Swift - Create data model from JSON response

Question

I\'m learning Swift lang and one of the things that would be great to hear others input about is \"How you handle models from JSON responses\"? For example -

I would suggest using SwiftyJSONModel there your model would look something like:

import SwiftyJSONModel

class User: NSObject, JSONObjectInitializable {
    enum PropertyKey : String {
        case user_token, email
    }

    var user_token:String?
    var email:String?

    required init(object: JSONObject) throws {
        user_token = object.value(for: .user_token)
        email = object.value(for: .email)
    }
}

This library has 3 nice things:

1. You don't have to explicitly cast to String as library will infer the type
2. You can have non-optional properties and library will tell you which exact field was wrong
3. All the keys to the model are incapsulated in enum which gives you auto-complition when you type the keys and guarantees that you cannot access keys, that are not in enum
