API Decoding Struct Swift - json

Question

Hello I'm trying to decode this API, https://gorest.co.in/public-api/posts. What I'm doing wrong with structs? Thank you.
struct Root: Decodable {
let first: [Code]
let second: [Meta]
let third: [Post] }
struct Code: Decodable {
let code: Int
}
struct Meta: Decodable {
let meta: [Pagination]
}
struct Pagination: Decodable {
let total: Int
let pages: Int
let page: Int
let limit: Int
}
struct Post: Decodable {
let id: Int
let user_id: Int
let title: String
let body: String
}

Quicktype.io is your friend. Post the JSON to it and get the struct back automatically.
// This file was generated from JSON Schema using quicktype, do not modify it directly.
// To parse the JSON, add this file to your project and do:
//
// let root = try? newJSONDecoder().decode(Root.self, from: jsonData)
import Foundation
// MARK: - Root
struct Root: Codable {
let code: Int
let meta: Meta
let data: [Datum]
}
// MARK: - Datum
struct Datum: Codable {
let id, userID: Int
let title, body: String
enum CodingKeys: String, CodingKey {
case id
case userID = "user_id"
case title, body
}
}
// MARK: - Meta
struct Meta: Codable {
let pagination: Pagination
}
// MARK: - Pagination
struct Pagination: Codable {
let total, pages, page, limit: Int
}
