Enumeration Case


Error code indicating that an unknown or unexpected error occurred.




For more information about the underlying cause of the error, see the localizedDescription property of the error object.

When this error occurs during testing, it can often be resolved by logging out of iTunes and/or the App Store and creating a new test user account in App Store Connect. This approach only works when running the app on a device, not the simulator.

When this error occurs in production, it may indicate a problem with the user’s iTunes account.
