# kSecNoGuest

Not a valid SecGuestRef object.

## Declaration

```swift
var kSecNoGuest: SecGuestRef { get }
```

## Discussion

Discussion Some functions in the API use this value to indicate that there is no guest, and some functions use it to indicate that the function applies to the host itself rather than to a guest.
