Hi @ishch ,

thank you for detailed technical report.

We investigate it, however, as the crash reports could not be symbolificated (it is not possible to do locally for bitcode releases) it is not straightforward to find the crash causes.

In any case, we plan a maintenance release in few days, we try to fix whatever we are able to do till then, and include the necessary symbolification data for more verbal future crash reports.

[pavel-kroh-smartlook]

Hi @ishch , Smartlook iOS SDK 1.8.2 has been released.

We attempted to address the issues there, but we cannot reproduce them and without full symbolification of the crash reports it is hard to find their causes. Thus, we also decided to add symbolification maps to the released SDK so the next crash reports will provide better information for us to debug the issues.

[pavel-kroh-smartlook]

Thanks a lot, @ishch ! Now we have much better idea what is the issue, fixing is in progress and we plan to release it in a week or so.

[pavel-kroh-smartlook]

Hi @ishch , new 1.8.3 version of iOS SDK is released.

We addressed there all the issues you reported.

Thank you for your help with documenting and reporting them.

[SenNeonoveNoci]

@ishch I hope all your issues are resolved. I'm closing this issue, but if you experience any issues feel free to reopen it.
