The O in iOS is for Orchestra (CIDUG meeting, July 27, 2010)
Geoffrey Goetz gave a presentation on iPhone application development at the Columbus iPhone Developer User Group on July 27, 2010. His topic was mainly a recap of some of the application approval and performance issues that were covered at the 2010 WWDC.
The most interesting part of his presentation for me was his presentation on using the Zombies feature of Instruments. We had some random crashes going on in our Basketball Statware application, and this might have helped to chase down the problem. As it was, I believe we fixed the problem by moving like named variables just sitting by themselves in the implementation files inside the class as class variables.
