Starter code doesn't have the required init

Just a heads up to Pasan. The starter code that I downloaded at the beginning of this course was different than you are showing. Specifically, the ViewController.swift file in the starter code I downloaded did NOT have the required init?() in it. I had to double check and redownloaded a fresh zip file and, sure enough, no init() in ViewController.swift.

I noticed that too. I had to jump through the video and pause at specific points to add the missing code to the starter files.

i.e. the required init? and the super.init lines of code.

This code snippet includes the missing lines of code and will get you up-to-speed for the end of the course.

let vendingMachine: VendingMachineType

    required init?(coder aDecoder: NSCoder) {
        do {
            let dictionary = try PlistConverter.dictionaryFromFile("VendingInventory", ofType: "plist")

            let inventory = try InventoryUnarchiver.vendingInventoryFromDictionary(dictionary)
            self.vendingMachine = VendingMachine(inventory: inventory)
        } catch let error {
            fatalError("\(error)")
        }
        super.init(coder: aDecoder)
    }

:dizzy:

Thanks. Yeah I had already gone back and added the code needed to finish the course. I should have added that to this post as well for others to get, but now that you have, others can get it!

Just one typo: Inside the do block, the function name that has been called for declaring "inventory" should be vending*InventoryFromDictionary, not **Invertory*.
