# isEnabled

A Boolean value that determines whether the UI update link is monitoring UI updates.

```
var isEnabled: Bool { get set }
```

## Discussion

By default, the value of this property is <doc://com.apple.documentation/documentation/Swift/true>, which means the system invokes the actions of the UI update link for each UI update.

When the value is <doc://com.apple.documentation/documentation/Swift/false>, the UI update link has no effect. Set the value to <doc://com.apple.documentation/documentation/Swift/false> if you want to temporarily turn off the UI update link.
