Why doesn't Font Awesome 5 work in safari on Ios?

Question

css

Hello.
Why fontAwesome 5 might not work in safari on ios?
I included css

<link rel="stylesheet" href="css/fontawesome-all.min.css" type="text/css">

Works in all browsers but not in safari.

.owl-prev:after,
.owl-next:after {
  font-family: FontAwesome;
  font-size: 2.5rem;
}
.owl-prev:after {
  content: "\f104";
}
.owl-next:after {
  content: "\f105";
}

I added optimizeLegibility (I didn't find such a solution) but it doesn't work for me. What could be the problem? Thanks
text-rendering: optimizeLegibility;

Problem solved. I just did not understand why all other browsers work fine with the previous code.
Maybe someone will come in handy)

.owl-prev:after,
.owl-next:after {
  font-family: 'Font Awesome 5 Free';
  font-size: 2.5rem;
  font-weight: 900;
}
.owl-prev:after {
  content: "\f104";
}
.owl-next:after {
  content: "\f105";
}
