# CFUUIDBytes

A 128-bit struct that represents a UUID as raw bytes.

```
struct CFUUIDBytes
```

## Overview

This structure can be obtained from a CFUUID object using the [`CFUUIDGetUUIDBytes(_:)`](/documentation/CoreFoundation/CFUUIDGetUUIDBytes(_:)) function. This structure can be passed to functions that expect a raw UUID.
