iOS 11.1.2 December 2nd Crash Loop

Juli Clover, for MacRumors:

A date-related bug in iOS 11.1.2 appears to be causing iPhones and iPads to continually crash or respring when time-based local notifications are received after 12:15 a.m. on December 2, according to reports on Twitter and reddit.

The problem seems to be tied to local notifications received from apps that offer daily or repeat reminders. For example, meditation app Headspace, one of the affected apps, sends daily reminders to users to encourage them to take some time to meditate. Any app using local (as in not pushed from a remote server) notifications that repeat will cause a crash.

I am intrigued as to what is tying December 2nd and repeating local notifications1 together to cause this issue. Regardless, along with #iamroot, this is yet another embarrassing bug for Apple.

Update 2017-12-02: Here’s an oddity: a major point release of iOS being made available on a weekend. It’s probably got something to do with this bug.

  1. I attempted to recreate the bug using a local notification from Todoist but it was unsuccessful, likely because it was a single notification. ↩︎
