服务工作者无法在IOS 12的离线模式下工作

Question

我正在尝试使PWA在iOS / Android OS的两种联机/脱机模式下均能正常工作，到目前为止，我已经准备好服务工作者并在android上工作，服务离线页面正确，但是在IOS上根本无法使用，我可以将PWA添加到主屏幕，并且可以使用我拥有的所有IndexedDB方法，但是一旦我脱机，它告诉我Safari没有互联网连接，我认为的安装方法可能存在问题我的服务人员，但是我不知道如何在iphone上检查它，因为我是在Linux上进行开发的，这是我的服务人员代码，可以在android上正常运行，但在IOS上无法运行。

这是在index.html上激活此类服务工作者的脚本

{% if browser_mobile %}
  if ('serviceWorker' in navigator) {
    window.addEventListener('load', function() {
      navigator.serviceWorker.register("{% url 'sw.js' %}")
      .then(function(registration){
        console.log('Registré el Service Worker: Paso a redirección',registration.scope);
        if (window.matchMedia('(display-mode: standalone)').matches) {
          var url = "{% url 'autentificacion:inicio' %}";
          window.location = url
        }else{
          console.log("This is NOT! running as standalone.");
        }
      })
      .catch(function(err){
        console.log('Falló la instalación del Service Worker: ', err);
      });
    });
  }
{% else %}

该服务人员有问题吗？有没有办法调试IOS服务工作程序安装？类似于chrome-dev工具？
