Multiple Subscription Group Approvals
My app creates new subscription groups via the app store connect api. Our end users subscribe to creators. Each creator has their own subscription group within app store connect. We will create hundreds, even thousands of subscription groups via the api over time. Does Apple have to approve each subscription group before they can be accessed via the app by end users? Or do they just approve the first one and allow us to create new subscriptions groups in real time -- over time via the API without additional approvals?

Reply to Core Data Predicate - Table View Display Format
The code in the previous post wasn't presented for copy/pasting, it was presented as an example of the idea.The thing is, if this were a classroom assignment, the purpose of the assignment would be:Use sortDescriptors on an NSFetchRequest to group the fetch results by name.Instead of displaying the results of the fetch request directly, display one section and for the rows display information from the groups of the fetch request.Or, as a variation to the second bullet point, instead of displaying the individual rows, initially display a single row displaying summary information for the group which is replaced by the individual rows when expanded.But all of that still boils down to:Step 1: Sort your fetch request by name.Step 2: Customize your table view code in a manner that goes beyond the scope of a single forum post.As a good start, the table view and collection view sessions from each year's WWDC videos explain how to do this sort of thing, things like dynamically addin

Reply to SwiftData in-memory ModelContainer causes DefaultStore validation errors on consecutive xcodebuild test runs
Thanks. The issue does seem to be a bug... Do you have a feedback report yet? If not, would you mind to file one with the information you provided here, and share your report ID here? Thanks. As a reminder, WWDC26 is right around the corner, and folks probably won't be able to be as responsive as before. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Create hidden users group from terminal
Hi, I need to create a new users group on macos (version 10.15 and up) from terminal or from swift. The group must be hidden, not be displayed into System Preferences, similar to www group for example. I've found 2 ways to create a group from terminal: dscl and dseditgroup, but in both cases the created group is visible into the Users and Groups list from System Settings. Any suggestions how I can hide the group? Thanks

Wednesday Education and Enterprise Deployment and Development Lab Notes
Question:How does the MDM command to Install major update force macOS Sierra upgrades on DEP-enabled Macs?Is the user asked to authorize the upgrade, or does the upgrade happen with or without user consent?Answer:It downloads the OS installer from the MAS, and triggers the startosinstall command line tool.It behaves like a restart-required software update:If the user is logged-in and there is unsaved data, it will nag you that there is a pending software update and to please restart.If nobody is logged-in (i.e. at loginwindow), the OS upgrade starts without user intervention.Question:Can both the ALF and PF firewalls be configured via MDM?Answer:Yes, with caveats. Refer to Sierra's Profile Manager for the currently supported functionality.Question:Are the ALF and PF firewalls configured via Profiles (.mobileconfig) or directly via MDM commands?Answer:Configuration profile (.mobileconfig file)Question:Can firewall logging also be configured this way? If so, can the new log command line utility see the logs, so

How to use multiple Vive headsets in one Mac computer lab
Greetings! I am a professor of Italian Renaissance architecture and urbanism, and my question relates to a course I'd like to teach on the canals of Venice. Part of the course would be in our Mac lab (furnished with 15 2014-2017 iMacs), where I would like each of my 15 students to edit a single 360 video of the canals using the Immersive Environment feature in Premiere Pro / After Effects while wearing Vive headsets. According to Adobe, our iMacs fit the system requirements for using Premiere Pro and After Effects with the Vive; according to HTC, they're positive that I can do this but aren't authorized to tell me how (they also want me to reach out to HTC Arcade...?).I'm planning on installing Mac SteamVR on, and hooking up a Vive headset to, each of the computers. Thunderbolt 2 is the fastest connection on our iMacs, so I was planning on hooking up the Vives to a thunderbolt 2 to HDMI/USB adapter. I don't think I need external GPUs, because each student will only be editing/watching one 360 video (

UserDefaults and App Groups ID
Is it a bad idea to use the App Group ID as an UserDefaults' suiteName? This seems to be a general aproach I see on code bases out there. When using the App Groups ID as a UserDefaults suiteName: extension UserDefaults { static let shared = UserDefaults(suiteName: group.com.example.app)! } I'm getting this warning/error: [User Defaults] Couldn't read values in CFPrefsPlistSource<0x000000000> (Domain: group.com.example.app, User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd An App Groups ID with the same String (group.com.example.app) is defined in Signing & Capabilities > App Groups. If I change the suitName or change the App Groups ID the warning goes away. Is it not a good idea to use the App Group ID as an UserDefaults' suiteName? Does anybody had the same problem? I searched everywhere about thi

Bluetooth sync contact group
In iOS 10 Beta 7 how do you sync only selected contact groups via Bluetooth to car system? In iOS 9 (and earlier versions) under the Bluetooth settings you could see, and select, individual contact groups but under iOS 10 there is only the option to select 'All Contacts'.

EventKit Reminders Groups?
I've looked around quite a bit at the EventKit documentation and done all the searching I could think of, as well as examining the EKCalendar and EKEventStore types. Trying to find out how to view, modify, and create groups of reminders lists.
