Swift 4+SwiftyJson convert/generate objects from JSON automatically

Question

I'm using SwiftyJSON to get a JSON from my web service. What's the easiest way to convert this into a swift object represenation?

I mean maybe a website like http://www.jsonschema2pojo.org/ which does the same for Java.

I so far found generators which work from String or Dictionary but not SwiftyJSON?

Thanks

The best option is to get rid of SwiftyJSON and use the built in JSONDecoder and Decodable. – Stepdame

You can see JSON Master, Here you can generate you code directly from JSON for SwiftyJSON, Codable framework or classical Dictionary. It can also generate struct or class.

Also it has support for Java, Kotlin and C#

Way better than the other options found in a quick google search. None of the options actually provided full encode() and decode() support except for this, and I tried at least 5. – Tremayne

Let's say for example you have a Student Model and you want to map the JSON Object to Student Object. You can try like this:

struct Student {

  let id: Int!
  let name: String!

  init(param: JSON) {
    id = param["id"].intValue
    name = param["name"].stringValue
  }

  /* JSON Response
  {
    "id": 168,
    "name": "KoingDev"
  }
  */

}

Hope it is useful! :)

Well yeah, its good if you have simple classes with few parameters. I have 50 with dozens of parameters each. hence generally I'm using generative tools to do stuff like this. – Consultation
