Hello everyone. After a lot of research and some tests from various sources, I have actually built a small SerialDriverKit IOUserSerial driver. Unfortunately, the documentation on the official sites is tight-lipped and very thin. At least I have a running driver instance. Now my request and question: Can anyone give me a tip on how to get the data from the serial client? I have already called IOUserSerial::ConnectQueues(...) in the IOUserSerial::Start() method and I got the IOMemoryDescriptors for interrupt, RX and TX to my driver instance. I tried to get access to the memory in the method IOUserSerial::TxDataAvailable() with IOMemoryDescriptor::CreateMapping(...). Unfortunately, no data is coming in. It's always 0x00. Here is the OS log: kernel: (org.eof.tools.VSPDriver.dext) kernel: (org.eof.tools.VSPDriver.dext) [VSPDriver] init called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] constructor called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriver] start called. kernel: (org.eof.tools.VSPDriver.dext) IOUserSerial::: 40 0x600000da4058 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] Start called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] Connect INT/RX/TX buffer. kernel: (org.eof.tools.VSPDriver.dext) IOUserSerial::: 59 0x600000da4058 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] prepare TCP socket. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriver] driver started successfully. kernel: DK: VSPDriver-0x100000753::start(IOUserResources-0x100000116) ok ... ... some client serial setup stuff ... kernel: (IOUserSerial) IOUserSerial::hwResetFIFO: 1076 ==>0 kernel: (IOUserSerial) IOUserSerial::hwResetFIFO: 1076 <== kernel: (IOUserSerial) IOUserSerial::hwResetFIFO: 1076 locklevel = 1 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriver] HwResetFIFO called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] HwResetFIFO called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] HwResetFIFO: tx=0 rx=1 kernel: (IOUserSerial) IOUserSerial::hwResetFIFO: 1076 ==>0 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriver] TxDataAvailable called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable called. kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: address=0x104c22000 length=16384 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: debug TX buffer kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00 kernel: (org.eof.tools.VSPDriver.dext) [VSPDriverPrivate] TxDataAvailable: TX> 0x00

When trying to run my document-based iPad app using iPadOS 18 beta and Xcode 16 beta, I get an error like the following after opening a document: Thread 1: Fatal error: Failed to identify a store that can hold instances of SwiftData._KKMDBackingData<MyProject.MyModel> from [:] In order to help track down what is going wrong, I downloaded the sample app from WWDC23 session "Build an app with SwiftData" found here: https://developer.apple.com/documentation/swiftui/building-a-document-based-app-using-swiftdata When I try to run the end-state of that sample code, I get a similar error when running the app on my iPad and creating a new deck: Thread 1: Fatal error: Failed to identify a store that can hold instances of SwiftData._KKMDBackingData<SwiftDataFlashCardSample.Card> from [:] Given that the sample project is generating the same error as my own project, is this a problem with SwiftData and document-based apps in general? Or is there a change of approach that I should try?

I'm using TestFlight to test an app with payment/subscription functionality. I created sandbox accounts in AppStore Connect accordingly to be able to test the subscriptions. I'm logged in with the sandbox account. When I try to subscribe in the App the wrong account (this is my actual real AppleID) is used for the subscription although it is recognized that this is just a sandbox subscription. I tried: logging off/on into the sandbox account creating a totally new sandbox account trying to trigger the payment with no logged in sandbox account The result is always: in the payment popup it is stated that the purchase account will be my original AppleID and not a sandbox account. How can I switch the accounts? Is this a bug at Apple's side somehow?

We have had a small number of users of our mac app complaining that the app suddenly can't detect their subscription or previous purchase history. These users are not new, and have been using the app successfully for some time. In the app we do this using the following (very standard) code at app startup: let result: VerificationResult<AppTransaction> = try await AppTransaction.shared For those users experiencing the failure, the result is coming back as unverified. So far we've been unable to find the cause or a solution, but it seems to have become worse with the release of macOS 15.4. We've tried resetting, rebooting and reinstalling the app. It's worth adding the (probably obvious) that it's impossible to test or fault-find with this, because we can't replicate the issue in a development environment. Any suggestions gratefully received.

My team has developed an app with a Matter commissioner feature (for own ecosystem) using the Matter framework on the MatterSupport extension. Recently, we've noticed that commissioning Matter devices with the MatterSupport extension has become very unstable. Occasionally, the HomeUIService stops the flow after commissioning to the first fabric successfully, displaying the error: "Failed to perform Matter device setup: Error Domain=HMErrorDomain Code=2." (normally, it should send open commissioning window to the device and then add the device to the 2nd fabric). The issue is never seen before until recently few weeks and there is no code changes in the app. We are suspected that there is some data that fail to download from the icloud or apple account that cause this problem. For evaluation, we tried removing the HomeSupport extension and run the Matter framework directly in developer mode, this issue disappears, and commissioning works without any problems.

Noticing a few issues with Screen Savers in macOS Tahoe developer beta 1 : The command open x-apple.systempreferences:com.apple.ScreenSaver-Settings.extension no longer works to open the Screen Savers preference pane. The reason? There is no longer a Screen Saver preference pane - it still exists, but it's now a Modal dialog (that can not be resized) that is opened from within the Wallpaper preference pane, by clicking a button. Something funny is happening with legacyScreensaver - I think that ScreenSaverView.Init(frame:isPreview) may be passing wrong values, e.g. the isPreview boolean is false in Preview mode? I've submitted Feedback # FB17895600 about some of these, and will report back more as I figure things out. Please feel free to add to this thread, thanks!

I completed the CallKit Demo with the same code. When I changed to LiveCommunicationKit, the code goes perfectly when the app is in foreground, but it crashed in background. If I changed the reportIncoming method from LCK to CallKit, it goes well. What is the reason? I changed the method from func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) to func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType) async it crashed before show the print "receive voip noti".

Hello everyone, I have been working on a macOS app that utilizes push notifications for the past year. Up until recently, everything was functioning correctly. However, now I'm experiencing issues where push notifications are either not being delivered at all or are experiencing significant delays, sometimes up to 10 minutes. Setting the priority header to 10 hasn't made any difference. I am currently using development push notifications, but the issue persists when switching to the production environment. I'm curious if anyone else has encountered similar problems. When checking the push console, it frequently reports that the device is offline, even though it's actually online ("discarded as device was offline"). Occasionally, notifications are delivered promptly, but this is becoming increasingly infrequent. This issue has been consistently reported by our testers, particularly after they updated to macOS Sonoma. Any insights or assistance you can provide would be greatly appreciated.

We create custom VPN tunnel by overriding PacketTunnelProvider on MacOS. Normal VPN connection works seamlessly. But if we enable onDemand rules on VPN manager, intemittently during tunnel creation via OnDemand, internet goes away on machine leading to a connection stuck state. Why does internet goes away during tunnel creation?

On a MacBook Pro, 16GB of RAM, 500 GB SSD, OS Sequoia 15.7.1, M3 chip, I am running some python3 code in a conda environment that requires lots of RAM and sure enough, once physical memory is almost exhausted, swapfiles of about 1GB each start being created, which I can see in /System/Volumes/VM. This folder has about 470 GB of available space at the start of the process (I can see this through get info) however, once about 40 or so swapfiles are created, for a total of about 40GB of virtual memory occupied (and thus still plenty of available space in VM), zsh kills the python process responsible for the RAM usage (notably, it does not kill another python process using only about 100 MB of RAM). The message received is "zsh: killed" in the tmux pane where the logging of the process is printed. All the documentation I was able to consult says that macOS is designed to use up to all available storage on the startup disk (which is the one I am using since I have only one disk and the available space aforementioned reflects this) for swapping, when physical RAM is not enough. Then why is the process killed long before the swapping area is exhausted? In contrast, the same process on a Linux machine (basic python venv here) just keeps swapping, and never gets killed until swap area is exhausted. One last note, I do not have administrator rights on this device, so I could not run dmesg to retrieve more precise information, I can only check with df -h how the swap area increases little by little. My employer's IT team confirmed that they do not mess with memory usage on managed profiles, so macOS is just doing its thing. Thanks for any insight you can share on this issue, is it a known bug (perhaps with conda/python environments) or is it expected behaviour? Is there a way to keep the process from being killed?

I added a Content Filter to my app, and when running it in Xcode (Debug/Release), I get the expected permission prompt: "Would like to filter network content (Allow / Don't Allow)". However, when I install the app via TestFlight, this prompt doesn’t appear at all, and the feature doesn’t work. Is there a special configuration required for TestFlight? Has anyone encountered this issue before? Thanks!

Unexpected behavior encountered when scanning NFC tags. Imagine a link shortener web service where users can create lots of different URLs that are hosted on the same domain eg, https://short.com/unique-path The service has optional App Clip capability -- users can select any of their links and have the service create an App Clip for the selected link(s). Users can encode their URLs into NFC tags and have their customers scan NFC tags. Let's take just two URLs for example: https://short.com/foo https://short.com/bar The /foo link does have an App Clip associated with it while /bar does not have it. Each link has been encoded into appropriate NFC tag. Expected behavior when scanning from an iPhone: /foo -- shows an App Clip popup. /bar -- shows a "Open in Safari" default notification. What's actually happening /foo -- opens App Clip poput with correct metadata (title, subtitle, image) which is totally expected behavior. /bar (the one that doesn't have app clip associated with it) -- opens an App-Clip-like popup with the following error: CPSErrorDomainError 2 (see attachment below) So for some reason when someone scans an NFC tag with a URL that is not an App Clip and never has been -- it always shows that error regardless whether the URL exists or does not exist. I've tried few different/random URLs (which don't have an App Clip associated with it) and all of them show the same error. Additional details: All links use the same domain and URL format: domain.com/path where path is a short string of random a-Z characters. All App Clips are created at the same iOS app. AASA is good: Cache and Debug -- both green. This issue has happened to lots of users on lots of different iPhones and iOS'. Since the issue's been happening to lots of different users on different iPhone(s)/iOS' no sysdiagnose is attached. Actually it works the same on every device/iOS we've tried. Before submitting the issue, I've found few other developers reporting the same issue. What's interesting though is none of the links I've went through comes with a definite answer and it seems like this issue just randomly comes and goes without any specific changes on the server and/or iOS app. Dropping the links of similar issues below. https://developer.apple.com/forums/thread/671433 https://developer.apple.com/forums/thread/665969 https://developer.apple.com/forums/thread/775316 https://developer.apple.com/forums/thread/764545

Prior to Sequoia, Mac Catalyst Apps worked fine when using group folders that started with group. They now get an alert that the Mac Catalyst app is trying to access data from other applications. This may also impact some SwiftUI developers. According to this the documentation for the App Group Entitlements entitlement, on macOS we should begin use the Team Identifier instead of group. Should Mac Catalyst follow the macOS or iOS rules for com.apple.security.application-groups? If they should need to follow the macOS rules now, that creates several issues for developers. We would now need separate build targets to pick up the different Entitlements files. More distressing is that we would need to do some kind of migration process to get our files to the new location. There wouldn't be a transparent way to do so where the user wasn't warned about the application accessing files that don't belong to it. Any clarification on what Mac Catalyst developers should be doing to prepare for Sequoia would be greatly appreciated.

Our app has a network extension (as I've mentioned lots 😄). We do an upgrade by downloading the new package, stopping & removing all of our components except for the network extension, and then installing the new package, which then loads a LaunchAgent causing the containing app to run. (The only difference between a new install and upgrade is the old extension is left running, but not having anything to tell it what to do, just logs and continues.) On some (but not all) upgrades... nothing ends up able to communicate via XPC with the Network Extension. My simplest cli program to talk to it gets Could not create proxy: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named blah was invalidated: failed at lookup with error 3 - No such process." UserInfo={NSDebugDescription=The connection to service named bla was invalidated: failed at lookup with error 3 - No such process.} Could not communicate with blah Restarting the extension by doing a kill -9 doesn't fix it; neither does restarting the control daemon. The only solution we've come across so far is rebooting. I filed FB11086599 about this, but has anyone thoughts about this?

I'm working on a project that says it's to be based on the QNE2TransparentProxyMac sample code but don't have the original sample code. Can I get a pointer to the sample code and documentation please? Google search didn't find it for some reason. Thanks! Peter

Hello! https://github.com/apple/live-caller-id-lookup-example/blob/main/Sources/PIRService/PIRService.docc/DataFormat.md The link above shows the data format that the user who gets a call, can get. I wonder if it is also possible to add other fields, for example: "summary". I am currently in the design-phase of an app that aims to present what the last call between the two parties was about, and that information can be gotten from an API that I will build according to Apple's principles that is comaptible with the Live Caller ID Lookup protocol. Therefore adding a field that will present a short summary of the last call will be very handy. Is that possible?

I have a command line utility I wrote that has been working great up until Sequoia that reads the macro keys from a Logitech G600 gaming mouse and turns it in to custom commands. it was using the following code, checking if usage was 0x80: IOHIDManagerRegisterInputValueCallback( g600HIDManager, { _, returnResult, callbackSender, valueRef in let elem = IOHIDValueGetElement(valueRef) let usage = IOHIDElementGetUsage(elem) let pressed = IOHIDValueGetIntegerValue(valueRef) Now i'm having issues with opening the HID manager: IOHIDManagerOpen(g600HIDManager, IOOptionBits.zero) After changing the system security from permissive to restrictive, It's giving the error code 0xE00002E2, or no permission. I can't easily add the sandbox entitlements as this is just a simple CLI application, not a bundled app, and even after setting back to csrutil disable, i'm still getting this error. So now i'm trying to turn it in to a bundled app and use CoreHID instead. Unfortunately I'm not getting any notifications that aren't the mouse itself. From the above code that was working before, i was looking for usage values of 0x80. I'm guessing that directly corresponds to the usage 0x80 in the HID descriptor. I am receiving notifications via await deviceClient!.monitorNotifications(reportIDsToMonitor: [] , elementsToMonitor: [] ) which should pick up everything for the device. I know the usage i'm looking for is referenced in the device client because it's in the deviceClient.elements collection. So is there something in CoreHID that specifically blocks Vendor specified Usage pages from being picked up by notifications? I've also tried just requesting the elements using let elemToMon = await deviceClient?.elements.filter({ ele in return ele.usage.page == 0xFF80 && ele.usage.usage == 0x80 }) let request = HIDDeviceClient.RequestElementUpdate(elements: elemToMon!) let results = await deviceClient!.updateElements([request]) but that call errors (still trying to figure out exactly how it errors). Any help would be appreciated, either in figuring out why i'm not getting the HID reports in question using CoreHID, or even what has changed that is causing me to not be able to use IOKit.hid anymore. Thanks in advance!

Aloha. Opening and closing VPN tunnels results in as many utun interfaces as the amount of times the tunnel has been opened. These interfaces stay present and seem to be removed only upon system reboot. We are using the NetworkExtension as a SystemExtension on macOS to create the virtual interfaces. Is this the normal behaviour. Has anybody else experienced this? utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1380 inet6 fe80::8038:c353:17cd:c422%utun0 prefixlen 64 scopeid 0xf nd6 options=201<PERFORMNUD,DAD> utun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000 inet6 fe80::cfb6:1324:d7e9:5d5%utun1 prefixlen 64 scopeid 0x10 nd6 options=201<PERFORMNUD,DAD> utun2: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun3: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun4: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun5: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun6: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun7: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun8: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>

I have simple non-consumable IAPs set up for an app on macOS. Testing in development with a local .storekit configuration file, everything works as expected. Testing in development with a remote Sandbox, everything also seems to work fine. Product names and prices fetch correctly, I am able to make purchases with a Sandbox account (both US and UK). Once I upload a build into TestFlight, IAPs no longer work. The tester would download the Beta app from TestFlight. They open a license manager and can see all the product names, descriptions and prices are pulled from Apple servers correctly (with the correct local currency as well!). So far so good. When trying to purchase any of the IAP, the following error appears: This is TestFlight so testers are using their real Apple ID. My understanding is that they should continue using their production credentials and a TestFlight Sandbox would be configured behind the scenes automatically. This error always says the users cannot purchase from a US store and must switch to [whatever user’s actual store location is] store. For example, my account is based in the UK, has got a UK billing address and a UK payment method, and the error tells me to switch to the UK store. People in Canada get a similar error - you must switch from the US store to Canadian. The error makes no sense, the account is already in the desired country. Clicking on the “Change Store” button opens the App Store app and displays another error: “Cannot Connect to App Store”. Clicking Retry just results in this errors showing again and again. Clicking OK takes us back to the failed IAP purchase and the final error message appears: “Purchase Error - Unable to Complete Request”. Things I’ve done / checked: IAPs are configured in App Store Connect and available for all regions prices are set for all regions in App Store Connect IAP name and description localisation in English (UK) IAP status is Ready to Submit, I don’t think I can go past that unless I make a production release (which I can’t until we fix the problem) IAP capabilities added in xcode the problem is not account, machine, or location dependent - every beta tester testing my app on TestFlight has the same issue, they each use a different account and have accounts in different countries double checked the App Store account location in the App Store settings - it is definitely matching the store this error is asking to switch to application exits at startup with error 173 if app receipt cannot be found - this one was suggested by the review team, I could not really find any documentation for it review team also suggested I should add com.apple.security.network.client to enable IAP connectivity. I did add that to one of the builds and it did not help. I am not really convinced this is necessary Any suggestions on what to check and what to try? I have run out of ideas.
