# delegate

The navigation bar’s delegate object.

## Declaration

```swift
weak var delegate: (any UINavigationBarDelegate)? { get set }
```

## Discussion

Discussion The delegate must conform to the UINavigationBarDelegate protocol. The default value is nil. If the navigation bar was created by a navigation controller and is being managed by that object, you must not change the value of this property. A navigation controller acts as the delegate for the navigation bar it creates.
