PhoneNumberKit.defaultRegionCode() wrongly returns country code based on language on macOS about phonenumberkit

[xhruso00]

Private framework "ContactsFoundation.framework" contains [CNPhoneNumberHelper defaultCountryCode] which resolves into [[NSLocale currentLocale] objectForKey:@"NSLocaleCountryCode"]. These calls are private methods but they indicate that this library current implementation is incorrect.

PNK doesn't use any private framework and you can check it's available for macOS: https://developer.apple.com/documentation/contacts/cncontactsuserdefaults/1403200-countrycode

The issue you're facing is probably because of permissions. For macOS, the app must have access to Contacts (System Preferences > Privacy & Security > Contacts).

For the first time, the system will ask for permission, but if you don't allow access or change it later, the system will automatically return the language set on system level.

@bguidolim Please read my post again. I did the reverse engineering where I mentioned private frameworks. Found that the result of the call is WRONG as it returns postal address. It has nothing to do with private frameworks neither permissions checks.
