Hi @eugeneego

We've tried to reproduce the crash on our end but haven't been able to. Are you able to reproduce this yourself? If yes, do let us know the steps to reproduce the same.

Additionally, could you confirm if the crashes are happening on the iOS platform and not on macOS, watchOS, and tvOS?

Hi, we are also starting to see same crash in new version of our iOS App with similar stack trace. We also couldn't reproduce it yet.

As far as I can see from beginning of the phased release, it seems it's only happening on iOS 16.1.0

[uerceg]

@eugeneego @dede Just to double check, do you guys have StoreKit.framework linked to your app?

[akbashev]

Also seen an issue. So far just one user, iOS 16.1.0, iPhone 11. Adjust sdk version 4.33.1 . We do use StoreKit to call SKStoreReviewController.

@eugeneego @dede Just to double check, do you guys have StoreKit.framework linked to your app?

Yes, our app is linked to StoreKit.
The crash is only on iOS 16.1.0, no crashes on iOS 16.1.1. Probably it could be an iOS issue with new API availability that fixed in 16.1.1.

@eugeneego Thanks for the response. Yeah, this is really awkward and even though we have also read about "some bug" which Apple has fixed when it comes to SKAdNetwork with iOS 16.1.1 release, we saw nothing inside of their iOS SDK source code which could indicate that the bug was that updatePostbackConversionValue:coarseValue:lockWindow:completionHandler: method was not being present on iOS 16.1.0 devices. Even their docs are not stating anything about iOS 16.1.1 exclusivity for that API. Nonetheless, we will ship an update soon with a bit more mechanisms to check whether SKAD API we want to invoke is truly present on the device which should hopefully eliminate cases which (like mentioned above) we were unfortunately unable to reproduce on our end.

Maybe one more question - do you see these crashes happening for your entire iOS 16.1.0 user base or just some of the users with that specific iOS version?

[eugeneego]

@uerceg As I see in our analytics, we have minor audience on iOS 16.1.0, and we've released fix with reverting SDK to 4.32.1 quickly, so can't really tell about it's affected our entire iOS 16.1.0 user base.

Maybe one more question - do you see these crashes happening for your entire iOS 16.1.0 user base or just some of the users with that specific iOS version?

@uerceg it's only happening to a small amount of iOS 16.1.0 users. Our Adjust SDK version was 4.33.0 in that release.

Hey guys. We just shipped 4.33.2 patch version update where we tried to address these occasional crashes in iOS 16.1.0. In case you get a chance to give it a shot, please feel free to and let us know if you're still facing this issue with that (or later) SDK version. Looking forward to hearing back from you.

[uerceg]

Closing this one for now, but in case you still see the issue happening post this SDK update, please let us know and feel free to comment / reopen. Cheers.
