FoodVendingMachine does not conform to protocol

Hi,

Currently working on the Vending Machine App and I'm struggling to get a protocol to conform.

Error message comes up Use of unresolved identifier FoodVendingMachine, also the self.vendingMachine part of the code does not appear in blue text like in the tutorial.

Here is a snippet of the code.

let vendingMachine: VendingMachine

required init?(coder aDecoder: NSCoder) {
    do {
        let dictionary = try PlistConverter.dictionary(fromFile: "VendingInventory", ofType: "plist")
        let inventory = try InventoryUnarchiver.vendingInventory(fromDictionary: dictionary)
        self.vendingMachine = FoodVendingMachine(inventory: inventory)
    } catch let error {
        fatalError("\(error)")
    }

    super.init(coder: aDecoder)
}

Snippet linking to VendingMachine protocol in the main code.

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)

}

Any help would be appreciated in resolving this.

Regards

Keir
