After building and Archiving my App I was unable to Validate or Upload into the App Store due to missing iOS Distribution identity. 

After verifying that all credentials exist in the member center, restarting XCode and iOS the following post from stackoverflow fixed my issue

1. Download https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
2. Double-click to install to Keychain.
3. Then in Keychain, Select View -> "Show Expired Certificates" in Keychain app.
4. It will list all the expired certifcates.
5. Delete "Apple Worldwide Developer Relations Certificate Authority certificates" from "login" tab
6. And also delete it from "System" tab.
