Crash reports for Unity embedded into iOS

We have a Unity game embedded into iOS(which means we have some other iOS parts than Unity). But we got a lot of crash reports which seems related to Unity layer. The following is a crash report stack log from Flurry. I was wondering if someone had the same problem before or had idea about what is happening here. Thanks.

Hi,

unfortunately I cannot answer your question. I would be interested in your approach on how to catch possible crash reports of the embedded unity application within another main program (an iOS application in your case).

The use case being lets say the embedded unity part crashes hard but you want to retrieve some information about this crash to for example to visualize them within your main/host application (e.g. the iOS app) and to include them into the log file of your main (iOS) program.

Do you use something like this or have any experience with this?

Best regards
