“A Summary of the WWDC26 Group Lab”

I am working on two applications that provide complementary functionality - one is a main app with authentication flow and the other handles additional functionalities within my service. I would like to publish these as separate apps on the App Store but allow them to share data through an App Group, specifically to enable sign-in state to carry across. The flow would be: Main app authenticates the user and saves an authentication token to the shared App Group container Second app launches and checks the container for this token. If present, it signs the user in automatically. In this way the Main app handles all login functionality which enables certain features in the other app(s) when logged in state is present. My questions are: Would this violate any App Store guidelines around app functionality distribution or data sharing? I intend to provide a technical rationale during review on why two apps are necessary. Would Apple allow such an implementation? What best practices should I follow

Does the ability to create groups for external testflight users no longer exisit? I was able to do in last week, but it does not exist this week.

I just seen a discussion that had to do with App Groups. What’s the difference between App Groups and iCloud? Thanks, Dan Uff

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.

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 We also have a as yet unpublished future Mac Catalyst app that will need access to the App Group.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

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'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

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?

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.

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?

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
