iOS Build a Vending Machine App in Swift Loading Data From a Resource Finishing Touches

VendingMachine.inventory not working in ViewController.swift

Ok so I went through the tutorial and around the 8:00 mark he goes into the ViewController.swift and has us write a print statement at the end of the init method, but I keep getting an error: 

Instance member "inventory" cannot be used on type "Vending Machine"

I can't get it my app to work from here. Can anyone help? My code Snippet is below.

    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)
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        setupCollectionViewCells()
        print(VendingMachine.inventory)

Hey Joe, I don't have the same error than you, when I copy/paste it in my code but I can see in this line

 let dictionary = try PlistConverter.dictionary(fromFile: "VendingInventory", ofType: plist)

that it should be 

let dictionary = try PlistConverter.dictionary(fromFile: "VendingInventory", ofType: "plist")

But I'm not sure it will solve you problem. Can you try it and tell me what's going on?

The "" around plist was correct! Thanks!
