Make conforming struct to Codable (Encodable & Decodable) protocol is super easy: just declare it. But do I have to write all boiler code (CodingEnum, init(from decoder: Decoder), encode(to encoder: Encoder), etc) if I want make class conforming to Codable?

No, you haven't to do it. Example:
import Foundation
class Message: Codable {
let id: Int = 1
let text: String = "Hello"
}
let message = Message()
let encoder = JSONEncoder()
let json = try encoder.encode(message)
print(String(data: json, encoding: String.Encoding.utf8)!)

Found why my class can not "auto-conform" to Codable, because it has property of Dictionary [String: Any] (JSON). So how to make Dictionary
conform to Codable? – zzheads Sep 21 '17 at 09:06 -
`[String: Any]` can't conform for `Codable` because `Any` doesn't conform to `Codable` protocol. – Max Potapov Sep 21 '17 at 09:12
