Detect IOS Device and Display Button only if on IOS

Only by custom code
https://stackoverflow.com/questions/9038625/detect-if-device-is-ios

First use alert() to check if the code works fine.

WEBFLOW: Show the button on webflow (Otherwise its hard to edit/style the button). Add to this button some class (to select by Jquery - for example: download-now-button).

And hide by js (if not ios - hide the button):

<script>    
 if (!ios) {
         /* select the button by class name and hide */
        $('.download-now-button').css("visibility", "hidden");
  }
</script>

I never try this - but it should work fine (also search for codepens)
