var numberingSystem: Locale.NumberingSystem { get }Discussion
This property corresponds to the nu key of the Unicode BCP 47 extension.
For locale instances created with the nu specifier (such as en-US@nu=jpanfin), or with a custom Locale.Components, this property represents the custom numbering system. Otherwise, it represents the locale’s default numbering system.
