iOS 8 crashes in UVManager.m which is not one of my classes

Question

I am seeing quite a few crash reports in Crashlytics for one of my apps. All crashes have occurred in iOS 8, non jailbroken on both iPad and iPhone.

The crash report points to a class called UVManager.m however I cannot find a class with this name in my code at all. So it is either included in an attached library that I use, or part of the iOS 8 frameworks.

How can I find out where the problem lies or what framework is causing the problem?

The crash is:

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0x0000000000000010

Here's the crash log:

Answer 1

Are you using AppSee? I believe the UVManager is part of their SDK
