# isModalInPresentation

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

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

## Discussion

The default value of this property is <doc://com.apple.documentation/documentation/Swift/false>. When you set it to <doc://com.apple.documentation/documentation/Swift/true>, UIKit ignores events outside the view controller’s bounds and prevents the interactive dismissal of the view controller while it is onscreen.
