NSRangeException at particular Segue

I have this particular segue that keeps giving me NSRangeException. I have no code at all in prepareForSegue. I put a break point in viewdidload of that view controller and it is executed with no problem. Seems that the exception occurs in IOS system code.

This is detail of exception

Please put exception breakpoint and run in debug mode to stop at the exact line of crash.

Clearly you are trying to access objects from an empty array which is bound to crash. It is always advisable to put a check on array size before accessing its elements.
