# SecTransformMetaAttributeType

The keys that describe the metadata attributes of transform attributes.

## Declaration

```swift
enum SecTransformMetaAttributeType
```

## Overview

Overview Use one of these values as the type parameter in a call to the SecTransformCustomSetAttribute(_:_:_:_:) or SecTransformCustomGetAttribute(_:_:_:) function. These values allow you to access not only the value of an attribute, as you would do directly with calls the SecTransformSetAttribute(_:_:_:_:) or SecTransformGetAttribute(_:_:) function, but also the metadata associated with that attribute, such as the name of an attribute, or whether it is required to have a value.
