Has anyone else been getting reports of their iOS app’s data just… vanishing? Specifically, it sounds like UserDefaults is being reset. This doesn’t seem to be hitting a lot of my users, but the ones it hits are seeing it over and over.

@adam Maybe @Catfish_Man knows? We've not heard anything where I work.

@jaredsinclair @adam I haven't worked on UserDefaults since 2018, but historically a leading cause of issues like this was "something causes the app to be launched before first unlock, when defaults aren't readable".

One other cause was cfprefsd running out of file descriptors, but that only happened once and I fixed it in a way that I think would be fairly difficult to re-break.

@Catfish_Man @adam I can't believe 2018 was SIX YEARS AGO.
