## Declaration

```swift
class func components(fromLocaleIdentifier string: String) -> [String : String]
```

## Parameters

- `string`: A locale ID, consisting of language, script, country, variant, and keyword/value pairs, for example, "en_US@calendar=japanese".

## Return Value

Return Value A dictionary that is the result of parsing string as a locale ID. The keys are the constant NSString constants corresponding to the locale ID components, and the values correspond to constants where available. For possible values, see NSLocale.Key.

## Discussion

Discussion For example, the locale identifier "en_US@calendar=japanese" yields a dictionary with three entries: languageCode = en countryCode = US calendar = NSJapaneseCalendar
