The ISN_NSLocale will provide an  Information about linguistic, cultural, and technological conventions for use in formatting data for presentation.

The CurrentLocale property is representing the user's region settings at the time the property is read. The locale is formed from the settings for the current user’s chosen system locale overlaid with any custom settings the user has specified. Use this property when you need to rely on a consistent locale. A locale instance obtained this way does not change even when the user changes region settings.

See the code snippet below:

using SA.iOS.Foundation;
var currentLocale = ISN_NSLocale.CurrentLocale;
Debug.Log("currentLocale.Identifier: " + currentLocale.Identifier);
Debug.Log("currentLocale.CountryCode: " + currentLocale.CountryCode);
Debug.Log("currentLocale.CurrencyCode: " + currentLocale.CurrencyCode);
Debug.Log("currentLocale.LanguageCode: " + currentLocale.LanguageCode);
Debug.Log("currentLocale.CurrencySymbol: " + currentLocale.CurrencySymbol);

If you want a locale instance that always reflects the current configuration, use the one provided by the AutoupdatingCurrentLocale property instead.

using SA.iOS.Foundation;
var locale = ISN_NSLocale.AutoUpdatingCurrentLocale;
Debug.Log("Identifier: " + locale.Identifier);
Debug.Log("CountryCode: " + locale.CountryCode);
Debug.Log("CurrencyCode: " + locale.CurrencyCode);
Debug.Log("LanguageCode: " + locale.LanguageCode);
Debug.Log("CurrencySymbol: " + locale.CurrencySymbol);
