Swift - Warning when editing text fields and tapping buttons - ios

Question

I have a scroll view that adds UI elements programmatically, but a button that I've added seems to have a delay in response once tapped both in a simulator and on an iPhone 7 Plus I use to test on it. I'm not sure as to why. I also am getting warning messages each time a text field is edited as well. How do I resolve these issues? Below our the warning messages and some of my code.
Thank you for helping!
