# selectedIndex

The index of the selected item in the scrubber.

## Declaration

```swift
var selectedIndex: Int { get set }
```

## Discussion

Discussion If no item is selected, the value of this property is -1. If you set this property through the scrubber’s animator proxy, the selection change animates. To use a scrubber’s animator proxy when changing the selected item, employ the NSAnimatablePropertyContainer protocol, using code like this: scrubber.animator.selectedIndex = 123
