It seems I can’t use the Service Worker API, or at least not on iOS. Am I missing something?

This is what it shows in the XCode debugging console:

APP ACTIVE
⚡️  [warn] - Service workers are not supported.

I’m just curious, how to you go around this? Say I want to use service worker cache to pre-cache some API requests, how would I do it with Capacitor? Emulate it with Storage/localStorage? Any better options?

As of iOS 14, Apps opting into App Bound domains (https://webkit.org/blog/10882/app-bound-domains) now do actually get service worker support in WKWebView. They’re not advertising it broadly yet, but it’s supported: https://twitter.com/othermaciej/status/1295434201865412608
