Thread-topic: Guidance for Cocoa's steep learning curve

Exactly. Deferred-release makes reference counting easier. Looser more
dynamic typing makes certain things more convenient & more concise.
Delegation keeps the single-inheritance hierarchy shallow and
comprehensible. The handful of powerful patterns are used consistently and
to very good effect in the overall design. There's no one thing shockingly
different; just a few good ideas applied effectively and consistently. (And,
I should add, with a tolerably lightweight runtime cost for the dynamic
bits.)
Learning the basics of Objective-C & Cocoa was dead easy. Starting to see
the way it all fit together took longer. Getting a grip on the breadth of
the whole framework, or the depth of how to modify behavior of standard
classes--that takes a long time.
