# decelerationRate

A floating-point value that determines the rate of deceleration after the user lifts their finger.

```
var decelerationRate: UIScrollView.DecelerationRate { get set }
```

## Discussion

The default rate is [`normal`](/documentation/UIKit/UIScrollView/DecelerationRate-swift.struct/normal). For possible deceleration rates, see [`UIScrollView.DecelerationRate`](/documentation/UIKit/UIScrollView/DecelerationRate-swift.struct).
