Looks like Apple broke #CloudKit sync in OS 26.4. Remote notifications don’t seem to arrive, so no updates unless the app is relaunched. https://developer.apple.com/forums/thread/820550
iCloud Sync not working with iPhon… | Apple Developer Forums

I somehow assumed Apple would treat the #CloudKit bug as top priority without giving it a second thought, so I actually overlooked the phrasing the DTS engineer used in their post that @iandundas pointed out. Kinda crazy!
Good news! Based on my initial tests on iOS 26.5 beta and reports from others in the community, CloudKit sync seems to be working again.
@lukaskubanek @cdfinder @iandundas WTF?!? So, if you don’t file a bug report they will not (or only accidentally) fix it?

@jxrxme @lukaskubanek @iandundas

Well, Apple usually completely ignores my error reports anyway, but this is really a bad joke, Timmy!

@lukaskubanek @iandundas The last radar I ever filed was in 2019 after WWDC. An engineer helped me devise a workaround for an issue, which I much appreciated. His supervisor asked me to file a radar. Reluctantly, I did, and referenced the supervisor. Of course it came back as won’t fix, so a complete waste of my time. I wouldn’t mind the no pay if they actually fixed things. But yeah - do your own damn work.

My stats are not that bad - ca. 30% are taken care of, and in about 5% I am actually contacted personally. But it is a lot of effort to file a Rader as I do, because at least 50% of the cases, I am also trying to submit a complete mini project, that exposes the problem.

Perhaps it heals, that I know few people at Apple too.

@tuparev @provuejim I still file them from time to time but also collect them in a repo (https://github.com/structuredpath/AppleBugReports) so I can quickly check if they’re fixed on newer OS versions. It now takes much less time with AI support and it helps me find workarounds… But yeah, my stats are also pretty bad. It feels like only feedbacks pushed through Apple employees get attention if at all.

@lukaskubanek Apple is great at acknowledging "severe" and "immense" issues and then putting them into a drawer never to talk about them again. See the SwiftData background update issues that iOS 18.0 introduced, probably hundrets of devs reported and that is still around in 26.4 :|
