Hello
I've noticed that this product, heavily promoted on the ASC forums for many years, is no longer available from the Apple App Store.
Can anyone tell me the reason why the product is no longer supported?
Friends have asked me if it is 'safe' to use.
Is it?
Note to moderator: If I'm asking in the wrong places, please redirect my question. Thank you.

I am creating a barcode reader using the AVfoundation framework for iOS and IPadOS. The read result goes into payloadstringvalue, but I want to check the control characters contained in the symbol, so I am using the raw data of the description, which is a property of NSObjectProtocol inherited by VNBarcodeObservation. However, I noticed that if the length set in the raw data exceeds 26, some of the raw data in the description is omitted. So my question is, is it possible to set it so that all the raw data in the description is written out without omitting any raw data? If so, could you please tell me how to set this up? Also, if you know of any other way to extract the raw barcode data, I would appreciate it if you could let me know.
Thank you.

Six months ago I wrote FB14122473, detailing how the built-in CDC (or FTDI) VCP serial port driver is limited to 3 Mbps or less. Thing is, there are some FTDI devices that can do 12 Mbps (maybe more), and I have devices I need to communicate with at 4 Mbps. I had to use the FTDI SDK to be able to communicate with these.
I was hoping this post might help draw attention to that bug report.

I have a 4-input, 4-output hardware device and an 8-input, 8-output virtual device, which I combine into an aggregate device. I am using the SimplyCoreAudio library to get the channel count. The code is as follows:
aggregationDevice!.channels(scope: .input) =>> 12 aggregationDevice!.channels(scope: .output) =>> 12
When the program's MicrophoneMode is set to standard, the channel count is correct. However, when I set the MicrophoneMode to voiceIsolation, the channel count is incorrect:
aggregationDevice!.channels(scope: .input) =>> 4 aggregationDevice!.channels(scope: .output) =>> 12
Below is the code for creating the aggregate device:
func createAggregateDevice(mainDevice: AudioDevice,
secondDevice: AudioDevice?,
named name: String,
uid: String) -> AudioDevice?
{
guard let mainDeviceUID = mainDevice.uid else { return nil }
var deviceList: [[String: Any]] = [
[
kAudioSubDeviceUIDKey: mainDeviceUID,
kAudioSubDeviceDriftCompensationKey:1
]
]
// make sure same device isn't added twice
if let secondDeviceUID = secondDevice?.uid, secondDeviceUID != mainDeviceUID {
deviceList.append([
kAudioSubDeviceUIDKey: secondDeviceUID,
kAudioSubDeviceDriftCompensationKey:1,
kAudioSubDeviceInputChannelsKey:8
])
}
let desc: [String: Any] = [
kAudioAggregateDeviceNameKey: name,
kAudioAggregateDeviceUIDKey: uid,
kAudioAggregateDeviceSubDeviceListKey: deviceList,
kAudioAggregateDeviceMainSubDeviceKey: mainDeviceUID,
kAudioAggregateDeviceIsPrivateKey:false,
]
var deviceID: AudioDeviceID = 0
let error = AudioHardwareCreateAggregateDevice(desc as CFDictionary, &deviceID)
guard error == noErr else {
return nil
}
return AudioDevice.lookup(by: deviceID)
}
I hope someone can tell me the reason Thank you!
Currently, we use UIDocumentPickerViewController to read the user's connected sdcard. However, this requires the user to select manually, and the event cannot be monitored.
But recently I found that ImageCaptureCore's ICDeviceBrowserDelegate can monitor the plug-in and unplug events in the didAddDevice callback, but cannot obtain the path of the storage card.
I wonder if there is a way to combine the advantages of both, so that with the user's consent, the card reader events can be monitored and the content can be read directly without the user manually selecting the folder
why is it that this code doesn't show the bluetooth device name but in the iOS settings it is displayed correctly. Thank you.

Current if we use the removeAccessory(_:completionHandler:) method in ASAccessorySession, it removes the accessory from the system and all apps that have previously paired also lose access.
Is there a way to remove the paired accessory only from the app from where the removeAccessory() call is being made? This would be useful in cases where one or more accessories are shared across apps and we need to manage them.
Hi, could you please help on the following points :
Does iOS supports HCE Felica emulation support in Japan?
Does iOS supports Felica card emulation using NFC & SE platform ?
Thanks
We would like to be able to distinguish between iPhones and Apple Watches when scanning for devices using a Laird BLE module.
We know that we can identify an Apple device from the manufacturer data returned in the scan report. 0x004C is the registered identifier for Apple.
In the remaining data returned is it possible identify the device type?
We note that empirically, 4C001005 seems to correlate to an Apple Watch. How reliable is this?
It is useful for us, because it means we do not need to connect to this device to see if it is advertising a service that we own.
Connecting over BLE is of course an expensive operation.
Here is a simple snippet of a Swift App doing a similar thing, to illustrate the question:
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber)
{
guard
let manufData: Data = advertisementData[CBAdvertisementDataManufacturerDataKey] as? Data
else
{
return
}
let hexEncodedManufData: String = manufData.map { String(format: "%02hhx", $0) }.joined()
print("Manufacturer Data: \(hexEncodedManufData): ")
// Manufacturer Data: 4c001007351ff9f9036238: Apple device
// Manufacturer Data: 4c001006331ec0640f88: Apple device
// Manufacturer Data: 4c0010052b18804eb1: Apple watch?
// Manufacturer Data: 4c0010052b18804eb1: Apple watch?

I purchased an iPad Pro M4 in early December, and since day one, I’ve been experiencing a recurring issue. Almost every day, at random times, the device freezes for 1–5 minutes and then restarts itself.
The tablet is not under heavy load when this happens — I mainly use it for light tasks such as watching videos in a player or Safari browser, web surfing, and reading books. The issue has even occurred while the iPad was idle and locked; it froze, displayed the Apple logo, and rebooted.
I brought the device back to the store where I purchased it, and they sent it for a diagnostic check. However, the experts concluded that the device is fully functional, and no defects were found. After one of these crashes, I noticed that my Apple Pencil started lagging (see video file IMG_5688.MOV). However, after another reboot, the issue with the Apple Pencil resolved itself.
I’ve documented the issue with several video recordings showing the freezing and rebooting behavior, as well as error logs generated after such incidents.
Device Details:
Model: iPad Pro M4
Usage: Light tasks only (video streaming, web browsing, reading)
Environment: No overheating, no resource-heavy applications running
What could be causing this issue, and how can I resolve it? Any help would be greatly appreciated. Thank you!
P.S. I’ve uploaded all the device logs and videos demonstrating the issue to Google Drive.

Hello,
I am currently working on a USB HID-class device and I wanted to test communications between various OSes and the device.
I was able to communicate through standard USB with the device on other OSes such as Windows and Linux, through their integrated kernel modules and generic HID drivers. As a last test, I wanted to test macOS as well.
This is my code, running in a Swift-based command line utility:
import Foundation
import CoreHID
let matchingCriteria = HIDDeviceManager.DeviceMatchingCriteria(vendorID: 0x1234, productID: 0x0006) // This is the VID/PID combination that the device is actually listed under
let manager = HIDDeviceManager()
for try await notification in await manager.monitorNotifications(matchingCriteria: [matchingCriteria]) {
switch notification {
case .deviceMatched(let deviceReference):
print("Device Matched!")
guard let client = HIDDeviceClient(deviceReference: deviceReference) else {
fatalError("Unable to create client. Exiting.") // crash on purpose
}
let report = try await client.dispatchGetReportRequest(type: .input)
print("Get report data: [\(report.map { String(format: "%02x", $0) }.joined(separator: " "))]")
case .deviceRemoved(_):
print("A device was removed.")
default:
continue
}
}
The client.dispatchGetReportRequest(...) line always fails, and if I turn the try expression into a force-unwrapped one (try!) then the code, unsurprisingly, crashes.
The line raises a CoreHID.HIDDeviceError.unknown() exception with a seemingly meaningless IOReturn code (last time I tried I got an IOReturn code with the value of -536870211).
The first instinct is to blame my own custom USB device for not working properly, but it doesn't cooperate with with ANY USB device currently connected: not a keyboard (with permissions granted), not a controller, nothing.
I did make sure to enable USB device access in the entitlements (when I tried to run this code in a simple Cocoa app) as well.
...What am I doing wrong here? What does the IOReturn code mean?
Thanks in advance for anybody willing to help out!

Can someone look at this and also i reach to Microsoft and they said that nothing have change on there end.
When are you guys going to fix the CarPlay issues with this new update? I use this for work and it’s really an issue. Nothing is working and it takes up entirely too much space.
Is there any way to use AccessorySetupKit in the background to discover BLE devices?
