# languageCode

The language code for the locale.

```
var languageCode: String { get }
```

## Discussion

Examples of language codes include `"en"`, `"es"`, and `"zh"`.

Use [`localizedString(forLanguageCode:)`](/documentation/Foundation/NSLocale/localizedString(forLanguageCode:)) to obtain a version of the value suitable for display to the user.

This property contains the same value returned by the [`object(forKey:)`](/documentation/Foundation/NSLocale/object(forKey:)) method when passing the [`languageCode`](/documentation/Foundation/NSLocale/Key/languageCode) key.
