Here is the code that I got help on previously on here, I just cannot quite tell what is missing for my code to work. I have it set up so a button is pressed to make the pickerview appear and then the choice appears in a label. But when I click on the buttons it does not make the pickerview appear. I guess from what I can tell, the issue is that I am missing a connection that would trigger one to make the other appear, my pickerview is set to hidden and also it appears over top a stackview when it should pop up.
