Hi, We are developing a Matter switch product. The switch contains 4 buttons, and each button supports click, double click, and held actions. Currently, the device can be successfully commissioned with a HomePod mini, and in the Apple Home app, it is displayed as 4 buttons with options for click, double click, and held for each. The only issue is that the order of the 4 buttons in the Home app does not correspond to the endpoint order (endpoint 1–4). For example, the following mapping might occur: endpoint 1 → button 2 endpoint 2 → button 3 ... We found a related issue on the Apple Developer Forums that matches what we're experiencing: https://developer.apple.com/forums/thread/772367?utm_source=chatgpt.com According to the official response, the problem seems to be caused by insufficient metadata being reported by the device. Could you please provide more specific guidance on what exact information needs to be reported from the device side? We have already tried adding the Fixed Label and User Label clusters to the device, but they don't seem to have any effect. Ideally, we would like the button labels in the Home app add our custom names in the correct order, as below: button 1 (right_button) button 2 (up_button) button 3 (down_button) button 4 (left_button) This would provide a much better user experience. Thank you in advance!

I am writing to report an issue I’m facing after updating my iPhone 11 Pro Max to iOS 26. I have been using the Hollyland Lark M2 external microphone via the Lightning port, and it was working perfectly before the update. However, after upgrading to iOS 26, the iPhone no longer detects it correctly. The device now recognizes the mic as a pair of wired earphones, and it fails to capture any audio input. The microphone itself works flawlessly on other devices, so this appears to be an iOS-specific issue. Could you please confirm: • Whether this is a known issue in iOS 26? • If there are any settings or steps I can take to resolve this? • Whether a fix is planned in an upcoming iOS patch? I would appreciate any guidance or solution you can provide. Thank you for your support.

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?

Macbook pro M4 - will not accept any power adapter after beta update iPhone 16 pro - same exact problem Devices are dead Tried multiple chargers - Watch and IPad appear to be taking a charge for now..

Hello Apple team and community, I’m reporting a critical issue affecting iPhone 13 (128 GB) on iOS 26 Public Beta 3. Problem Summary: • Device stays stuck at 1% battery, even while charging • Battery Health shows 0% in Settings • Phone reboots every 5 minutes while unplugged • Only works when connected to power • Cannot update, charge properly, or maintain uptime Additional Context: • The issue appeared immediately after installing iOS 26 beta 3 • Affected devices often have a replaced battery (even official or high-quality replacements) • Seems to be a software validation bug related to battery firmware • Reported by many users across Reddit, Apple Forums, and Twitter — but not listed in Known Issues What Has Been Tried: • Recovery Mode / Safe charging / Clean install (same version) – no effect • Third-party repair tools (ReiBoot, 3uTools) — partial workaround • Jailbreak with Nugget or iCleaner to disable crash daemons – temporarily helps • Apple Support suggested full device replacement (!) ⸻ Request: Please investigate and acknowledge this issue. This bug renders devices unusable for users with legitimate battery replacements — we need a fix in an upcoming beta.

Hi everyone, while testing HKWorkoutSession with HKLiveWorkoutBuilder on iOS 26 Beta (cycling workout), I noticed the following behavior: – Starting a cycling HKWorkoutSession automatically connects to my Bluetooth heart rate monitor and records HR into HealthKit ✅ – However, my Bluetooth cycling power meter and cadence sensor (standard BLE Cycling Power & CSC services) are not connected automatically, and no data is recorded into HealthKit ❌ On Apple Watch, when starting a cycling workout, these sensors do connect automatically and their data is written to HealthKit — which is exactly what I would expect on iOS as well. Question: Is this by design, or is support for power and cadence sensors planned for iOS in the same way as on watchOS? Or do we, as developers, need to implement the BLE Cycling Power and CSC profiles ourselves (via CoreBluetooth) if we want these metrics? Environment: – iOS 26 Beta – HKWorkoutSession & HKLiveWorkoutBuilder (cycling) – Bluetooth HRM connects automatically – BLE power & cadence sensors do not This feature would make it much easier to develop cycling apps with full HealthKit integration, and also create a more consistent user experience compared to watchOS. Thanks for any insights!

I am working on an app that requires the usage of CoreBluetooth – using both its CBPeripheralManager and CBCentralManager classes. Our app works with other phones and hardware peripherals to exchange data – so we wanted to explore adding AccessorySetupKit to streamline the hardware connection process. AccessorySetupKit has been integrated (while CBPeripheralManager is turned off) and works great, but even with ASK added to our app's plist file and not in use, CBPeripheralManager fails with error: Cannot create a CBPeripheralManager while using AccessorySetupKit framework. Is there any workaround or suggested path forward here? We'd still really like to use ASK while keeping our existing functionality, but are not seeing a clear way to do so.

Hello, I am a developer planning to build an application using Apple's new SpeechTranscriber technology. I am facing an issue where SpeechTranscriber is not available on my iPad Pro (11-inch, 2nd generation, model number: MXDC2J/A), even though I have updated it to iPadOS 26. I was under the impression that SpeechTranscriber would be available on any device running iPadOS 26. Could you please clarify if this is incorrect? Furthermore, I am planning to purchase a new iPad with an A16 chip for the development and deployment of this application. Can you confirm if SpeechTranscriber will be fully functional on an iPad equipped with the A16 chip? Thank you for your assistance.

Prerequisite: After the MDM APP issues the command, the camera on the phone is no longer visible (unusable). After upgrading to iOS 26.1, the isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method keeps returning true when the camera is unavailable. The isSourceTypeAvailable: UIImagePickerControlSourceTypeCamera method on iOS 26.0.1 is normal, returning false when the camera is unavailable and true when it is available.

Problem Description: Since Our USB hubs are capable of sending Vendor Defined Messages (VDMs) over a USB Type-C cable connection, they can programmatically place iOS, iPadOS, and macOS devices into DFU mode—without requiring any physical button interaction. Recently, we identified an issue when invoking DFU mode on an iPhone 15 using this method. Upon entering DFU mode, the device enumerates with USB Product ID 0x1881 (“Debug USB” – KIS interface). At that point, the deviceinterfaced daemon (launched by launchd) immediately detects the device and claims exclusive access to the USB interface. As a result, when our API Service attempts to communicate with the device through standard IOKit methods, it fails with the following error: 0xe00002c5 ((iokit/common) exclusive access and device already open) This prevents our libraries from reading the iBoot string (USB serial number string) that Apple devices normally expose in standard or recovery modes—information that includes ECID, CPID, CPRV, CPFM, BDID, and SCEP. This creates a significant barrier, as our API service becomes unable to perform subsequent device restoration operations as we missed the critical information. Request for Guidance: I’ve included the following context for your analysis and review. Using the launchctl unload command can temporarily stop it; however, I’d like to know if there’s an API-level mechanism to programmatically prevent deviceinterfaced from claiming access from within our API Service. Could you please advise on the following points? 1.  Managing deviceinterfaced Access • What is the proper way to stop or prevent deviceinterfaced from claiming exclusive access in this case, so that the API Service can read device information and starts restoring the device from that point? • Is there a recommended method or entitlement that allows third-party services to communicate with Apple devices while they are in Debug USB (KIS) mode? 2.  Guidelines and API Access • Are there any Apple-supported APIs or developer guidelines that would permit controlled access to the iBoot interface without conflicting with deviceinterfaced?

Hi, we have developed an application that streams data from two BLE peripherals at a rate of 14.5kbps per peripheral. Until now, our devices streamed in near real time with no lag on all Apple devices with Bluetooth 5.0 or greater. Since the release of the iPhone 17 series and the iPad A16, we have reports from users of the data being streamed at significantly lower rates than expected. Any help here would be greatly appreciated as our customers are being affected by this change.

Title iOS App detecting external USB mass storage connection without user interaction Background We are developing an iOS application that connects to an action camera device via Bluetooth and Wi-Fi for control and data transfer. In addition to wireless connectivity, our product requirements include supporting USB Mass Storage mode, where the camera (or a generic USB flash drive) is connected to an iPhone using a Lightning / USB-C adapter and appears in the Files app as an external drive. Requirement Our app needs to detect when an external USB mass storage device is connected or disconnected, with the following constraints: The app is already running in the foreground No user interaction is performed (no button tap, no document picker, no import UI) The USB device can be: A generic USB flash drive An empty USB drive (no photos or videos) The app only needs to know: Whether an external USB storage device has been connected or removed No need to access device identity, vendor info, or low-level USB details The expected behavior is simply to update the app’s internal state or UI when a USB storage device becomes available. Investigation Performed We have already investigated and tested the following public and documented approaches, all of which did not provide a reliable or any notification for USB mass storage insertion: ExternalAccessory / MFi Not applicable for generic USB storage devices Darwin notifications / CoreFoundation Using notify_register_dispatch and CFNotificationCenterGetDarwinNotifyCenter System USB / storage related notifications do not fire for third-party apps File system APIs NSFileManager mountedVolumeURLsIncludingResourceValuesForKeys On iPhone, external USB drives visible in the Files app are not exposed as mounted volumes to third-party apps FileProvider / DocumentPicker Only provides access after explicit user interaction No background or passive notification of availability ImageCaptureCore Limited to PTP camera devices Does not apply to generic USB mass storage Based on our testing, none of the public APIs provide a way to detect USB mass storage insertion automatically without user interaction. Question to Apple We would like to confirm the official platform behavior and capability boundary: Is there any public, documented, App Store–approved API on iOS that allows a third-party app to be notified when a generic USB mass storage device is connected or disconnected, without user interaction? If not: Is this limitation intentional by platform design? Is the recommended approach to rely exclusively on user-initiated document access flows (e.g. document picker, import UI)? Are there any recommended best practices for apps that need to update their UI or internal state based on the availability of external USB storage devices? Our goal is to ensure that our implementation fully complies with iOS platform guidelines and App Store Review requirements. Environment iOS versions tested: iOS 18 (latest public release) Devices: iPhone models with Lightning / USB-C USB devices: generic USB flash drives (including empty drives) Closing We appreciate clarification on whether this capability is intentionally restricted on iOS and how Apple recommends designing user experience around external USB storage access. Thank you for your guidance.

When trying to use the MIDI Maestro app by Singular Sound, BLE peripherals experience unwanted connection-parameter renegotiation and disconnections on iOS 26, beta iOS 26.2 does not fix this issue. iOS 26 BLE communications are being sent too fast to be read correctly by the hardware device, and iOS 26.2 refuses communication altogether.

as i want to tract activity of iphone user using core motion framework , guide me through .

Since 17.4 Dev Beta 2, I have been having Bluetooth issues. I had hoped it would have cleared up but even in 17.4.1 it continues. Airpod and Echo Auto are the only 2 audio devices I have. The audio will become chopping, rubber band or sound robotic and sometime completely disconnect. While driving it will occur on both audio devices. Sometimes I'm stopped at red light and the issue occurs. The phone is less than 3 feet from the device at all times. I have read forums and removed and readded the devices but that did not help. I really do not want to have to reset my phone since my 2FA apps do not recover in a restore. Anyone have any suggestions?

Is it mandatory to use classic Bluetooth (Bluetooth Classic) to connect game controllers that support Apple’s MFi games and Arcade games, or can game controllers be developed using only Bluetooth Low Energy (BLE) for such accessories?

Hello! We currently require the development of an iOS system for encrypting and authorizing photos, videos, voice memos, or other files stored on our devices to a connected USB-C storage. The encrypted files can be accessed through authorization. We have already encrypted and authorized the files to be stored on the app's mobile storage, and cannot directly store them to USB-C (this requirement is based on the Apple camera RroRes, which uses external storage for direct storage). We are seeking technical support from Apple.
