Hi, I want to create a ControlWidget button that acts as a shortcut in the control center open a specific view within my app to show a badge. Problem: I can‘t get it to open my host app. I tried a custom myapp:// protocol - did not work, I tied AppIntent with the openAppWhenRun set to true - did not work and the strange thing is the debugger breakpoint in perform will only get triggered if this is set to false. OpenIntent did not work either even if I use a dummy swift app as host to try it out. What is the current supported way (iOS 18 and 26) to open your app when a static ControlWidget button is clicked, what could I have done wrong / am missing?

I am writing a DriverKit driver for the first that uses the USBSerialDriverKit. The driver its purpose is to expose the device as serial interface (/dev/cu.tetra-pei0 or something like this). My problem: I don't see any logs from that driver in the console and I tried like 40 different approaches and checked everything. The last message I see is that the driver get successfully added to the system it is in the list of active and enabled system driver extensions but when I plug the device in none of my logs appear and it doesn't show up in ioreg. So without my driver the target device looks like this: +-o TETRA PEI interface@02120000 <class IOUSBHostDevice, id 0x10000297d, registered, matched, active, busy 0 (13 ms), retain 30> | { | "sessionID" = 268696051410 | "USBSpeed" = 3 | "UsbLinkSpeed" = 480000000 | "idProduct" = 36886 | "iManufacturer" = 1 | "bDeviceClass" = 0 | "IOPowerManagement" = {"PowerOverrideOn"=Yes,"DevicePowerState"=2,"CurrentPowerState"=2,"CapabilityFlags"=32768,"MaxPowerState"=2,"DriverPowerState"=0} | "bcdDevice" = 9238 | "bMaxPacketSize0" = 64 | "iProduct" = 2 | "iSerialNumber" = 0 | "bNumConfigurations" = 1 | "UsbDeviceSignature" = <ad0c16901624000000ff0000> | "USB Product Name" = "TETRA PEI interface" | "locationID" = 34734080 | "bDeviceSubClass" = 0 | "bcdUSB" = 512 | "USB Address" = 6 | "kUSBCurrentConfiguration" = 1 | "IOCFPlugInTypes" = {"9dc7b780-9ec0-11d4-a54f-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "UsbPowerSinkAllocation" = 500 | "bDeviceProtocol" = 0 | "USBPortType" = 0 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "USB Vendor Name" = "Motorola Solutions, Inc." | "Device Speed" = 2 | "idVendor" = 3245 | "kUSBProductString" = "TETRA PEI interface" | "kUSBAddress" = 6 | "kUSBVendorString" = "Motorola Solutions, Inc." | } | +-o AppleUSBHostCompositeDevice <class AppleUSBHostCompositeDevice, id 0x100002982, !registered, !matched, active, busy 0, retain 5> | { | "IOProbeScore" = 50000 | "CFBundleIdentifier" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOProviderClass" = "IOUSBHostDevice" | "IOClass" = "AppleUSBHostCompositeDevice" | "IOPersonalityPublisher" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "bDeviceSubClass" = 0 | "CFBundleIdentifierKernel" = "com.apple.driver.usb.AppleUSBHostCompositeDevice" | "IOMatchedAtBoot" = Yes | "IOMatchCategory" = "IODefaultMatchCategory" | "IOPrimaryDriverTerminateOptions" = Yes | "bDeviceClass" = 0 | } | +-o lghub_agent <class AppleUSBHostDeviceUserClient, id 0x100002983, !registered, !matched, active, busy 0, retain 7> | { | "IOUserClientCreator" = "pid 1438, lghub_agent" | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@0 <class IOUSBHostInterface, id 0x100002986, registered, matched, active, busy 0 (5 ms), retain 9> | | { | | "USBPortType" = 0 | | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | | "USB Vendor Name" = "Motorola Solutions, Inc." | | "bcdDevice" = 9238 | | "USBSpeed" = 3 | | "idProduct" = 36886 | | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | | "bInterfaceSubClass" = 0 | | "bConfigurationValue" = 1 | | "locationID" = 34734080 | | "USB Product Name" = "TETRA PEI interface" | | "bInterfaceProtocol" = 0 | | "iInterface" = 0 | | "bAlternateSetting" = 0 | | "idVendor" = 3245 | | "bInterfaceNumber" = 0 | | "bInterfaceClass" = 255 | | "bNumEndpoints" = 2 | | } | | | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x100002988, !registered, !matched, active, busy 0, retain 6> | { | "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} | "IOUserClientCreator" = "pid 1438, lghub_agent" | "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} | "IOUserClientDefaultLocking" = Yes | } | +-o IOUSBHostInterface@1 <class IOUSBHostInterface, id 0x100002987, registered, matched, active, busy 0 (5 ms), retain 9> | { | "USBPortType" = 0 | "IOCFPlugInTypes" = {"2d9786c6-9ef3-11d4-ad51-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"} | "USB Vendor Name" = "Motorola Solutions, Inc." | "bcdDevice" = 9238 | "USBSpeed" = 3 | "idProduct" = 36886 | "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb")) | "bInterfaceSubClass" = 0 | "bConfigurationValue" = 1 | "locationID" = 34734080 | "USB Product Name" = "TETRA PEI interface" | "bInterfaceProtocol" = 0 | "iInterface" = 0 | "bAlternateSetting" = 0 | "idVendor" = 3245 | "bInterfaceNumber" = 1 | "bInterfaceClass" = 255 | "bNumEndpoints" = 2 | } | +-o lghub_agent <class AppleUSBHostInterfaceUserClient, id 0x10000298a, !registered, !matched, active, busy 0, retain 6> { "UsbUserClientBufferStatistics" = {"IOMemoryDescriptor"=0,"IOBufferMemoryDescriptor"=0,"IOSubMemoryDescriptor"=0} "IOUserClientCreator" = "pid 1438, lghub_agent" "UsbUserClientBufferAllocations" = {"Bytes"=0,"Descriptors"=0} "IOUserClientDefaultLocking" = Yes } more details in my comment.

I have a driver extending IOUserUSBSerial and I want the device to show up as /dev/tty.mycustombasename-123 and /dev/cu. respectively. How can I achieve that?

Hi Devs, i have a question concerning the security set-key-partition-list -S command. I want to use it to enable a code signing certificate being used by codesign and productbuild to sign without sudo or a password prompt. Some sources indicate i need to add codesign: as partition but some don't even mention this. So my question is what partitions are even possible to add? What does partitions in this context mean? How can i find out which i need for productbuild and codesign? Thanks in advance Paul

Is there a possibility to enable the public transport layer like in the Maps app?

I recently encountered a "potential bug" with SwiftData. I save my model with modelContent.insert and after that I get following error when trying to delete it with modelContent.delete: Could not cast value of type 'Swift.Optional<Any>' (0x1f5b871f8) to 'Foundation.UUID' This I mentioning the let id: UUID field marked with @Attribute(.unique). This build doesn't crash running in an iOS Sim but if it's running thought TestFlight on my iPhone it just crashes. If I try to delete elements that aren't just created, I don't get this error.

I found out that you can define a launch-screen image for WebApps on IOS. Now I have a question: Is it possible to define different launch screen images based on the different rotations and screen sizes?
