I know Apple is quite restrictive about information, but I was a bit surprised to see how far the non-disclosure agreement (NDA) for the iPhone SDK goes: iPhone developers are legally banned from sharing programming tips, discussing code or asking questions of one another in forums or over e-mail!
"F**KING NDA" has become a mantra on Twitter. Every time a developer posts about his or her latest run-in with the metaphorical brick wall that is Apple's NDA, the capitalized expletive is sounded off. "F**KING NDA" has become such a phenomenon, a website has sprung up at F**kingNDA.com to track the twisted tweets.
Apple's software development kit (SDK) for the iPhone is the primary set of tools for building apps for the iPhone, especially if the creations are to be included for sale in the device's App Store. The NDA, which must be agreed to before the SDK can be downloaded, prevents programmers from discussing the finer points of their code.
"There is no legal way for developers to talk about they are developing," Williams laments. "No way to post tutorials. No way to give code away. It's hard to interact with other developers and to write code without reinventing the wheel. Normally, you could post [a coding question] on Twitter and get an answer within minutes."
