On page 234, step #4 directs me to "Choose file->getinfo and click the Build tab. Scroll down until you see Enable Objective-C Exceptions, and select the check box next to it". However, I don't see this option as available. I am using XCode 2.3, and my project does not build successfully. When I attempt to build, it highlights the "@throw" line and says "Warning: use -fobjc-exceptions to enable Objective-C exception syntax. What should I do?

Thanks very much.

Presumably the OP found the answer a few months ago :) but just for the record, I just hit the same problem, and discovered one answer: Project menu -> Edit Project Settings brings up a different Info window which does contain the missing option.
