Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36177 react_native_assert calls C `assert()`, where XCode does not have a built-in breakpoint navigator to hook to assertion failures (though you can add a symbolic breakpoint to "abort()" to get the effect). This changes the Apple implemented of `react_native_assert()` to use `NSCAssert` under the hood. This is safe to use in C functions, but will be trapped by the default XCode exceptions breakpoint navigator. Changelog: [iOS][Fixed] - Use NSCAssert() in react_native_assert instead of C assert() Reviewed By: cipolleschi Differential Revision: D43275024 fbshipit-source-id: 43c4e4f1ae6b99f32634d4b1880bce712c3ae8f6

// react_native_assert allows us to opt-in to specific asserts on Android and
|
|
// test before moving on. When all issues have been found, maybe we can use
|
|
// `UNDEBUG` flag to disable NDEBUG in debug builds on Android.
|
|
|
|
// Asserting is appropriate for conditions that:
|
|
// 1. May or may not be recoverable, and
|
|
// 2. imply there is a bug in React Native when violated.
|
|
// For recoverable conditions that can be violated by user mistake (e.g. JS
|
|
// code passes an unexpected prop value), consider react_native_expect instead.
