Hello,
Welcome to our Microsoft Q&A platform!
unable to build chain to self-signed root
, this usually means the self-signed root cannot be found, there's a missing WWDR intermediate certificate, or Keychain Access is being used to customize the trust settings on either the intermediate or root certificate.
I'm afraid you should download Apple Worldwide Developer Relations Certificate Authority from this link and double click it to install, then you could clean the solution and archive again.
