# kCFErrorDescriptionKey

Key to identify the description in the userInfo dictionary.

## Declaration

```swift
let kCFErrorDescriptionKey: CFString!
```

## Discussion

Discussion When you create a CFError object, you can provide a value for this key if you do not have localizable error strings. The description should be a complete sentence if possible, and should not contain the domain name or error code.
