@bharatbiswal did you end up getting it working? I'm getting the same issue on Xcode 10

See invertase/react-native-firebase#1610

Did Anyone get this working? reverting back to 4.3.8 doesnt work.

any update on this? it is damn annoying to not get past this.

[CyrusZei]

it has to do with the gRPC-C++ and that firestore is using this.
if you comment out firestore from your podfile and pod install it will work, bur then if you need firestore you are pretty much doomed =/

would be nice if somebody could look into this. I am so lost

[CyrusZei]

try this fix, it worked for me
