InvalidType: Fatal Error

I'm getting an invalid type error when I run my code. I'm not sure of what is causing this. In the debugger, it says error = (VendingMachine.inventoryError) invalidType Thread 1: EXC_BAD_INSTRUCTION(code = EXC_1386_INVOP, subcode = 0x0) can anyone help me out :) Thanks

Edit: Heres my code

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 errror{
        fatalError("\(errror)")
    }

    super.init(coder: aDecoder)

}

oh my goodness! I can't believe my error was because I mistakenly named my enum cases "Poptart" instead of "PopTart". I Spent hours looking for this, but i'm happy now. lol, thanks

You dont post code so going by your first error: (VendingMachine.inventoryError) invalidType are you declaring this correctly?

yes I am. It says fatal error: InvalidType: file /Users/admin/Developer/VendingMachineStarterFiles/VendingMachine/ViewController.swift, line 31

this is line 31 catch let errror{ fatalError("(errror)") }
