Hi @ad-Jun, thanks for opening this issue.

Could you please:

  • Provide the following the full symbolicated crashlog
  • Describe what is your use case and what APIs you are using
  • Share any reproduction steps and verbose logging if you are able to reproduce this issue in your local environment

All of these will help us identify and root cause this crash.
Thanks!

Thanks for providing the crashlog.
Could you also tell us which IoT APIs you are using? So we can debug that use case and try to identify what could be causing your issue.

Thanks!

Actually I don`t know which Iot APIS cause the crash. It looks like it happened when AWSIoTStreamThread dealloc.

I meant which APIs you are calling in your code.
For example, are you connecting using AWSIoTDataManager.connect(withClientId:cleanSession: certificateId:statusCallback:), AWSIoTDataManager. connectUsingALPN(withClientId:cleanSession: certificateId:statusCallback:), or AWSIoTDataManager. connectUsingWebSocket(withClientId:cleanSession:statusCallback:)?.

I guess you're also calling AWSIoTDataManager.subscribe(toTopi:qos:messageCallback:)?

Knowing this might help us diagnose the issue. Also, please enable verbose logging in your local environment:

AWSDDLog.sharedInstance.logLevel = .verbose
AWSDDLog.add(AWSDDOSLogger.sharedInstance)

And please share the logs with us whenever a crash happens. I understand you said it happens infrequently, but it will be very helpful to have verbose logging once it does.

Thanks!

We've release some IoT improvements in version 2.36.7.
Could you please upgrade your dependency and check it out?
