I've encountered this issue while upgrading from 0.58.4 to new react-native version 0.60.4. Nothing from what i found on the internet helped me, but I managed to get it working:
Go to build settings, search for 'Header search paths', select the entry, press DELETE button.
I had these values overriden, and looks like they fell back to defaults after deletion. Also Cocoapods was complaining about it with messages in Terminal after pod install
:
[!] The `app [Release]` target overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-app/Pods-app.release.xcconfig'. This can lead to problems with the CocoaPods installation
