# kSecTransformDebugAttributeName

A write stream that should receive debug data.

## Declaration

```swift
let kSecTransformDebugAttributeName: CFString
```

## Discussion

Discussion Set this attribute to a CFWriteStream. This signals the transform to write debugging information to the stream. If you set this attribute to kCFBooleanTrue, debug data is written to stderr instead.
