iOS Build a Vending Machine App in Swift 2.0 Using the Vending Machine Testing Out the Vending Machine

Why is quantity a double rather than an int?

There are no cases when you are going to return a fraction of a vending machine item, so why does Pasan use a double for quantity?

Not sure if you figured this out yet. If so ignore

The initial file ("VendingInventory.plist") where he is pulling the raw data from has the quantity as a double (10.0...etc). Therefore for every instance of quantity thereafter he mirrored or matched the type.

Hope this helps.
