The iOS developers who are trying to make their Apps enter into the iOS App Store are now complaining about the App getting rejected by Apple as it accesses the Unique Device Identifier (UDID). Last August when Apple had launched the iOS 5 had announced that the UDID would be deprecated and would eventually be phased out. Apple has now bought that term into effect and now iOS developers who need to make their App enter into the iOS App Store need to create Apps which would not require accessing UDID.
UDID is a unique string of Alpha Numeric characters which is unique for every device. It is used for various activities like mobile ad networks, game networks, analytic’s providers, developers and app testing systems
The UDID issue had originally came up as it helps Apple and several iOS Developers to track users across different apps. The privacy issues concerning the tracking of user withe the help of UDID has risen to significant standards.
From TechCrunch :
Two of the 10 review teams started doing blanket rejections of apps that access UDIDs this week. Next week, that will rise to four the ten teams, and keep escalating until all 10 teams are turning down apps that are still using UDIDs.
The iOS App Store is already a very tightly guarded walled garden of Apple environment. This extra measure will make it even more secure and most importantly much more beneficial for iPhone and iPad users.
