It's just a learning curve I guess.

Yep. Cocoa has a fierce one, but it also lets you make some fine apps.

It just reminds me of how things used to be about 12 years ago when I last did any C or C++. I've been doing nothing but Java since that point and have forgotten all about the need to consider memory management.

I know what you mean. I do Java more often than Cocoa, and I find automatic memory management a godsend. Frankly, the VM is usually better than I am about collecting when needed for the most common cases. (Java still falls down big time for small but limited objects like file handles.)


Accessorizer from Kevin Callahan, will handle most of the grunt work of memory management for your instance variables, which helps bunches.

I have also gotten very used to how easy it is to pull data from just about any database from Java. Perhaps some day Core Data will be able to do much the same for MySql and Oracle, and I will be better able to write more of my apps in Cocoa. Core Data is quite keen, for the domain they have targeted, and I still find IB beats every Java gui builder I have tried.
