TL;DR
From JSON,
{
"user": {
"Name": "Yuto Mizutani"
},
"lib": {
"lib-name": "JSONtoCodable",
"year": 2018,
"version": "1.0.2",
"released": "2018-09-22"
},
"text": "Hello, world!!"
}to Codable.
public struct Result: Codable {
public let user: User
public let lib: Lib
public let text: String
public struct User: Codable {
public let name: String
private enum CodingKeys: String, CodingKey {
case name = "Name"
}
}
public struct Lib: Codable {
public let libName: String
public let year: Int
public let version: String
public let released: String
private enum CodingKeys: String, CodingKey {
case libName = "lib-name"
case year
case version
case released
}
}
