# localizedString(forLanguageCode:)

Returns the localized string for the specified language code.

```
func localizedString(forLanguageCode languageCode: String) -> String?
```

## Parameters

`languageCode`

The language code indicating the language whose name you want.

## Return Value

The localized name of the language.

## Discussion

For example, calling this method on an American English (`en_US`) locale, passing `"zh"` for `languageCode`, produces the string `"Chinese"`.

This method is equivalent to calling the [`displayName(forKey:value:)`](/documentation/Foundation/NSLocale/displayName(forKey:value:)) method passing the [`languageCode`](/documentation/Foundation/NSLocale/Key/languageCode) key and `languageCode` value.
