# isModalInPresentation

A Boolean value indicating whether the view controller enforces a modal behavior.

## Declaration

```swift
var isModalInPresentation: Bool { get set }
```

## Discussion

Discussion The default value of this property is false. When you set it to true, UIKit ignores events outside the view controller’s bounds and prevents the interactive dismissal of the view controller while it is onscreen.
