Small usability issue with the UIStepper

Just wanted to point out a small usability issue that we are left with when calling the reset() function. When we change the quantity using the stepper and then tap on a different item, the quantity label correctly changes back to 1, but the stepper's value is still set to whatever it was at before we called reset(). This is evident by the fact that both the - and + are available to tap. In fact, if you click on the - after reset() is called, it will step backwards from wherever we left off.

To fix this, we need to set the stepper's value back to 1. However, as the code currently sits, we are unable to do this, because we did not create an outlet for the stepper in our view controller. If we create that outlet and then add a line in the reset() function to set the stepper's value back to 1, the issue is solved.

Hope this was informative! Carry on!!

I was just noticing that towards the end of the video and came here to see if anyone else had as well. That's the same solution I was thinking of doing.

This post didn't necessarily need an answer (there wasn't a question), but I'm making this the answer and marking it best so as to stop getting reminded that I need to select a best answer... :)
