## Declaration

```swift
class func criticalSoundNamed(_ name: UNNotificationSoundName, withAudioVolume volume: Float) -> Self
```

## Parameters

- `name`: The name of the sound file to play. This file must be located in the current executable’s main bundle or in the Library/Sounds directory of the current app container directory. If files exist at both locations, the system uses the file from the Library/Sounds directory. This parameter must not be nil.
- `volume`: The volume must be a value between 0.0 and 1.0.

## Return Value

Return Value A sound object representing a custom critical alert sound at the specified volume.

## Discussion
