# criticalAlert

The ability to play sounds for critical alerts.

## Declaration

```swift
static var criticalAlert: UNAuthorizationOptions { get }
```

## Discussion

Discussion Critical alerts ignore the mute switch and Do Not Disturb; the system plays a critical alert’s sound regardless of the device’s mute or Do Not Disturb settings. You can specify a custom sound and volume. Critical alerts require a special entitlement issued by Apple.
