# alwaysUsesMultipleValuesMarker

A Boolean value that indicates whether the receiver always returns the multiple values marker when multiple objects are selected

## Declaration

```swift

```

## Discussion

Discussion The default is false. Setting to true can increase performance if your application doesn’t allow editing multiple values. This property is observable using key-value observing.
