My two favorite Cocoa books are Aaron Hilegass’ “Cocoa Programming for Mac OS X” (watch for an upcoming 3rd edition) and Anguish/Buck/Yacktman’s “Cocoa Programming”. I reviewed the both on my RubyCocoa site: http://www.rubycocoa.com/book_reviews.

Thanks for letting me know about Nu, and congrats to getting it running on the iPhone simulator!

I’ll definitely have to check it out. The syntax does look a lot like Lisp (which I’ve never used myself — SML is as close as I got to functional programming, and that was a long time ago…), but on your website you claim that Nu is semantically closer to Ruby, so I’m curious.

Oh, and thanks for the RubyCocoa Resources website as well. I have looked at it a few times while searching for RubyCocoa resources. I haven’t had much of a chance to actually play with RubyCocoa yet, though, mainly because I’ve realized that regardless of whether I use Objective-C or Ruby, I would probably first have to invest some time in learning Cocoa itself…

Do you have any recommendations on Cocoa books or other resources that might be most applicable for learning Cocoa for the purpose of programming in Nu or RubyCocoa, without an in-depth study of Objective-C first?

I built the RubyCocoa Resources web site (http://www.rubycocoa.com) and wrote a Ruby to Objective-C bridge from scratch (http://www.rubyobjc.com) but eventually decided that mixing Ruby and Objective-C required too many hacks and that what was needed was a language specifically designed to work with Objective-C.

So as an alternative to RubyCocoa, you might be interested in Nu, the high-level glue language that I wrote as a result of this (http://programming.nu). Yesterday I got it running on the iPhone simulator (http://blog.neontology.com/posts/2008/03/06/NuHelloWorldClassic).
