In default viewer its not possible to load PDF due this error.

  GlobalWorkerOptions.workerSrc =
	'https://cdn.jsdelivr.net/npm/[email protected]/build/pdf.worker.min.mjs';

The issue template asks you to check https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#faq-support, which tells you that the legacy build must be used in Safari.

Did you try loading https://mozilla.github.io/pdf.js/legacy/web/viewer.html in Safari?

Demo links works both but when I downloaded files and use in my webserver and trying to load PDF, first I get warning follow by an error. I have no idea what is difference between demo page and released files for download. All other browsers works fine, even on iPad with Safari. Only iPhones does not load PDF, UI is loaded.

<object id="pdfjs" type="application/pdf" data="/wcsfiles/mobile/plugins/pdfjs/web/viewer.html?file=&amp;locale=en#page=1" style="width:100%;height:72vh; -webkit-overflow-scrolling: touch;"></object>"

And with jQery i just setting data which contains path to pdf.
