# present(_:animator:)

Presents another view controller using a specified, custom animator for presentation and dismissal.

## Declaration

```swift
func present(_ viewController: NSViewController, animator: any NSViewControllerPresentationAnimator)
```

## Parameters

- `viewController`: The other view controller to present from the view controller. note: The view controller you provide in this parameter must not already be visible elsewhere, or else this method raises an exception. The view in the presented view controller must have a window, or else this method raises an exception.
- `animator`: The animation delegate to employ for presentation and dismissal of the other view controller. The animator that you specify is retained until the doc://com.apple.appkit/documentation/AppKit/NSViewController/dismiss(_:)-91my5 method is called and the dismissal animation completes. note: This parameter’s value must not be nil, or else this method raises an exception.

## Discussion

Discussion Do not call this method unless you want to use a custom animator. To use one of the standard animators to present another view controller, instead call one of the dedicated presentation methods: present(_:asPopoverRelativeTo:of:preferredEdge:behavior:) presentAsModalWindow(_:) presentAsSheet(_:) Each of these methods calls this method in turn. User interaction is blocked during presentation and dismissal.
