# subtitle

The localized text that provides the notification’s secondary description.

## Declaration

```swift
var subtitle: String { get set }
```

## Discussion

Discussion Use this property to specify additional context about the purpose of the notification. Subtitles offer additional context in cases where the title alone isn’t clear. Subtitles aren’t displayed in all cases. If your app isn’t authorized to display alert-based notifications, the system ignores this property.
