# SecTransformMetaAttributeType.deferred

The attribute defers notifications.

## Declaration

```swift
case deferred
```

## Discussion

Discussion Determines if the AttributeSetNotification notification or the ProcessData blocks are deferred until SecTransformExecute(_:_:) is called. This metadata value has a default value of true for the input attribute but is false for all other attributes.
