title: Adding sections in a grouped table view in Xcode
body: <p>My code is a little different to others, but it works. </p>
  
  <p>I am new to app coding, but I would like to add some of 
  these into sections:</p>

  <p>So some of them have their own group with a small title to each.</p>
  
  <p>But my code looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/ZMpaZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZMpaZ.png" alt="enter image description here"></a></p>
  
  <p>and I don't know what to insert to do it right. </p>
  
  <p>(The bottom half of that picture is the pictures in the detail view, that shows up in the detail view when you select something from the table view.)</p>
  
  <p>(I know Xcode shows errors in my code, but it still works. )</p>
  
  <p>Can anyone help me?</p>
