I'm working with the Apple Watch's acceleration data and have referred to the document Identify the coordinate axes of the device. According to this document, the X-axis points to the right side of the watch, the Y-axis points towards the top side, and the Z-axis points towards the user. However, when I place the watch on a flat surface and move it horizontally to the right, I observe that the X-axis acceleration is negative. Similarly, when I move the watch vertically upwards, the Y-axis acceleration also shows a negative value. Is this expected behavior, or am I misunderstanding something about the coordinate system or acceleration readings?

I was trying to fetch inBytes and outBytes in content filter. Each time it is logging 0 as inByte and outByte in handleNewFlow flow description. How to get inByte and outByte of the flow?

Didn't get any response last time so reposting my query. I know procID is of no use in IOS but just for curiosity I am logging proc ID in control Filter and data Filter. 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?

In the documentation for a Message Filter Extension it states: If you have servers that can help your app extension determine how to handle a message, you must add the Associated Domains capability to your Xcode project and specify those domains. (https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering/creating_a_message_filter_app_extension) The words servers and domains are in the plural. If it's possible to specify multiple servers/domains for a Message Filter Extension then how is that done? There's no documentation nor reference for that. If multiple domains can be added to the info.plist then what is the iOS behavior in that case? Can the extension supply/change which domain is used at run time?

Am showing daily screen-time of a user in my app in Device Activity Report Extension. The only way to get that is to sum up all the activityDuration of apps/categories/domains. But it differs a lot from phone's settings screen-time, why? I have debugged in details and counted manually the time spent on each app and it turned out that the calculation is appearing correctly in my app but Phone settings showing quite less time on top (Day).

Crash within com.apple.CFNetwork.Connection , specifically due to EXC_BAD_ACCESS KERN_INVALID_ADDRESS. The crash occurred within the nghttp2_session_del() function indicating a problem with the nghttp2 library, which is commonly used for HTTP/2 communication. This points towards a memory management issue. EXC_BAD_ACCESS generally signifies that the application attempted to access memory it didn't have permission to access, often caused by using a pointer after it has been freed or pointing to an invalid memory address. ** Crashed: com.apple.CFNetwork.Connection 0 libapple_nghttp2.dylib 0xa6ec nghttp2_session_del + 124 1 CFNetwork 0xace4c + 428 2 CFNetwork 0xacc80 + 36 3 libdispatch.dylib 0x2370 _dispatch_call_block_and_release + 32 4 libdispatch.dylib 0x40d0 _dispatch_client_callout + 20 5 libdispatch.dylib 0xb6d8 _dispatch_lane_serial_drain + 744 6 libdispatch.dylib 0xc214 _dispatch_lane_invoke + 432 7 libdispatch.dylib 0xd670 _dispatch_workloop_invoke + 1732 8 libdispatch.dylib 0x17258 _dispatch_root_queue_drain_deferred_wlh + 288 9 libdispatch.dylib 0x16aa4 _dispatch_workloop_worker_thread + 540 10 libsystem_pthread.dylib 0x4c7c _pthread_wqthread + 288 11 libsystem_pthread.dylib 0x1488 start_wqthread + 8 ** The stack trace does not point to any code within our product codebase, hence making it difficult to pinpoint the root cause of the issue as there are multiple network calls running concurrently during the app's runtime.

NEFilterManager.shared().loadFromPreferences { loadError in DispatchQueue.global.async { ... } } the code above is executed in an app-like deamon and completionHandler was never invoked, same code in an application works fine.(they are both packed with content filter network system extension) is it because of the restriction of app-like deamon?

I see the log in my server and they told that PTT notification sent successful but bellow function not call from my app. Could you give me any suggest? func incomingPushResult(channelManager: PTChannelManager, channelUUID: UUID, pushPayload: [String: Any]) -> PTPushResult

Hey everyone, I’m trying to set up something that seems simple in theory but is turning out to be quite tricky: I want to create a system to remotely wake a sleeping Mac. Here’s what I’ve done so far: I’ve enabled “Wake for Network Access” in the settings. I’m sending Wake-on-LAN (WOL) magic packets to wake the machine. However, I’m running into the following issues: The WOL packets successfully wake the Mac, but only for about 30 seconds to 1 minute. Sending repeated packets doesn’t seem to reset the “awake time.” The Mac goes back to sleep even if background processes are running, or if I use tools like Amphetamine to keep it awake. From what I’ve read, waking a Mac via WOL or similar network events doesn’t fully wake the system. Instead, it enters a state called "darkwake." Interestingly, accessing shared drives via SMB fully wakes the Mac and keeps it awake as long as I’m actively browsing folders. I’ve also heard that a Plex server can keep the Mac awake as long as playback is detected from a client so they clearly have figured out something. I’ve posted in several forums but haven’t found a solution. Most people suggest “disabling sleep” entirely, which, to be honest, isn’t a solution at all. If anyone has insights into the mechanics of darkwake or knows how to fully wake a Mac remotely, I’d greatly appreciate your help! Thanks in advance!

I am developing a CarPlay app, that has been approved for EV Charging entitlement. Could you please confirm if the given entitlement supports CPSearchTemplate template as there is some confusion here. I tried using the template by referring to the below link, https://developer.apple.com/documentation/carplay/cpsearchtemplate Here is the snippet, class SearchCPView: UIResponder, CPSearchTemplateDelegate { var searchTemplate: CPSearchTemplate = CPSearchTemplate() override init() { super.init() searchTemplate.delegate = self } func getSearchTemplate(interfaceController: CPInterfaceController?) -> CPGridTemplate { let searchGridButton = CPGridButton(titleVariants: [CarplayButtonTitles.search], image: UIImage(named: ImagesConstants.CarPlay.searchGrid) ?? UIImage(), handler: {[self] _ in guard let controller = interfaceController else { return } controller.pushTemplate(self.searchTemplate, animated: true) { status, error in print(status) } }) let gridTemplate = CPGridTemplate(title: "", gridButtons: [searchGridButton]) return gridTemplate } func searchTemplate(_ searchTemplate: CPSearchTemplate, selectedResult item: CPListItem) async { print(item) } func searchTemplate(_ searchTemplate: CPSearchTemplate, updatedSearchText searchText: String) async -> [CPListItem] { print(searchText) return [CPListItem(text: "", detailText: "")] } } On push, I am getting an exception, *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unsupported object <CPSearchTemplate: 0x30056df00> <identifier: 28, userInfo: (null), tabTitle: (null), tabImage: (null), showsTabBadge: 0> passed to pushTemplate:animated:completion:.

Hi, I'm working on a macOS app that utilizes SwiftData to save some user generated content to their private databases. It is not clear to me at which point the app I made starts using the production database. I assumed that if I produce a Release build that it will be using the prod db, but that doesn't seem to be the case. I made the mistake of distributing my app to users before "going to prod" with CloudKit. So after I realized what I had done, I inspected my CloudKit dashboard and records and I found the following: For my personal developer account the data is saved in the Developer database correctly and I can inspect it. When I use the "Act as iCloud account" feature and use one of my other accounts to inspect the data, I notice that for the other user, the data is neither in the Development environment nor the Production environment. Which leads me to believe it is only stored locally on that user's machine, since the app does in fact work, it's just not syncing with other devices of the same user. So, my question is: how do I "deploy to production"? I know that there is a Deploy Schema Changes button in the CloudKit dashboard. At which point should I press that? If I press it now, before distributing a new version of my app, will that somehow "signal" the already running apps on user's machines to start using the Production database? Is there a setting in Xcode that I need to check for my Release build, so that the app does in fact start using the production db? Is there a way to detect in the code whether the app is using the Production database or not? It would be useful so I can write appropriate migration logic, since I don't want to loose existing data users already have saved locally.

I have an app available for download in the Apple App Store. The app sends local notifications, which are scheduled at the user's request once the app launches. I've recently learned that when new versions of my app are deployed and automatically update on the user's device, previously scheduled local notifications are deleted. Given my app design, the user can re-launch the app in order to re-schedule the local notifications. This is a bit of a problem, though, because part of my app's value is in reminding the user - so after requesting a local notification, the user expects to receive a local notification and then launch the app, not the other way around. Given this, I've been exploring solutions so my app continues to function as expected (including delivering local notifications, even if the app hasn't yet been launched) after an app update. I've explored .backgroundTasks(), but they too are apparently deleted with an app update and require the app to be re-launched first to work as expected. Another solution might be to use push notifications instead of local notifications, but that seems like a very involved solution if I'm just looking to make sure that local notifications persist after an app update. I can't be the only person to have this dilemma - am I overlooking a simple solution?

I've got an application built on top of SwiftData (+ CloudKit) which is published to App Store. I've got a problem where on each app update, the data saved in the database is duplicated to the end user. Obviously this isn't wanted behaviour, and I'm really looking forward to fixing it. However, given the restrictions of SwiftData, I haven't found a single fix for this. The data duplication happens automatically on the first initial sync after the update. My guess is that it's because it doesn't detect the data already in the device, so it pulls all data from iCloud and appends it to the database where data in reality exists.

Given that iOS 18.2 is out and following documentation and WWDC example (limited to iOS 18.2+), I am attempting to use @AssistantIntent(schema: .system.search) along an AppIntent. Questions: Has anyone made this to work on a real device?! In my case (code below): when I run the intent from Shortcuts or Siri, it does NOT open the App but only calls the perform method (and the App is not foregrounded) -- changing openAppWhenRun has no effect! Strangely: If my App was backgrounded before invocation and I foreground it after, it has navigated to Search but just not foregrounded the App! Am I doing anything wrong? (adding @Parameter etc doesn't change anything). Where is the intelligence here? The criteria parameter can NOT be used in the Siri phrase -- build error if you try that since only AppEntity/AppEnum is permitted as variable in Siri phrase but not a StringSearchCriteria. Said otherwise: What's the gain in using @AssistantIntent(schema: .system.search) vs a regular AppIntent in this case?! Some code: @available(iOS 18.2, *) @AssistantIntent(schema: .system.search) struct MySearchIntent: ShowInAppSearchResultsIntent { static let searchScopes: [StringSearchScope] = [.general] static let openAppWhenRun = true var criteria: StringSearchCriteria @MainActor func perform() async throws -> some IntentResult { NavigationHandler().to(.search(.init(query: criteria.term)), from: .siri) return .result() } } Along with this ShortCut in AppShortcutsProvider: AppShortcut( intent: MySearchIntent(), phrases: [ "Search \(.applicationName)" ], shortTitle: "Search", systemImageName: "magnifyingglass" )

Hello, We are a happy user of WeatherKit REST API. When can I expect weatherAlerts to work in Japan? The availability endpoint doesn't return weatherAlerts and I hope it's coming soon.

DESCRIPTION OF PROBLEM Logs and data from our application indicate various errors that strongly suggest that our application is being launched in a state in which the device is likely locked. We are looking for guidance on how to identify, debug, reproduce, and fix these cases. Our application does not use any of the common mechanisms for background activity, such as Background App Refresh, Navigation, Audio, etc. Errors we get in our logs such as "authorization denied (code: 23)" when trying to access a file in our app's container on disk (a simple disk cache for data our application uses) strongly suggest that the device is operating in a state, such as being locked, where our application lacks the requisite permissions it would normally have during operation. Furthermore, attempts to access authentication information stored in the keychain also fails. We use kSecAttrAccessibleWhenUnlocked when accessing items we store in the keychain. We have investigated "Prewarming", as well as our notification extension that helps process incoming push notifications, but cannot find any way to recreate this behavior. Are there any steps Apple engineers can recommend to triage and debug this? Some additional questions that would help us: What are all of the symptoms that we can look for if prewarming escapes the intended execution context? What are all of the circumstances in which we would be unauthorized to access the app’s documents/file directories even if it works correctly in normal operation? STEPS TO REPRODUCE Unfortunately, we are unable to forcibly reproduce this behavior in our application, so we're looking for guidance on how we might simulate this behavior in Xcode / Instruments. Are there tools that Apple provides that would allow us to simulate certain behaviors like prewarming to verify our application's functionality? Are there other reasons our application might be launched while the device is locked? Are there other reasons we would receive security errors when accessing the keychain or disk that are unrelated to the device being locked?

You are probably aware of the upcoming root certificate change for any servers you might have that you use to send push notifications by connection to APNs. If you are not, here is the announcement. We have been getting some questions about this, and understand not everyone is familiar with their server setup. First, we would like to clarify that this is only a change to your server's certificate trust store. You do not need to update anything else, like your APNs push certificates, the build certificates and provisioning profiles for your team/app, and so on. All you need to do is to install the mentioned new root certificate to your push server's trust store. If you are using a 3rd party push provider, it is them who will need to handle their servers. But you may want to double check with them nevertheless. If you are managing your own push servers that connect to APNs directly, then it is your responsibility to download and install the root certificate mentioned in the above link on your server(s). Unfortunately we cannot provide specific instructions on how to install this root certificate on every kind of server out there. Each server operating system/push server software will have different ways these root certificates are installed, which is out of scope of our support abilities. If you are not sure how to do this, I would recommend you seek help for this from your server-side developers or server admins. Or, if you don't have access to such resources, you can ask the support channels for your system the question: How do I install a root certificate? We have setup a test server at 17.188.143.34:443 that you can use to try and send pushes to test whether your new root certificate is correctly installed. An alternative way to test this would be, from a terminal prompt: openssl s_client -connect 17.188.143.34:443 -servername api.sandbox.push.apple.com -verifyCAfile USERTrustRSACertificationAuthority.crt -showcerts Change the parameter to the -verifyCAfile argument to point to your trust store, and it should allow you to validate Sample return results would be: Connecting to 17.188.143.34 CONNECTED(00000003) depth=2 C=US, ST=New Jersey, L=Jersey City, O=The USERTRUST Network, CN=USERTrust RSA Certification Authority verify return:1 depth=1 CN=Apple Public Server RSA CA 11 - G1, O=Apple Inc., ST=California, C=US verify return:1 depth=0 C=US, ST=California, O=Apple Inc., CN=api.sandbox.push.apple.com verify return:1 Argun Tekant /  DTS Engineer / Core Technologies

If an app has a text filtering extension and associated server that the iPhone OS communicates with, then how can that communication be authenticated? In other words, how can the server verify that the request is valid and coming from the iPhone and not from some spoofer? If somebody reverse engineers the associated domain urls our of the app's info.plist or entitlement files and calls the server url directly, then how can the server detect this has occurred and the request is not coming from the iPhone OS of a handset on which the app is installed?
