[BUG] Offline mode not working on iPhone about pwabuilder HOT 6 CLOSED

@JuanCecenasJPGlobal activate the debug mode and try to inspect your cache storage. Which iOS version?

from pwabuilder.

@khmyznikov I've activated debug mode and have been inspecting the cache storage. Currently, I can see and access the Indexed DB, however, I'm not observing that the files are being cached. It seems like the application always attempts to fetch files from the server instead of utilizing the local cache. Could you provide guidance on how to address this issue? Additionally, the iOS version I'm conducting these tests on is 17.2

Same issue here!

Additionally, I came across some information suggesting that using reload or reloadFromOrigin instead of load might have an impact on caching. Could you confirm if this could be relevant to our issue?

Furthermore, I found some resources discussing how to activate cache mode in Swift. However, I'm unsure about how to implement or configure it in our app. Would enabling cache mode or implementing any specific steps help in ensuring the correct offline functionality of our application? It's worth mentioning again that the PWA works offline seamlessly on web and Android platforms.

Additionally, I came across a code snippet that uses navigator.storage.persist() to attempt to persist local storage in the browser. Although I've tried implementing it in my sw.js file, I receive an error message indicating that persist is not a valid function.

navigator.storage.persist().then(function(persistent) {
if (persistent)
console.log("Storage will not be cleared except by explicit user action");
else
console.log("Storage may be cleared by the UA under storage pressure.");
});

While I haven't been able to get it working yet, I thought it might be helpful to mention it here in case it provides any clues on how to address our caching issue in the iOS app.

Hello all!

I am going to ask that we move this discussion to our Discord https://aka.ms/pwabuilderdiscord as that is where we normally handle issues for our experimental iOS platform. Thanks all!
