Need Help with iOS 17 Plugin Kit Crash - Stack Traces Included

Hello fellow developers,

I hope you're all doing well. I'm reaching out to this forum today in the hopes of getting some assistance with a rather perplexing issue involving the Plugin Kit crash on iOS 17. I've encountered the following stack traces, which seem to be at the core of the problem:

Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: RUNNINGBOARD 0xdead10cc

I'm encountering a crash in a custom keyboard app that occurs exclusively on iOS 17 and later versions. Unfortunately, I've been unable to reproduce this issue in a debug build. The crash logs indicate a SIGKILL with termination reason "RUNNINGBOARD 0xdead10cc." Any insights or guidance on debugging this issue would be greatly appreciated.

If anyone has any insights or suggestions on how to troubleshoot and resolve this issue, I would greatly appreciate your input. I've been trying to debug this on my end but have hit a roadblock, and your expertise could be invaluable.

Thank you in advance for your time and assistance!

  • +1 to this issue. I am working with a couple of different app developers who are getting the same problem.

0xdead10cc is your key, and there are probably other key clues in background threads regarding dead file locks, such as threads that are clearly doing file or database work. Please see our crash report documentation for the definition of 0xdead10cc and some things you can do.

  • @edford, thanks for sharing the documentation. We have gone through the docs, suspected some pod dependencies (ex: Firebase), removed the dependencies all together, and the crash still happens on TestFlight. Crashlytics itself does not report the crash either. The app or the keyboard extension do not use any database or CoreData; we are investigating file locks. The other threads on the crash report do not point to our code, similar to this one: https://developer.apple.com/forums/thread/738190

  • Found that after setting system bold on iOS17, a crash must occur every time you enter a new host

I'm encountering this with my photo editing extension, exclusively with iOS 17.0+. This app was last built with the iOS 16 SDK.
