# hidesBackButton

A Boolean value that determines whether the navigation item hides the Back button.

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

## Discussion

When set to <doc://com.apple.documentation/documentation/Swift/true>, the Back button is hidden when this navigation item is the top item. This is true regardless of the value in the [`leftItemsSupplementBackButton`](/documentation/UIKit/UINavigationItem/leftItemsSupplementBackButton) property. When set to <doc://com.apple.documentation/documentation/Swift/false>, the Back button is shown if it’s still present. (It can be replaced by values in either the [`leftBarButtonItem`](/documentation/UIKit/UINavigationItem/leftBarButtonItem) or [`leftBarButtonItems`](/documentation/UIKit/UINavigationItem/leftBarButtonItems) properties.) The default value is <doc://com.apple.documentation/documentation/Swift/false>.
