I have created one..but shows error
struct Home2Response: Codable {
var status, error: Bool?
var data: [Home2ResponseDatum]?
var cartItemsCount, totalCartPrice: Int?
var isAuthenticated: Bool?
var newNotificationCount: Int?
var cashBackMsg: String?
enum CodingKeys: String, CodingKey {
case status, error, data
case cartItemsCount = "cart_items_count"
case totalCartPrice = "total_cart_price"
case isAuthenticated = "is_authenticated"
case newNotificationCount = "new_notification_count"
case cashBackMsg = "cash_back_msg"
}
}
// MARK: - Home2ResponseDatum
struct Home2ResponseDatum: Codable {
var type: Int?
var title: String?
var datumDescription: String?
var data: [Any]?
enum CodingKeys: String, CodingKey {
case type, title
case datumDescription = "description"
case data
}
}

Answer 1

The name in JSON should match the one in your struct.
Change datumDescription into description.
struct Data : Codable {
let type : Int?
let title : String?
let description : String?
let data : [Data]?
