I've been struggling to find a progressive web app (PWA) that works fully offline on an iPhone for quite some time now. This is pretty much my last hope. I've searched everywhere online, including Stack Overflow, but haven't gotten any helpful answers yet.
I'm aware that offline support for iPhone PWAs can be tricky, but it's definitely doable. The app I'm building is supposed to function as a reference tool for my job, which can often be in areas without service, so it needs to be completely offline. If there's an alternative route that doesn't require me to learn Swift or Objective-C, I'd be open to exploring that!
Currently, my setup registers a service worker on the first load and restricts it from pulling in other sources. This has been fine on my Windows laptop, but when I transfer it to my phone, it just doesn't work. I've tried numerous approaches, and I'm at my wit's end!

I actually have a working one you might find useful! Check it out: [Chess Chrono PWA](https://bitobeats.github.io/chess-chrono/). It's been really helpful for offline access!
iPhone PWAs function similarly to those on other platforms, but they tend to clear data if they haven't been used for a while. You mentioned needing to manually unregister the service worker every time you update it—this shouldn’t be necessary. It should automatically detect and register the new service worker.
Using Workbox could really enhance your offline capabilities. Make sure to follow the guidelines carefully since caching can be tricky. If you’re not cautious, you might run into issues down the line.
That's awesome! Glad to hear it works for you! Just curious, was this PWA made with any AI tools?
