A Summary of the WWDC25 Group Lab

selecting the Facebook app from the FamilyActivityPicker returns an ApplicationToken. When adding that token to a ManagedSettingsStore's shield.applications set, both Facebook and the Facebook Messenger Kids apps gets shielded, even though the latter was not selected from the picker. (Interestingly, the Facebook Messenger app does not get shielded - just the kids version) The same is true for shielding the ApplicationToken produced by selecting the Amazon app. It causes the Alexa app to be shielded. I assume this is occurring because the apps share a keychain group, bundle id substring, or some other property that the picker is using, but how can I avoid this behavior?

I am currently having a nightmare with Xcode trying to set up App Groups I previously had it set up but since I upgraded to Xcode 7.3 it has now broken. I get the error message You don't have sufficient permissions I haven't enrolled in the developer program but I know app groups you don't need to use them. This is what is shown inside Xcode inside the permissions.Image of problem

I am using SharePlay and the Group Activities framework in my app and my usecase requires the number of participants, so I am trying to get it like this: _ = SharePlayManager.sharedInstance.groupSession?.$activeParticipants.sink(receiveValue: { participants in print(participants.count) }) But this always prints 0, am I doing something wrong? (groupSession is 100% not nil)

Hello, I have multiple apps that i would like to login with apple login connected to same backend. I enabled sign in with apple on all and told them to group with primary app id which is one of them. I went and created 1 service id and key and used that on the backend to login the user. I can login fine on the primary app id but not on the grouped ones. Am I missing anything setup wise?

Hi, I have an app group that worked fine between my watch and iPhone using Swift 1. Now, however, nothing is saving to my app group when I use the same code to save and synch the data (and thus nothing appears on my watch).I believe the relevant code is here://in the AppDelegate var sharedData = NSUserDefaults(suiteName: group.RxRemindMe)//in my VC NSKeyedArchiver.setClassName(RxRemindMe.Medication, forClass: Medication.self) NSKeyedUnarchiver.setClass(Medication.self, forClassName: RxRemindMe.Medication) appDelegate.sharedData!.setObject(savedAsData, forKey: TheMedicationsShared) appDelegate.sharedData!.synchronize()if I run the same .setObject command on a non-shared userDefault object, I see bytes saved (size changes to some positive bytes) and my phone app can access the data. However, when I execute line 4 above via the shared group object, the object remains nil in size and nothing has changed. I thus can't recall the data either on the phone or on the watch. Is this a bug in

I am unable to add a Group to my app's TestFlight build. Steps: In App Store Connect, Go to TestFlight > Build # > Add Group (Group + button) Add 'Export Compliance Information' Click on 'Start Internal Testing' When following these steps, the entire screen reloads, however navigating back to the same screen shows that no Groups have been added to the build. A friend who is on the same account is able to follow these steps successfully. Is there something we should be checking to allow me to do this?

I'm Trying add SwiftUI to Old Project. But Error in Group. How do I solve this problem? My Project: Xcode: 12.5.1 iOS Deployment Target: 13.0 Swift Compiler Error Static method 'buildBlock' requires that 'Group' conform to 'View' Trailing closure passed to parameter of type 'NSManagedObjectContext' that does not accept a closure

Howdy, My macOS application uses app groups, using an entitlement file similar to the one below. com.apple.security.application-groups $(TeamIdentifierPrefix)com.example.test This all works when using my local Xcode. However, when I push the job to our CI/CD server I get an error. error: Provisioning profile doesn't include the com.apple.security.application-groups entitlement. Profile qualification is using entitlement definitions that may be out of date. Connect to network to update. Searching around, namely macOS Unsatisfied entitlements com.apple.security.application-groups and System Extension app-group entitlement issue tells me that I do not need to have the app group contained within my provisioning profile, due to how macOS handles App Groups differently to iOS. Is there a way to tell xcodebuild on my CI box to ignore this and continue building?

Hi everyone, I'm facing an issue where I cannot write a file to a shared App Group container in my tvOS app when running on a real device. My code works perfectly on the simulator, but fails on a physical device with a permissions error. I’ve set up an App Group with a custom identifier (e.g., group.), and it’s correctly configured in the Capabilities section of Xcode for both my main app and widget targets. Here’s the code I’m using to save a test file: func saveTestFile() { guard let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: group.) else { print(Couldn't access the Group URL.) return } let containerURL = groupURL.appendingPathComponent(Library, isDirectory: true) if FileManager.default.isWritableFile(atPath: containerURL.path) { print(Directory IS writable) } else { print(Directory IS NOT writable) } let fileURL = containerURL.appendingPathComponent(test.txt) let content = Hello App Group! do { try content.write(t
