Crash logs code 0xdeadfa11 and reason SPRINGBOARD, killed from app switcher

We've suddenly (in the last few days) started receiving a significant number of crash logs for the released version of our app (built with Xcode 8 against the iOS10 SDK) where our app is being used with iOS 11.1 beta.


There doesn't seem to be a pattern to the devices used (apart from the iOS 11.1 version number), and the stack trace of the crashed thread doesn't show anything in our application code other than our main() method.


However, there are some interesting "Termination reason" entries:


Termination Reason: Namespace SPRINGBOARD, Code 0xdeadfa11

Termination Description: SPRINGBOARD, killed from app switcher | | ProcessVisibility: Background | ProcessState: Suspended


or


Termination Reason: Namespace SPRINGBOARD, Code 0xdeadfa11

Termination Description: SPRINGBOARD, Shutdown (<SBShutdownContext:0x1c3827320 - reason:'Powerdown UI'; fromUserPowerDown:YES>) | | ProcessVisibility: Background | ProcessState: Suspended


Does anyone know what these might mean?

The 0xdeadfa11 is the error code for when the user force quits the app.

I’d guess the second is similar (your app’s process was killed) by the user turning the device off.

So nothing to worry about in that case...but why are we suddenly receiving crash logs for this situation when we never have in the past? It only creates more crash logs to look at without there being a problem to address.

I see the same with my app. I got few crash reports in recent days. All of them from iOS 11.1 beta 2 (15B5078e).

My app built with XCode 9 and iOS 11 SDK.


They crash at libsystem_kernel.dylib: mach_msg_trap + 8.


Exception Type: EXC_CRASH (SIGKILL)

I'm seeing this as well across devices on 11.1. It's not an exorbatant amount of crashes but it's definitley higher than we're usually accustomed to. Going to file a bug with Apple about it, since all of the crashes are running Beta 2.

Yes, we are seeing a huge spike of these too.


I hope this is a mistake, because it will add a lot of noise to the crash stats, basically making the metrics in iTunes Connect useless.


Swiping apps away is a bad habit that is not going to go away. People do this for all kinds of reasons, not just when your app hangs.

Crash reports seem to stop occuring after iOS 11.1 beta 3 release. Probably this issue was fixed in it.

I'm seeing this crash as well across devices on iOS 11.2 and 11.3.


But its crash reason is that "Termination Description: SPRINGBOARD, power down shortcut | | ProcessVisibility: Background | ProcessState: Suspended",not app switcher switching.


This normal case that app closed power down why be considered crash ?
