# isTracking

A Boolean value that indicates whether the control is currently tracking touch events.

```
var isTracking: Bool { get }
```

## Discussion

While tracking of a touch event is in progress, the control sets the value of this property to <doc://com.apple.documentation/documentation/Swift/true>. When tracking ends or is canceled for any reason, it sets this property to <doc://com.apple.documentation/documentation/Swift/false>.
