I usually have this problem when a dependency is not updated.

Delete your Podfile.lock (I like to use the command ‘-rm -rf Podfile.lock’ on the terminal for this)
Delete your Pods folder (I like to use the command ‘-rm -rf Pods’ in the terminal for this)
Pod install

Clear your project in XCode > Product > Clean Build Folder
