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
