Different vendor IDs in multiple apps from same vendor

Hello -

We recently launced a second app in the app store. We're doing some work to find users of both our apps via a common Vendor ID. However, after installing both apps from the App Store, I'm getting 2 different vendor IDs.

I've tested with iOS 7.1.1 and 8.3

I've read this https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIDevice_Class/#//apple_ref/occ/instp/UIDevice/identifierForVendor

From that documentation, it would seem I should be getting back identical vendor IDs.

Our bundle IDs for our apps are completely different. App 1: com.x App 2: me.y

What can we do to ensure users of our second app will have the same vendor ID if they have our first app installed on their device? Do we need to change our bundle id on our second app? And if so, what are the ramifications of that (submitting a "new" app, re-generating certificates, profiles, etc)?

Any insight would be greatly appreciated!

Hi,

we are experiencing in a way similar problem with vendor IDs.

With our latest app update released yesterday all or some of our clients vendor IDs changed.

Could it be possibly related to merging the iOS and mac dev programs?

Any insight would be greatly appreciated!

We have one live App on Apple store and in that we have a call for identifierForVendor from iOS which is used as one of evidences in KPS call. This value is supposed to be same for the apps that comes from the same vendor running on the same device. We are seeing in the log that this value is getting changed. This is not supposed to change on app update for the same vendor.

We have recently migrated the app from one apple account to another but everytime we are trying to fetch the value it is not constant.

We refererred to the following link for more details:

https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIDevice_Class/index.html#//apple_ref/occ/instp/UIDevice/identifierForVendor

But the link doesnot have sufficient information to help us with the issue.

The problem is seen only in version updated to the new Apple account. Can you please put more insight on the same as only the team id is changed moving the app from one account to another and let us know what could be possible issue or fix for the same.

Any insight would be greatly appreciated!

This has been reported by many people and it appears to be a problem on the Apple side. If you search this forum and the archived forum for "identifierForVendor" you'll see lots of discussion on it.

You should probably file a bug report to add to the pile.

IDFV does change while migrating developer accounts!

We encounted the same problem, IDFV was changed on several million devices which caused a huge mess to us.

Hi,

We have faced same issue, but today, it seems to be fixed.

Could you check it out? and do you have any bug fix info especially about AppStore??

(I didn't modify application code.)

previous situation(issue)

BundleID: different (com.x.y, me.a.b)
TeamID: same
IDFV(IdentifierForVendor): different

today

BundleID: different (com.x.y, me.a.b)
TeamID: same
IDFV(IdentifierForVendor): same
How to fix: uninstall both application completely, then re-install both application.
notes: I didn't change/fix application.

Thx.
