# isPrefetchingEnabled

A Boolean value that indicates whether to allow cell and data prefetching.

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

## Discussion

When <doc://com.apple.documentation/documentation/Swift/true>, the table view may request cells in advance of displaying them. When <doc://com.apple.documentation/documentation/Swift/false>, the table view requests cells when they need to display. Setting this property to <doc://com.apple.documentation/documentation/Swift/false> also disables data prefetching. The default value of this property is <doc://com.apple.documentation/documentation/Swift/true>.
