Cannot invoke 'UTTypeEqual' with an argument list of type '(CFString!, CFString!)'

How do I get this to compile?

On the second line of this function:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let mediaType = info[UIImagePickerControllerMediaType] as! CFString!
    if UTTypeEqual(mediaType, kUTTypeJPEG) {
        println("jpg")
    }
}

I get the compilation error:
