With a certain project in Xcode 9 beta 6 when I try to Upload to the App Store I get:
I am the \"Admin\" role for this account.
I encountered the same issue with xCode 9 GM build and others reported it as well in xCode 10 and xCode 11. Deleting the derived data actually solved it for me. Hopefully it will help others as well.
rm -fr ~/Library/Developer/Xcode/DerivedData/
