# backItem

The navigation item that is immediately below the topmost item on a navigation bar’s stack.

## Declaration

```swift
var backItem: UINavigationItem? { get }
```

## Discussion

Discussion If the leftBarButtonItem property of the topmost navigation item is nil, the navigation bar displays a back button whose title is derived from the item in this property. If there is only one item on the navigation bar’s stack, the value of this property is nil.
