# effectiveGeometry

The current values for the window scene’s geometry in system space.

## Declaration

```swift
var effectiveGeometry: UIWindowScene.Geometry { get }
```

## Discussion

Discussion This property is key-value observing (KVO) compliant. Observing effectiveGeometry is the recommended way to receive notifications of changes to the window scene’s geometry. These changes can occur because of user interaction or as a result of the system resolving a geometry request.
