# UICollectionLayoutSectionOrthogonalScrollingProperties.DecelerationRate

Constants that specify the rate of deceleration in the orthogonal scrolling section after the scrolling pan gesture ends.

```
struct DecelerationRate
```

## Topics

### Selecting deceleration rates

[`static let automatic: UICollectionLayoutSectionOrthogonalScrollingProperties.DecelerationRate`](/documentation/UIKit/UICollectionLayoutSectionOrthogonalScrollingProperties/DecelerationRate-swift.struct/automatic)

A deceleration rate that matches the parent scroll view’s deceleration rate for the orthogonal scrolling section.

[`static let fast: UICollectionLayoutSectionOrthogonalScrollingProperties.DecelerationRate`](/documentation/UIKit/UICollectionLayoutSectionOrthogonalScrollingProperties/DecelerationRate-swift.struct/fast)

A rapid deceleration rate for the orthogonal scrolling section.

[`static let normal: UICollectionLayoutSectionOrthogonalScrollingProperties.DecelerationRate`](/documentation/UIKit/UICollectionLayoutSectionOrthogonalScrollingProperties/DecelerationRate-swift.struct/normal)

The default deceleration rate for the orthogonal scrolling section.

### Creating a deceleration rate

[`init(rawValue: CGFloat)`](/documentation/UIKit/UICollectionLayoutSectionOrthogonalScrollingProperties/DecelerationRate-swift.struct/init(rawValue:))

Creates a deceleration rate.
