Default payment method option bug?
Hi team at Apple, here is a scenario we came across: The order of priority of payment methods in Apple Wallet follows: Credit Debit Apple Cash Our app displays a payment sheet that excludes credit cards. Instead of a debit card, the default payment option shown to the user on the payment sheet is Apple Cash. Is this a known issue or have we configured something wrong in our end?

Does apple make commission on payments made to peers using external processing like Stripe for physical services
So I'm wondering if Apple makes commission on those payments since they're made in the app. For example a user may pay another user to clean their car. This will be handled with Stripe Connect and their balance, payment history, etc will be displayed in the app. Does Apple charge commission on that? The section the app review guidelines that I'm refrencing is below, but I'm still a little confused. 3.1.3(e) Goods and Services Outside of the App: If your app enables people to purchase physical goods or services that will be consumed outside of the app, you must use purchase methods other than in-app purchase to collect those payments, such as Apple Pay or traditional credit card entry.

What are the criteria for CLVisit in CoreLocation?
There is no official documentation specifying the exact criteria for determining a CLVisit. For example, if a user starts at a target location, will the following method be called? func locationManager(_ manager: CLLocationManager, didVisit visit: CLVisit) This did not work during my testing. It was only successfully triggered when starting from a distant location and arriving at the target point. It would be helpful to know the exact conditions, such as how long a user must stay at a location for it to be considered a visit. Are there any specific thresholds (e.g., minimum duration, distance moved) that determine when this method is triggered?

iPad widget bug
Widgets on the widget is not responding to the touch properly. This issue is also affecting within the home screen widget in a way that the widget switches to light mode by itself even though I am in dark mode. Additionally, lock screen does not to respond once the lock screen widget has been edited. Is anyone else having this issue?

Best way to share subscriptions between iOS and watchOS apps
I'm working on a watchOS app that has an iOS counterpart. There will be a subscription required to unlock functionality and I would like the user to be able to make the purchase on either the iPhone or the watch and have both apps unlock. The first link below says that StoreKit 2's Transaction.currentEntitlements will not work in this case like it does with extensions. The second link says it might work but doesn't in the sandbox. What is the best way to make this work? Will it just work in the App Store? Should I use WCSession to send the purchase information from one platform to the other and store it in the keychain? Something else? Via https://www.revenuecat.com/blog/engineering/ios-in-app-subscription-tutorial-with-storekit-2-and-swift/ "Transaction.currentEntitlements can be used in extensions the same way it was used in the previous steps. This works for extensions like Widgets and Intents. However, an iOS app with a companion watchOS app will not work even though Transaction.currentEntitlements can be executed in it. A companion watch app does not stay updated with the same transaction history as its iOS app because they are separate platforms." Via https://developer.apple.com/forums/thread/739963 "In TestFlight I was able to confirm that the Watch app and IOS app share in-app purchases. It seems the problems confirming this with Storekit and Sandbox are limits of the testing environments."

repeat subscription
After the user initiates the subscription payment, the SDK returns an error type: user cancels. When the user initiates the payment again, Apple will deduct the payment twice and successfully deduct the previously cancelled SKU. This is a recent occurrence with a large amount of data, and the app has not been upgraded in any way. We need to seek help. Thank you

Location Permission Management for Parental Control Apps with Screen Time Authorization
Apple Feedback Ticket: FB16804936 Background We develop a parental control application called Adora Kids (https://apps.apple.com/us/app/adora-kids/id6443787669) that requires "Location Always" permission to function properly. Our app has Screen Time authorization and provides monitoring services for parents. Issue We are experiencing a recurring problem where child users receive the system notification "Adora accessed your location in the background" every few days. This frequently results in children disabling location permissions, which prevents our app from functioning as intended. Current Approach and Limitations We have explored using Content & Privacy Restrictions for Location Services as a potential solution, but have encountered two significant limitations: These restrictions cannot be accessed programmatically via the ManagedSettings framework (unlike AppStoreSettings and other restrictions). The current implementation is "all-or-nothing" - enabling location restrictions blocks permission changes for ALL apps on the device, preventing children from granting legitimate location access to other applications. Questions Is there a way to programmatically access and manage Content & Privacy Restrictions for Location Services through the ManagedSettings framework that we might have overlooked? Are there any recommended approaches for apps with Screen Time authorization to prevent users from changing specific permissions (particularly location) while still allowing them to manage permissions for other apps? Does Apple have plans to implement app-specific permission locking for apps with Screen Time authorization in future iOS releases? Are there any alternative approaches or workarounds that other developers have successfully implemented for this use case? Any guidance from the developer community or Apple engineers would be greatly appreciated. This is a critical functionality issue affecting the reliability of our parental control service. Thank you in advance for your assistance.

The Map() of IOBufferMemoryDescriptor failure and cause the DriverKit Start() repeat
Hello Everyone, I am trying to develop a DriverKit for RAID system, using PCIDriverKit & SCSIControllerDriverKit framework. The driver can detect the Vendor ID and Device ID. But before communicating to the RAID system, I would like to simulate a virtual Volume using a memory block to talk with macOS. In the UserInitializeController(), I allocated a 512K memory for a IOBufferMemoryDescriptor* volumeBuffer, but fail to use Map() to map memory for volumeBuffer. result = ivars->volumeBuffer->Map( 0, // Options: Use default 0, // Offset: Start of the buffer ivars->volumeSize, // Length: Must not exceed buffer size 0, // Flags: Use default nullptr, // Address space: Default address space &mappedAddress // Output parameter ); Log("Memory mapped completed at address: 0x%llx", mappedAddress); // this line never run The Log for Map completed never run, just restart to run the Start() and makes this Driver re-run again and again, in the end, the driver eat out macOS's memory and system halt. Are the parameters for Map() error? or I should not put this code in UserInitializeController()? Any help is appreciated! Thanks in advance. Charles

Is the Time Sensitive Notification entitlement needed for visionOS?
I noticed the time sensitive entitlement says it's only for iOS and macOS. But without the entitlement, the time sensitive toggle doesn't show in my app's notification settings on visionOS. When I archive my visionOS app for App Store Connect, the entitlement seems to be taken out as it doesn't show in my entitlement list for the build in App Store Connect. I'm confused at this point if the entitlement is really necessary, since it seems to be needed to debug on the simulator at least. I don't have a physical device to test it on unfortunately.

Is it work startMonitoring from DeviceActivityMonitorExtension's eventDidReachThreshold function?
I want to monitor again from the bellow function of DeviceActivityMonitorExtension. I have the function of startMonitoring like this. override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { super.eventDidReachThreshold(event, activity: activity) startMonitoring() } public func startMonitoring() { let startTime = DateComponents(hour: 0, minute: 0, second: 0) let endTime = DateComponents(hour: 23, minute: 59, second: 59)//DateComponents(hour: 11, minute: 0, second: 0)// let schedule = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let selection: FamilyActivitySelection = savedSelection() ?? FamilyActivitySelection() let center = DeviceActivityCenter() let selections = self.savedSelection() ?? FamilyActivitySelection() let applications = selections.applicationTokens let categories = selections.categoryTokens let webCategories = selections.webDomainTokens let store = ManagedSettingsStore() store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set()) store.shield.applications = applications store.shield.webDomains = webCategories let scheduleHard = DeviceActivitySchedule( intervalStart: startTime,//DateComponents(hour: 0, minute: 0, second: 0), intervalEnd: endTime, repeats: true //warningTime: DateComponents(minute:1) ) let event = DeviceActivityEvent( applications: selection.applicationTokens, categories: selection.categoryTokens, webDomains: selection.webDomainTokens, threshold: DateComponents(minute: 0)//timeLimitToUseApp i.e for 15 mins ) do { try center.startMonitoring( .weekend, during: scheduleHard, events: [ .weekend: event, ] ) print("ScreenTime Monitoring Started") } catch let error { print(error.localizedDescription) } } Please provide us with a solution about starting monitoring from DeviceActivityMonitoringExtension's eventDidReachThreshold function or if there is any other way.

Background App wake up when Live Activity Offline Push Arrived not reliable
we have three problem when using the push notification on Live Activity. 1. What is the specific callback strategy for the activityUpdates property in ActivityKit? We found that in actual user scenarios, there is a probability that we may not receive callbacks. From the community experience, there are some resource optimization strategies that do not perform callbacks. From this perspective, the explanation is kind of vague. Is there any clear feedback to understand why callbacks are performed/not performed? 2.what is the specific description of the wake-up strategy, when background app receive Live Activity offline start Push? From community experience, we can see that the system may wake up for a duration of 0-30s due to resource optimization strategies, or not wake up/not deal with it. Is there an official description of the wake-up strategy? or we also have to follow this description: Wake up of apps using content-available pushes are heavily throttled. You can expect 1-2 wakeup per hour as a best case scenario in the hands of your users. so this cannot be assumed to be a reliable wake-up on demand mechanism for an app. 3 How can we determine user have selected (allow or always allow) of the Live Activity permission? When we use real-time activity offline push, there are two system prompts in iOS: the first prompt : allow and disallow real-time activity the second prompt : always allow and disallow Is there an interface that can directly determine which permission the user has chosen (allow/always allow)? (By the way, we can get disallow status). At present, we haven't seen any interface in the official documentation/interface that can determine (allow/always allow). The difference here will affect the generation of Update Token. Without Update Token, we can not update our activity instance.

CloudKit is not synchronizing with coredata for relationships
In core-data I have a contact and location entity. I have one-to-many relationship from contact to locations and one-to-one from location to contact. I create contact in a seperate view and save it. Later I create a location, fetch the created contact, and save it while specifying the relationship between location and contact contact and test if it actually did it and it works. viewContext.perform { do { // Set relationship using the generated accessor method currentContact.addToLocations(location) try viewContext.save() print("Saved successfully. Locations count:", currentContact.locations?.count ?? 0) if let locs = currentContact.locations { print("📍 Contact has \(locs.count) locations.") for loc in locs { print("➡️ Location: \(String(describing: (loc as AnyObject).locationName ?? "Unnamed"))") } } } catch { print("Failed to save location: \(error.localizedDescription)") } } In my NSManagedObject class properties I have this : for Contact: @NSManaged public var locations: NSSet? for Location: @NSManaged public var contact: Contact? in my persistenceController I have: for desc in [publicStore, privateStore] { desc.setOption(true as NSNumber, forKey: NSPersistentStoreRemoteChangeNotificationPostOptionKey) desc.setOption(true as NSNumber, forKey: NSPersistentHistoryTrackingKey) desc.setOption(true as NSNumber, forKey: NSMigratePersistentStoresAutomaticallyOption) desc.setOption(true as NSNumber, forKey: NSInferMappingModelAutomaticallyOption) desc.setOption(true as NSNumber, forKey: "CKSyncCoreDataDebug") // Optional: Debug sync // Add these critical options for relationship sync desc.setOption(true as NSNumber, forKey: "NSPersistentStoreCloudKitEnforceRecordExistsKey") desc.setOption(true as NSNumber, forKey: "NSPersistentStoreCloudKitMaintainReferentialIntegrityKey") // Add this specific option to force schema update desc.setOption(true as NSNumber, forKey: "NSPersistentStoreRemoteStoreUseCloudKitSchemaKey") } When synchronization happens on CloudKit side, it creates CKRecords: CD_Contact and CD_Location. However for CD_Location it creates the relationship CD_contact as a string and references the CD_Contact. This I thought should have come as REFERENCE On the CD_Contact there is no CD_locations field at all. I do see the relationships being printed on coredata side but it does not come as REFERENCE on cloudkit. Spent over a day on this. Is this normal, what am I doing wrong here? Can someone advise?

Understanding Also-Ran Connections
Every now and again folks notice that Network framework seems to create an unexpected number of connections on the wire. This post explains why that happens and what you should do about it. If you have questions or comments, put them in a new thread here on the forums. Use the App & System Services > Networking topic area and the Network tag. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Understanding Also-Ran Connections Network framework implements the Happy Eyeballs algorithm. That might create more on-the-wire connections than you expect. There are two common places where folks notice this: When looking at a packet trace When implementing a listener Imagine that you’ve implemented a TCP server using NWListener and you connect to it from a client using NWConnection. In many situations there are multiple network paths between the client and the server. For example, on a local network there’s always at least two paths: the link-local IPv6 path and either an infrastructure IPv4 path or the link-local IPv4 path. When you start your NWConnection, Network framework’s Happy Eyeballs algorithm might [1] start a TCP connection for each of these paths. It then races those connections. The one that connects first is the ‘winner’, and Network framework uses that connection for your traffic. Once it has a winner, the other connections, the also-ran connections, are redundant, and Network framework just closes them. You can observe this behaviour on the client side by looking in the system log. Many Network framework log entries (subsystem com.apple.network) contain a connection identifier. For example C8 is the eighth connection started by this process. Each connection may have child connections (C8.1, C8.2, …) and grandchild connections (C8.1.1, C8.1.2, …), and so on. You’ll see state transitions for these child connections occurring in parallel. For example, the following log entries show that C8 is racing the connection of two grandchild connections, C8.1.1 and C8.1.2: type: debug time: 12:22:26.825331+0100 process: TestAlsoRanConnections subsystem: com.apple.network category: connection message: nw_socket_connect [C8.1.1:1] Calling connectx(…) type: debug time: 12:22:26.964150+0100 process: TestAlsoRanConnections subsystem: com.apple.network category: connection message: nw_socket_connect [C8.1.2:1] Calling connectx(…) Note For more information about accessing the system log, see Your Friend the System Log. You also see this on the server side, but in this case each connection is visible to your code. When you connect from the client, Network framework calls your listener’s new connection handler with multiple connections. One of those is the winning connection and you’ll receive traffic on it. The others are the also-ran connections, and they close promptly. IMPORTANT Depending on network conditions there may be no also-ran connections. Or there may be lots of them. If you want to test the also-ran connection case, use Network Link Conditioner to add a bunch of delay to your packets. You don’t need to write special code to handle also-ran connections. From the perspective of your listener, these are simply connections that open and then immediately close. There’s no difference between an also-ran connection and, say, a connection from a client that immediately crashes. Or a connection generated by someone doing a port scan. Your server must be resilient to such things. However, the presence of these also-ran connections can be confusing, especially if you’re just getting started with Network framework, and hence this post. [1] This is “might” because the exact behaviour depends on network conditions. More on that below.

How is Security Delay still so broken?
I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together. Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!
