# CAPropertyAnimation

An abstract subclass for creating animations that manipulate the value of layer properties.

## Declaration

```swift
class CAPropertyAnimation
```

## Overview

Overview The property to animate is specified using a key path that is relative to the layer using the animation. You do not create instances of CAPropertyAnimation: to animate the properties of a Core Animation layer, create instance of the concrete subclasses CABasicAnimation or CAKeyframeAnimation.
