Crash Report iOS

I have made distribution build for my customer and after customer tested it he got this crash reporter below, but I don't understand this exception log, because here are not any issue with my methods and the last string says about CoreFoundation issue. How can I track this issue. Maybe will be better get from customer step to reproduce instead of crash log or may be I don't see something important in this log.

Open your project. GoTo Edit Scheme > In the left side bar Select Run "YourApp.app" > Now select Diagnostics Tab > Under Memory Management - Enable Zombie Objects.

When you run you app and it crashes during Zombie mode, you will get the proper error message and the exact place where the program crashed.

Hope this helps.
