title: ionic-native/file + ionic-native/http download not working
body: <p>Using code from this answer <a href="https://stackoverflow.com/a/63585081/7751910">https://stackoverflow.com/a/63585081/7751910</a> and can't get it to work.  Don't have physical ios device, so using Xcode simulator.
  This is my code with console.log()'s:</p>
  <pre><code>public downloadFileAndStore(fileUrl: string): void {
  
  let filePath: string;
  
  if (this.platform.is('ios')) {
    filePath = this.file.documentsDirectory + this.getFileName(fileUrl);
  } else {  // for iOS use this.file.documentsDirectory
    filePath = this.file.dataDirectory + this.getFileName(fileUrl);
  }
  
  this.nativeHTTP.downloadFile(fileUrl, {}, {}, filePath).then((response: any) =&gt; {
     // prints 200
     console.log('download success', response);
     for (const key in response) {
       if (Object.prototype.hasOwnProperty.call(response, key)) {
         const element = response[key];
         console.log(key);
         console.log(element);
       }
     }
  }).catch((err: any) =&gt; {
      // prints 403
      console.log('download error', err.status);
      // prints Permission denied
      console.log('download error', err.error);
  });
  </code></pre>
  <p>}</p>
  <p>And here is the output I'm getting in Xcode console when I try to call the method:

  <p>But nevertheless nothing is downloaded.</p>
  <p>Upd: on real device doesn't work either</p>
