User Profile

We got an app for iPad which has two targets one for the App itself (MainApp target ) and another one for the Driver ( Driver Target ) using DriverKit. The app works fine in Development, but I'm trying to distribute it with adhoc. I've requested the Distribution Entitlement to Apple, after getting it, the App Id for the Driver has the following Capabilities: DriverKit, DriverKit (development), DriverKit USB Transport (development), DriverKit USB Transport - VendorID, In-App Purchase Now in the profile section, I've created a adhoc profile for the Driver AppId (Identifier). Obviously I've also created an Adhoc profile for the Main AppId Finally in the Signing & Capabilities Section I set up the profiles for MainApp target, int the Debug one I set up the Development one and int the Release one I set up the adhoc one. I do the same in the Driver Target, but when I set up the Adhoc one in the Release, I've got a warning: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile Also interestingly the Signing Certificate section says: None I also set up the Capabilities for the Driver Target: DriverKit USB Transport - VendorID DriverKit USB Transport ( Development ) Inside these capabilities I set up the vendor ID as dictionary The problem is, if I try to Archive the app I will get the previous Warning message as error: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile. Any idea what I'm missing? Thanks

After DriverKit being released last year, I wonder if the background mode External accessory communication in Background Modes applies also for drivers made with DriverKit. Is this mode only for products in the MFi group? If so, is there any plans to include DriverKit in this group in order to get data from an external device in the background, which is not in the MFi group?

I wonder if it's possible to show a popup when a device is plugged in the iOS device but the driver/app is not installed. I've seen this before when old days without DriverKit where a notification was shown to help the user. If the user accepted the popup the Apple store opened with the page download the particular app to install the driver for the device. Thanks

I'm building a driver in C++ for my iPad using DriverKit. I'm trying to make a request to a control endpoint, so I'm trying to use DeviceRequest: https://developer.apple.com/documentation/usbdriverkit/iousbhostinterface/3182582-devicerequest But the first parameter ask for USBmakebmRequestType which it's a macro defined in IOKit > USB.h I tried to #include <IOKit/USB.h> and #include <IOKit/usb/USB.h> and  but it doesn't find the header. Any idea? thanks.

I'm trying to create a driver for my usb device, using iOS and DriverKit. I'm basing my code in the example used in WWDC: https://github.com/knightsc/USBApp My driver starts fine when the device is connected and the readCompleted method is called fine, but the action->GetReference() gets only \0 characteres. Also in order to know that the usb device is actually working I've connected it to my mac first and using PyUSB I can see that it's returning data in chunks of 1024 bytes in the interface 0. This is the data I get in PyUSB: array('B', [6, 0, 1, 0, 2, 0, 3, 0, 4, 0, 5, 0, 6, 0, 7, 0, 8, 0, 9, 0, 10, 0, 11, 0, 12, 0, 13, 0, 14, 0, 15, 0, 16, 0, 17, 0, 18, 0, 19, 0, 20, 0, 21, 0, 22, 0, 23, 0, 24, 0, 25, 0, 26, 0, 27, 0, 28, 0, 29, 0, 30, 0, 31, 0, 32, 0, 33, 0, 34, 0, 35, 0, 36, 0, 37, 0, 38, 0, 39, 0, 40, 0, 41, 0, 42, 0, 43, 0, 44, 0, 45, 0, 46, 0, 47, 0, 48, 0, 49, 0, 50, 0, 51, 0, 52, 0, 53, 0, 54, 0, 55, 0, 56, 0, 57, 0, 58, 0, 59, 0, 60, 0, 61, 0, 62, 0, 63, 0, 64, 0, 65, 0, 66, 0, 67, 0, 68, 0, 69, 0, 70, 0, 71, 0, 72, 0, 73, 0, 74, 0, 75, 0, 76, 0, 77, 0, 78, 0, 79, 0, 80, 0, 81, 0, 82, 0, 83, 0, 84, 0, 85, 0, 86, 0, 87, 0, 88, 0, 89, 0, 90, 0, 91, 0, 92, 0, 93, 0, 94, 0, 95, 0, 96, 0, 97, 0, 98, 0, 99, 0, 100, 0, 101, 0, 102, 0, 103, 0, 104, 0, 105, 0, 106, 0, 107, 0, 108, 0, 109, 0, 110, 0, 111, 0, 112, 0, 113, 0, 114, 0, 115, 0, 116, 0, 117, 0, 118, 0, 119, 0, 120, 0, 121, 0, 122, 0, 123, 0, 124, 0, 125, 0, 126, 0, 127, 0, 128, 0, 129, 0, 130, 0, 131, 0, 132, 0, 133, 0, 134, 0, 135, 0, 136, 0, 137, 0, 138, 0, 139, 0, 140, 0, 141, 0, 142, 0, 143, 0, 144, 0, 145, 0, 146, 0, 147, 0, 148, 0, 149, 0, 150, 0, 151, 0, 152, 0, 153, 0, 154, 0, 155, 0, 156, 0, 157, 0, 158, 0, 159, 0, 160, 0, 161, 0, 162, 0, 163, 0, 164, 0, 165, 0, 166, 0, 167, 0, 168, 0, 169, 0, 170, 0, 171, 0, 172, 0, 173, 0, 174, 0, 175, 0, 176, 0, 177, 0, 178, 0, 179, 0, 180, 0, 181, 0, 182, 0, 183, 0, 184, 0, 185, 0, 186, 0, 187, 0, 188, 0, 189, 0, 190, 0, 191, 0, 192, 0, 193, 0, 194, 0, 195, 0, 196, 0, 197, 0, 198, 0, 199, 0, 200, 0, 201, 0, 202, 0, 203, 0, 204, 0, 205, 0, 206, 0, 207, 0, 208, 0, 209, 0, 210, 0, 211, 0, 212, 0, 213, 0, 214, 0, 215, 0, 216, 0, 217, 0, 218, 0, 219, 0, 220, 0, 221, 0, 222, 0, 223, 0, 224, 0, 225, 0, 226, 0, 227, 0, 228, 0, 229, 0, 230, 0, 231, 0, 232, 0, 233, 0, 234, 0, 235, 0, 236, 0, 237, 0, 238, 0, 239, 0, 240, 0, 241, 0, 242, 0, 243, 0, 244, 0, 245, 0, 246, 0, 247, 0, 248, 0, 249, 0, 250, 0, 251, 0, 252, 0, 253, 0, 254, 0, 255, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]) This is the Ivars: struct Mk1dDriver_IVars { IOUSBHostInterface *interface; IOUSBHostPipe *inPipe; OSAction *ioCompleteCallback; IOBufferMemoryDescriptor *inData; uint16_t maxPacketSize; }; This is the Start method: kern_return_t IMPL(Mk1dDriver, Start) { kern_return_t ret; IOUSBStandardEndpointDescriptors descriptors; ret = Start(provider, SUPERDISPATCH); __Require(kIOReturnSuccess == ret, Exit); ret = RegisterService(); if (ret != kIOReturnSuccess) { Log("Start() - Failed to register service with error: 0x%08x.", ret); goto Exit; } ivars->interface = OSDynamicCast(IOUSBHostInterface, provider); __Require_Action(NULL != ivars->interface, Exit, ret = kIOReturnNoDevice); ret = ivars->interface->Open(this, 0, NULL); __Require(kIOReturnSuccess == ret, Exit); ret = ivars->interface->CopyPipe(kMyEndpointAddress, &ivars->inPipe); __Require(kIOReturnSuccess == ret, Exit); ret = ivars->interface->CreateIOBuffer(kIOMemoryDirectionIn, 1024, &ivars->inData); __Require(kIOReturnSuccess == ret, Exit); ret = OSAction::Create(this, Mk1dDriver_ReadComplete_ID, IOUSBHostPipe_CompleteAsyncIO_ID, 0, &ivars->ioCompleteCallback); __Require(kIOReturnSuccess == ret, Exit); ret = ivars->inPipe->AsyncIO(ivars->inData, ivars->maxPacketSize, ivars->ioCompleteCallback, 0); __Require(kIOReturnSuccess == ret, Exit); os_log(OS_LOG_DEFAULT,"Finish"); // WWDC slides don't show the full function // i.e. this is still unfinished Exit: return ret; } The only difference in this compared with the code from Apple is that I set capacity in the method CreateIOBuffer to 1024. This is because if I leave it to 0 it will return an error that memory could not be allocated: kIOReturnNoMemory And the ReadComplete method: void IMPL(Mk1dDriver, ReadComplete) { char output[1024]; memcpy(action->GetReference(), &output, 1024); os_log(OS_LOG_DEFAULT,"ReadComplete"); If I put a breakpoint in the log, I can see all the positions in output will be \0 Any idea what I'm doing wrong? Could this be because the iPad is a device under Supervision? Thanks

I'm trying to adapt this example to use it in iPadOS: https://developer.apple.com/library/archive/documentation/DeviceDrivers/Conceptual/USBBook/USBDeviceInterfaces/USBDevInterfaces.html#//apple_ref/doc/uid/TP40002645-BBIDDHCI I'm particularly having problem when I try to use IOUSBDeviceInterface. I'm importing #include <IOKit/IOKitLib.h> But when I'm trying to have a method like this: IOReturn ConfigureDevice(IOUSBDeviceInterface **dev) I've get the error:Unknown type name 'IOUSBDeviceInterface' I'm using  Xcode - Version 14.0 beta 3 (14A5270f) Any ideas? Thanks
