Codeable in Swift 4
summary
Swift 4’s Codable auto generates encode and decode methods so JSON round trips become two lines using JSONEncoder/JSONDecoder. Examples show strings, dictionaries, structs and enums working out of the box, enums-as-nonstring-keys become arrays, and a UIColor is encoded as four RGBA numbers or as an object when using a keyed vs unkeyed container. Limitation: UIKit classes cannot gain Decodable in an extension so use a small wrapper type. CodingKeys maps JSON names to different property names.
