“A Summary of the WWDC25 Group Lab”

I am adding Group Activities integration with a MacCatalyst app. I have added the Group Activities entitlement in Xcode. I also checked the entitlements with : codesign --display --entitlements :- I can see the entitlement : com.apple.developer.group-session The feature work fine on iPadOS but when I run it on MacOS, the GroupActivitySharingController is not loading properly. I get the following error messages: Cannot run query EXQuery: extension point com.apple.groupactivities platforms: 6 with error: (null) Failed to lookup extension with query EXQuery: extension point com.apple.groupactivities platforms: 6 on <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to fetch config for hostViewController <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to build remote hostViewController for <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250> Failed to fetch extensionViewController Calling -viewDidAppear: directly on a v

In the 2020 WWDC changes to the Developer site, the section in Profiles for Keychain Access Groups went away. I understand that this entitlement is now rolled into App Groups, but I don't see my preexisting Access Group identifier listed on my page anymore. Where do I modify or remove the Access Group entitlement I've been using, or create new ones?

Hello, I am using compositional layout to create list of objects. I have followed the official documentation and tried the provided sample here: https://developer.apple.com/documentation/uikit/views_and_controls/collection_views/implementing_modern_collection_views However, I have seen something weird with the ListAppearancesViewController. When I use the sample as provided (initial appearance is set to plain), if I change the appearance to grouped by clicking on the bar item, the height of the header is displayed according to the label: But if I change the initial appearance in the code to grouped or insetGrouped, the height is higher: Which one is the correct behavior? Having this space or not? But with this space, the accessory is not vertically aligned with the header, which is weird. How to solve that? Thanks for the help! Nghia

I'd like to know if there is a way to limit the number of participants in a group activity (SharePlay). Looking through the API, I could not find anything regarding limiting or requiring the number of participants.

My application uses a group container that shares files between the main application and its helper. The helper is launched by using SMLoginItemSetEnabled. When I switch to xCode 7 and build the project, I get an error :error: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier. Embedded Binary Bundle Identifier: X2RD457E37.com.myCompany.myHelper Parent App Bundle Identifier: com.myCompany.myAppSo far, the bundle’s name of the helper started with the the group container ID (X2RD457E37). Did this rule change ? I have found no documentation on the subject.I develop in Objective-C but I notice that with Swift the method SMLoginItemSetEnabled is no longer avalaible. I guess it was replaced. But by what?Thanks for any help.

I was watching the WWDC video about iMessage apps, part 2 and was a bit surprised by the section about group conversations. It's between 36:20 and 38:20 in this video: https://developer.apple.com/videos/play/wwdc2016/224/I was a bit surprised by that and I don't understand why an app can't have access to all messages in the current session. Not the entire conversation, but just the current session. They all belong to the app so why would the app not be allowed to have access to all messages in that session? It should be made available through the MSSession object if you ask me. Or am I missing something??I understand what he means by using the cloud but it feels like a bit of a hack to me.
