What is the Difference Between UDID and UUID?

Recently UDID has captured a lot of media attention as third-party app developers had been sharing this ID with advertising agencies and marketing companies.

On this, Apple has shown its displeasure and sent an ultimatum to all third-party app developers; if the developers shared UDID of iPhones, Mac, or Apple Watch, their apps wouldn’t find a place in App Store.

UDID is a Unique Device Identifier, which is a sequence of 40 hexadecimal characters that provide your iOS device a unique identity. You can find UDID of iPhones, Mac and Apple Watches by using a different method.

UUID stands for Universally Unique Identifier, which is on a per-app basis. UUID recognizes an app on your iDevice, and it will stay there until a user completely deletes the app. If any user removes the app completely from his iOS device and then downloads the app again, the ID will change.
