Creates a shipping address error with the supplied key and user-facing error message.
Mac Catalyst 13.0+
PassKit (Apple Pay and Wallet)
A key value from CNPostalAddress that indicates which part of the address has an error.
Optional. Provide a localized, user-facing error message string to help the user resolve the error.
You can use this convenience method to create a payment error object instead of creating an NSError object yourself. This convenience method indicates an error in the shipping address received from an Apple Pay sheet.
The error you provide and its optional message appear on the Apple Pay sheet. The available space to display messages is limited, so you should keep your messages concise.
