# UISceneCollectionJoinBehavior.preferredWithoutActivating

A behavior that adds the new scene to the requesting scene’s collection without activating it, or attempts to join a compatible collection.

## Declaration

```swift
case preferredWithoutActivating
```

## Discussion

Discussion If requestingScene is set, this behavior adds the new scene without deactivating the requestingScene. Otherwise, this behavior behaves the same as UISceneCollectionJoinBehavior.preferred. For example, in apps built with Mac Catalyst, you can use this behavior to open a link in a new tab in the background.
