title: Launch screens may not set custom classnames
body: <p>I tried to add a custom class to my Table View Cell, but after I added it it gives the following error:</p>
  
  <p><a href="https://i.stack.imgur.com/HbBVgm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/HbBVgm.png" alt="enter image description here"></a></p>
  
  <p>I often read that I can't use custom classes in the LaunchScreen but I haven't touched this file. Can anyone help me? </p>

  <p>This are my general settings for the main and the launch interface.</p>
  
  <p>I am using Swift.</p>
