Cache Fetch fails on iOS

[crb04c]

The v3 of the tool doesn't seem to work properly on iOS. The cache load throws an exception and ends up always performing a network fetch. This breaks the ability to have an offline app.

Note: Using a simple service worker (one that doesn't do the redirect clean up/etc) does work properly.

Edit: It looks like setting the cache name to a shorter simple string seems to fix it as well.

var precacheConfig = <%= precacheConfig %>;
var cacheName = 'simple';

Looks like I have a similar issue, but @crb04c fix is working only temporary for me, i.e. on iPhone 8 plus (iOS 12) after hour app cannot be loaded in offline mode again, but on a second device, it's working for a long time. Maybe changing the name just updates data in cache and safari is removing some them again after some time, I don't know, just wild guess.

Edit: This bug is more related to this issue Bug 190269 - IOS 12 - Service worker cache not shared when added to homescreen
