Apple is indeed rejecting apps that collect UDIDs without consent, Tapbots has confirmed. The Tweetbot developer says it has received a rejection notice after trying to submit a v2.2 update to the App Store. "We found your app does not obtain user consent before collecting their personal data, as required by the App Store Review Guidelines," the message reads. Apple singles out the use of UDIDs, which are associated with individual iOS devices.
