# SecTransformCreate(_:_:)

Creates a transform computation object.

## Declaration

```swift
func SecTransformCreate(_ name: CFString, _ error: UnsafeMutablePointer<Unmanaged<CFError>?>?) -> SecTransform?
```

## Parameters

- `name`: The type of transform to create. Use one of the pre-defined transform types or a custom type that you previously registered using doc://com.apple.security/documentation/Security/SecTransformRegister(_:_:_:).
- `error`: A pointer that the function uses to provide an error object with details if an error occurs. The caller becomes responsible for the object’s memory. Pass NULL to ignore the error.

## Return Value

Return Value A pointer to a new transform or NULL on failure. In Objective-C, call the CFRelease function to free this object’s memory when you are done with it.
