Alamofire let you easily handle the deserialization of the responses (and of course also the serialization of the requests) with the Decodable protocol (and Encodable - or Codable to support both Encodable and Decodable at the same time). Swift 4 introduces a new Codable protocol that lets you serialize and deserialize custom data types without writing any special code and without having to worry about losing your value types. You can see that we have now with Alamofire 5 a new method responseDecodable that will help us to make a request and returns a Decodable object/structure, in our case a User model. .main by default.

The queue on which the completion handler is dispatched. queue: DispatchQueue on which the DataResponse will be published. With more experience, I’m finding better ways to avoid writing as much custom code, like making the types for individual properties Codable instead of writing custom code for the top-level Codable item in my JSON.
