# CFStringCapitalize(_:_:)

Changes the first character in each word of a string to uppercase (if it is a lowercase alphabetical character).

## Declaration

```swift
func CFStringCapitalize(_ theString: CFMutableString!, _ locale: CFLocale!)
```

## Parameters

- `theString`: The string to be capitalized. If this value is not a CFMutableString object, an assertion is raised.
- `locale`: A locale that specifies a particular language or region. Prior to OS X v10.3, this parameter was an untyped pointer and not used.
