At WWDC 2017, Apple has introduced the new feature in Swift to parse JSON without any pain using Swift Codable protocol

struct YourStructure: Codable {
    let name: String?
    let avatarUrl: URL?
    private enum CodingKeys: String, CodingKey {
        case name
        case avatarUrl = "avatar_url"
    }
}

decoder:

let decoder = JSONDecoder()
parsedData = decoder.decode(YourStructure.self, from: YourJsonData)

encode:

let jsonEncoder = JSONEncoder()
let jsonData = try jsonEncoder.encode(data)
