React-native-firebase: Build fails with error: library not found for -lFirebaseCore 🔥

[echaritonidis]

Issue

Hello,
I have a problem building my app on ios platform.
Please note on the android it works fine.

So I followed successfully the ios setup
but when I build with xcode 10, I'm getting ld: library not found for -lFirebaseCore
Same issue as this
for debug and release.
I've tried changing to Legacy Build System as described, changed also the Build location
to custom paths.

The full message:

Seems that I messed something inside the /ios, that's why it wasn't building..
I'm using the ignite boilerplate for my project and I regenerated the project and then replaced the ios/ folder
with my actual, re-linked everything and now it's working fine.

[darshanakkhichi]

hey @mkchx I'm facing the same issue with my ionic app. Can you tell what fixes worked for you in that /ios folder?
Thanks

[yongloon]

Anyone know the steps to fix this? i faced this issue also.

[echaritonidis]

Did you install the library for iOS correctly?
Guid -> https://github.com/invertase/react-native-firebase-docs/blob/master/docs/installation/ios.md
What's in your pod file?

[ParshantAroras]

Pod update works Thanks

[sattaman]

I'm facing this too , it is only failing in release , related to https://github.com/invertase/react-native-firebase/issues/1563 . pod update , reinstalling and cleaning haven't worked.

@sattaman this is a closed issue, please open a new issue if you have problems, following the provided template, so others can help. Note that the current instructions do not work well for me when integrating react-native-firebase v5.x.x, but I have a partial solution while I work with the maintainers on a full fix, visible here #2163
