Smartlook SDK version

1.8.3 Summary

Our users are suffering from different crashes on the Smartlook iOS SDK. We don't have good traces as they are hidden, but I'd love to add any kind of additional information that can help. Most of the crashes seem to be related to networking, some happen when there were no internet connection. I didn't manage to reproduce the crashes locally on my phone though

Hi @danibachar , thanks for the reports.

Although the cause of the crashes is indeed no clear from the reports, we are now working on a refactoring of parts of the networking-related code (we need to improve the internal business logic there) so the next SDK version may solve this issue as well.

Crashlog symbolication is now tricky for apps that are published in bitcode form, because the app is recompiled by App Store and the standard ways of getting crash reports readable do not work anymore.

The only way seems to be to use dSYMs from App Store - Smartlook SDK includes from the version 1.8.3 the necessary mapping files for bitcode (see Acquire Updated App Symbol Information from the App Store for more details if you are interested).

There is no exact ETA for the next version, but we would like to release it sometime later in January.

I have downloaded all the dsym Files from AppStoreConnect and uploaded it to Google Firebase Crashlytics. However, I still get the "hidden" log in the crashes.

Hi @danibachar , @Kondamon ,

new SDK version has been released.

It is a maintenance release that also aims to solve some of the crashed. Given the fact that there are ongoing issues with the crashes symbolication, we cannot guarantee we addressed all the crashes, however, we identified some patterns in them and fixed their causes.

New release version is 1.8.4, and it is available via Swift Package Manager, Cocoapods (pod Smartlook) and for direct download.

Thanks, @pavel-kroh-smartlook - will update on the fix

Hi @danibachar , we are closing this issue. If the crashes reemerge, feel free to reopen it or creating a new one. Thanks.
