Removed user from one testing group, removes the user ability to see the app in other groups
we have an app in App Store Connect; we have 4 External Testing groups; we have testers, who are simultaneously in two or more groups; tester who consists in several groups can see all available builds in these groups on their device via TestFlight; I choose to remove the tester from one group; check this group - the tester is removed; check other groups - the tester remains in other groups; but checking the TestFlight on the device shows tester removed and NONE of the builds available before can be seen now. According to this article: Removed testers will no longer have access to new builds added to this group in the TestFlight app. They’ll continue to have access to existing builds until they expire, but in fact we can see opposite behavior and the tester looses access to ALL groups and builds in TestFlight after being removed just from one of the groups. So the question is: is there a way to fix this? Or we m

App Groups and UIImage
I want to transfer a UIImage from the main application to my keyboard extension (in Swift). The only way I can think of to do this is by using app groups. (If there's another I'd love to know 🙂 ) Does anybody know how this would work? Do I need to use Core Data? Thank you!

Tuesday File Systems Lab Notes
Question:Can an APFS container span multiple physical devices?Answer:Not right now. Apple's looking at that, in relation to Fusion drives. No RAID or RAID-like support is planned for APFS.Question:How does CoreStorage interact with APFS during the APFS conversion process?Answer:The plan is to have the APFS conversion process read the Core Storage plus HFS+ metadata and convert them to an APFS container. For encrypted Core Storage volumes, you will likely be prompted for an account password or recovery key before the conversion process begins.Question:Is fdesetup going to be the tool for interacting with APFS encryption, or will there be a new command line tool for managing APFS encryption? If there's a new tool, what is it?Answer:To be determined because Apple still looking at this.With regards to encryption, Apple has started work on this part of APFS but the work is not yet complete.Question:Can APFS recovery key(s) be escrowed when enabling encryption? The goal is to store the recovery key(s) somewhere for

App Groups names are red
I have recently restarted an old code base. The app uses App Groups to communicate with network and endpoint system extensions. For some reason, in Xcode > Target > Signing & Capabilities the app groups are showing up with red text. I feel the red signifies a problem, but I cannot figure out what it is. The app compiles and runs, but I feel there is problem that I am missing. Any idea why App Group names would be displayed in red?

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

Initiating group facetime WatchOS
Is there are URL scheme available to WatchOS that will start a group call? The facetime-group prefix prompts the user to start on iOS, but is unsupported on watchOS. Additionally, on WatchOS, the user can manually select contacts to add to an existing facetime audio call. URL scheme example that worked on iOS: facetime-group://?remoteMembers=+12345678901;+23456789012&isVideoEnabled=1 Console warning when attempting on WatchOS: -[SPApplicationDelegate extensionConnection:openSystemURL:]:2418: URL with scheme facetime-group not supported.

Apple Watch Group Notification
I recently moved my watch app from InterfaceController to the SwiftUI LifeCycle, but I've encountered some issues. In my app, I'm using group notifications. Before I moved to the SwiftUI LifeCycle, when I received a group notification with the same thread identifier, it appeared as a stack in the notification center of the watch. When I touched the stack, it extended with individual notifications. However, after moving to the SwiftUI LifeCycle, when I touch the stack, it only shows the first notification of the stack and doesn't display the extended notifications. Do I need a custom group notification view in the SwiftUI LifeCycle, similar to the Message App? Is there any other way to use the previous static group notification view? Please help me!

imessage group chat confusion
So I am in a group chat with my family. We’ve had this groupchat established for a long time, and none of us have ever added anyone else to it. Somehow last night, a different family member joined our group chat and started texting us, but none of the original chat members added her, not even accidentally. This is the second time this has happened, and we have no idea how they are inserting themselves into our group chat. We are all iphone users, including the person that is somehow adding themselves to our group chat. All of us use different Apple ID accounts as well as different phone numbers, and that’s the same for the person adding themselves, so I’m truly at a loss for how this is happening.

What is the point of thread-id/grouping in push notifications if grouping depends upon user preferences?
There's plenty of articles out there about programatically grouping push notifications. However I have tried setting the thread-id in the push payload when sending a push, or setting the threadIdentifier for a received push in a notification service extension to be the same for several pushes. But if within the iPhone Settings / Notifications the user selects to display pushes as List and turns off Notification Grouping, then each notification resulting from the push appears on its own separately. Is there something other than thread-id/threadidentifier that is used to programmatically group them? If not then whats the point of these as grouping and display is actually under the control of user.

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.

Group Activity and AVAudioSession
For an App in the PlaybackAndRecording Category, would entering a Group Activity Session change the Category and Mode since FaceTime is ongoing? will we still have access to Microphone locally using, e.g. AVAudioEngine? if yes, will the presence of FaceTime force VoiceChat mode and VPIO in our session? Thanks in advance.
