I have a project in React Native and suddenly this error appeared. I was doing some shit with homebrew beforehand and this solved the issue for me:

brew update
brew upgrade
brew cleanup

Answer 4

For me, I was removing Crashlytics, Fabric and FirebaseCrashlytics. So there was a script (Run Script) for Fabric. So since app was running that first and I had removed the framework already, I was getting this error. So I removed the Run Script tab for Fabrics and then it worked perfectly fine.

Answer 5

For Xcode 11, React Native development environment. I usually have this problem when a dependency is not updated.

You can try following these steps, this usually works for me:

1- Delete your Podfile.lock (I like to use the command '-rm -rf Podfile.lock' on the terminal for this)

2- Delete your Pods folder (I like to use the command '-rm -rf Pods' in the terminal for this)

3- Delete your .xcworkspace

4- Pod install

5- Clear your project into XCode> Product> Clean Build Folder
