# values

An array of objects that specify the keyframe values to use for the animation.

```
var values: [Any]? { get set }
```

## Discussion

The keyframe values represent the values through which the animation must proceed. The time at which a given keyframe value is applied to the layer depends on the animation timing, which is controlled by the [`calculationMode`](/documentation/QuartzCore/CAKeyframeAnimation/calculationMode), [`keyTimes`](/documentation/QuartzCore/CAKeyframeAnimation/keyTimes), and [`timingFunctions`](/documentation/QuartzCore/CAKeyframeAnimation/timingFunctions) properties. Values between keyframes are created using interpolation, unless the calculation mode is set to [`discrete`](/documentation/QuartzCore/CAAnimationCalculationMode/discrete).

Depending on the type of the property, you may need to wrap the values in this array with an <doc://com.apple.documentation/documentation/Foundation/NSNumber> of <doc://com.apple.documentation/documentation/Foundation/NSValue> object. For some Core Graphics data types, you may also need to cast them to `id` before adding them to the array.

The values in this property are used only if the value in the [`path`](/documentation/QuartzCore/CAKeyframeAnimation/path) property is `nil`.
