Amid Privacy Concerns, Apple Has Started Rejecting Apps That Access UDIDs
Amid extra scrutiny from Congress around privacy issues, Apple has started rejecting apps that access UDIDs, or identification numbers that are unique to every iPhone and iPad, this week.
Apple had already given developers a heads-up about the change more than six months ago when it said in some iOS documentation that it was going to deprecate UDIDs. But it looks like Apple is moving ahead of schedule with pressure from lawmakers and the media. It can take more than a year to deprecate features because developers need time to adjust and change their apps. A few weeks ago, some of the bigger mobile-social developers told me that Apple had reached out and warned them to move away from UDIDs.
But this is the first time Apple has issued outright rejections for using UDIDs.
