# isActivityFullscreen

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

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

## Discussion

When a Live Activity fills the entire screen, the system extends the background
tint color you set with the <doc://com.apple.documentation/documentation/SwiftUI/View/activityBackgroundTint(_:)>
modifier to fill the screen.

Note that this environment variable is always `false` in iOS 16.
