title: How to connect a button in storyboard to code in Xcode
body: <p>I have been coding since yesterday so this might seem like a stupid question:
  My app is supposed to be a shopping list app where users can write down whatever they want to buy, add a date and then the list can be saved and later opened and deleted. I created a User Interface and now whenever I am trying to control - drag it into the view controller, the window to create an IB outlet does not appear. There are multiple answers for similar questions on here but none actually answers my problem. 
  My questions are: How do I connect my button to code and how do I get the window to show up?
  Also, I would like to let the user delete one Textfield at a time so that they can keep the other part of the list. Do I have to connect each textfield to its own delete button?</p>
  
  <p>Every help or idea on how to fix this problem is much appreciated! 
  I hope the screenshots attached will help to understand my problem.

  This is how my UI looks. I managed to connect the Edit shopping list button to the second scene. Now I would like to connect the Button "save list" to code so that I could write code that saves the users' data.
  Whenever I try to link it, nothing shows up. Do I have to set an IBoutlet first? and how would I do that?</p>
