCESS for deallocated objects) tend to surface these threading bugs more aggressively than on Android. When a gesture is performed on iOS, the interaction thread attempts to communicate with the JS thread via JSI. If the decorator fails to protect the runtime, the app attempts to access a memory location that no longer exists, leading to the C++ exception and crash.

react-native-reanimated heavily relies on custom C++ bindings over the JSI layer.

Another real-world occurrence was tracked via Sentry in the Integreat App. The error presented as an unhandled TypeError where the system could not read the property localeCompare of an undefined variable inside a CitySelector component. The stack trace showed that the error occurred during a city sorting and filtering operation ( citySort and filterSortCities ), suggesting that the JSI exception corrupted the state of the JavaScript object responsible for storing city data.

Utilize tools like Sentry or New Relic to monitor JavaScript errors in real-time. Detailed logs can significantly speed up the debugging process. While the Hermes engine is cross-platform
