# isActivityFullscreen

A Boolean value that indicates whether the Live Activity appears in a full-screen presentation.

## Declaration

```swift
@backDeployed(before: iOS 17.0)
var isActivityFullscreen: Bool { get }
```

## Discussion

Discussion When a Live Activity fills the entire screen, the system extends the background tint color you set with the activityBackgroundTint(_:) modifier to fill the screen. Note that this environment variable is always false in iOS 16.
