# sheetPresentationController

The sheet presentation controller for the view controller.

## Declaration

```swift
var sheetPresentationController: UISheetPresentationController? { get }
```

## Discussion

Discussion If modalPresentationStyle is UIModalPresentationStyle.pageSheet or UIModalPresentationStyle.formSheet, this property contains a sheet presentation controller instance. Access this instance to customize or adjust the sheet before or after it presents. If modalPresentationStyle has a value other than UIModalPresentationStyle.pageSheet or UIModalPresentationStyle.formSheet, the value of this property is nil.
