title: Files App/FileManager: App folder is hidden and files in Documents folder can be read but not deleted
body: <p>I think it's an old bug and it has not been fixed: App Folder (Documents folder) does not show in Files App.</p>
  <p>(UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace in info.plist are true)</p>
  <p>There was a workaround to make the app folder appears in Files app again: Restart device or simulator.</p>
  <p>But this trick doesn't work any more after I updated to XCode 13 and run simulators in iOS15.</p>
  <p>I can read files in the Documents folder from the app, but unable to delete or trash them. If I trash a file in the Documents folder, this error will appear:</p>
  <pre><code>Error Domain=NSCocoaErrorDomain Code=4101 &quot;Provider returned unsupported error&quot; UserInfo={NSUserStringVariant=Trash, NSURL=file:///Users/***/Library/Developer/CoreSimulator/Devices/***/data/Containers/Data/Application/***/Documents/file.zip, NSDebugDescription=Provider returned unsupported error, NSUnderlyingError=0x600001b93270 {Error Domain=NSFileProviderInternalErrorDomain Code=3 } ...
  </code></pre>
  <p>However, I still can open the Documents folder from simulator with MacOS Finder and delete files from there.</p>
  <p>I believe this happens in production too because many users reported sometimes they can't delete files in the app.</p>
  <p>I would like to know if there is a solution for this problem</p>
