A Summary of the WWDC25 Group Lab

Do App Groups still work on Watch OS 2 as a mechanism for sharing files between the watch and iPhone?(Since WatchKit extension will now reside on the watch instead of the iPhone)What changes to we need to make to the existing codebase?

Prior to Sequoia, Mac Catalyst Apps worked fine when using group folders that started with group. They now get an alert that the Mac Catalyst app is trying to access data from other applications. This may also impact some SwiftUI developers. According to this the documentation for the App Group Entitlements entitlement, on macOS we should begin use the Team Identifier instead of group. Should Mac Catalyst follow the macOS or iOS rules for com.apple.security.application-groups? If they should need to follow the macOS rules now, that creates several issues for developers. We would now need separate build targets to pick up the different Entitlements files. More distressing is that we would need to do some kind of migration process to get our files to the new location. There wouldn't be a transparent way to do so where the user wasn't warned about the application accessing files that don't belong to it. Any clarification on what Mac Catalyst developers should be doing

If I only have one product item in Apple Pay, how would I detect a total? My app is a donation platform, so I don't need to actually ship anything, but would like contact info. I have a number of errors that I have tried to figure out to debug to no avail. Any help is appreciated.Also I keep getting this error (this was the same as the sample code given from WWDC).This is in my BuyTicketViewController.swift file. if PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(BuyTicketViewController.paymentNetworks) { let button = PKPaymentButton(type: .Buy, style,: .Black) button.addTarget(self, action: applePayButtonPressed, forControlEvents: .TouchUpInside) button.center = applePayView.center button.autoresizingMask = [.FlexibleLeftMargin, .FlexibleRightMarin] applePayView.addSubview(button) } }The error says 'expected declaration.'The sample says to use else (for traditional checkout). When I put that it, it breaks the rest of my code and I get lots of errors.line 8 - eror on MerchantIDline 9 - error

I am developing a Mac app that makes use of App Scripting. The is Sandboxed and thus needs the proper entitlements in order to get permissions to send AppleScript events to other apps. I have gotten this working properly for apps (like Mail and spotify) which specify access-group identifiers like this:<access-group identifier=com.apple.mail.compose access=rw/> <access-group identifier=com.spotify.playback/>However, a few other of the Apple made apps (like Xcode) specify their identifiers like this:<access-group identifier=*/>I have tried to configure my entitlement file like this:<key>com.apple.security.scripting-targets</key> <dict> <key>com.apple.dt.Xcode</key> <array> <string>*</string> </array> </dict>, but when doing this it does not work and I get this error message in the console:AppleEvents/sandbox: Returning errAEPrivilegeError/-10004 and denying dispatch of event xcod/buld from process '

Hi, would someone help me get started on a problem in iOS using Swift? How do I get all the groups that a unified contact belongs to? Or how would I check to see if a contact is within a group? That would allow me to find out all the groups that a contact belongs to. I suspect what I need to learn is how to create the predicate to set the predicate property of a CNContactFetchRequest that I need to use.Any help will be appreciated.

Is it not possible to test Group Activities without a paid developer account? I don't see Group Activities in Signing & Capabilities in Xcode. I'm looking to try adding support for my app but unable to try this myself and just seeing if I need a paid developer account to do so?

I recently changed my developer account from account A to account B. I have successfully transferred my applications. With transfer of applications my app group was not migrated. Question - Can I deleted the app group from account A and recreate it in account B with the exact same identifier. If means does it affects the live users. Which means does the live user can able to use our application without any data loss(Logout)

So I only recently uncovered the Contacts Framework through this video: https://youtu.be/sHKir2ZMk5Q. As such I'm not yet accustomed to the API. Basically my main problem is that I can't seem to find a way to access the name of the group a CNContact is in. The only support I can find is in Apple's own documentation, which isn't very helpful. if someone could point me in the right direction towards how to print the group name, I would be very grateful. My code is below, Cheers // ModelData.swift // B-Day import Foundation import Contacts import SwiftUI struct Contact: Identifiable { let id = UUID() let category: String let firstName: String let lastName: String let birthday: DateComponents? } func fetchAllContacts() async -> [Contact] { var contacts = [Contact]() let store = CNContactStore() let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactBirthdayKey, CNContactIdentifierKey, CNGroupNameKey] as [CNKeyDescriptor] let fetchRequest = CNContactFetchRequest (keysToFetch: keys

<key>Entitlements</key> <dict> <key>application-identifier</key> <string>A1B2C3D4E5.com.example.myapp</string> <key>aps-environment</key> <string>production</string> <key>get-task-allow</key> </false> <key>keychain-access-groups</key> <array> <string>A1B2C3D4E5.*</string> </array> </dict>Would using a wildcard keychain in two shared Apps from the same publisher mean that each app can access every keychain item of the other?ie. if A1B2C3D4E5.com.example.myapp and A1B2C3D4E5.com.example.myOtherApp had the keychain groups as defined above, then would each of them be able to access ALL of the keychain items of the other? even the ones stored under the group A1B2C3D4E5.com.example.myapp or A1B2C3D4E5.com.example.myOtherApp?

For the current app, I can get the Application Scripts directory with FileManager.url(for: .applicationScriptsDirectory, in: .userDomainMask, appropriateFor: nil, create: true), but I cannot find a similar API for application groups. Does one exist, or do I have to construct the URL manually? That would probably be ~/Library/Application Scripts/[app group id], but there doesn't seem to be a FileManager API to access ~ either, as FileManager.default.homeDirectoryForCurrentUser returns /Users/username/Library/Containers/[app id]/Data/.
