Hi, I hope you can help me. I’m sharing my two classes and a screenshot showing the ‘Add a new list’ screen as well as the storyboard highlighting the static table. Why can’t I see the table with the textField? What did I miss?

geeez 
you are right… thank you! I guess I never forget to do that when I am dealing with static cells.
