iOS Build a Vending Machine App in Swift 2.0 Using the Vending Machine Updating the Quantity

Quantity stepper should have been reset to 1

QuantityLabel and variable reset right but in additional we must reset stepper's value as well. So we need to declare an IBOutlet of stepper and reset the stepper to 1 in the reset method

reset method should be look like:

 func reset() {

        quantity = 1
        quantityStepper.value = 1

For anyone trying to do this and a little confused (like I was), this is what adding the IBOutlet should look like:

@IBOutlet weak var quantityStepper: UIStepper!
