“A Summary of the WWDC25 Group Lab”

We have a cross platform App available on Mac, iOS & soon tvOS. We are adding a new App Group to be used by this app. We also have a as yet unpublished future Mac Catalyst app that will need access to the App Group. The Apple docs suggest prefixing app groups on Mac with the team ID but not on other platforms. We would like to avoid prefixing with the team ID because: my understanding is that Mac Catalyst apps don't use the team ID and we would like to support that use case to communicate between our current cross platform app and the future catalyst app. Having a single code base but different group container IDs per platform means a bunch of extra conditional logic in the project we would rather avoid. So with that context our aim is to have an app group that is named consistently across platforms and meets sandboxing requirements for App Store distribution. However when developing using the non-team prefixed app group name on macOS Sequioa I see the

An Application Group with Identifier 'group.com.aaa.aaa.onesignal' is not available. Please enter a different string. How can I Fix this error? I need to add it in this format.

Ever since I got my 6S Plus with iOS 9, I've had issues getting texts from group message threads, if the thread includes non iPhone people. Anyone else find a fix for this, or know if the 9.1 Betas addresses this any?

Hi dev forums fellows 🙂I would like to know if the Ratings summary by country provided in iTunesconnect is for ALL versions OR for the Current Version of the app?Apple support told me that ratings summary in itunesconnect was for all versions of the app BUT i have doubts because if i check using itunes PC v.12.6.3.6 then the app page is showing more ratings for ALL versions by country than the ratings summary i see in iTunesconnect for my app!As Apple recently removed the differenciation Current version VS All versions from the web app page, i really need to know which is the good ratings count for all versionsDoes anyone had the same issue and found an ansewer to this ratings question? thanks in advance for your helpN

we have an app in App Store Connect; we have 4 External Testing groups; we have testers, who are simultaneously in two or more groups; tester who consists in several groups can see all available builds in these groups on their device via TestFlight; I choose to remove the tester from one group; check this group - the tester is removed; check other groups - the tester remains in other groups; but checking the TestFlight on the device shows tester removed and NONE of the builds available before can be seen now. According to this article: Removed testers will no longer have access to new builds added to this group in the TestFlight app. They’ll continue to have access to existing builds until they expire, but in fact we can see opposite behavior and the tester looses access to ALL groups and builds in TestFlight after being removed just from one of the groups. So the question is: is there a way to fix this? Or we m

Is there a way to transfer an app goup from one developer account to another?We moved an app and to be able to read the old data on users devices we need access to the old app group, right?Would love is someone could help me out with this, thanks.

We've got an in-house Swift macOS desktop app with a FileProvider extension, which has been working fine on various machines up through Sonoma (and still does). We've just installed it on a Sequoia machine, and on it the FileProvider extension has lost the ability to access the shared app group. It can neither log to the Group Containers folder under ~/Library, nor access the pipe to the main app. The group name is formatted as group.XXXXXXXXXX.com.orgname.appname in both targets. I'm not sure why it combines the iOS and macOS conventions, with both the group prefix and the teamIdentifier one -- it was first built some time before the point in 2025 when macOS supported iOS-style groups -- but again, it's been working. For the record, The provisioning profile for EMPFileProvider has the App Groups capability enabled, and the App Groups capability is present in both build targets in Xcode. The existing group identifier is registered on the

Or did it ever work? I just started trying to get a small setup with a single AU happening. I can play notes and assign midi CC #s to parameters in a plugin, but Command-clicking to open the midi mappings window does only that – I move a midi control as it directs but nothing happens. Notes no longer play and the application is not responding. Clicking cancel in the midi mapping window results in a beachball and I have to force-quit. I've had zero luck with multiple google searches on a variety of terms, so I'm posting here. TIA for any help! I have the latest AU Lab (2.3, created March 6, 2020) on a fresh install of Mojave (10.14.6). BTW - I am assuming, perhaps incorrectly, that midi mapping and host automation are the same thing. Maybe I need to be set straight there. I'm curious though – if Apple means this program to be a test bed for AUs that devs build, how could it not have some way to test host automation? This makes no sense to me.

Hi, Can we hide a subscription group from a specific set of users? For example, I have two types of users saying type A and B. Also, we have two auto-renewable subscriptions belonging to different groups saying Investors Premium and General Premium. Can we hide the subscriptions belonging to the group Investors Premium from general users and subscriptions belonging to the group General Premium from investors?

I have recently restarted an old code base. The app uses App Groups to communicate with network and endpoint system extensions. For some reason, in Xcode > Target > Signing & Capabilities the app groups are showing up with red text. I feel the red signifies a problem, but I cannot figure out what it is. The app compiles and runs, but I feel there is problem that I am missing. Any idea why App Group names would be displayed in red?

I want to transfer a UIImage from the main application to my keyboard extension (in Swift). The only way I can think of to do this is by using app groups. (If there's another I'd love to know 🙂 ) Does anybody know how this would work? Do I need to use Core Data? Thank you!

Hello,I'm trying to automate the creation of app groups for a given bundle id. I've checked the documentation but there are no information regarding what to do to create a new app group identifier and how to connect it to a bundle identifier.I can only enable the APP_GROUPS capability (https://developer.apple.com/documentation/appstoreconnectapi/enable_a_capability) but then there doesn't seem to be a way to assign an app group to a bundle id.The modify capability endpoint (https://developer.apple.com/documentation/appstoreconnectapi/modify_a_capability_configuration) seem promising but there's no documentation regarding the format of the request, and after trying to list the information for a bundle identifier (https://developer.apple.com/documentation/appstoreconnectapi/list_all_capabilities_for_a_bundle_id) with a manually set up bundle identifier with an app group in the developer portal, the API doesn't even return the app groups for a bundle identifier with t

Hi !I set 'ON' in app group setting, and do setting on ADC..And I want to get App Group ID by coding (in the program)Is there any way to get App Group ID by coding ? (do not have to write.. only reading is neccessary)Thanks in advance 🙂

Hello,I can't delete keywords now from the active group (also I can't copy them) and can't delete inactive group — there is simply no button for that.I think that is the really necessary option.Any plans to add it?Thanks.
