Same problem here:
Dear Developer,
We identified one or more issues with a recent delivery for your app, "Circle K Easy Fuel" 2.7.72 (1996). Please correct the following issues, then upload again.
ITMS-90338: Non-public API usage - The app references non-public symbols in Easy Fuel: _SFAuthenticationErrorDomain. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed. For further information, visit the Technical Support Information at http://developer.apple.com/support/technical/
