An iOS 11 bug might crash your iPhone on December 2nd

A bug in iOS 11.1.2 is causing iPhones to crash repeatedly once the clock hits 12.15am on December 2nd. As noted by iMore and Twitter engineer Yoshimasa Niwa, the bug appears to be related to third-party apps that use recurring local notifications for things like reminders.

Affected iPhone users have been turning off notifications or setting the date back to a time before December 2nd, but Apple has now released a fix. iOS 11.2 has been released just hours after this issue was discovered, and includes a fix for this date bug. Apple officially recommends installing this update, or disabling app notifications as a method for fixing the crash.
