Description

I'm experiencing a build issue on react-native@0.75.2 and new Arch: 'react/renderer/components/rncore/EventEmitters.h' file not found on RNCSliderShadowNode when using @react-native-community/slider": "4.5.2"

What I did but no luck:

1. pod deintegrate
2. rm -rf node_modules
3. yarn install
4. RCT_NEW_ARCH_ENABLED=1 pod install
5. build on xcode

see attached screenshot:

Reproducible Demo

[efstathiosntonas]

it seems that after changing the import to: #include "EventEmitters.h" from #include <react/renderer/components/rncore/EventEmitters.h> it built fine.

I am getting the error on <react/renderer/components/rncore/EventEmitters.h> not found.

[arstropica]

The following header search path seems to be missing from my pod build settings. When I add it manually, the error goes away.

${PODS_CONFIGURATION_BUILD_DIR}/React-FabricComponents/React_FabricComponents.framework/Headers/react/renderer/components/rncore

The current release, 4.5.3, does not include this fix and so iOS NewArch does not build.

hi @BartoszKlonowski. I've checked 4.5.3 on the RN 0.75.3 with the new architecture, and this bug still exists.

[BartoszKlonowski]

Yes, the latest release does not yet include the fix for that issue.
This (along with some other topics) will be released soon, I hope for your patience.
Thank you!

Hello. Thank you so much.
I am experiencing the same issue. When can we expect a fix? If downgrade to what version? Will this work?
