Here's the code. I get an error that says "Assigning a property to itself" when I try to assign self.inventory to inventory.
import Foundation
enum VendingSelection {
case soda
case dietSoda
case chips
case cookie
case sandwich
case wrap
case candyBar
case popTart
case water
case fruitJuice
case sportsDrink
case gum
}
protocol VendingItem {
var price: Double { get }
var quantity: Int { get set }
}
protocol VendingMachine {
var selection: [VendingSelection] { get }
var inventory: [VendingSelection: VendingItem] { get set }
var amountDeposited: Double { get set }
init(inventory: [VendingSelection: VendingItem])
func vend(_ quantity: Int, _ selection: VendingSelection) throws
func deposit(_ amount: Double)
}
struct Item: VendingItem {
let price: Double
var quantity: Int
}
class FoodVengindMachine: VendingMachine {
let selection: [VendingSelection] = [.soda, .dietSoda, .chips, .candyBar, .cookie, .fruitJuice, .gum, .popTart, .sandwich, .wrap, .water, .sportsDrink]
var inventory: [VendingSelection: VendingItem]
var amountDeposited: Double = 10.0
required init(inventory: [VendingSelection : VendingItem]) {
self.inventory = inventory
}
func vend(_ quantity: Int, _ selection: VendingSelection) throws {
}
func deposit(_ amount: Double) {
}
}
