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

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
Invalid entitlement for core nfc framework. The sdk version '18.2' and min OS version '14.0' are not compatible for the entitlement 'com.apple.developer.nfc.readersession.formats' because 'NDEF is disallowed'.
Anyone knows what is the correct configuration SDK version and minimum iOS deployment target for NFC that has NDEF format?
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.

Is there any way to use AccessorySetupKit in the background to discover BLE devices?
I'm developing an iPad app and encountered a strange issue with external Bluetooth keyboards.
Issue:
I have a Bluetooth keyboard set to JIS layout in Settings > General > Keyboard > Hardware Keyboard > Keyboard Type.
If I connect the keyboard before launching the app, everything works fine, and the input follows the JIS layout.
However, if I launch the app first and then turn on the Bluetooth keyboard, the input behaves as if the keyboard is in ANSI layout, even though the settings still show JIS.
It seems like iPadOS defaults to ANSI if no external keyboard is connected when the app starts, and later connections do not update the layout properly.
Has anyone encountered a similar issue, and is there a programmatic way to ensure that the correct keyboard layout is applied after the keyboard is connected?
Any help or insights would be greatly appreciated!

Hi,
We’re developing a BLE peripheral device and encountered a connection issue when connecting two devices (Device A and Device B) simultaneously to an iOS device.
Problem:
On iOS 18, we are experiencing occasional BLE timeouts and disconnections when both devices are connected at the same time.
On iOS 16, we did not encounter this issue under the same conditions.
What we’ve tried:
Adjusted the connection interval from 30ms to 15ms.
This seems to have improved stability somewhat.
However, we still observe intermittent timeout/disconnection issues.
Questions:
Are there any known changes in BLE connection handling or timing constraints in iOS 18?
Are there recommended connection parameter settings (interval, latency, timeout, etc.) for multi-device BLE connections in iOS?
Is there a way to debug or log more details about the disconnection reasons on the iOS side?
Any guidance or suggestions would be greatly appreciated.
Hi there,
I am using Core NFC and I established the connection with the card, but after sending the command 'tag.sendCommand()' I receive this message:

We are integrating the Microsoft Web Chat Control inside a WKWebView in our iOS application. The microphone button (used for speech input) works as expected when the app is active. However, we are facing an issue when the app is sent to the background and then brought back to the foreground.
Issue Details:
When the app returns from background to foreground:
🔹 The mic button becomes unresponsive (taps are not recognized).
🔹 No permission prompt or speech functionality is triggered.
🔹 Other elements of the Web Chat control continue to work fine.
This issue seems isolated to iOS and WKWebView usage.
We have verified that microphone permissions are granted and there are no system-level blocks.

I want to get Cover-Art Image over Bluetooth. From the SDP Discover iPhoneSE, it support Cover-Art Feature.
I connect and config OBEX Channel with L2CAP ERTM, it is successful.
I send connect_request the OBEX Connect, the iPhone always no any response, and l2cap s-frame response from iPhone always failed.
From the Apple Developer, it need Apple Authentication Chip.
Is it still necessary now? Are there any other ways to obtain album pictures?
Hey, I need to know how to use texture mapping for rendering a spectrogram in metal. As I need smoothens the spectrogram. In my current project I am using vertex based approach which results in blocky behaviour between each quad. I need to smooth across each qaud so that It will smoothly gradient over.
Hello,
I recently installed the macOS 26 beta version on my MacBook Air M3, and I've encountered an issue where edited Word files are failing to save. I’ve tried restarting my laptop and checking for updates, but the problem persists.
Has anyone else experienced this issue? Is there a specific setting I might have missed or any troubleshooting steps you recommend?
Thank you for your assistance!

Recently I got an issue on App Store that my build got rejected because of iPad Air 5. My app include Device binding which means sim should be present in Device while using the app, where as, I mad the app mainly for iPhone not for pads. But AppStore is rejecting my build saying getting no sim issue in iPad Air 5th gen And os 18.5 . So what should I do? Which device I should prefer so that I can use it future also , should not be outdated within some time.

Hi there!
I'm developing a dual-mode bluetooth accessory and would like to pair it through AccessorySetupKit. I'm using an ESP32 with Bluekitchen btstack. This supports CTKD, which seems to be a requirement for the Bluetooth transport bridging according the WWDC19 session 901. I've been in contact with the btstack developer and verified that I can get the device to generate an LTK for the classic transport when reading an encrypted attribute. I'm not able to get this to work with the bluetoothTransportBriding option with AccessorySetupKit though.
What I've found so far is that if I omit the .bluetoothTransportBriding option during pairing I will get a pairing request when I read an encrypted attribute after connecting with the CBConnectPeripheralOptionEnableTransportBridgingKey option. If I accept this request it seems like the system automatically brings up the A2DP profile.
However if I include .bluetoothTransportBriding and/or .bluetoothPairingLE this option does not pop up, but the system does not bring up the A2DP profile. In this case things seem to end up in a weird situation where the device doesn't show up for pairing in Bluetooth Settings either, making it impossible to manually connect for A2DP.
Based on the AccessorySetupKit example from WWDC24 I've created a dice accessory firmware for ESP32 using btstack. The code for this is available here: https://github.com/ljodal/esp32-btstack-ctkd-test
I've also tweaked the AccessorySetupKit example app for iOS to add the ASAccessory.SupportOptions. The code for that is available here: https://github.com/ljodal/accessorysetupkit-ctkd-test
Is there any documentation available anywhere on what is expected of the device for Bluetooth Transport Bridging to work with AccessorySetupKit?

first post here and this is kinda a long shot. I’m working on a custom keypad project for a young man with some mobility issues that unfortunately prevents gestrue and voice control as UI options.
id like to see if I can pull track metadata via a Bluetooth connection into a custom keyboard with a small screen.
I know hid doesn’t support this but I was hoping maybe the API for iOS’s blueprint remote app could be leveraged.
I haven’t don’t much with Apple previousl. Usually Roku and Crestron implantations but I’m hoping to see if I can accomplish something with Apple, without needing to implement any IP connection.

Our app is connected to a hardware wifi without network. Under normal circumstances, we can communicate with the device. At some point, the communication suddenly stops, and the ping prompts "No route to host". The only way to reconnect is to restart the device. It feels like the system has marked ARP. Is there any way to reconnect the device without restarting the iphone?

On the iPad Pro 12.9-inch (3rd generation) cellular model, when you touch the screen with four fingers and then move your fingers, the touch is no longer detected. The same operation with one to three fingers works normally.
This phenomenon does not occur when accessibility is turned on.
Is this a beta-specific issue that will be fixed in the official release?
