Why am I getting the error: Type 'MenuItem' does not conform to protocol 'Decodable'? It was working before. One of the things I changed was modifiers from [String]? to [Modifier]? Is that producing the error? If so, why? Stackoverflow wants me to keep saying things because it's too little description relative to the amount of code that I displayed below. Still needing to add text.
struct MenuItem: Codable {
let itemId: String
let name: String
var modifiers: [Modifier]?
var photoUrl: String?
var quantity: Int
var unitPrice: Int
var sizeAddOnPrice: Int
var toppingsAddOnPrice: Int
var totalPrice: Int
var totalModifiersPrice: Int
let description: String
var size: String
var toppings: [String]?
let category: String
init(itemId: String, name: String, modifiers: [Modifier]?, photoUrl: String?, quantity: Int, unitPrice: Int, sizeAddOnPrice: Int, toppingsAddOnPrice: Int, totalPrice: Int, totalModifiersPrice: Int, description: String, size: String, toppings: [String]?, category: String) {
self.itemId = itemId
self.name = name
self.modifiers = modifiers
self.photoUrl = photoUrl
self.quantity = quantity
self.unitPrice = unitPrice
self.sizeAddOnPrice = sizeAddOnPrice
self.toppingsAddOnPrice = toppingsAddOnPrice
self.totalPrice = totalPrice
self.totalModifiersPrice = totalModifiersPrice
self.description = description
self.size = size
self.toppings = toppings
self.category = category
}
init?(itemId: String, payload: JSON) {
guard
let name = payload[ParamKey.name].string,
let photoUrl = payload[ParamKey.photoUrl].string,
let description = payload[ParamKey.description].string,
let category = payload[ParamKey.categoryName].string,
let unitPrice = payload[ParamKey.basePrice].int,
let size = payload[ParamKey.size].string
else { return nil }
self.itemId = itemId
self.name = name
self.photoUrl = photoUrl
self.description = description
self.category = category
self.unitPrice = unitPrice
self.size = size
self.sizeAddOnPrice = 0
self.toppings = nil
self.toppingsAddOnPrice = 0
self.totalPrice = (unitPrice + sizeAddOnPrice + toppingsAddOnPrice) * quantity
self.totalModifiersPrice = (sizeAddOnPrice + toppingsAddOnPrice) * 2
self.quantity = 1
self.modifiers = payload[ParamKey.modifiers].arrayObject as? [Modifier]
}
}
You need to make the inner structs conform to Decodable
/ Codable
also and remove struct init
it'll be automatically generated
struct Modifier: Codable {
// add properties
}
struct MenuItem: Codable {
let itemId: String
let name: String
var modifiers: [Modifier]?
var photoUrl: String?
var quantity: Int
var unitPrice: Int
var sizeAddOnPrice: Int
var toppingsAddOnPrice: Int
var totalPrice: Int
var totalModifiersPrice: Int
let description: String
var size: String
var toppings: [String]?
let category: String
init?(itemId: String, payload: JSON) {
guard
let name = payload[ParamKey.name].string,
let photoUrl = payload[ParamKey.photoUrl].string,
let description = payload[ParamKey.description].string,
let category = payload[ParamKey.categoryName].string,
let unitPrice = payload[ParamKey.basePrice].int,
let size = payload[ParamKey.size].string
else { return nil }
self.itemId = itemId
self.name = name
self.photoUrl = photoUrl
self.description = description
self.category = category
self.unitPrice = unitPrice
self.size = size
self.sizeAddOnPrice = 0
self.toppings = nil
self.toppingsAddOnPrice = 0
self.totalPrice = (unitPrice + sizeAddOnPrice + toppingsAddOnPrice) * quantity
self.totalModifiersPrice = (sizeAddOnPrice + toppingsAddOnPrice) * 2
self.quantity = 1
self.modifiers = payload[ParamKey.modifiers].arrayObject as? [Modifier]
}
}
You can also use
try content.rawData() // for payload: JSON) {
to JSON
to data and then supply it to the Decodable
class
