Touchscreen gestures in CarPlay aren't recognized in the app
Touchscreen gestures in CarPlay aren't recognized in the app (delegate CPMapTemplateDelegate functions aren't called). Tried also in the Coastal Roads demo app to add test functions to check that pan functions are called - the same: func mapTemplateDidBeginPanGesture(_ mapTemplate: CPMapTemplate) { MemoryLogger.shared.appendEvent("Did begin pan gesture.") } func mapTemplate(_ mapTemplate: CPMapTemplate, panBeganWith direction: CPMapTemplate.PanDirection) { MemoryLogger.shared.appendEvent("Did begin pan gesture with direction \(direction.rawValue).") } Note: buttons (on carplay app) are working when pressing on them. Also, the desktop of carplay can be panned (by swipe gesture). Using Xcode 14.3, MacBook pro M1

Don’t Try to Get the Device’s IP Address
For important background information, read Extra-ordinary Networking before reading this. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Don’t Try to Get the Device’s IP Address I regularly see questions like: How do I find the IP address of the device? How do I find the IP address of the Wi-Fi interface? How do I identify the Wi-Fi interface? I also see a lot of really bad answers to these questions. That’s understandable, because the questions themselves don’t make sense. Networking on Apple platforms is complicated and many of the things that are ‘obviously’ true are, in fact, not true at all. For example: There’s no single IP address that represents the device, or an interface. A device can have 0 or more interfaces, each of which can have 0 or more IP addresses, each of which can be IPv4 and IPv6. A device can have multiple interfaces of a given type. It’s common for iPhones to have multiple WWAN interfaces, for example. It’s not possible to give a simple answer to any of these questions, because the correct answer depends on the context. Why do you need this particular information? What are you planning to do with it? This post describes the scenarios I most commonly encounter, with my advice on how to handle each scenario. IMPORTANT BSD interface names, like en0, are not considered API. There’s no guarantee, for example, that an iPhone’s Wi-Fi interface is en0. If you write code that relies on a hard-coded interface name, it will fail in some situations. Service Discovery Some folks want to identify the Wi-Fi interface so that they can run a custom service discovery protocol over it. Before you do that, I strongly recommend that you look at Bonjour. This has a bunch of advantages: It’s an industry standard [1]. It’s going to be more efficient on the ‘wire’. You don’t have to implement it yourself, you can just call an API [2]. For information about the APIs available, see TN3151 Choosing the right networking API. If you must implement your own service discovery protocol, don’t think in terms of finding the Wi-Fi interface. Rather, write your code to work with all Wi-Fi interfaces, or perhaps even all Ethernet-like interfaces. That’s what Apple’s Bonjour implementation does, and it means that things will work in odd situations [3]. To find all Wi-Fi interfaces, get the interface list and filter it for ones with the Wi-Fi functional type. To find all broadcast-capable interfaces, get the interface list and filter it for interfaces with the IFF_BROADCAST flag set. If the service you’re trying to discover only supports IPv4, filter out any IPv6-only interfaces. For advice on how to do this, see Interface List and Network Interface Type in Network Interface APIs. When working with multiple interfaces, it’s generally a good idea to create a socket per interface and then bind that socket to the interface. That ensures that, when you send a packet, it’ll definitely go out the interface you expect. For more information on how to implement broadcasts correctly, see Broadcasts and Multicasts, Hints and Tips. [1] Bonjour is an Apple term for: RFC 3927 Dynamic Configuration of IPv4 Link-Local Addresses RFC 6762 Multicast DNS RFC 6763 DNS-Based Service Discovery [2] That’s true even on non-Apple platforms. It’s even true on most embedded platforms. If you’re talking to a Wi-Fi accessory, see Working with a Wi-Fi Accessory. [3] Even if the service you’re trying to discover can only be found on Wi-Fi, it’s possible for a user to have their iPhone on an Ethernet that’s bridged to a Wi-Fi. Why on earth would they do that? Well, security, of course. Some organisations forbid their staff from using Wi-Fi. Logging and Diagnostics Some folks want to log the IP address of the Wi-Fi interface, or the WWAN, or both for diagnostic purposes. This is quite feasible, with the only caveat being there may be multiple interfaces of each type. To find all interfaces of a particular type, get the interface list and filter it for interfaces with that functional type. See Interface List and Network Interface Type in Network Interface APIs. Interface for an Outgoing Connection There are situations where you need to get the interface used by a particular connection. A classic example of that is FTP. When you set up a transfer in FTP, you start with a control connection to the FTP server. You then open a listener and send its IP address and port to the FTP server over your control connection. What IP address should you use? There’s an easy answer here: Use the local IP address for the control connection. That’s the one that the server is most likely to be able to connect to. To get the local address of a connection: In Network framework, first get the currentPath property and then get its localEndpoint property. In BSD Sockets, use getsockname. See its man page for details. Now, this isn’t a particularly realistic example. Most folks don’t use FTP these days [1] but, even if they do, they use FTP passive mode, which avoids the need for this technique. However, this sort of thing still does come up in practice. I recently encountered two different variants of the same problem: One developer was implementing VoIP software and needed to pass the devices IP address to their VoIP stack. The best IP address to use was the local IP address of their control connection to the VoIP server. A different developer was upgrading the firmware of an accessory. They do this by starting a server within their app and sending a command to the accessory to download the firmware from that server. Again, the best IP address to use is the local address of the control connection. [1] See the discussion in TN3151 Choosing the right networking API. Listening for Connections If you’re listening for incoming network connections, you don’t need to bind to a specific address. Rather, listen on all local addresses. In Network framework, this is the default for NWListener. In BSD Sockets, set the address to INADDR_ANY (IPv4) or in6addr_any (IPv6). If you only want to listen on a specific interface, don’t try to bind to that interface’s IP address. If you do that, things will go wrong if the interface’s IP address changes. Rather, bind to the interface itself: In Network framework, set either the requiredInterfaceType property or the requiredInterface property on the NWParameters you use to create your NWListener. In BSD Sockets, set the IP_BOUND_IF (IPv4) or IPV6_BOUND_IF (IPv6) socket option. How do you work out what interface to use? The standard technique is to get the interface list and filter it for interfaces with the desired functional type. See Interface List and Network Interface Type in Network Interface APIs. Remember that their may be multiple interfaces of a given type. If you’re using BSD Sockets, where you can only bind to a single interface, you’ll need to create multiple listeners, one for each interface. Listener UI Some apps have an embedded network server and they want to populate a UI with information on how to connect to that server. This is a surprisingly tricky task to do correctly. For the details, see Showing Connection Information for a Local Server. Outgoing Connections In some situations you might want to force an outgoing connection to run over a specific interface. There are four common cases here: Set the local address of a connection [1]. Force a connection to run over a specific interface. Force a connection to run over a type of interface. Force a connection to run over an interface with specific characteristics. For example, you want to download some large resource without exhausting the user’s cellular data allowance. The last case should be the most common — see the Constraints section of Network Interface Techniques — but all four are useful in specific circumstances. The following sections explain how to tackle these tasks in the most common networking APIs. [1] This implicitly forces the connection to use the interface with that address. For an explanation as to why, see the discussion of scoped routing in Network Interface Techniques. Network Framework Network framework has good support for all of these cases. Set one or more of the following properties on the NWParameters object you use to create your NWConnection: requiredLocalEndpoint property requiredInterface property prohibitedInterfaces property requiredInterfaceType property prohibitedInterfaceTypes property prohibitConstrainedPaths property prohibitExpensivePaths property Foundation URL Loading System URLSession has fewer options than Network framework but they work in a similar way: Set one or more of the following properties on the URLSessionConfiguration object you use to create your session: allowsCellularAccess property allowsConstrainedNetworkAccess property allowsExpensiveNetworkAccess property Note While these session configuration properties are also available on URLRequest, it’s better to configure this on the session. There’s no option that forces a connection to run over a specific interface. In most cases you don’t need this — it’s better to use the allowsConstrainedNetworkAccess and allowsExpensiveNetworkAccess properties — but there are some situations where that’s necessary. For advice on this front, see Running an HTTP Request over WWAN. BSD Sockets BSD Sockets has very few options in this space. One thing that’s easy and obvious is setting the local address of a connection: Do that by passing the address to bind. Alternatively, to force a connection to run over a specific interface, set the IP_BOUND_IF (IPv4) or IPV6_BOUND_IF (IPv6) socket options.

Handling Data Download Backpressure in URLSession
I am developing an application that processes a video file stored on a server. I use URLSessionDataTask with a delegate handler to download the file. It is not necessary to download the entire file at once. Instead, I can load small chunks of the file as needed. This approach helps minimize memory consumption. I am trying to design a network layer that supports this behavior. Ideally, I would like to have an interface similar to: func readMoreData(length: Int) async throws -> Data Problems I Encountered: It seems that URLSessionDataTask does not allow controlling how many bytes will be downloaded. It always downloads the entire request. If I call suspend on URLSessionDataTask, the network activity does not stop, and the file keeps downloading. If I upgrade the dataTask to a StreamTask, the file still downloads, though reading bytes can be done through the StreamTask API. I would prefer behavior similar to AsyncHTTPClient (a Swift Server library) or Network Framework. These frameworks allow controlling the number of bytes downloaded at a time. Unfortunately, they do not fit the specific requirements of my project. Am I correct in understanding that controlling the download process is not possible with URLSessionDataTask? As a possible solution, I am considering using HTTP Range Requests, though this would increase the number of additional server requests, which I would like to avoid.

Possible to access CoreData/Persistent storage from DeviceActivityReportExtension?
This is more a general question of whether it is possible to share persistent/coredata from the main app to Screentime-related extensions such as DeviceActivityReportExtension. I've set my code up (e.g., App Groups, files to different targets, using nspersistentcontainer with app group url, etc.) in a way that it builds, and the extension seems to recognize my CoreData schema (able to query using fetchrequest). But the data returned is always null. So i'm wondering if it is even possible to READ app data from the extension. I understand it is not possible to write or pass data from the extension back to the app. I've also been able to read data that was saved in main app from UserDefaults in my extension.

CKShare Fails with quotaExceeded Error on Family iCloud Plan
Hello, When attempting to create a CKShare on a personal device linked to a Family iCloud plan (non-primary account holder), the operation fails with a quotaExceeded error. This occurs with the Family plan having 1.5TB available storage space. This is also causing a data loss for the object(s) that were attempted to be shared. Details Account Type: Family iCloud Plan (2TB total storage) Current Family Usage: 399GB iCloud Account Usage: 70 GB Steps to Reproduce: Have an iCloud account with storage over the 5GB free space limit. Be on a part of a iCloud Family Plan as the non-primary account holder. Have storage space available in the Family Plan Attempt to start a CloudKit Share/Collaboration on the device. Observe that the CKShare creation fails with a quotaExceeded error. Expected Behavior: The CKShare should be successfully created, reflecting the total available storage of the Family plan. Observed Behavior: The CKShare fails to be created with quotaExceeded. Additional Testing On a test device using an iCloud account with no stored data, the CKShare was created successfully and shared without issue. Suspected Cause The CKShare functionality is verifying the personal storage allocation of the iCloud account and failing without checking total available storage provided by the Family plan.

HealthKit SDK Not Responding When Querying Step Data on iPhone 16 Pro Max
We have working code to fetch step data from HealthKit after requesting the necessary permissions. However, we’ve encountered an issue specific to one device, the iPhone 16 Pro Max. When querying the data, we do not receive a response, and the code enters an infinite loading state without completing the request. The user who is facing this issue has tried logging in on another device, and it works fine. On the problematic device (iPhone 16 Pro Max), the request does not complete. For reference, I’ve included the code below. Resolving this issue is crucial, so we would appreciate any guidance on what steps we can take to troubleshoot or resolve the problem on this specific device. Please note that the device has granted permission to access HealthKit data. static let healthStore = HKHealthStore() static func limitReadFromHealthKitBetweenDates(fromDate: Date, toDate: Date = Date(), completion: @escaping ([HKStatistics]) -> Void) { guard let stepsQuantityType = HKQuantityType.quantityType(forIdentifier: .stepCount) else { return } let ignoreUserEntered = HKQuery.predicateForObjects(withMetadataKey: HKMetadataKeyWasUserEntered, operatorType: .notEqualTo, value: true) let now = toDate var interval = DateComponents() interval.day = 1 var calendar = Calendar.current calendar.locale = Locale(identifier: "en_US_POSIX") var anchorComponents = calendar.dateComponents([.day, .month, .year], from: now) anchorComponents.hour = 0 let anchorDate = calendar.date(from: anchorComponents) ?? Date() let query = HKStatisticsCollectionQuery(quantityType: stepsQuantityType, quantitySamplePredicate: ignoreUserEntered, options: [.cumulativeSum], anchorDate: anchorDate, intervalComponents: interval) query.initialResultsHandler = { _, results, error in guard let results = results else { print("Error returned from resultHandler: \(String(describing: error?.localizedDescription))") return } print(results) var statisticsArray: [HKStatistics] = [] results.enumerateStatistics(from: fromDate, to: now) { statistics, _ in statisticsArray.append(statistics) if statistics.endDate.getddmmyyyyslashGMT == now.getddmmyyyyslashGMT { completion(statisticsArray) } } } healthStore.execute(query) } Please note that the code works on all devices except the problematic one. Could you please guide me on the next steps to resolve this issue?

I don't understand apple store server to server notification
Hello, I'am trying to validate a new app from apple. I have configured sandbox url and production url for server to server apple store notification. I have created subscriptions product id, but there are no validated yet by apple. When I upload my app to testflight, I can't test sandbox notification cause the product id are not available, on local xcode with storekit file I got my product Id but I don't receive notification. So my question is how can I test there thing. I have to produce fake product id ? I'm lock its very complex process, I don't understand. I tried to send my app like that for verification but the team told me to use receipt, but its deprecated and notification webhook is better for me. What is the good order, validate my subscription product ID then test ? what is the good steps. Apple seems to don't want validate my subscription product ID I'm lock..

Not able to log proc ID in controlFilter
I was trying to log the flow description using control filter and data filter. But when I am trying to log the proc ID in control filter, it is always 0, but in data filter, it logs some value. Same goes with the eproc ID. I want to use the flow description data in some other target so I will be sending the data using sockets and I cannot share data from data filter due to its restrictions and control filter isn't providing the proc ID. What should I do?

App Clip works in TestFlight but not elsewhere
My app is available in TestFlight but has been rejected in App Review with the review feedback that the app clip "just shows a blank screen". However, in the TestFlight app, the App Clip works as expected and brings up the clip. It also works correctly from Xcode testing. Any ideas on what the problem could be? It is using the default App Clip link (appclip.apple.com)

Launch URL
Hi I am developing a game app with Epic Unreal Engine. I am testing this as testFlight these days. My problem is “launch URL” what a function in Unreal Engine. This is a function that allows user to search the Internet with the entered URL. It worked well before. But not now. I don't know when it did start not working. It's like after the iPhone IOS update or the Xcode update. Mac sequoia 15.1.1 Xcode 16.2 ( Unreal Engine 5.4.4 ) IOS is 18.2. but It didn't work since the just previous version. Any advice can I get?

Clarification on offerIdentifier Behavior in TransactionPayload and Upgrade Scenarios
Hello everyone, I have some questions regarding the behavior of the offerIdentifier property in the TransactionPayload from App Store Server Notifications. When a user redeems an Offer Code, the offerIdentifier field is populated with the respective identifier. However, I am unsure how this field behaves in different scenarios, and I would appreciate any insights or clarification: Does the offerIdentifier persist throughout the subscription lifecycle (from the initial purchase to expiration)? Does it become null once the Offer Code benefits expire? Is it only present at the time of purchase and omitted in subsequent notifications? Additionally, I would like to understand the behavior of the offerIdentifier in the following scenario: A user purchases a lower-tier subscription using an Offer Code. Later, they upgrade to a higher-tier plan, causing the Offer Code benefits to effectively expire. What happens to the offerIdentifier in the transaction for the upgrade? Will it still appear in transactions after the upgrade, or will it be null? I couldn't find explicit details about these situations in the official documentation, so I hope someone here might have experience or knowledge to share. Thank you in advance for your help!

Push notification of server certificate updates for the service
Background: ① We initiate push notification requests by generating tokens using the p8 certificate. ② The lowest version of the server we use is Ubuntu 16.04, and the image is Alpine Linux 3.15. ③ Currently, the root certificate USERTrust_RSA_Certification_Authority.pem is default in the system and has the same MD5 value as the provided download file. The time for both is 2019. My questions: ① Which certificate should we download and add to the server's trust store, Root Certificates? ② Does the system we are using default include this certificate? ③ What operations are needed for this server certificate replacement?

What are causes of networkURLUnauthorized in a message filter extension
I'm getting ILMessageFilterError.networkURLUnauthorized returned in a message filter extension when calling deferQueryRequestToServer(). Googling for people who have had the same error, they didn't include the associated domain in the containing app. However I have added that. The server is set up at https://something.com:443, it has an apple association file located at https://something.com:443/.well-known/apple-app-site-association I have added associated domains to the app and the app extension of: messagefilter:something.com?mode=developer webcredentials:something.com?mode=developer Side question 1: are both needed or just the messagefilter? Side question 2: should the domain include the port :443? The server isn't publicly hosted hence I've appended ?mode=developer on the end as per the documentation. The extension's info.plist has ILMessageFilterExtensionNetworkURL added as something.com Question 3: Does this need the port adding too? With everything set up according to the documentation, apart from the questions above, what might be the cause of getting networkURLUnauthorized returned?
