# transitionOptions

The animation options to use when switching between tabs.

## Declaration

```swift
var transitionOptions: NSViewController.TransitionOptions { get set }
```

## Discussion

Discussion By default, this property is set to the crossfade and allowUserInteraction options. The tab view controller uses the transition(from:to:options:completionHandler:) method to perform transitions between tabs. For more information about how transitions happen, see the description of that method.
