title: Unassigned image
body: <p>I am having a problem loading some images, and I think <code>assets.xcassets</code> is the problem. Some of these images show up like this:</p>
  
  <p><a href="https://i.stack.imgur.com/8HsaE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8HsaE.png" alt="enter image description here"></a></p>
  
  <p>It says that this image is unassigned, but I have assigned it to be a tab icon. Now, the image isn't even shown in the tab icon. How can I get it to show again?</p>
