How can I convert Json data that have `[String:Any]` using `Codable` protocol

Question

I'm making a framework. I want to convert server response JSON using Codable protocol. But it have [String:Any] value. How can I clear the Error? Type 'Person' does not conform to protocol 'Encodable'

public class Person: Codable {
    public var name: String?
    public var age: Int?
    public var userOriginalData: [String:Any]? // [String:Any]? or data? or Row JSON string
}

The `Codable` protocol requires concrete types which conform to `Codable` themselves. `Any` is not supported. — vadian, Jan 25 '18 at 05:59

Thank you. I can't use `Any` with `Codable` protocol. I understood. — Maiko Ohkawa, Jan 26 '18 at 05:16

Hi Please check my Answer I am not getting any error.

  import UIKit
    struct Website : Decodable {
        let name : String
        let description : String
        let courses : [Course]
    }
    struct Course : Decodable {
        let id : Int?
        let name : String?
        let link : String?
        let imageUrl : String?
    }

    class ViewController: UIViewController {
        override func viewDidLoad() {
            super.viewDidLoad()
            getStartedBtn.setTitle(GetStarted, for: .normal)
            // Do any additional setup after loading the view, typically from a nib.
            self.callAPI()
        }
        override func didReceiveMemoryWarning() {
            super.didReceiveMemoryWarning()
            // Dispose of any resources that can be recreated.
        }
        func callAPI(){
            let urlString = "https://api.letsbuildthatapp.com/jsondecodable/website_description"
            guard let url = URL.init(string: urlString) else {
                return
            }
            URLSession.shared.dataTask(with: url) { (data, response, error) in
                guard let data = data else {
                    return
                }
                do {
                let web = try JSONDecoder().decode(Website.self, from: data)
                print(web.courses[0])
                }
                catch let error {
                print("error",error)
            }
        }.resume()
        }
    }

You can use codable instead of Decodable because it is typealias — Mahesh kumar, Jan 25 '18 at 10:33
If public var userOriginalData: [String:Any]? .. userOriginalData is dictionary so you simply create a userOriginalData as class or structure and it confirms Decodable protocol and JSONCoder() automatically parse your data. — Mahesh kumar, Jan 25 '18 at 10:37
Thank you Mahesh kumar. However I can't know a structure of `userOriginalData` and it will change by user. Because I'm making a framework and `userOriginalData`'s structure is defined by user. Thanks anyway. — Maiko Ohkawa, Jan 26 '18 at 05:23
