How to create and assign app groups
Hello,I'm trying to automate the creation of app groups for a given bundle id. I've checked the documentation but there are no information regarding what to do to create a new app group identifier and how to connect it to a bundle identifier.I can only enable the APP_GROUPS capability (https://developer.apple.com/documentation/appstoreconnectapi/enable_a_capability) but then there doesn't seem to be a way to assign an app group to a bundle id.The modify capability endpoint (https://developer.apple.com/documentation/appstoreconnectapi/modify_a_capability_configuration) seem promising but there's no documentation regarding the format of the request, and after trying to list the information for a bundle identifier (https://developer.apple.com/documentation/appstoreconnectapi/list_all_capabilities_for_a_bundle_id) with a manually set up bundle identifier with an app group in the developer portal, the API doesn't even return the app groups for a bundle identifier with t

AU Lab midi mapping (host automation?) broken?
Or did it ever work? I just started trying to get a small setup with a single AU happening. I can play notes and assign midi CC #s to parameters in a plugin, but Command-clicking to open the midi mappings window does only that – I move a midi control as it directs but nothing happens. Notes no longer play and the application is not responding. Clicking cancel in the midi mapping window results in a beachball and I have to force-quit. I've had zero luck with multiple google searches on a variety of terms, so I'm posting here. TIA for any help! I have the latest AU Lab (2.3, created March 6, 2020) on a fresh install of Mojave (10.14.6). BTW - I am assuming, perhaps incorrectly, that midi mapping and host automation are the same thing. Maybe I need to be set straight there. I'm curious though – if Apple means this program to be a test bed for AUs that devs build, how could it not have some way to test host automation? This makes no sense to me.

App Group File Ownership
Files can be written and read from the App Group by multipler apps. When an app is removed, its files are also removed.It looks like files in the App Group folder are owned by the app that created them. So, if app A adds a file to the App Group and then app A is removed, the file in the App Group is also removed. If App B reads that file, it better deal gracefully with it disappearing.What if a file in the App Group is created by app A and then modified by App B? Does ownship transfer to app B or remain with app A? If app A is removed after app B modifies the file, will it be removed?

Sign In With Apple and App Grouping?
Sign In With Apple has a group apps category: https://help.apple.com/developer-account/?lang=en#/dev04f3e1cfcHowever, thats the only information I could find for sign in with apple and group apps.What is the significants of group apps with sign in with apple? What does it do? How does one use it?Does it support the following use-case?: I have a primary app and a child app. If I sign in with apple with the primary app, and then i want to use the secondary app, do i have to sign in again? Or am I already signed in because I have signed in with the primary app? Or can I architect it in such a way that allows me to sign in to one of the grouped apps, and then stay signed in when using another grouped app?

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?

Xcode Expands All Groups
Hi!(In advance I'm using Xcode 9.2 (9C40b))Xcode is great but one thing that grids my gears, is that whenever I add something(New file, Group, etc) to the file tree all groups gets expanded😢 This gets really annoying beacause of having multiple groups and having to minimize everything over and over again.I can't be the only one with this issue, or am I doing something wrong?If this is just a bug in Xcode, is there a future update coming to fix this?Regards/Guthner

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 (

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

Seems that the groups are gone for the External testers??!! Such a nice feature to organise a little bit things in my list of testers. Now, all of a sudden the groups are gone? Why?

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'.

Reply to InferenceError referencing context length in FoundationModels framework
You can use the Foundation Models instrument, in the Instruments app, to analyze the use of the framework and details about your session: it features a column reporting the number of input and output tokens, which you might want to check to see if they're consistent with your expectations. This WWDC25 video can be useful too.
