How to get the information from 'first throw call stack' in Xcode

Question

I got a crash from my client，As shown below

How can I figure out where the problem is from this picture？ How to get information from this? What does '+1036' mean behind '[__NSDictionaryM setObject:forKey:]'?

some where in your app `nil` is getting store in `dictionary` that is not allowed I mean its invalid data to store in dict. — Mahendra, May 21 '18 at 07:13

You can add an All exception break point in X-Code. Please follow the steps below.

Now run your code. This will hit your error point on code. And this because, you are trying to set a null key on a dictionary. After you add the all exception break point you can find the exact line.
