What less-than-serious attempts have you made at less-than-real
Cocoa programs? Were all those attempts successful, i.e. did they
result in a working program for whatever less-than-real task they
were supposed to perform?
One person's idea of "serious" or "real" can be very different from
another person's. You haven't described your experience level in
making working Cocoa programs, so it's difficult to advise whether
Core Data is beyond your skills or not.
You also haven't described your tolerance for risk or outright
failure.
Suppose you create a Core Data model, and spend weeks or months
trying to get the app working, but are not successful. At what
point would you be willing to say that you're in over your head and
should stop trying to use Core Data? In other words, when would you
admit defeat and do something else?
Some risk-tolerance will depend on why you're writing the lens app
in the first place, and what deadlines there are, if any. If it's
for your own learning and/or amusement, then maybe you should try
Core Data, after reading the prerequisite docs first. The primary
goal is learning, even if the app never works. However, if it's for
a product that has to ship on someone else's schedule, maybe you
shouldn't use Core Data right away, but get your basic design
working first and then re-evaluate if necessary. You may find that
using other mechanisms gives you what you need, as well as a basis
for possible future use of Core Data.
