title: Downloading a blob on mobile iOS Safari/Chrome
body: <p>I am trying to download a PDF that is in a blob format on iOS.  It works as expected on Desktop/Android, but does not work as expected on any browser on iOS. Does anyone have any insight as to why this does not work?</p>
  
  <pre><code>export function setBlobtoLink (url, fileName) {
    const xhr = new XMLHttpRequest();
    xhr.open('GET', url, true);
    xhr.responseType = 'blob';
    xhr.setRequestHeader('Content-Type', 'application/pdf');
    xhr.onload = function xhrOnload () {
      if (this.status === 200) {
        if (window.navigator &amp;&amp; window.navigator.msSaveOrOpenBlob) {
          window.navigator.msSaveOrOpenBlob(this.response);
        } else {
          const data = window.URL.createObjectURL(this.response);
          const link = document.createElement('a');
          document.body.appendChild(link);
          link.style.display = 'none';
          link.href = data;
          link.download = fileName;
          link.target = '_blank';
          link.click();
          window.URL.revokeObjectURL(data);
          link.remove();
        }
      }
    };
    xhr.send();
  }
  </code></pre>
