Hi there, I'm facing an issue when disconnecting CarPlay that the navigation session seems to be in some weird state where it is not properly finished. So when I reconnect CarPlay the "Metadata in instrument cluster or HUD" does not update anymore until I start another navigation session and stop that one. You can see that the instruction to the left on this screen recording is not updating anymore after a reconnect. https://www.youtube.com/watch?v=sncxyJULjQk I have a modified the CostalRoad sample app to add support for the HUD cluster and to auto start a navigation simulation when CarPlay connects. https://github.com/g4rb4g3/CoastalRoads Can anyone tell me what I have to do when CarPlay disconnect so I can start a new navigation session on reconnect that has a working HUD cluster? Fun fact is that Apple Maps handles this quite nice (https://www.youtube.com/watch?v=OpJEIyGcwdo), it somehow manages to finish the navigation session and brings up the HUD cluster just fine on reconnect. I wonder how I can achieve the same, anyone having an idea on that?

I have been receiving beta software from the iPad App Store, despite not being enrolled in a beta program. Additionally, I do not have TestFlight or the Feedback app installed on my device. There are no certificates or profiles displayed either. I am using the App Store app that comes preinstalled on my device (note that I am not located in Europe). My iPad has been experiencing significant bugs, including numerous screen glitches and periods of sluggishness. Furthermore, numerous applications have crashed frequently. I was able to confirm that I was receiving beta software because the crash reports include beta identifier numbers. According to Apple documentation regarding analytic reports, a beta identifier will only be visible for beta applications. anyone know what could be going on or how to fix this?

Document based SwiftData apps do not autosave changes to the ModelContext at all. This issue has been around since the first release of this SwiftData feature. In fact, the Apple WWDC sample project (https://developer.apple.com/documentation/swiftui/building-a-document-based-app-using-swiftdata) does not persist any data in its current state, unless one inserts modelContext.save() calls after every data change. I have reported this under the feedback ID FB16503154, as it seemed to me that there is no feedback report about the fundamental issue yet.

Hi everyone, We operate an online game where all in-app assets are stored server-side and require a logged-in account (no device binding). I’d like guidance on four areas: Do we really need deviceVerification / deviceVerificationNonce? – Because every purchase is tied to an account and we enforce a global transactionId UNIQUE constraint, replay or cross-account reuse appears infeasible. Under these conditions, is omitting device verification acceptable, or are there situations where Apple still recommends it? Permanent rate-limit increase for the App Store Server API – During anniversary events we saw bursts of ~18 000 requests per hour, breaching the current hourly cap on the App Store Server API (verifyTransaction, getNotificationHistory, etc.). Is there a formal process to request a long-term rate-limit expansion (or an alternative tier) from Apple? When is an App Store Server API call required for a StoreKit 2 jwsRepresentation? Docs say “call the API if you’re unsure,” but there’s no clear cut-off. Because we fully validate the JWS signature plus the entire certificate chain (including CRL/OCSP checks) on our server, local cryptographic validation seems sufficient for consumables. For subscriptions we still plan to hit the API to fetch the latest status. Does this separation match Apple’s best practice? If Apple does recommend hitting the API for consumables as well, we’d like a concrete rule of thumb—e.g. “if the item price is USD 50 or higher, always use the API.” Is establishing such thresholds consistent with Apple’s intent? Refund-risk reduction from Send Consumption Info – Adapty reports a 40–60 % refund-rate drop for subscriptions when using Send Consumption Info (blog reference). Can we expect similar reduction for consumable IAP in social/online games? Any real-world results would be helpful. Thanks in advance for any guidance!

We're in the process of migrating our app to the Swift 6 language mode. I have hit a road block that I cannot wrap my head around, and it concerns Core Data and how we work with NSManagedObject instances. Greatly simplied, our Core Data stack looks like this: class CoreDataStack { private let persistentContainer: NSPersistentContainer var viewContext: NSManagedObjectContext { persistentContainer.viewContext } } For accessing the database, we provide Controller classes such as e.g. class PersonController { private let coreDataStack: CoreDataStack func fetchPerson(byName name: String) async throws -> Person? { try await coreDataStack.viewContext.perform { let fetchRequest = NSFetchRequest<Person>() fetchRequest.predicate = NSPredicate(format: "name == %@", name) return try fetchRequest.execute().first } } } Our view controllers use such controllers to fetch objects and populate their UI with it: class MyViewController: UIViewController { private let chatController: PersonController private let ageLabel: UILabel func populateAgeLabel(name: String) { Task { let person = try? await chatController.fetchPerson(byName: name) ageLabel.text = "\(person?.age ?? 0)" } } } This works very well, and there are no concurrency problems since the managed objects are fetched from the view context and accessed only in the main thread. When turning on Swift 6 language mode, however, the compiler complains about the line calling the controller method: Non-sendable result type 'Person?' cannot be sent from nonisolated context in call to instance method 'fetchPerson(byName:)' Ok, fair enough, NSManagedObject is not Sendable. No biggie, just add @MainActor to the controller method, so it can be called from view controllers which are also main actor. However, now the compiler shows the same error at the controller method calling viewContext.perform: Non-sendable result type 'Person?' cannot be sent from nonisolated context in call to instance method 'perform(schedule:_:)' And now I'm stumped. Does this mean NSManageObject instances cannot even be returned from calls to NSManagedObjectContext.perform? Ever? Even though in this case, @MainActor matches the context's actor isolation (since it's the view context)? Of course, in this simple example the controller method could just return the age directly, and more complex scenarios could return Sendable data structures that are instantiated inside the perform closure. But is that really the only legal solution? That would mean a huge refactoring challenge for our app, since we use NSManageObject instances fetched from the view context everywhere. That's what the view context is for, right? tl;dr: is it possible to return NSManagedObject instances fetched from the view context with Swift 6 strict concurrency enabled, and if so how?

I have a document based SwiftData app in which I would like to implement a persistent cache. For obvious reasons, I would not like to store the contents of the cache in the documents themselves, but in my app's data directory. Is a use case, in which a document based SwiftData app uses not only the ModelContainers from the currently open files, but also a ModelContainer writing a database file in the app's documents directory (for cache, settings, etc.) supported? If yes, how can you inject two different ModelContexts, one tied to the currently open file and one tied to the local database, into a SwiftUI view?

Hi everyone, I'm working on an app for parents and kids where parents can define screen time goals or restrict usage of certain app categories (like social media or games). If the kid follows those rules—for example, by using their device less or avoiding restricted categories—they would earn points or rewards in the app. I’ve been exploring if the Apple Screen Time API allows developers to access this kind of data (like total screen time, app usage by category, etc.) so that I can track the kid’s behavior and reward them accordingly. Is it possible to programmatically access this data and implement such a reward system within my app? If so, what’s the best way to get started or which APIs should I look into? Thanks in advance for your help!

Hi all, I am using SwiftData and cloudkit and I am having an extremely persistent bug. I am building an education section on a app that's populated with lessons via a local JSON file. I don't need this lesson data to sync to cloudkit as the lessons are static, just need them imported into swiftdata so I've tried to use the modelcontainer like this: static func createSharedModelContainer() -> ModelContainer { // --- Define Model Groups --- let localOnlyModels: [any PersistentModel.Type] = [ Lesson.self, MiniLesson.self, Quiz.self, Question.self ] let cloudKitSyncModels: [any PersistentModel.Type] = [ User.self, DailyTip.self, UserSubscription.self, UserEducationProgress.self // User progress syncs ] However, what happens is that I still get Lesson and MiniLesson record types on cloudkit and for some reason as well, whenever I update the data models or delete and reinstall the app on simulator, the lessons duplicate (what seems to happen is that a set of lessons comes from the JSON file as it should), and then 1-2 seconds later, an older set of lessons gets synced from cloudkit. I can delete the old set of lessons if I just delete the lessons and mini lessons record types, but if I update the data model again, this error reccurrs. Sorry, I don't know if I managed to explain this well but essentially I just want to stop the lessons and minilessons from being uploaded to cloudkit as I think this will fix the problem. Am I doing something wrong with the code?

I am trying to get a pass reader certified through the mFi / WPC certification process. The problem I have is that the Certifier app will not allow testing results to be submitted due to some missing information. I need support to discuss the missing information, but I have received no replies from the email provided for WPC Certification Representative. Does anyone here know how to get support for the WPC Certification process?

Hello everyone, I’m running an Objective-C–based hybrid (native + web) shopping application and encountering a recurring issue on devices running iOS 18.1.1: When the app launches, it only shows a white screen with the native frame visible—no web content loads. Restarting or reinstalling the app doesn’t help. In one instance, toggling Airplane Mode on and off brought the app back to normal, but this workaround isn’t consistent. There are no crash logs, so we can’t determine if it’s caused by a network error, cache conflict, or an OS-level bug. So far, we have only seen this issue on iOS 18.1.1 devices. Because our app is a shopping platform, this significantly impacts users. Questions: Could this be related to a known bug or limitation in iOS 18.1.1? Are there recommended diagnostic steps or workarounds for a hybrid app that shows a white screen without generating crash logs? Which additional details (e.g., system logs, network traces, device configurations) might help isolate the cause? Any insights or suggestions would be greatly appreciated. Thank you in advance!

Hi all, I’m testing Subscription in my Flutter app on a real iOS device (iPhone 16 Pro with iOS 18) via TestFlight. I’ve set everything up as required, but I still get this error: flutter: Found products: [] If everything works perfectly when StoreKit configuration is used in Xcode, but not via TestFlight. All my Subscriptions are approved with the same ID.

Issue Description I am experiencing persistent 401 Unauthorized errors when attempting to access the App Store Server API using JWT authentication. Despite following Apple's documentation and regenerating keys, I am unable to successfully authenticate. Implementation Details I'm implementing JWT authentication for the App Store Server API to retrieve transaction information from the following endpoint: https://api.storekit.itunes.apple.com/inApps/v1/transactions/{transactionID} My JWT generation code (in PHP/Laravel) follows Apple's documentation: php$kid = '6W6H649LJ4'; $header = [ "alg" => "ES256", "kid" => $kid, "typ" => "JWT" ]; $iss = 'b8d99de7-b43b-4cbb-aada-546ec784e249'; // App Store Connect API Key Issuer ID $bid = 'com.gitiho.learnCourse'; // Bundle ID $payload = [ "iss" => $iss, "iat" => time(), "exp" => time() + 3600, "aud" => "appstoreconnect-v1", "bid" => $bid ]; $pathFileAuthKeyP8 = "AuthKey_6W6H649LJ4.p8"; $contentFileAuthKey = \File::get(base_path($pathFileAuthKeyP8)); $alg = "ES256"; $jwt = \Firebase\JWT\JWT::encode($payload, $contentFileAuthKey, $alg, null, $header); Steps Taken to Troubleshoot Verified that the Issuer ID is correct and in UUID format Confirmed that the Key ID matches the private key filename Regenerated the key with proper App Store Server API permissions Ensured the private key file is properly formatted with correct headers and footers Verified that the JWT is being properly encoded using the ES256 algorithm Confirmed the bundle ID is correct for our application Checked that the API endpoint URL is correct Additional Information This implementation previously worked correctly We started experiencing 401 errors recently without changing our implementation We are using the Firebase JWT library for PHP to encode the JWT Request Could you please help identify what might be causing these authentication failures? Is there any recent change in the authentication requirements or endpoint URLs that might be affecting our integration? Thanks for support me.

Are the network relays introduced in 2023 and https://developer.apple.com/videos/play/wwdc2023/10002/ the same thing as the Private Relay introduced in 2021? https://developer.apple.com/videos/play/wwdc2021/10096/ We are considering verifying the relay function, but we are not sure whether they are the same function or different functions. https://developer.apple.com/documentation/devicemanagement/relay?language=objc

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.

Is there any way to use AccessorySetupKit in the background to discover BLE devices?

Hello everyone! We are observing a significant number of failures in the fetch of the products with StoreKit1, meaning that in a completely random way, some product identifiers are considered invalid in the response that we receive from Apple, and after some minutes these products are considered once again valid. The issue started on Thursday 04/24 around 12.00 am (UTC + 02.00) and from our dashboard we can clearly see the trend of these failures has some spikes at precise times. I am attaching a view that we use for monitoring purposes showing this trend, considering the data of this week. We are noticing this problem on multiple developer accounts and on multiple apps, which is leading us to think it could be an issue in the Apple backend processing the request. In our case, the apps are not launched correctly until all the products are fetched, and therefore the impact of this problem is very high. Is anyone experiencing something similar or do you have logs which allows you to identify such issues? The issue happens only in production, while in debug and TestFlight environment everything works well. Thank you for your support

Note: I have had issues with CMAltimeter since whats seems to have been a major undocumented modification since iOS 17.4. So I'm using the CMAltimeter absolute locations delivery. Sometimes, the altimeter seems to be in an uncalibrated mode and therefore, no altitude delivery happens. Is there a way to be inform of such state? Currently, it just doesn't work and I can't inform the user about this. They just think the app is broken What message should I give to the users to accelerate the calibration such that the CMAltimeter will work again? Also, users have reported that the CMAltimeter can temporarily stop delivering altitude updates, even though it should. So I guess my question resumes to this: Whats the best practice to handle an uncalibrated CMAltimeter? Thanks!

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!

Hello developers! I am working with a team of North Carolina State University researchers to create an app or program that can retrieve real-time traffic events, such as hazards, road closures, and road construction alerts, in a similar manner to the Apple Maps app, but with the added functionality of collecting them over a historical period given a start and end date. I'm looking through the MapKit documentation, but there doesn't appear to be any functions exposing granular traffic data (i.e. road hazards), just travel times and level of congestion. Could anyone point me in the right direction? Is what I'm looking to do even possible using just Apple data?

Hello, I am building a pretty large database (~40MB) to be used in my SwiftData iOS app as read-only. While inserting and updating the data, I noticed a substantial increase in size (+ ~10MB). A little digging pointed to ACHANGE and ATRANSACTION tables that apparently are dealing with Persistent History Tracking. While I do appreciate the benefits of that, I prefer to save space. Could you please point me in the right direction?
