# layer

The view’s Core Animation layer to use for rendering.

## Declaration

```swift
var layer: CALayer { get }
```

## Discussion

Discussion This property is never nil. The value of the layerClass property determines the actual class of the layer object. The view is the layer’s delegate. warning: Because the view is the layer’s delegate, never make the view the delegate of another CALayer object. Additionally, never change the delegate of this layer object.
