func CFHTTPMessageCreateResponse(_ alloc: CFAllocator?, _ statusCode: CFIndex, _ statusDescription: CFString?, _ httpVersion: CFString) -> Unmanaged<CFHTTPMessage>
```

## Parameters

- `statusCode`: The status code for this message response. The status code can be any of the status codes defined in section 6.1.1 of RFC 2616.
- `statusDescription`: The description that corresponds to the status code. Pass NULL to use the standard description for the given status code, as found in RFC 2616.
- `httpVersion`: The HTTP version for this message response. Pass kCFHTTPVersion1_0 or kCFHTTPVersion1_1.

## Return Value

## Discussion

Discussion This function returns a CFHTTPMessage object that you can use to build an HTTP response. Continue building the response by callingCFHTTPMessageSetBody(_:_:) to set the message’s body. Call CFHTTPMessageSetHeaderFieldValue(_:_:_:) to set the message’s headers. Then call CFHTTPMessageCopySerializedMessage(_:) to make the message ready for transmission by serializing it.
