    Description

      The following code fails to access certain information such as file size and mime type on iOS simulator.
      This works fine with an actual device.

      Sample project is attached : qtbug90844-sample.zip
      NSPhotoLibraryDescription is defined in Info.plist.

      Code

         QMimeDatabase md;
 
   QString dir = QStandardPaths::standardLocations(QStandardPaths::PicturesLocation).last();
   QString selectedFile = QFileDialog::getOpenFileName(&window, "Select image", dir);
   qDebug() << "Selected file: " << selectedFile;
 
   QFileInfo info(selectedFile);
   qDebug() << "Exists: " << (info.exists() ? "true" : "false");
   qDebug() << "Filename: " << info.fileName();
   qDebug() << "Path: " << info.path();
   qDebug() << "Size: " << info.size();
   qDebug() << "Mimetype: " << md.mimeTypeForFile(info);

      Actual result 

      [4785:52808] Selected file:  "assets-library://asset/asset.HEIC?id=CC95F08C-88C3-4012-9D6D-64A413D254B3&ext=HEIC"
