If a UDID is added to an existing provisioning profile, does the IPA require regeneration?

Question

I see a lot of questions that ask how to add a UDID to an existing provisioning profile, but I haven't been able to find any info on whether or not that requires any IPAs using it to be recreated.

So for example if I...

1. Create an ad-hoc provisioning profile "Internal Testers" with just me in it
2. Export an application using that profile and put it up on testflightapp.com
3. Add an additional UDID to my "Internal Testers" provisioning profile

Do I need to re-create the IPA? If the UDIDs end up stored inside the IPA, I'd imagine yes. If the UDIDs are stored online and referenced, I'd imagine no. However, no one seems to have any documentation on which way it works.

Answer 1

yes you do need to recreate the ipa after editing the provisional profile

Answer 2

When using test flight, you can update your provisioning profile, then upload it by hand to test flight build (look under Permissions).

Answer 3

After creating this question, I finally found Publishing to TestFlight, new testers, do I really need to rebuild/download my provisioning profile? which is the information I was looking for. I'm not sure why I couldn't search for this before though. Sorry, all!

z22 did answer the quesiton though so I'll mark him as the official response so no one in the future has to wade through another link.

Answer 4

Yes, When you are using TestFlight Server for sharing your app with others then you need to add his device's UDID in profile. Now suppose if you wanna create an ipa for some other UDID then again you need to add that device UDID and suppose to recreate provisioning certificate again. And then create ipa file doing Archive. From TestFlight, you need to add this new build and create App link.
