JSON을 enum associated value로 Decoding 하기

안녕하세요.

 

JSON을 Decoding 할 때 enum associated value도 잘 될까? 하는 의문이 있어서 직접 해봤습니다ㅋㅋ

 

결론은 key 값만 잘 맞추면 잘 되는 것 같아요! 갓스위프트

 

	struct User: Codable {
	let userID: String
	}
	enum Response: Codable {
	case success(user: User)
	case fail(message: String, code: Int)
	}
	let jsonString1 = """
	{
	"success" : {
	"user" : {
	"userID" : "AAAA"
	}
	}
	}
	"""
	let response1 = try JSONDecoder().decode(Response.self, from: jsonString1.data(using: .utf8)!)
	print(response1) // success(user: __lldb_expr_13.User(userID: "AAAA"))
	let jsonString2 = """
	{
	"fail" : {
	"message" : "something wrong",
	"code" : -999
	}
	}
	"""
	let response2 = try JSONDecoder().decode(Response.self, from: jsonString2.data(using: .utf8)!)
	print(response2) // fail(message: "something wrong", code: -999)
