## Discussion

Discussion If there’s a problem encoding the data you supply, this method sets the error parameter based on the type of problem: The pass contains invalid data—this method throws the PKPassKitError.Code.invalidDataError error. The signature of the pass is invalid—this method throws the PKPassKitError.Code.invalidSignature error. For other types of errors, localizedDescription contains a string suitable for presentation to the user. Check the console for more detailed information.
