“A Summary of the WWDC25 Group Lab”

I have an iOS game with one Game Center leaderboard. Recently I published the game and it works fine with no issues. Then I did light version of the game and I'd like to use the same leaderboard for both games. I combined both versions of the game into the Game Center Group and modified leaderboard ID, because Apple requires to start group leaderboard names with grp..Now, if I load scores I receive nil. But if I firstly submit some score and load after that I receive only score for the local player. I checked the leaderboard on itunesconnect and I know for sure that there are a lot of records in the leaderboard. The leaderboard is the same as it was before combining into the group. I thought that Game Center needs some time to update, but I've waited about several days and still see no changing.Do I do something wrong? Or this is just a Game Center bug?I found some similar issues here but with no reply. Does anyone has any ideas? Any help appreciated!

I’m trying to create a layout with a group of labels / tags. The labels have a flexible width and height. If a label exceeds the width of the container it should grow in height. I’m using a UICollectionView with a compositional layout to create this layout. At first I used estimated for the width and height dimension of the layout items within a horizontal group layout that had an fractionalWidth and an estimated height. This worked but only if the cells with the labels were smaller than the group width. If they are larger, the app crashes. Somewhere on StackOverflow I read that this is a known issue. To fix the issue above I made the main group a vertical layout and created a different group for every row of labels. If the labels width exceeds the width of the group I give if a fractional width and if it’s smaller I give it an estimated width. This approach prevents the crashed above and gives me my desired layout. But… as soon as I rotate the device of c

We're seeing a consistent issue where iPads with the A16 chip fail to connect to our BLE device, which uses a Silicon Labs chip running Gecko SDK 3.x. All other Apple devices — including older iPads and iPhones — connect without any problems. According to Silicon Labs, the issue stems from the iPad A16 sending an LL_CHANNEL_REPORTING_IND message (opcode 0x28) during connection establishment: Per Silicon Labs: Currently the iPad 16 will send a message for LL_CHANNEL_REPORTING_IND (opcode 0x28). This is a feature that is not supported in Gecko SDK 3.x. Shortly after, the BLE module responds with an 'Unknown Response' (opcode 0x07), indicating that it does not support opcode 0x28 After this exchange the iPad stops sending meaningful transactions to the BLE module and eventually closes the connection. The BLE Module is responding to this unknown request as specified in the BT Core Spec Volume 6 Part B. Unfortunately, the firmware on these BLE modules cannot be updated remotely, and we'v

We are implementing auto-renewable subscriptions on iOS. We face a problem where users can purchase multiple subscriptions on a single Apple ID linked to the device. We are having 3 subscription plans as Regular (Monthly), Regular (Yearly), and Special (Yearly). Now, we have decided that Regular plans will be configured in a separate subscription group and special plan on the other since we don't want the Regular users to know that there is a special plan that is less costly than theirs. (Through Manage Subscription of the device Settings) Scenario 1: If User A subscribes to the Special plan on his Apple Id, his subscription gets active. Now, if on the same Apple ID, user B logs in to the app and is a Regular user then he can purchase any of the Regular plans. But the issue is User A's receipt and User B's receipt cause problems sometime later since their receipts are created on the same Apple ID. We are not able to restrict User B to purchase from User A's device in this case, since the original_tra

I get the distinct feeling, based on the WWDC presentations, that group iMessage apps are either incomplete or not really thought out. Add to this that there are no group conversations possible in the simulator. The group message part of the demo was just a couple of slides and he used the phrase we are recommending for the moment which leads me to believe that Apple probably has unfinished business here. I think that the idea of making MSSession the carrier of data and make each subsequent message create a stack of unprocessed responses so that when the user clicks on the bubble it sees each response and can process them one by one. What I'm wondering is, in the same section, they talk about privacy. So each device will get different identifiers for each user. If you are using the cloud, I don't see how you can then aggregate responses correctly. Take this scenario:I send an iMessage App (IMA) to two of my friends and it asks them to pick what they want for lunch.Friend A responds

I know that Apple is very aware of privacy concerns. Do Share Play and Group Activities comply with GDPR's legal rules? What kind of servers (e.g. geography) are involved to manage the connection? Thanks Lars

Hello, I am trying to use app groups to share preferences between an app and its QuickLook extension (both sandboxed), but I can't understand why it's not working. For testing, I created an empty macOS app project and added a QuickLook Extension, then on both the targets' entitlement files I added the app group domain in the form teamid.test. Last but not least, in the Info.plist file of the QL extension i added some UTIs to have the QL extension called when previewing. In the QL extension's PreviewViewController.swift file I try to save a value like this: func preparePreviewOfFile(at url: URL, completionHandler handler: @escaping (Error?) -> Void) { let defaults=UserDefaults(suiteName: teamid.***) defaults?.set(1, forKey: test) handler(nil) } If I try to run the app and preview a file though, I get this message in the Console: Couldn't write values for keys ( test ) in CFPrefsPlistSource<0x7fb63681cce0> (Domain: teamid.***, User: kCFPreferencesCurrentUser, ByHost: No, Container: (n

Howdy. I recently discussed the tab feature from within Google Chrome. I absolutely love this feature. This is a long shot, but is there any way to create similar tab groups with the available window icons on mac OS?

Are there current plans to implement Microsoft 365 groups with Platform SSO to control administrator access in macOS 27? If so, would you be able to provide a rough estimate of when we can expect changes to be implemented by identity providers?

All identifiers updated in summer 2020 has new value for keychain-access-groups - com.apple.token. What is its purpose? What can happen if this value will not be added to entitlements?

Hi,We can add app-group to Containig application and app-extension to share the data. But is it also possible to add app-group to iOS plugin's entitlements so that it can also have an access to shared container if needed?Thanks and regards,Sanjay

Any chance to be scheduled?

I am adding Group Activities integration with a MacCatalyst app. I have added the Group Activities entitlement in Xcode. I also checked the entitlements with : codesign --display --entitlements :- I can see the entitlement : com.apple.developer.group-session The feature work fine on iPadOS but when I run it on MacOS, the GroupActivitySharingController is not loading properly. I get the following error messages: Cannot run query EXQuery: extension point com.apple.groupactivities platforms: 6 with error: (null) Failed to lookup extension with query EXQuery: extension point com.apple.groupactivities platforms: 6 on <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to fetch config for hostViewController <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to build remote hostViewController for <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250> Failed to fetch extensionViewController Calling -viewDidAppear: directly on a v
