Linker error with Cocoapods

In my react native project I have rnfirebase setup with cocoapods. And it has its own Pods xcconfig file. How do I merge these 2 (UnityConfig & Myprojects-config) files ? I tried adding #include but its still not able to find some header files.

Thanks

I’m adding new Pods this way:

1. Create Podfile and add needed Pods e.g. Firebase
2. pod install
3. Open Pods-rnunitydemo.release.xcconfig (this file includes all needed dependencies)
4. Open UnityConfig.xcconfig
5. Manually merge Pods-rnunitydemo.release.xcconfig into UnityConfig.xcconfig

I have managed to solve this:

this is my UnityConfig.debug.xcconfig:

#include "Pods/Target Support Files/Pods-VooDoog/Pods-VooDoog.debug.xcconfig"

Actually all I needed to to is to add this 4 lines to the beginning of the file :

Just copy it from you default xcconfig.

I hope it helped
