“A Summary of the WWDC26 Group Lab”

I have an app with 2 app extensions. I have set all 3 of them up as an App Group. Each of them have a separate app and bundle ID. Now, when I submit the app on iTC, do I submit 3 apps; i.e.build each target separately, generating 3 .ipa files and then bundle them up on iTC? Or is it OK to compile everything(all 3 targets) in 1 bundle and just submit 1 .ipa file?

We have identified Subscription Groups for our use-case based on the below note from Apple, but there is no mention of any limitations in the doc. Can we create unlimited number of Subscription Groups or is there a limit? If your app needs to offer users the ability to buy multiple subscriptions — for example, to subscribe to more than one channel in a streaming app — you can add these subscriptions to different groups. Users who buy subscriptions in multiple groups will be billed separately for each subscription. Thanks in advance!

These questions are community-driven. I am also not the original questioner, I'm just posting them with permission. Thank you to the anonymous folks who helped gather this information.DEP / deployment / general related:- ASR restore on AFPS: it will be a Thing of some sort. The engineer spoken to hinted that they didn't even know internally exactly how it would work yet, but they fully expect to support asr restores in the future, even with APFS.- System Image Utility: the team that writes it knows it is broken, and wants it to be fixed, and expect to have it resolved with APFS support, but maybe not until seed 3 at the earliest- APFS on the Mac in general: they know it's still kinda broken. Not a single person I talked to sounded confident about using it for anything _right now_ and that it will likely take multiple seed iterations until it's in the state they feel like it should be. NOTE: This is my interpretation of the subtext of what they were saying. No one flat out stated that.- NetBoot / NetInstall su

Hey,I have an existing iOS App with Game Center Leaderboards and Achievements that I now want to transfer to a Game Center Group for multi-platform shared leaderboards. (OS X / tvOS)1. I have an update already in the review pipeline set to the standard leaderboard id's.2. I have setup a Game Center Group for this App post this being in review.3. I want to retain all player scores / achievementsNotes: According to Diego:I migrated to my game to GC groups, then submitted my game for OS X using the grp prefix. I didn't have to make any changes to the iOS version, it just worked. Game is called Arcane Tower in case you're interestedI checked his App on iOS and OS X and the leaderboards are in sync.So it seems the old id's (original ones) seem to keep in sync with the new grp versions. However if you create a new application using these you must use the grp prefix to address them (say the OS X version or tvOS).My questions are:1. Do I need to modify the iOS leaderboard / achievement id's

We're in the process of moving our app's storage from the app container to an app group container so that the data can be accessed by app extensions (such as share extensions) as well. However, we found that Xcode does not backup app group containers via the Devices and Simulators window. How can I include the app group in the backup and restore process? Similarly, could you confirm that app groups are indeed included in the iCloud backup and restore process?

Hi folks, I'm trying to build communication between the main app and its helper via inter-process communication. I found here that it is possible if the apps are in the same app group. But I really cannot make it work, and cannot understand what I do wrong. It works all good if I add com.apple.security.temporary-exception.mach-lookup.global-name entitlement, so the setup seems to be correct? Where should I look to fix it? Also because having that entitlement means that it is gonna be tricky to get through the App Review.

Hi,Using iOS CallkIt VoIP API on iOS 10.THe API for CXSetGroupCallAction allows specifying a call UUID and another UUID of a call to be grouped with.THis suggests only two calls are allowed in a group. Is this the case or are more calls allowed in a group ie 3+.Thanks

Hello everyone, I am trying to save an identity into a group keychain. I am doing it this way, following the documentation: let queryAdd: [String: AnyObject] = [ kSecClass as String: kSecClassGenericPassword, kSecAttrAccount as String: kSecImportItemIdentity as AnyObject, kSecValueData as String: identity as SecIdentity, kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked, kSecAttrAccessGroup as String: accessGroup as AnyObject ] let resultCode = SecItemAdd(queryAdd as CFDictionary, nil) if resultCode != noErr { print(Error saving to Keychain: (resultCode)) } I am getting error (or resultCode) -50, which means password has not been save successfully. As a no-team programmer, my accessGroup it's just the group Bundle identifier, registered in Signing & Capabilities -> Keychain Sharing. I don't know if maybe the reason of this code is because the group is not alright or something else it's happening, although it looks I am using the identity the right way.

Is it possible to change the Primary App ID set in the Group with an existing primary App ID to another Primary App ID within the same group If there is a change, whether the sub values of the token will be changed upon successful login If an app corresponding to the existing Group Primary App ID is deleted from the app store, ask whether or not other apps in the same group are affected and what effect it will have If anyone knows about the above, please let me know please

Recently my app was rejected because I have accidentally included two subscription groups that I did not intend to sell. In the current App Store Connect UI, I don't see a way to remove the subscription groups from this version, or entirely from the account. These items have never been on sale. Does anyone know how to fix this issue?

Hello, I have a question about subscription groups in in-app purchases. Suppose I create a subscription group like this: Subscription Group A Subscription Item A1 (one month) Subscription Item A2 (one week) Subscription Item A3 (one year) The documentation mentions, A subscription group is made up of subscriptions with different access levels, prices, and durations so people can select the option that best fits their needs. Since people can only buy one subscription within a group at a time. Does this mean that if a user purchases Subscription Item A1 in Subscription Group A, they can only purchase other subscription items in Subscription Group A after the one-month period ends, when that subscription expires?
