# withoutUI

Specifies that no UI should accompany the unmount operation.

## Declaration

```swift
static var withoutUI: FileManager.UnmountOptions { get }
```

## Discussion

Discussion If this option is not specified when calling unmountVolume(at:options:completionHandler:), any needed UI will delay completion of the completion handler.
