Hi guys,
I am developing an iOS application that turns iPhone into a HID peripheral. I have successfully added services and characteristics, and it can be paired with a Windows PC and works as expected.
However, after the app relaunch and services re-added, PC not able to re-connect to it automatically. It still shows "Paired" on the PC rather than "Connnected" and no subscribe event received from CB. The user has to remove the device and do the pair again.
I think the reason is that a new peripheral manager created after re-launch, it doesn't have previous connections' information (uuid or secure key). Hence, PC not able to talk to it anymore.
My questions are:
Is it the real reason for this?
Any chance app can store the peripheral manager or the connection information? So that can pick it up next run.
Any chance can setup to "Just works" mode? Maybe can make the reconnection working?
I have read thru the CB documents, and didn't find answer there. Just trying with the forum if any luck...

I'm try to use CoreHID to communicate with a usb hid device that sends custom reports. I have been able to create a client, but when I try to access the elements I get this:
IOServiceOpen failed: 0xe00002e2
also in:
client.monitorNotifications(reportIDsToMonitor: [HIDReportID.allReports], elementsToMonitor: []) {...
What do I put into "elementsToMonitor: []" array?
how can i upgrade my mac 10.13 if it does let me go to [https://beta.apple.com/sp/betaprogram/apfsfusion]. page
Here is project I am researching: https://developer.apple.com/documentation/hiddriverkit/handling_stylus_input_from_a_human_interface_device
I have a Touch screen and I want:
can control this screen, I can enable extension and control Touch screen successfully.
can pen on this screen. To do this, I need to send X,Y to StylusApp(AppKit) But I Can not send X, Y to Swift StylusApp
Eventhough I can log X,Y it by default code:
But I don't know how to send it to AppKit to Pen.
I have research about communicate Driver and Client: https://developer.apple.com/documentation/driverkit/communicating_between_a_driverkit_extension_and_a_client_app#4324306 but seem HID driver don't support inheritance from IOUserClient:
Bonjour,
Depuis la mise à jour vers ios18 je n’arrive plus à accéder au réglage temps d’écran.
la fonction me demande de me connecter, mais après l’identification plus rien impossible d’accéder a la fonctio.
Hi,
I'm trying to test "https://developer.apple.com/documentation/networkingdriverkit/connecting_a_network_driver" on MacBook Pro M3 with 14.5 Sonoma, XCode 15.4, SIP is disabled.
Build steps are succesful, after running App, "Install Dext" is succesful, there is no error in XCode; "systemextensionctl list" show a record for "com.apple.system_extension.driver_extension" with [ activated enabled ] tag.
But, "ioreg" doesn't show any service for the dext; and no new interface with name "enXX" appears in System Settings in contrast to what the document describes. In addition, seldomly my device experiences crash when the dext remains installed where crash report points "IOReg" function.
I tried also Driver Kit Sample ( https://developer.apple.com/documentation/driverkit/driverkit_sample_code ) and a github project based on this sample having last commits 9 months ago. However, Dext installation reveals similar behavior and "Communicate with Dext" step is unsuccessful with the message "Driver is not connected".
Is there an updated version of Networking Driver Kit documentation to reach a running sample app for Sonoma 14.5?
Thanks.
Hi,
I'm trying to test the NetworkingDriverKitSampleApp at https://developer.apple.com/documentation/networkingdriverkit/connecting_a_network_driver for a while but I couldn't reach the final steps described in the documentation.
My setup: Xcode 15.4, MacBook Pro M3 with Sonoma 14.5, SIP is disabled.
I prepared the required provisinning profiles with required entitelements.
Dext and app builds successfully. Build path starts with "/Applications".
"Install Dext" operation is successful without any error after allowing necessary permission.
However, neither System Settings shows any new enXX interface, nor ioreg command shows a registered service while "systemextensionctl list" shows the expected result as a com.apple.system_extension.driver_extension record with [ activated enabled ].
I repeated the same steps for "Driver Kit Sample" at https://developer.apple.com/documentation/driverkit/driverkit_sample_code, "Install Dext" step succesful but "Communicate With Dext" results in "Driver is not connected" message. Similar to previous project, ioreg doesn't show any service for the dext while systemextensionctl lists [activeted enabled]. I also test an updated version of DriverKitSample at https://github.com/DanBurkhardt/DriverKitUserClientSample, which reproduced the same results.
Finally, my device experiences seldom crashes after passing sleep state when the dext remains installed; where crash report points "IOReg".
Is there any lacking steps on Apple documentation for Sonoma 14.5 or XCode 15.4 versions?
Thanks.
I'm trying to build an XCode project that contains an app and another target for the DriverKit, and run into the following linker issue:
ld: file cannot be open()ed, errno=2 path=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a in '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
My project has Code Coverage enabled. I noticed that if I disabled Code Coverage for all targets, I would be able to build successfully, and the driverKit would work as expected.
I wonder if it would be possible to build DriverKit without disabling code coverage.
Thanks
Upon taking a photo using the rear camera of my iPhone 14 Pro Max, I observed severe picture distortion. This issue severely undermines the functionality and reliability of the iPhone camera, raising serious concerns about its usability and trustworthiness.
The situation:
1A) On last week our development team applied on-line for three idVendors with the format as the following:
USB-VendorID: 547h(1351), 3488h(13448),4B4h(1204)
Describe your apps: it shall be functional equivalence of existing Android-SDK for X-ray sensor-models:...with 15..25 text lines of the description below
1B) We received auto-reply, that we granted all the the entitlements. We've expected to have entitlements like approx like the these:
<key>com.apple.developer.driverkit.transport.usb</key> <array>
<dict> <key>idVendor</key> <integer>1351</integer> </dict>
<dict> <key>idVendor</key> <integer>131448</integer> </dict>
<dict> <key>idVendor</key> <integer>1204</integer> </dict> </array>
1C) Unexpectingly (for us) ASCII-strings-fragment from our iOS-target-binary "com.rayence.dexta.driver" (built with automatic signing; seemingly this shall be our actual granted prvisionintg profile) looks as the next:
<plist version="1.0"> <dict> <key>com.apple.developer.driverkit</key> <true/><key>com.apple.developer.driverkit.transport.usb</key>
<array><dict> <key>idVendor</key> <string>*</string> </dict></array> </dict>
1D) Repectively, now we shall specify (in our dext's entitlements in XCOde-project)
<key>com.apple.developer.driverkit.transport.usb</key> <array>
<dict> <key>idVendor</key> <string>*</string> </dict> </array>
In DExt's info.plist we have "normal":
<key>IOKitPersonalities</key> <dict>
<key>IOKitPersonality_EzHD</key> <dict> blah-blah
<key>idVendor</key><integer>1351</integer>
<key>IOKitPersonality_EzR</key> <dict> blah-blah
<key>idVendor</key><integer>131448</integer>
<key>IOKitPersonality_EzR</key> <dict> blah-blah
<key>idVendor</key><integer>1204</integer>
blah-blah
Our ambiguities:
2a) Without exact "1D)", our DExt-installer-application never starts in iPAD. OS-loader generates obectievly-meaningless error-messages and seemingly-meaninglessly suggest to look "system-logs" (which seemingly don't contain relevant information)
2b) With exatct "1D)",
2ba) the reaction (presence/absence and timing of relevant console.app's messages) of our iPAD 17.4 on plugging/unplugging our gadgets look "non-logical". It isn't completly wrong but suspicious. E.g. our Swift-module randomly receive/dontreceive relevant events and can't connect communicate driver's instance for newly-attached physical gadgets. We realize, thses it could be our bugs; but we need disambiguation to debug the issues (or at least to be sure that the quirks are like in production system).
2bd) we would prefer debug/develop rather with real "idVendor=number nnn"s in provisioning profile (than with "idVendor=string *"). So we could be sure that quircs "2ba" are like in a production system.
Respective question:
Which format in on-line application ~1A) shall we use to obtain provisioning profile 1B)
Hello, as the title says, I am trying to access Bluetooth in a system daemon. I am running on MacOS Sonoma 14.5.
When initializing Bluetooth, my daemon received Unauthorized state.
I have tried to add my daemon in the system settings (System Preferences > Security & Privacy > Privacy > Bluetooth) "Allow applications to access Bluetooth" by adding the program executable path defined by the entry Program of my system daemon as suggested here: https://developer.apple.com/forums/thread/662459.
But I am still having the issue.
Writing a system daemon with Bluetooth is not my final goal. The bigger picture is the smartcard reader driver with Bluetooth access which as the same issue and the solution is probably related.
I do not remember how but my smartcard reader driver use to work with Bluetooth but it does now with the same Unauthorized error.
As far as I can see daemon and smartcard drivers does not have support for entitlement.
Here are the logs for my sample system daemon:

I'm trying to make an asynchronous bulk data read using IOUSBHostPipe AsyncIO/CompleteAsyncIO and send the data back to the user-space application using AsyncCompletion.
virtual void AsyncCompletion(OSAction *action, IOReturn status, const IOUserClientAsyncArgumentsArray asyncData, uint32_t asyncDataCount);
My understanding is that the IOUserClientAsyncArgumentsArray asyncData in AsyncCompletion method has a limited size of 128 bytes, and the data I need to send back is over 10k bytes.
Would it be possible to send such large data from the driver to the user-space application using async callback?
Thanks
Since the day i updated ios18 developer beta, screen time stops working and it wont let me access my apps under screen time lock despite of entering right password.
Urgent solution required asap.
please do something
I'm trying to communicate with an RS-485 device using a USB-to-RS-485 adapter based on a CP21012N. It's capable of speeds up to 3 Mbaud. However, when I call tcsetattr() with speed set to anything other than one of the predefined constants (using cfsetspeed()), I get an "Invalid argument" error back from the call.
Googling, I found https://github.com/avrdudes/avrdude/issues/771
Seems like macOS really can't accept baud rates outside the predefined set without resorting to ioctl?
Bjr. Je ne parviens plus à réinstaller aucune application après avoir formaté ou réinitialisé mon iPhone. Comment résoudre se problème rapidement.
mon système c'est IOS 17.5.1. Peut être faut-il faire une mise à jour du système pour résoudre définitivement ce problème d'installation d'applications.
sil vous plaît trouver une solution rapidement. Je veux récupérer mes données d’urgence. Merci

When application requires apple reciepts, apple server returns 21107 satus.
Why apple server return 21107?
I'm trying to make an asynchronous bulk data read using AsyncIO/CompleteAsyncIO.
The problem I'm facing is that the AsyncIO succeeds but CompleteAsyncIO/ReadComplete doesn't get called when the AsyncIO's completion timeout is set to 0.
Changing the completion timeout to a non-zero would trigger ReadComplete but I keep getting the (0x2d6) "I/O Timeout" error
Any idea what I'm doing wrong?
Also, is there any limit for the maximum buffer length the callback can accept?
Thanks.
struct MyDriver_IVars {
OSAction* callbackAction = nullptr; // registered callback action by app
IOUSBHostInterface* interface;
IOUSBHostPipe* pipe;
IOBufferMemoryDescriptor* inDataBuffer;
OSAction* ioCompleteCallback = nullptr; // read complete callback action
uint32_t MAX_LENGTH = 1024;
};

//AsyncCompletion(ivars->callbackAction, ..................
}

Where do I get. PerfPowerTelemetryClientRegistrationService which is suddenly missing from my system since upgrading to MacOS15/IOS18?
