After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen. This currently works with older versions of Xcode with the same app on the same iPad. This worked with older versions of Xcode on the same MacBook as well (including the Xcode 26 beta before updating to the official release yesterday) The specified file could not be transferred.

Right now, I am scanning for specific BLE peripherals with my iPad app, using this: [self.cbCentralManager scanForPeripheralsWithServices:serviceUUIDsToScanFor options:@{CBCentralManagerScanOptionAllowDuplicatesKey:@YES}]; I have the "CBCentralManagerScanOptionAllowDuplicatesKey" set true because I need to be able to detect when a peripheral is no longer advertising, so I capture each "didDiscoverPeripheral" callback and set a 3-second timer that notifies the user that that peripheral is no longer in range if another didDiscoverPeripheral hasn't been received in that time. The peripherals all advertise at 100ms intervals. What's weird is that if I leave the scan on for a long time, the advertising packets slow down, and eventually one of those timers times out, around about one or two minutes for the first instance, and then every 10-20 seconds after that. I've checked with ATS for all the BLE traffic, and there are indeed > 3-second gaps in the advertising packets that the iPad sees, so it's not my code introducing the gap. Is there some reason long-running scans should not be done on iPadOS (both 18 and 26.1 used)? I've tested out switching my scan to "stopScan" and restart it every 10 seconds, and that seems to have resolved the issue, but it's unclear why that would matter (and that does not seem like an appropriate use of the stop and start scans). Thanks!

I am trying to open the CommunicationControl class IOUSBHostInterface in my USB driver, but it only seems to open on iPad Airs and not iPad Pros. I'm calling ivars->interruptInterface->Open(this, 0, NULL); After retrieving the interruptInterface from the device's InterfaceIterator. I try and open this, but on iPad Pros it returns kIOReturnNotOpen. I've tried closing and reopening the IOUSBHostDevice, closing and reopening the Interface, AbortDeviceRequests before opening, etc. but it just seems to work on iPad Air and not iPad Pro. I've tried on both iPadOS 17.6.1 and 18.2 Has anyone else seen this?

I'm trying to copy a DriverKit project's dext output after building it, but it's not getting signed in the DerivedData until after the copy to my location. I've tried to select the "Code Sign On Copy" option in the Copy Files steps, but the checkbox is just not there (there's some kind of text box there instead that doesn't take any text?). It works for every other Copy Files selection; it only doesn't work for drivers. I've also tried adding the CodeSignOnCopy attribute to the .dext product in the xcode project's Copy Files step manually without using the Xcode UI, but that doesn't do anything either. Is there a way to set this attribute or otherwise mimic its functionality?
