Hi, i'm currently designing a "backup to icloud" solution for my app, and i was wondering what were the limits regarding : the maximum number of files in a given directory in APFS (not just the theoretical limit, but also the one that's handled decently by APFS on an iOS hardware) the maximum number of files in a given directory that's synchronized on iCloud (there again, the limit at which it starts to slow iCloud so much it becomes a really bad idea).

My use case : i want the app to completely silence a given received alert push notification, based on information the app has locally (completely remove it, and never even display it. Not just change the sound or badge). So far i found no way of doing that : notification service extension doesn't let you remove the notification entirely, just change its content. Using "background / content" notification type then creating the notification locally doesn't work, since "background" notification type is unreliable by design. voip notifications are banned from being used as a general-purpose background notification mechanism since iOS13 Help would be greatly appreciated.
