# animator()

Returns a proxy object for the receiver that can be used to initiate implied animation for property changes.

## Declaration

```swift
func animator() -> Self
```

## Return Value

Return Value Returns a proxy object for the receiver that can initiate implied animations in response to property changes.

## Discussion

Discussion The animator proxy object  should be treated as if it was the receiver itself, and may be passed to any code that accepts the receiver as a parameter. Sending key-value coding compliant “set” messages to the proxy will trigger animation for automatically animated properties of its target object, if the active NSAnimationContext in the current thread has a duration value greater than zero, and an animation for the property key is found by the NSAnimatablePropertyContainer search mechanism.
