Xcode Archive Validation : Potential Loss of Keychain Access

Potential Loss of Keychain Access. The previous version of software has an application-identifier value of 'XXXX.com.company' and the new version of software being submitted has an application-identifier of 'YYYYY.com.company'. This will result in a loss of keychain access.

Note: This is a warning, not an error. You have the option of proceeding with the submission regardless of this warning, however this document should be used to determine whether you can safely ignore it. This warning indicates that the App ID prefix of the pending submission differs from the App ID prefix of the live app in the app store.

Important: The only apps that can safely ignore this warning are those that do not use technologies that rely on the App ID prefix, like keychain access, Handoff, and UIPasteboard sharing.
