A variable shouldn't be nil. Say it's nil. How do I break the program when it's nil?

Debug assert? Objective c?

C assertions should work.

Also look up NSAssert.

FWIW, google search terms: ios assert site:developer.apple.com

And see this:

I don't believe that the issue mentioned in the "NSAssert considered harmful" blog post applies on iOS. It does, kind of, on MacOS X.

I use NSAssert in both Mac and iOS code and it works as expected. I believe this is what OP should use.
