Oh such pain.
Ensure you select:
<ul>
<li>Copy file if needed</li>
<li>Groups (not references)</li>
</ul>
Here's one way to do it
<ul>
<li>Delete the reference to the file</li>
<li>Organise the files properly using Finder</li>
<li>Drag and drop the new files / folders back into Xcode</li>
</ul>
Then build. If you have build issues, do the following one at a time
<ul>
<li>Clean</li>
<li>Restart</li>
<li>Delete the entire derived data folder (go to <code>Preferences &gt; Locations</code> to find the path to the derived data folder)</li>
<li>If Xcode has lost references to your SDKs, then restart again. If this still doesn't fix it, then <code>File &gt; Swift Packages &gt; Resolve Package Versions</code></li>
</ul>
