Is there a function in Swift to get the ISO 3166-2 codes (provinces, states) for a country?

Question

For an app I need the users to create addresses. It is important that the addresses are valid and include an ISO 3166 ALPHA-2 country code as well as an ISO 3166-2 code for the province, state, etc.

I can use NSLocale to get all country codes and the localized names for a country code but is there a similar way to get the codes and names (they doesn't have to be localized) for the subdivisions of a country or do I have to create that massive dictionary by myself? :D

Thank you in advance
