# CFLocaleCreateComponentsFromLocaleIdentifier(_:_:)

Returns a dictionary containing the result from parsing a locale ID consisting of language, script, country or region, variant, and keyword/value pairs.

```
func CFLocaleCreateComponentsFromLocaleIdentifier(_ allocator: CFAllocator!, _ localeID: CFLocaleIdentifier!) -> CFDictionary!
```

## Parameters

`allocator`

The allocator to use to allocate memory for the new object. Pass `NULL` or `kCFAllocatorDefault` to use the current default allocator.

`localeID`

The locale ID to use when creating the locale dictionary.

## Return Value

A dictionary containing the result from parsing a locale ID consisting of language, script, country or region, variant, and keyword/value pairs. Returns `NULL` if there was a problem creating the object. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029).

## Discussion

The dictionary keys are the constant CFString objects that correspond to the locale ID components; the values correspond to constants where available. For example: the string “en_US@calendar=japanese” yields a dictionary with three entries: `kCFLocaleLanguageCode``=en`, `kCFLocaleCountryCode``=US`, and `kCFLocaleCalendarIdentifier``=``kCFJapaneseCalendar`. See also [`CFLocaleCreateLocaleIdentifierFromComponents(_:_:)`](/documentation/CoreFoundation/CFLocaleCreateLocaleIdentifierFromComponents(_:_:)).
