# volatileDomainNames

An array of identifiers for the volatile domains associated with the current object.

```
var volatileDomainNames: [String] { get }
```

## Discussion

Each string in the array corresponds to one of the volatile domains this `UserDefaults`
object searches. To get the contents of one of these domains, call the
[`volatileDomain(forName:)`](/documentation/Foundation/UserDefaults/volatileDomain(forName:)) method.
