Understanding the Crash Log - ios

Question

I am an Android Developer and trying some dummy for the iOS development.
I am trying a tutorial for AMSlideMenu and it was working well at a certain point of development.
I followed the complete tutorial and it worked well. After sometime while I was experimenting some other functionality the code breaked.
I undo and reverted back the changes but something still looks wrong.
below is the crash log, but i cant understand what went wrong

Answer 1

Looking up from the top (0) entry the last of your methods is: Pranshu1 so you need to look there.
The last method is: -[UIViewController shouldPerformSegueWithIdentifier:sender:]
so it looks like you are performing a Segue, check the identifier.
Before that is the method AMSlideMenuMainViewController so it looks like you are probably using the 3rd party code AMSlideMenu, check for correct usage.
Here is how to catch the exceptions at the point of the error:
To see the actual statement that is causing the error add an exception breakpoint:
From the Main Menu Debug:Breakpoints:Create Exception Breakpoint.
Right-click the breakpoint and set the exception to Objective-C.
Add an action: "po $arg1".
Run the app to get the breakpoint and you will be at the line that causes the exception and the error message will be in the debugger console.
Creating the breakpoint example:
