Detect array with issue (Debug mode)

My app is crushing when i'm calling a few methods

I can see the error message and I understand what it say but I don't know how to detect the array with the problem by the message. I have lots of arrays in the project. how can I know from where the problem come from?

this is the message:

To handle All exceptions, From Xcode click on Show the Breakpoint Navigator

Click + button at bottom side and from pop up click on Add Exception Breakpoint.

enter image description here

This will add exception break points for application, try to run again and execution will stop if any runtime exception raised.

If this will not help, enable zombie environment for project, check out from this thread -
