# updateTrackingAreas()

Invoked automatically when the view’s geometry changes such that its tracking areas need to be recalculated.

## Declaration

```swift
func updateTrackingAreas()
```

## Discussion

Discussion You should override this method to remove out of date tracking areas and add recomputed tracking areas; your implementation should call super.
