My problem started when I wanted to add the module @react-native-firebase/crashlytics. I had errors when I tried to add the module, so I hat to execute the following commands
rm -rf ios/Podfile.lock
pod install --repo-update
and I had to add the following line to the pod file
use_frameworks! :linkage => :static
and changed ios 12.1 to:
platform :ios, '13.0'
With this changes I was able to add crashlytics to the projects, but the app is not running anymore, I get a build error in xCode
RCTDevLoadingViewProtocol.h' file not found
