PDFs (maybe all files?) not opening in iOS 13

[ddl2829]

Expected Behaviour

I have been generating and viewing PDFs in my apps using this plugin and cordova-plugin-file for quite some time. I was expecting this workflow to continue working as-is with the newest iOS update.

Actual Behaviour

After updating to iOS 13 documents no longer load.

Reproduce Scenario (including but not limited to)

Non functional both in iOS simulator and on actual device.

Steps to Reproduce

1. Write a PDF file to the application's Library folder.
2. Attempt to open the file with this plugin.
3. Observe white screen as pictured above.

Sample Code that illustrates the problem

//pdf is a JSPDF object
const pdf = this.get('pdf');
window.requestFileSystem(1, 1024 * 1024 * 1024, function(fs) {
  console.log('Local file system granted');

  fs.root.getFile('temp.pdf', { create: true }, (fileEntry) => {
    console.log('got file handle');
    fileEntry.createWriter((fileWriter) => {
      console.log('file writer made');
      fileWriter.onwrite = function() {
        console.log('file done, opening ' + fileEntry.toURL());
        cordova.plugins.fileOpener2.open(
          fileEntry.toURL(),
          'application/pdf',
          function() {}, //success
          function() {} //error
        );
      };
      fileWriter.onerror = function(e) {
        console.log('Write failed: ' + e.toString());
      };
      console.log('writing output');
      fileWriter.write(pdf.output('blob'));
    });
  });
});

I appear to have done a poor job testing this- the issue in fact appears only in the simulator, which I can live with.

I feel like this issue is worth opening. Using file-opener2 2.x it was working on the simulator. Thankfully I checked on the device because of your comment. It is indeed only affecting the simulator.

I am having this same issue on the device with iOS 13.3.1 - it is showing the Quick Look framework (photo above) instead of opening the file in the appropriate application on the device (PDF, PPTX, etc)
