TechCrunch notes some of the Apple teams approving apps for the App Store are turning down apps that access the depreciated UDID identifier in iOS:
But this is the first time Apple has issued outright rejections for using UDIDs. “Everyone’s scrambling to get something into place,” said Victor Rubba, chief executive of Fluik, a Canadian developer that makes games like Office Jerk and Plumber Crack. “We’re trying to be proactive and we’ve already moved to an alternative scheme.” Rubba said he isn’t sending any updates until he sees how the situation shakes out in the next few days.
That’s something, because Apple announced the change in August. It is hard to feel for people who are “scrambling” just now.
