Required @SWG\Info() not found

The problem is - you're missing the @SWG\Info block. It's a block which tells swagger some most common information about your API.

I usually put this in a separate controller which is rendering swagger JSON. Here's an example:

/**
 * @SWG\Swagger(
 *     schemes={"http","https"},
 *     host="api.host.com",
 *     basePath="/",
 *     @SWG\Info(
 *         version="1.0.0",
 *         title="This is my website cool API",
 *         description="Api description...",
 *         termsOfService="",
 *         @SWG\Contact(
 *             email="[email protected]"
 *         ),
 *         @SWG\License(
 *             name="Private License",
 *             url="URL to the license"
 *         )
 *     ),
 *     @SWG\ExternalDocumentation(
 *         description="Find out more about my website",
 *         url="http..."
 *     )
 * )
 */
