# contentsRect

A rectangle, in unit coordinate space, that describes the content area of the interaction.

## Declaration

```swift
@MainActor final var contentsRect: CGRect { get }
```

## Discussion

Discussion If the interaction’s view isn’t an instance of UIImageView, your app sets the value for this property by implementing the ImageAnalysisInteractionDelegate callback contentsRect(for:). The default return value is the unit rectangle, [0.0, 0.0, 1.0, 1.0], which represents the whole view contents.
