Hi everyone,
I'm experiencing a crash in my iOS app and would appreciate some assistance in diagnosing the issue. The crash report indicates a SIGABRT (signal 6, abort trap) caused by an abort() called in the main thread. Here are the relevant details from the crash report:
Application Specific Information:
scss
abort
Kernel Triage:
sql
VM
Thread 0 Backtrace:
scss
0
The crash seems to be related to a VM allocation failure (mach_vm_allocate_kernel failed within call to vm_map_enter). I suspect it might be due to a memory allocation issue, but I'm not entirely sure how to pinpoint the exact cause.
Additional Information:
Has anyone encountered a similar issue or can provide guidance on how to resolve this? Any insights or suggestions on how to debug this would be greatly appreciated.
Is there a way to catch the runtime error in Maui or is there a known issue?
Thank you in advance!
Update
All versions of used software are up to date. My apologies we are using Maui. I have tested on all devices locally and through testflight. The crash only happens on apples testers side.
We are currently on .net7 and we are using the Scandit.DataCapture.Barcode nuget. I have tested on lower versions as well and we seem okay. The issue seems to not happen for any of the dev team on any device just when apple is testing. We can not replicate the bug.

The app is built using Xamarin.
I see the tag is MAUI, is your project a Xamarin.Forms project? Or a MAUI project?
iPhone OS 17.5.1 (21F90)
Please test if this issue occurs on iOS17.2 devices (or lower than iOS17.2)In addition, I understand that you are testing on your physical devices, so what's the Xcode version on your Mac?
@Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) All versions of used software are up to date. My apologies we are using Maui. I have tested on all devices locally and through testflight. The crash only happens on apples testers side. Thank you for your response - looking forward to hearing back from you
I got it. You are using Xcode15.4.
What's the detail MAUI version(.net6/7/8)?
The app uses the Scandit SDK for barcode scanning.
Is this Scandit.DataCapture.Barcode NuGet? Do you have the same issue on iOS17.2 devices (or lower than iOS17.2)?
Yup thats the version. We are currently on .net7 and we are using the Scandit.DataCapture.Barcode nuget. I have tested on lower versions as well and we seem okay. The issue seems to not happen for any of the dev team on any device just when apple is testing. We can not replicate the bug. The app was successfully launched on Android.
.NET7 is not supported, it's recommended that you update to .NET8. As Bruce said, you could test on a m1 iPad with iOS17.5 to reproduce the issue.
Note: it's not clear if that third-party package you referenced uses new API of iOS17.5(some new APIs are not supported with MAUI), please contact the owners for further help
Do you reproduce the issue on your physical device?
I have not heard from you for a couple of days. Please let me know if there is anything that I can help here.

iPad 13,16 is a m1 iPad. You should test your code on a m1 iPad. also .net 7 is out of support.
