“A Summary of the WWDC25 Group Lab”

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, 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?

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?

In iOS 16 beta 3, my iOS app sets some strings in the shared user defaults of the app group. The iOS widget extension reads the strings from the shared user defaults correctly, but the watchOS app and watchOS widget extension could not read them (get nil). Integers stored in the shared user defaults can be read everywhere. All targets are in the same app group. Does anyone have similar problems?

If I search for regex (.*)How do I replace with the capture group? It was 0 and then $0. Any clue what it is in the new editor?For bonus points: can I change the case on the capture groups?Thanks,Andrew
