You saved my day.
Thank you so much

Thank you so much

Wow! I came for the Yoga issues but I'm gonna grab the RCTValueAnimatedNode and fishhook fixes as well, which I've been fixing manually like a goof!

Yes! I used a snippet of your code in my Podfile :

Thanks very much for posting this. It's a nice clean way to apply the patches. Hopefully the RN team will address these issues at some point! 😝

How is it this issue is still plaguing react native... maybe it's time to switch to Flutter :/

thank you very much

https://github.com/orta/cocoapods-fix-react-native centralises a lot of these hacks

Thanks!

Wow thank you

Still life saving, thanks so much!
