func CFErrorCreateWithUserInfoKeysAndValues(_ allocator: CFAllocator!, _ domain: CFErrorDomain!, _ code: CFIndex, _ userInfoKeys: UnsafePointer<UnsafeRawPointer?>!, _ userInfoValues: UnsafePointer<UnsafeRawPointer?>!, _ numUserInfoValues: CFIndex) -> CFError!
```

- `code`: A CFIndex that identifies the error code. The code is interpreted within the context of the error domain.
- `userInfoKeys`: An array of numUserInfoValues CFStrings used as keys in creating the userInfo dictionary. The value of this parameter can be NULL if numUserInfoValues is 0.
- `userInfoValues`: An array of numUserInfoValues CF types used as values in creating the userInfo dictionary. The value of this parameter can be NULL if numUserInfoValues is 0.
- `numUserInfoValues`: The number of keys and values in the userInfoKeys and userInfoValues arrays.
