The Big Nerd Ranch has conducted iPhone development courses all the way back to the very beginning, when the App Store first launched in 2008. Doing so had its challenges.
At that time, Apple had imposed a nondisclosure agreement on all developers, with little indication if and when it would ever be lifted.
Under the terms of this agreement, developers could not discuss details of the OS and the SDK -- a limitation that challenged any business based on development training.
BNR CEO Aaron Hillegass devised an insane, brilliant, and counter-intuitive solution. Leveraging a little known clause in the agreement, he conceived a way to make an end-run around the letter of the law while still holding classes.
