sender.value (UIStepper) does not reset

Hey there, just had a look at the official download.

This seems to be a bug indeed. In order to also reset the stepper, you could create an outlet for your stepper. That is, the stepper itself, not the action. Just as with the other elements before, CTRL - click the stepper in storyboard and connect it to your view controller.

@IBOutlet weak var stepper: UIStepper!

This way, you can access the stepper and its' value directly. Then, in the reset() function, you could also reset the stepper value. Before, only the label was updated, but not the stepper value, just as you said.

func reset() {
    quantity = 1
    stepper.value = 1 // Reset the stepper 
    updateTotalPriceLabel()
    updateQuantityLabel()
}

Hope that makes sense :)

Pasan Premaratne, I did not follow that course, maybe this is worth mentioning. If it's up to the students to fix the little things, than probably not ;)
