were you able to figure out what was the issue ?
Hey there, I was facing the same problem. I solved it by going to pods file > see the Inspector on the right and change project format from xcode 10 to xcode 11.
Hope this helps cheers
For me entering "sudo rm -f /Library/Developer/CommandLineTools/usr/lib/swift/macosx/libswift*.dylib" in the terminal solved exactly the same issue you have. I hope it helps.
