A Summary of the WWDC25 Group Lab

Hello! I am attempting to add Subscriptions to an App that Is already published on the App Store. I cannot get Xcode to actually sync what is in my App Store Connect. When adding the Storekit configuration file, I go through the automatic linking process and select the proper bundleID. The configuration file says 'Synced @ [CurrentTime]' however there are no subscriptions listed in there. I have attempted deleting the file several times, creating a new subscription group. With no success. Do I need to publish the subscriptions without the features first? Upon attempting to write the supporting code that will enable these features within the app, I cannot get Xcode to identify that I have these subscriptions. I have also tried pushing these to TestFlight, still with no success. Thank you.

Hello everyone, For example, our app currently has one subscription group in App Store Connect with 5 plans (2 annual, 2 monthly, and 1 quarterly). By default, users can go into Apple Subscriptions in Settings and freely switch between all of these plans. However, our business requirement is to only allow users to stay on one annual plan and one quarterly plan. We don’t want them to switch to the other plans. My questions are: Is there any best practice or recommended approach to restrict subscription switching within the same group? Would removing the unwanted products from sale be the correct approach, or are there any risks/downsides with this method? Has anyone faced a similar situation and found a practical solution? Any guidance or shared experience would be greatly appreciated. Thanks!

Hi! I wrote an internal used backup command line tool which is in use since several years. Today I got an error while sending an email: “Failed: ioOnClosedChannel”. I assume that the latest macOS updates did break my app. On the server I use macOS 15.7 and on my development machine macOS 26. Here is the related code: private func sendMail() { var a : [Email.Attachment] = [] if self.imageData != nil { switch self.imageType { case .tiff: a.append(Email.Attachment(name: Statistics.tif, contentType: #image/tiff#, contents: ByteBuffer(bytes: self.imageData!))) case .pdf: a.append(Email.Attachment(name: Statistics.pdf, contentType: #application/pdf#, contents: ByteBuffer(bytes: self.imageData!))) case .unknown: fatalError(Unimplemented attachment type!) } } mailHtml = mailHtml.replacingOccurrences(of: , with: n) let email = Email(sender: .init(name: Backup, emailAddress: SENDER@MYDOMAIN), replyTo: nil, recipients: recipients, cc: [], bcc: [], subject: self.subject, body: .universal(plain: self.mailText, html: mailH

The problem is described in full with log output in #16844 We are having an issue with TCC prompting users for access to the app group container despite signing with entitlements following all guidelines. This is a regression from the Feb 2025 Changes discussed in App Groups: macOS vs iOS: Working Towards Harmony The problem can only be reproduced with Xcode 16.0 and later. The entitlements for the app include access for the group container with [Key] com.apple.security.application-groups [Value] [Array] [String] G69SCX94XU.duck The documentation notes the group name can be arbitrary, e.g. .. Cyberduck uses G69SCX94XU.duck by default. Interestingly enough the alert is not shown when a group name matching the bundle identifier is used, e.g. G69SCX94XU.ch.sudo.cyberduck.

Hi! For the past few days I have been experiencing slower builds in my workflows, without a clear reason of the cause as sometimes they run with the old usual time. I tried contacting the Developer Support without success in finding out the reason of these issues, the case number was 102661768064. As an example, I have a workflow for Pull request checks that involves testing and analyzing. This usually ran for 11-15mins, but now it could take up to 30mins or more. Looking into the logs it just seems that the machine it's particularly slow, then in another build it goes with usual times again. As an example, below are the summaries of two builds of the same branch: Being in the free tier, these new long times are burning my free time quite faster and probably will need to look into running this checks in GitHub Actions if it doesn't improve. A hint of what might be wrong is also found in an error in the test workflow, which denotes a problem booting a simulator. Any help on this will be appreciated, t

Hi, I just released a new version of an app that was transferred from another developer account. The previous version of this app used the App Groups feature to store some important data, and I would like to retrieve that data. In the new version, I’m using the same bundle identifier and the same App Group ID (which has already been deleted from the original developer account). I also added the App Groups entitlement in the project settings and set the same App Group ID. However, I still cannot access the data in the App Group. From the documentation and issues I’ve found, it seems that an app should still have permission to access the same App Group after being transferred. Did I miss something? Thanks!
