My main issue is how to know exactly when to declare instance variables weak
or strong. There seem to be some subtleties in that area that I don't yet
understand. On the other hand, it appears that these issues will rarely be
encountered, and that the simple rules of thumb in the documentation will
almost always be enough.

I've never used Ruby, so I can't answer your question. The question I would
ask is the other way around: what kind of headaches would I have jumping
into Ruby?

After programming for years in Pascal, plus Basic before that, I found
learning C pretty easy. Then when I got into Objective-C and the Cocoa
frameworks, it took me an hour or two to understand the Objective-C
additions to standard C and maybe a day to be able to use them comfortably.
The Cocoa frameworks take a lot more study, of course, but that has nothing
to do with the language -- it's just like learning any new framework.
