Describe the bug I have some new crash in my Crashytics dashboard

To Reproduce I can reproduce the error, I only see it in my crashlytics logs.

It appear on various OS and Device (iOS 14 >).

Running on HaishinKit.swift 1.2.1.

Have you any idea how to fix it ? :)

Thanks !

I'm not sure. I can't reproduce it. Could you provide me of reproducible short sample code?

Hello @shogo4405

Unfortunately, I can't reproduce it... It happened at 2% of our users since we've compiled the app with the latest Xcode (13.3). It looks like the latest SDK has broke something, we didn't touch the streaming part of the app.

Hello,

Same issue :

I can't reproduce it, seems to be a random crash.

[shogo4405]

Could you provide me your UIViewController?

Sorry for the late reply, I can try but this is a complex application which can't work with sample project

Hello,

Look like there was an extra DispatchQueue in my code :

After removing, no more crash at this time !
