Hi I'm still don't know why we only initialise the inventory in the protocol and why we don't initialise the selection and amount deposited in the protocol.? I know we initialise them later but why later in other code ?
protocol VendingMachineType { var selection: [VendingSelection] { get } var inventory: [VendingSelection: ItemType] { get set } var amountDeposited: Double { get set }
init(inventory: [VendingSelection: ItemType])
func vend(selection: VendingSelection, quantity: Double) throws
func deposit(amount: Double)
}
