I have an app published on the AppStore and I want to migrate it to an enterprise developer account for in-house distribution. I read in the enterprise documentation that:
If you want users to keep the app’s data stored on their device, make sure the new version uses the same bundle-identifier as the one it’s replacing, and tell users not to delete their old version before installing the new one. The new version will replace the old one and keep data stored on the device, if the bundle-identifiers match.
Now, assuming we keep the Bundle ID the same between the AppStore binary already installed and the enterprise binary signed with a different certificate... it should overwrite the same app on their phone rather than create a second app.
I contacted Apple support and they said "No, you will have 2 apps installed if you do not instruct the clients to uninstall their old one". Is this true?
EDIT: I'm leaving my original answer below for conversations sake as there is good dialogue below. As #mja noted when you initially create an app ID it is associated with one of a few available prefixes to your developer portal and that prefix may be used by iOS to associate & differentiate between apps.
EDIT2: When I go into my Enterprise Portal and try to create an app ID with an identical value to an existing app ID but with a different prefix it still blows up on me and says:
An App ID with Identifier 'com.mycompany.myapp' is not available.
Please enter a different string.
ORIGINAL Answer:
The latter part is incorrect - iOS devices use the Bundle Identifier to differentiate between apps. I can have 20 apps labeled "Cool App" on the same iOS device so long as they have unique bundle identifiers such as com.mycompany.coolapp.1 - com.mycompany.coolapp.20. Likewise (and I've done this accidentally) if I open two projects, both of which have bundle identifiers com.mycompany.myapp, and run one right after the other the last app to be run will be installed on the device whereas the previous app will be overwritten.
Regarding the app data sustaining itself I have not tested that though I'd be interested in what happens for you!
I have managed to achieve this, so that the 'enterprise' build of the app overwrites an 'app store' distributed version.
This does not use the exact same bundle ID but does achieve what OP asked in his original question.
How I did this was, in my enterprise account, create a wildcard bundle identifier with the first two parts the same as the bundle identifier for our production app, for example:
Production : com.xyz.abc
Enterprise : com.xyz.*
Using this wildcard bundle ID, the app can be distributed and will overwrite any versions installed via the app store (user data will still persist). The prefix does not seem to matter here.
One drawback of the wildcard bundle id is the fact that you cannot use APNS etc.

I read from Cocoa Core Competencies
that
An App ID is a two-part string used to identify one or more apps from
a single development team. The string consists of a Team ID and a
bundle ID search string, with a period (.) separating the two parts.
However it also says that,
The bundle ID is a unique identifier that identifies a single app and
cannot be used by other teams.
I see that we can't register an App ID in the Developer account portal with same bundle ID of an app that is on the appstore.
An App ID with Identifier 'com.example.myapp' is not available. Please enter a different string.
So I don't know if 2 apps from 2 developers can have same bundle ID (like com.example.MyApp), and if this causes any conflicts?
Can these 2 apps be installed on the device?
Can these 2 apps be allowed on the app store?
How does Push Notification work with these 2 apps ?
I see that many services like Fabric Crashlytics, Urban Airship, Google App Invites, ... depends on the Bundle ID to differentiate among apps.
Can these 2 apps be installed on the device?
No, it won't. It will replace the existing app.
Can these 2 apps be allowed on the app store?
No, you cannot create Apps on App Store with same bundle ID.
How does Push Notification work with these 2 apps ?
Push Notifications will show for the app it is made for whose Push Certificates etc are made
Can these 2 apps be installed on the device?
No. If you tried to install another application with same bundle ID it will replace the existing one.
Can these 2 apps be allowed on the app store?
No. When you upload the application on an App store it will ask for unique bundle ID.
If you use same bundle identifier for two different application and try to run on device then previous application is replaced from Device and current application is installed on Device. if you want to run two different application then you can use wild card id.
for App store when you creating application in iTunes connect first it check with existing App ID(same with bundle identifier in Xcode) on app store if exits the you have to put different app id.
I'm stuck in a slightly weird situation. When our app was first created, nobody really knew what they were doing and I'm trying to clean things up a bit.
In the iOS developer center, it seems that there are two App IDs for my app. I think I can delete one of them, because the other one is the one that is actually being used, but I'm not 100% sure.
Here is the App ID that I think is actually being used in our released app:
Here is the "other App ID":
The annoying thing is that the "other App ID" seems to match the bundle ID of the app and xCode seems to be trying to use it as the application-identifier when the app is submitted to the store. I don't want the application identifier to change.
Is it safe to delete the other app id? Can I force xCode to use the correct application identifier? How can I tell which app ID is actually being used by our released app?
Edit:
Why this arose is because after submitting our latest build to the store for testflight, I got this notification:
Dear developer,
We have discovered one or more issues with your recent delivery for
"My Cool App". Your delivery was successful, but you may wish to
correct the following issues in your next delivery:
Potential Loss of Keychain Access - The previous version of software
has an application-identifier value of ['ABCDE.MyCoolApp'] and the new
version of software being submitted has an application-identifier of
['QWERTY.MyCoolApp']. This will result in a loss of keychain access.
After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.
Regards, The App Store team
The fact that the application-identifier is changing, and that it appears to be using the "prefix" as part of this value, suggests that it was using the first app ID, but now it is going to use the second.
Do you have access to login in to the iTunes Connect for that account? That's what you really need to verify the bundle ID (aka app ID) of the released app.
Login at itunesconnect.apple.com, click on apps, click on your specific app, click on the 'more' tab, click on 'about this app' it will show you the bundle ID being used for the released app. Feel free to delete the OTHER app ID out of your account. Not the one in iTunes Connect :)
The bundle ID in your Xcode project can always be modified to match whatever app ID you'd like, as well as you can easily regenerate any necessary provisioning profiles for any app ID. (of course, you should make it match the existing one in iTunesConnect if you want to release an update for that app)
Edit:
It sounds like you've been able to match up the app ID, but not the prefix. The way prefixes are assigned has changed over the years and now they are all team based. You can read this technical note and see if it will help you resolve the warning you encountered.
Developer Link
The primary difference between your 2 App ID is the ID:
the first one has '*' as ID. It means it is a wildcard ID. You can create multiple applications using different bundle identifiers with the same provisioning profile using this ID. But you don't have access to specific capabilities such as Push Notifications, in-app purchase (because multiple apps will share the same profile
the second one is fully qualified and can be used only with the app whose bundle identifier is 'MyCoolApp' and can have access to full capabilities of apps.
Note that your app ID naming convention should be in reverse url format as Apple advices: myCompany.myInternalGroup.myAppId.appFlavor for instance.
I am trying to understand the role of the first part of the AppID for iOS apps.
This part was formerly known as the "Bundle Seed ID", but is now often referred to as the AppID Prefix.
A while ago (iOS 5?), Apple made some changes in both their portal and their documentation and started to recommend using the "Team ID" (unique per developer account) as the AppID Prefix. This is simple and straightforward for new developers with new apps.
But what is the the best practice for handling existing apps with regards to the AppID prefix?
I know that it is not possible to change BundleID (= the second part of the AppID) between two app versions, but is it safe to change the prefix between app versions?
Note that I am not referring to replacing a "wildcard AppID", e.g. ABC1234567.*, to an explicit AppID using the same prefix, e.g. ABC1234567.com.mycompany.myapp. There is tons of information about this (most of it outdated, though). I am thinking about changing the complete AppID, e.g. ABC1234567.com.mycompany.myapp, for an existing app by replacing the prefix with my Team ID, e.g. DEF7654321.com.mycompany.myapp.
I think I have read somewhere that it should be OK to change the prefix for existing apps, except in the special case that the app is using the keychain to store data. If this is true, the easiest way to handle the prefix for existing apps would be to migrate to the new Team ID when it's time to release next update. When all my apps are migrated, I can continue using the Team ID (as Apple recommends for new apps) and finally forget about all this mess.
Can anyone confirm this?
If you can shed some more lights upon the concept of the AppID prefix, and what it is actually used for on an iOS device (except the keychain which I already know about), I would be happy if you could write a comment. Perhaps we could build up the full understanding of this by adding bits and pieces from different sources. Sadly, the Apple documentation is very thin in this area.
(There is another similar question: Can I change the Bundle Identifier in my app after it's been approved? But that is mainly focusing on the BundleID, i.e. the second part of the AppID, so this is not a duplicate, even though some of the answers and comments are touching upon this topic.)
My conclusion, as of today, is that it is completely safe to replace the AppID prefix by a new one, with the exception of apps using the keychain. This opens up for migrating the prefix for all my exiting apps on the App Store to the new TeamID based prefix.
This conclusion is based on the following input:
A discussion I had with Apple's developer support a couple of weeks
ago. They told me that there should not be any problems changing the prefix, except for apps using the keychain.
A test I did, using ad-hoc distribution, verifying that an existing app on a test device did not lose any data when it was updated to a new version with another prefix.
The fact that I have successfully uploaded new versions, with replaced prefix, of two
of my existing apps without any problems so far.
The status of the two "live" apps that I have changed, is that they have been approved in the review. However, they are currently waiting in "Pending Developer Release", since I am waiting for a third app to get ready in order to sync the release with that one.
If I see any kind of problems when they go live on the App Store, I will of course update this answer.
Update:
The two apps were released successfully more than three weeks ago. The roll-out worked as expected and I have not received any user complaints.
In summary, the answer is YES, this is completely safe!
Apple published a new tech note on February 12th 2014 confirming that it's possible (and safe*) to change Prefixes yourself for Wildcard App IDs, but it's still impossible to do it yourself for Explicit App IDs.
However, they say you can contact member center maintainers if you would like them to change your Prefixes for Explicit App IDs.
Gonna include this part here in case they change their mind again:
All other App IDs will require the assistance of the member center maintainers - if you are not using a wildcard App ID, then you should contact the iOS member center maintainers for assistance. Here are the steps you can use to do that:
Go to https://developer.apple.com/contact/.
Submit a request by clicking the link under Enrollment and Account.
* Keep in mind that if your app stores data in Keychain, changing app ID prefix will result in one-time Keychain data loss.
A few quick questions on App ID's / Submission if you don't mind,
1: Can many App ID's can be added to the same provisioning/distribution profile? - so apps with different app ids can be distributed to the store with the same distribution profile?
2: Can you release an app to the store with a wildcard app id?
3: Does enabling services on an app id just allow you to use for example iCloud apis? If they weren't enabled would iCloud Apis (for example) just be ignored in the app?
4: When I was submitting my app last night, iTunes Connect needed a bundle id, which I set to say "com.John.myApp" -- when I was validating my app it said that my Apps bundle Id in xcode had to match "com.John.myApp" that I set in iTunes connect....
However in xcode my bundle id was something bigger like: "com.John.${PRODUCT_NAME:rfc1034identifier}"
so I just set it to "com.John.myApp" is that ok?
Thanks all,
Use a wildcard profile.
Yes.
It depends on the service, and some services won't work with a wildcard profile.
Yes. The default you replaced is just a default, a lot of people will have the app name in the bundle I'd but you don't have to.
I have been excited to try to add for the FIRST time a new App on iTunes Connect to TEST my GAMEKIT features.
I have read this technical note and I am getting confused because I had already a boundle id for my App that I created when I started developing it (that's my current bundle id with which I created the current provisioning and testing profiles: hello-*).
In order to use GameKit and InApp Purchase should I create a new Bundle Id?
I am confused because:
I don't know if the current Bundle Id is valid (in respect to the technical note linked above)
I don't know if hte Bundle Id influences the things that I can ADD in the App later (E.g. in App Purchase, GameKit, ...)
If I create a new App with a name (say: HelloApple) but with a bundle Id with wildcard (Say: hello-*) will I be able to add a new App with the same name but a different bundle Id in a later stage? This indeed before publishing ANY of the two Apps.
I don't fully understand why there is a choice between using or not using a wildcard; in other words, if a non wildcard bundle id is needed to use in App purchase and GameKit why should a developer want to use a wildcard App Id?
Any help will be appreciated, in particular I need to solve my first issue: which bundle Id should I use in ordert to use GameKit and InAppPurchase?
Before answering your questions some definitions:
Bundle ID: A reverse DNS string that precisely identifies a single app.
Bundle ID search string: it is used to match a set of bundle IDs, where each bundle ID identifies a single app. For example, if the bundle ID search string is com.mycompany.MyApp or a wildcard such as com.mycompany.*, then it will match the bundle ID com.mycompany.MyApp.
App ID: A string that identifies one or more apps from a single team. An App ID consists of a bundle ID search string preceded by the Team ID, a 10-character string generated by Apple to uniquely identify a team. In the technical note that you link it is ABCDE12345 and called the Bundle Seed ID.
(Development) Provisioning Profile: you use it to authorize your app to launch on devices and use certain store technologies when you are in development. It is comprised of: a single App ID, a set of devices, and a set of development certificates. The provisioning profiles are created in Member Center and you need them on your device to run your app. XCode can download provisioning profiles and install them onto devices.
Now I will answer to your bullets:
To use Game-Center (GameKit) and IAP you need an explicit App ID, that is and App ID with a bundle ID search string that has no *. A wild-card App ID is one in which the bundle ID search string that has a *, and is the one you have now.
What you create initially is an App ID with an associated Bundle ID. If it is explicit you can add Game-Center and IAP, if it is a wildcard App ID not... that's it.
You can not have two apps with different names but the same explicit App ID or Bundle ID. But you can have two apps with different names that do not use Game-Center or IAP with a unique App ID using a wildcard App ID.
You ask why the wildcard is useful... Well, I said that if you do not use Game-Center or IAP you can have two or more apps associated to an wildcard App ID. Then you can create a provisioning profile with this App ID and you only need to install this provisioning profile on your devices for all your apps. There is a default provisioning profile of this type called the Team Provisioning Profile which is valid for all your apps, but you could create more specific ones that are valid for a subset of all you apps.
This process is really useful for big teams. If you have a small team and few apps it is really confusing, but it helps to understand the reasoning behind it.
But there is more to say about all this. I recommend that you read the "App Distribution Guide" as I did recently. It is an extensive guide, but for the moment you only need to read sections of topic "Maintaining Your Signing Identities and Certificates" and "Maintaining Identifiers, Devices, and Profiles". The guide is very clear, full of screenshots and it will answer all your questions. Also you can go back to the guide down the road to quickly solve some issue (and you will have issues).
The first time that I created an App with Game-Center and IAP more than a year ago I looked up stackoverflow to answer all my questions. But I've been having issues when certificates expired, when I added new devices, etc, and every time I found and Ad-hoc solution after a lot of fiddling around and going back to stackoverflow. Don't get me wrong, there are great answers in stackoverflow but it is a much better strategy in my experience to read something longer that explains the big picture. App ID, Bundle ID's, Certificates, private keys, etc, is a messy subject, specially if you do not understand why it is built this way.
The bundle id is just an identifier for your app. It's mainly used to provide you with the certificates you need to use to sign your app before submitting to the App Store or to use it on development devices (e.g. for testing). The bundle id can be whatever you want. Apple recommends using the syntax com.yourcompany.yourapp to keep it consistent among apps you develop and avoid conflicts with other app's identifiers.
A wildcard can be used on all your apps, while a specific id can be used with one app only. I advice you to have an id for each of your app and only a wildcard for development (so you can run on your devices as many apps as you want without having to bother about the certificates until you decide to ship the app). You don't need to have access to all services (like Game Center or iCloud) on all your apps and therefore you better sign the single certificates just with the services your app needs.
What I think Apple wants is:
Create a different bundle ID for each app that uses in-App purchase/GameKit or both.
You can have same App-ID, and bundle ID for apps that do not use these.
If the bundleID you have for your app is not used for any other of your apps, you can use it.
Somebody more knowledgable, Please correct me if I am wrong.
