I solved it by adding hermes.xcframework file to xcode > build phases > Link binary with Libraries just press to + sign and search for hermes Add it and rebuild your app.

This works for builds with xcode, but not for cmd-builds like react-native uses: npx react-native run-ios any fix for this?

Yes in xCode you will need to Embed & Sign hermes framework and then build again using command. It will work.

@allemanfredi could you help me understand why that is needed/what it does? 🤔
