Note: i use method create value like this
for i in 0 ..< self.dataProduct.count {
let id_sell = "\(self.dataProduct[i].seller_id ?? 0)"
let origin = self.dataProduct[i].origin ?? 0
let product = self.dataProduct[i].product ?? []
var dataItem = [DataCheckoutMitras.ProductItemCheckout]()
var itemMitra : DataCheckoutMitras?
var dataCourierSelected : CourierObject?
for x in 0 ..< product.count {
var item : DataCheckoutMitras.ProductItemCheckout?
item = DataCheckoutMitras.ProductItemCheckout(product_id: product[x].product_id ?? 0,
name: product[x].name ?? "",
price: product[x].price ?? 0,
subTotal: product[x].subTotal ?? 0,

dataCourierSelected = self.dataKurir[x]
}
}
itemMitra = DataCheckoutMitras(origin: origin, select_price_courier: dataCourierSelected, items: dataItem)
mitras.append(itemMitra!)
}

Answer 1

The issue you are facing is because you are printing definition of your struct. What you want is the JSON to do so you will need to:
Implement Codable protocol in both of your struct
This also applied to your CourierObject
struct DataCheckoutMitras: Codable {
let origin: Int?
let items: [ProductItemCheckout]?
struct ProductItemCheckout: Codable {
let product_id : Int?
let name : String?
}
}
encode the struct to JSON data using JSONEncoder
let encodedJSONData = try! JSONEncoder().encode(mitras)
convert JSON to string
let jsonString = String(data: encodedJSONData, encoding: .utf8)
print(jsonString)
