They are two protocols that convert the data.
In Swift, the Codable protocol is used to go from a JSON data object to an actual Swift class or struct. This is called decoding because the JSON data is decoded into a format that Swift understands. It also works the other way: encoding Swift objects as JSON.
Simple: Convert whole data into the language that we chose. JSON → C++, Python, Swift .....
Swift can generate code to decode JSON into these structs because the Product's properties are all Decodable. This means that Response's properties are also all Decodable since [Product] is Decodable. Remember, arrays are Decodable (or Codable ) as long as their Element is Decodable (or Codable ).
Codable 은 typealias 라는 스위프트에 별명을 달수 있는게 있는데
Encodable 이랑 decodable을 통으로 codable로 부를수 있도록 만든거에요
Encodable 은 모델 -> 제이슨
디코더블은 제이슨 -> 모델
로 해주는 애들이라고 보시먄 됩니다!
별칭 관련해서는 요거 참고해보세요!
