“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

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?

I've implemented Communication Notifications in my messaging application but am having difficulty with figuring out why notifications aren't being grouped by conversation - instead, they all collapse into a single group. I've verified that the conversationIdentifier of the INSendMessageIntent is being correctly set for my notifications, along with the speakableGroupName. Is there anything else I could be missing to achieve the desired conversation grouping behaviour?

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?

I need to put a file inside a group in xcode, but every time I try, it throws an error. This is what I did: I selected the file that I want -> New group from selection. When I name the group and hit enter, I get the following error: `An unknown error occurred. Domain: com.apple.dt.SourceControlErrorDomain Code: -1 Recovery Suggestion: failed to read index: '/Users/Path_to_project/.git/index' no longer exists (-1) User Info: { DVTErrorCreationDateKey = 2022-11-30 18:32:36 +0000; com.apple.dt.sourcecontrol.UnderlyingErrorString = failed to read index: '/Users/path_to_project/.git/index' no longer exists (-1); }` The file, let's call it helper.swift is in the same level as projectNameApp.swift. It was working fine until a coupe of days ago. Out of nowhere xcode started throwing a permission related error for helper.swift. The error goes like this -> The file “Helper.swift” couldn’t be opened because you don’t have permission to view it. I have both read and write permission for t

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?

I want to ask a question about App Transfer. We have succesfully transferred our iOS app to new developer account. App ID and bundle is transferred but there is no app group id and push notification certificate in new developer account.Our database is stored in the app group container and have to create same app group id in new developer account. I want to ask you if there is any risk to delete old app group id from old account and re-create the same app group id in new developer account. Will any App Store users affect data lose or etc ?Or, is there any other way to transfer App Group ID to new developer account ?Thanks

Hi, I'm developing an app with a functionality to invite and add members to a group (the back-end work is already done, but I'm looking for better front-end). For this functionality, I need the ability to... Show current members (after they have accepted the invite). The ability to see pending invitations. The ability to delete either pending invitations or current members. Does anyone know of any existing snippets that I could implement for this front-end functionality?

Is this a bug or why does white get printed to console twice but black only once in the below code? If I take out the Text() call then it works like I expect (both onAppear modifiers only called once).import SwiftUIstruct ContentView: View { var body: some View { ZStack { Group { Rectangle().fill(Color.black) } .onAppear() {print(black)} Group { Rectangle().fill(Color.white) Text(black on white).foregroundColor(.black) } .onAppear() { print(white)} } }}struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() }}

Hi all, after I pushed the build on testfight but I cannot add the build to groups for internal testing. Please help to addvice

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!
