What do we have:

We have a table view with food items as a list. On selecting a food item, we want to invoke editFood method but only through the delegateAction method.

The Problem:

On tap on any food item, it posts a notification and initiates a series of methods. This results in an exception, our very dear friend EXC_BAD_ACCESS.

Concepts:

Broadly two concepts: debugging and troubleshooting; selectors.

For the former: we want to know the thought process behind debugging a crash, what are the main steps to trace the cause and how would this be different from tackling a SIGBART.

For the latter one: a general discussion on selectors and when could we possibly want to use selector names to invoke methods.
