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

Hi,We've got an App ID that's been around for a substancial amount of years now. Being in the process of developing new features I've tried enable App Groups service in developer portal for this AppID, but the checkmark is disable (i.e. not clickable) for this particular App ID. I can enable the service for other App IDs that were creared recently. I'm stuck wondering how I might start investigating the root cause for why App Groups are not available.Does anyone has an insight about what the root cause might be or what kind of diagnostics exist for me to investigate the issue?Thanks,Dmitry

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

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?

We have a macOS app that has a Photos Extension, which shares documents with the app via an app group container. Historically we used to have an iOS-style group identifier (group.${TeamIdentifier}${groupName}), because we were lead by the web interface in the developer portal to believe this to be the right way to name groups. Later with the first macOS 15 betas last year there was a bug with the operating system warning users, our app would access data from different apps, but it was our own app group container directory. Therefore we added a macOS-style group identifier (${TeamIdentifier}${groupName}) and wrote a migration of documents to the new group container directory. So basically we need to have access to these two app group containers for the foreseeable future. Now with the introduction of iOS-style group identifiers for macOS, Xcode Cloud no longer archives our app for TestFlight or AppStore, because it complains: ITMS

Hello. I need your help. We are developing an application where users provide premium content. Followers have to subscribe to each user's account to access their content through a renewable subscription. Like on Twitch application. Example: User 4 can subscribe to user 1, user 2 and user 3. He will pay every month, 3 subscriptions. The problem is that we can't create all the subscription groups manually because it would be too much work and not scalable. According to the documentation, if we have 1000 premium users (who sell their content), we have to create 1000 subscription groups manually and submit the application for each new selling user. How does Twitch make it possible for a user to subscribe to several accounts at the same time? Can I find documentation on this subject? Thanks in advance.

IOS WhatsApp app does not realize the WhatsApp group Joined caller's details.

I'm not sure if this is even the right place to ask this, or voice this complaint if there's no fix. If not, please direct me where to go. I'm trying to switch all my development over to Safari, but the tab sidebar is driving me absolutely insane. Let's say I have a bunch of tab groups expanded, and I collapse the sidebar to focus on the webapp I am building. When I toggle to show the sidebar again, every single tab group is collapsed. Why is it 2 clicks to see the tabs in the sidebar? Even with zero tab groups, and just tabs in the workspace, if you collapse the sidebar it'll collapse the list of tabs. Is there some hidden setting for this? Who do we have to complain to?

I have trouble with reading a file from an App Group with my System Network Extension. The app group container is found successfully. However the file read returns empty. In the app itself the same code runs fine and returns a string array of items found in the file. Code: func readFile() - [String] { var jsonResult: [String] = [] guard let containerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: AppConstants.groupID) else { fatalError() } let fileURL = containerURL.appendingPathComponent(file.json) if let data = try? NSData(contentsOfFile: fileURL.path, options: .mappedIfSafe) as Data { if let json = try? JSONSerialization.jsonObject(with: data, options: .fragmentsAllowed) { jsonResult = json as! [String] } } os_log(jsonResult: %{public}@, jsonResult) return jsonResult } Log: default 09:42:19.486793+0200 app-network-extension container_create_or_lookup_app_group_path_by_app_group_ identifier: success default 09:42:20.105792+0200 app-network-extension jsonResult
