Date Bug in iOS 11.1.2 Causing Crash Loop on iPhones as December 2 Hits [Updated]

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.


On reddit, users have had some success fixing the issue by disabling notifications and turning off background app refresh, while Apple's support staff appears to be recommending a manual date change to a time before the problem occurred as a temporarily solution. Reinstalling apps and restarting does not fix the issue. The problem looks like it's limited to devices running iOS 11.1.2 -- devices on the current iOS 11.2 beta aren't affected.

Apple Stores in Australia, where it is late afternoon on December 2, are reportedly being inundated with support requests from customers who are experiencing the issue.


Apple will undoubtedly fix this problem quickly through an iOS update, but as people wake up on December 2 in the United States and other countries throughout the world, there's likely to be quite a lot of confusion when devices begin inexplicably respringing over and over again.

If you're experiencing continual crashing, the first thing to try is disabling notifications for apps that send regular reminders. It can, however, be difficult to tell which apps are responsible, so a secondary solution is to set the date on your iPhone to before December 2 as you await a fix from Apple.

If you aren't experiencing any crashes, there's no need to turn off notifications or adjust the date on your device.

Update: Apple has released iOS 11.2 to fix this problem, along with an accompanying support document outlining steps to take if you're experiencing crashes. Apple recommends turning off notifications and then installing the update.

If your device with iOS 11 unexpectedly restarts repeatedly on or after December 2, 2017, learn what to do.

Use these steps to turn off notifications for all the apps on your device, then update your device to iOS 11.2:
1. Tap Settings > Notifications.
2. Tap an app, then turn off Allow Notifications. Repeat this step for each app.
3. Update your device to iOS 11.2.
4. After updating, tap Settings > Notifications and turn Allow Notifications on again for each app.

The bugs in iOS 11 have been pretty embarrassing so far. The calculator being straight up wrong if you enter digits too quickly is my favorite and it’s still not fixed. lol

Apple is giving 90's-early 2000 Microsoft a run for their money. May as well call it macOS Vista and iOS ME.

Un-effing real.
Apple software is really going to the dogs.
Too bad nobody in the upper echelons seem interested in top quality software anymore.
Time to clear these old, rich clowns out and get some enthusiastic new blood in.
