# sourceRect

The rectangle, in the source view’s coordinate system, that responds to a 3D Touch by a user and remains visually sharp while surrounding content blurs.

## Declaration

```swift
var sourceRect: CGRect { get set }
```

## Discussion

Discussion Use this property if you want to specify a preview indication area that is different than the bounds of the view in the sourceView property. Set this property’s value in your object’s previewingContext(_:viewControllerForLocation:) method. The default value of this property corresponds to the bounds of the view in the sourceView property. For example, if your source view is a table view, you can set the sourceRect property to the frame of the row under the user’s touch. The row then remains visually sharp when a user presses it, while surrounding content blurs, thereby indicating to the user that it is the row being touched that has a preview available. You can change the value of this property at runtime.
