Hello. In the case of certain apps, I confirmed that when I connected the Bluetooth of the vehicle, local notification is activated in the app and the app processor automatically runs when Bluetooth is connected. How can I do that? Thank you

In iPadOS 17.7 my driver shows up in settings just fine. After recompiling with Xcode 16 and installing my app (containing my driver) on iPadOS 18, the app shows up in settings but the driver-enable button is missing from Settings. When I plug-in my custom USB device, the app cannot detect it and I am left with no way to manually enable the driver, as I did in the previous version of iPadOS.

Upgraded my 2 machines to Sequoia 15 and consequently I am unable to print or scan with both machines. A 3rd machine which is not upgraded as yet is unaffected. AirPrint from iPhones is not affected. The printing process executes without error. The printer receives the job but does not actually execute the print. The machine behaves like the job in the queue is completed normally. No error message. Just no physical printout. Happens with all applications. When Scanning - fails to connect to device to enable scanning. error message after some time is attached

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: my_daemon [0x6000011b0000] activating connection: mach=true listener=false peer=false name=com.apple.server.bluetooth.le.att.xpc bluetoothd [0x7f804828e8a0] activating connection: mach=false listener=false peer=true name=com.apple.server.bluetooth.le.att.xpc.peer[76672].0x7f804828e8a0 bluetoothd Received XPC message "CBMsgIdCheckIn" from session "" bluetoothd Received XPC check-in from session "my_daemon-5555494498236e3b5e2e395b93c13af176769937-peripheral-76672-67" fAccessLevel 0 fProgrammaticPairing 0 fLimitedForMediaAccess 0 bluetoothd Access level is less than kXPCAccessLevelSystem for session "my_daemon-5555494498236e3b5e2e395b93c13af176769937-peripheral-76672-67".

Can anyone definitively say if USBDriverKit is supported on the new OS and 3.2 USB iPhone device? This would be a fantastic way to work with novel devices such as custom cameras. Thanks.
