# name

A name associated with a filter.

## Declaration

```swift
var name: String { get set }
```

## Discussion

Discussion You use a filter’s name to construct key paths to its attributes when the filter is attached to a Core Animation layer. For example, if a CALayer object has an attached CIFilter instance whose name is myExposureFilter, you can refer to attributes of the filter using a key path such as filters.myExposureFilter.inputEV. Layer animations may also access filter attributes via these key paths. Core Animation can animate this property on a layer. The default value for this property is nil.
