So as you all are panicking to get your UDID-replacing code submitted before May 1st Doomsday, might want to check out

The Developer’s Guide to Unique Identifiers

We had been warned that uniqueIdentifier was going away, and now Apple is giving us not just one but two alternatives to use. But which one should you use and when is it appropriate to choose one over the other? The documentation doesn’t answer these questions and it is left up to you to decide what is best for your applications’ purposes.

I am going to outline each of the iOS supported and deprecated unique identifier methods to explain what they do in hopes of arming you with the knowledge you need to make the right decisions…

Just in case there’s anything there that you might have overlooked so far.

Now, that article does omit the SecureUDID solution that we thought looked pretty nifty last April, so if you’re not going forward with IDFA/IDFV only, might want to give that one a look over as well.
