# region

The region used by the locale.

## Declaration

```swift
var region: Locale.Region? { get }
```

## Discussion

Discussion This property corresponds to the rg key of the Unicode BCP 47 extension. For locale instances created with the rg specifier (such as en-GB@rg=US), or with a custom Locale.Components, this property represents the custom region. Otherwise, it represents the language’s region.
