Documentation for group subscription renewals
I just caught the video for group and organization subscriptions. I haven't yet found documentation that describes how renewals work for the auto-renewable subscriptions when bought for a group. To reuse the video example of a run club, a coach might get a bulk of subscriptions for the team, for that season (or year). The next year might have a different number of club members, a mix of both new members, as well as some lapsed ones. The MDM portion talks about seat assignment so I think that would cover it for organizations, but what about groups?

Xcode file template with groups
Hey,I'm attempting to create a File Template that contains folders. Take the structure below as an exampleMyFileTemplete.xctemplate TopLevelFolder SecondLevelFolder - class SecondLevelFolder ThirdLevelFolder -classIf I just setup a template and add my folders and classes it works but when it adds to the project it addes them as File Referance(blue folder icon).Is there any way to add the folders as a group?EDIT: I'm looking for a way simialar to the project template where you use Definitions and node keys to create groups. This doesn't seem to translate over to the file template.<key>Definitions</key> <dict> <key>hello.h</key> <dict> <key>Group</key> <string>Supporting Files</string> </dict> </dict>BooRanger

Regex Conditional Group ?
Looking at this article ... https://www.codeproject.com/Articles/21080/In-Depth-with-RegEx-Matching-Nested-Constructions, where it says The Push-down Automata roughly 1/4 way down, although am not sure the same will be using Swift. Apparently using (?<S>Agora)(?(S)(?!)|(.*)) should work but does not.Any suggestions for using conditional group ?

Group leaderboards not in sync
Can someone explain to me how group leaderboards are supposed to work?I have a game that has been live on iTunes for about a month, and it has 16 leaderboards (all full with scores now).I decided that I wanted to create a free version of the app, that shares the same leaderboards.So, I changed the leaderboards the paid app uses over to a group, and updated all the leaderboard names with grp.*. That change is now live, and everything is looking great, the leaderboards are still full with scores.Now, yesterday, I released the free version of my app, also using the group leaderboards. It took all day for the app to finally show up in the appstore. This morning, when I downloaded the app, and looked at the leaderboards, they are empty, except for a few scores.I know the code is pointing to the exact same leaderboard names, as the 2 versions of the game are built from the same exact code. I double checked itunes connect, and it shows the 2 apps are sharing the same group leaderb

WatchKit groups layout questions
Hi,I've started working on my first WatchKit app UI, and I've run into some things that I don't know if it's possible to solve in WatchKit without using SwiftUI (or at all):1) Is it possible to have a group element that's sized to fill all remaining space? E.g. have a vertical group set to fill whole screen height, one label at the top and one at the bottom, and some group in the middle automatically taking the space that's left between them. Or a horizontal group filling the screen width, with a label on the left and right and a spacer in between that uses whatever space is left.2) Is it possible to configure a group or another element to keep a constant aspect ratio, i.e. its width relative to its height or the other way around? E.g. to have an element configured to fill the screen width, and to automatically have the same height as the width, so that it always stays a perfect square.

Unable to submit already approved subscription groups with error "New subscription groups must be submitted with an auto-renewable subscription from within that group.
Issue: Since Sept 10, 2026, my existing, already-approved auto-renewable subscription group cannot be submitted for review. This is not a new group: all 9 subscriptions in it show Approved, and my app has been live since July 2026. How it started: I changed only the introductory offer (7-day to 14-day free trial) on the monthly products. What App Store Connect shows now: The group is marked “Prepare for Submission” with the banner “Your first subscription group must be submitted with a new app version.” The Draft Submission contains only the group, and Submit for Review is disabled with: “New subscription groups must be submitted with an auto-renewable subscription from within that group.” “Add for Review” is greyed out on every one of the 9 subscriptions, so there is nothing to add to the draft. Impact: I can’t sell a subscription on any tier or billing period, and it has now been 6 weeks of lost revenue. Not the app binary: Builds 497 and 501 we

Needed Actions for Group Feature
Hi! The app that I am building has the ability for users to join and be added to groups. Are there any requirements from Apple beyond the ability to leave and report the group that the user must be able to do? I read through the developer guidelines but I just wanted to make sure before submission. Thank you!

CFPreferencesCopyKeyList for App Group
We use AppGroups to share information between app and extension.I need to get list of keys stored in the defaults. There is a method 'dictionaryRepresentation' which returns all keys and values. I'm worried if retreiving all values shoots up memory.There is a method in Core Foundation that only get's the keys, which I plan to use.CFArrayRef CFPreferencesCopyKeyList(CFStringRef applicationID, CFStringRef userName, CFStringRef hostName);I need help with the arguments.applicationID is the App Group bundle identifier.What should be used foruserName - kCFPreferencesCurrentUser or kCFPreferencesAnyUserhostName - kCFPreferencesCurrentHost or kCFPreferencesAnyHostThanks in advance

Reply to Adapter Problem - compatibleAdapterNotFound
@alex_und3r, as we announced at WWDC26, custom adapters are unfortunately no longer supported as of OS 27. Instead, you can use the base machine-learning models that are available on people’s devices or provide your own custom models using Core ML or Core AI. Background Assets remains a great way to deliver custom models to your users.
