VendingSelection cannot be constructed, it has no accessible initializers

Here is my InventoryUnarchiver class. This error of "VendingSelection cannot be constructed because it has no accessible initializers" occurs on the "guard let key = VendingSelection(rawValue: key)" line.

    var inventory: [VendingSelection : ItemType ] = [:]

    for (key, value) in dictionary {
        if let itemDict = value as? [String : Double], let price = itemDict["price"], let quantity = itemDict["quantity"] {
            let item = VendingItem(price: price, quantity: quantity)

            guard let key = VendingSelection(rawValue: key) else {
                throw InventoryError.InvalidKey

            inventory.updateValue(item, forKey: key)
    return inventory

Change enum VendingSelection {} to enum VendingSelection: String { }
