I'm building a React Native call application using the following combination of libraries: https://github.com/react-native-webrtc/react-native-callkeep https://github.com/react-native-webrtc/react-native-webrtc https://github.com/react-native-webrtc/react-native-voip-push-notification When I press the speaker button on the call screen displayed by CallKit and change it to ON, the speaker button display on the call screen reverts back to OFF after a few seconds. However, when the speaker button display reverts to OFF, the actual audio output route does not return to the earpiece - the audio continues to output from the speaker without any change. Could you please advise on what cases might cause the speaker button display to revert, and if there are any potential solutions?

[sysdiagnose_2025.10.01_18-29-27+0800_iPhone-OS_iPhone_23A341] I got sysdiagnose from my app user.He can't pair his bluetooth peripheral. in the sysdiagnose,I found this: device AC:7A:94:85:47:F4 is already paired, with a different irk (old:F5 C9 4F 5A 4E BE D0 20 0A 1F F7 DC 3A 89 E0 3A new 4A 8A 00 4C FF D0 CE 7B 61 13 FA B3 84 F4 65 29 ).

I don't know how to delete the irk info when you can't find it in SYSTEM BLUETOOTH PREPHERAL LIST. PLEASE answer me. THANKS.

Hi everyone — I’m developing an iOS passkey/password manager where the private key material must be stored on a physical device (NFC card / USB token). I’m hitting a hard limitation: CoreNFC is not available for use from app extensions, which prevents an appex (e.g. password/credential provider or other extension) from talking directly to an NFC card during an authentication flow.  My questions: 1. Is there any plan to make CoreNFC (or some limited NFC-API) available to app extensions in a future iOS version? If not, could Apple clarify why (security/entitlements/architecture reasons)? 2. Are there any recommended/approved workarounds for a passkey manager extension that needs to access a physical NFC token during authentication? (For example: background tag reading that launches the containing app, or some entitlement for secure NFC card sessions.) I’ve read about background tag reading, but that seems to be about system/OS handling of tags rather than giving extensions direct NFC access.  3. Is the only supported pattern for my use case to have the containing app perform NFC operations and then share secrets with the extension via App Groups / Keychain Sharing / custom URL flow? (I’m already evaluating App Groups / Keychain access groups for secure sharing, but I’d like official guidance.)  Implementation details that may help responders: • Target: iOS (latest SDK), building a Credential Provider / password manager extension (appex). • Intended physical token: NFC smartcard / ISO7816 contactless (so CoreNFC APIs like NFCISO7816Tag would be ideal). • Security goals: private key never leaves the physical token; extension should be able to trigger/sign during a browser/app AutoFill flow. Possible alternatives I’m considering (open to feedback): designing the UX so that the extension opens the main app (only possible for Today widget in a supported way) which runs the NFC flow and stores/returns a short-lived assertion to the extension. Are any of these patterns sanctioned / recommended by Apple for credential providers?  Thanks — any pointers to docs, entitlement names, or example apps/samples would be extremely helpful.

Since I updated my iPhone 13 to this new update I have two problems First: the battery discharges too fast or it gets stuck and doesn't discharge until I turn it off and turn it back on. Second: I see in my screen time a page that I had never seen is called imasdk.googleapis.com which I had never occupied and they tell me that it is a failure of the new update I hope you can help me fix that, since this mobile phone is new and already brings the faults by the ios

Device: iPhone [model], iOS 18.6.2 Xcode: 16.0.x Team: Individual paid Apple Developer Program (not Personal Team), shows as my full name in Xcode I’m trying to use CoreNFC via NFCTagReaderSession in a small SwiftUI app (part of a larger project). So far I’ve done: • Enrolled in the Apple Developer Program (individual). • Confirmed that in Certificates, Identifiers & Profiles → Identifiers, my App ID for com.<…> has Near Field Communication Tag Reading enabled. • Created an iOS App Development provisioning profile for that App ID, including: • my Apple Development certificate • my iPhone device • Downloaded the profile, double-clicked it, and set it in Xcode under Signing & Capabilities with: • Team = my full-name team • “Automatically manage signing” off, using the custom profile. • Added the NFC Scan capability in Signing & Capabilities. • Added Privacy - NFC Scan Usage Description (NFCReaderUsageDescription) in Info.plist with a non-empty string. The app builds and runs on device. When I start the session: func beginScanning() { print("NFCTagReaderSession.readingAvailable =", NFCTagReaderSession.readingAvailable) session = NFCTagReaderSession(pollingOption: [.iso14443, .iso15693], delegate: self, queue: nil) session?.alertMessage = "Hold your iPhone near your Ori tag." session?.begin() } func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) { print("NFC session invalidated:", error.localizedDescription) } readingAvailable is false, and I immediately see: NFC session invalidated: Session invalidated unexpectedly Earlier in this process I was seeing XPC sandbox messages like: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.nfcd.service.corenfc was invalidated: failed at lookup with error 159 - Sandbox restriction." Those went away after I created the explicit iOS App Development profile and pointed the target at it, but the session still invalidates right away and readingAvailable never becomes true. Safari can read NDEF URL tags on this device, so the NFC hardware is working. Question: Is there anything else required on the App ID / provisioning / team side to enable CoreNFC with NFCTagReaderSession for an individual (non-enterprise) developer account? Or any known issues where readingAvailable stays false even with NFC Tag Reading enabled and a custom iOS App Development profile? Any hints on what I might still be missing would be greatly appreciated.

I have poked around the web looking for a good example to do this and I haven't found a working example. I need to connect to a USB Device, its multiple ports and supports what looks to be a root port and 4 other ports I am no expert in USB but I do know how to write a kext and client drivers, but thats really not the way to solve this. I need to display the serialized output from these USB ports for a development board. I would rather do this on my Mac than have to cobble up a Linux machine and mess around with Linux. Here is the output from ioreg MCHP-Debug@03100000 <class IOUSBHostDevice, id 0x105f6fdc2, registered, matched, active, busy 0 (20 ms), retain 27> MCHP-Debug@0 <class IOUSBHostInterface, id 0x105f6fdc8, registered, matched, active, busy 0 (13 ms), retain 5> +-o MCHP-Debug@0 <class IOUSBHostInterface, id 0x105f6fdc8, registered, matched, active, busy 0 (13 ms), retain 5> +-o MCHP-Debug@1 <class IOUSBHostInterface, id 0x105f6fdc9, registered, matched, active, busy 0 (11 ms), retain 5> +-o MCHP-Debug@2 <class IOUSBHostInterface, id 0x105f6fdcb, registered, matched, active, busy 0 (9 ms), retain 5> | | | | | +-o MCHP-Debug@3 <class IOUSBHostInterface, id 0x105f6fdcc, registered, matched, active, busy 0 (7 ms), retain 5> I have been able to open a inservice to the device at the top level, but I get an error when I use. usbHostInterface = [[IOUSBHostInterface alloc] initWithIOService:usbDevice options: IOUSBHostObjectInitOptionsNone queue: queue error: &error interestHandler: handler]; Error:Failed to create IOUSBHostInterface. with reason: Unable to obtain configuration descriptor. Assertion failed: (usbHostInterface), function main, file main.m, line 87. I started using DeviceKit but I received signing errors and I shouldn't have to go down that path just to dump data from a USB port? Any suggestions would be great, most of the Apple documentation on USB ports is like 20 years old and the new stuff pushes you towards DeviceKit.

iOS 26.2 Beta 23C5044b Phone's battery reports 0% Health, leaving it on multiple chargers (high/low wattage) doesn't change anything. Icon changes to charging. Changed the battery with a high quality aftermarket of ~70% charge, same issue. Unable to remove beta or update to RC2 due to the 20% minimum required... not sure what to do.

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.

Hello, We are developing an iAP2 accessory and encountering an issue during the Identification phase. Issue: Authentication: ✅ Successful Identification: ❌ IdentificationInformation rejected (0x1D03) Product Plan Status: "Submitted" (in MFi Portal) What we've verified: ProductPlanUID matches MFi Portal All required parameters per R43 Table 101-9 are included Parameters are in ascending order by ID Message format appears correct Observation: iPhone accepts the message format but still rejects IdentificationInformation, suggesting the issue may be related to Product Plan configuration or status rather than parameter format. Questions: Can a Product Plan with status "Submitted" complete iAP2 identification, or does it need to be "Approved"? Are there any Product Plan configuration requirements that might not be visible in MFi Portal? Should we configure "Control Message Lists" in Product Plan? (We don't see this option in Portal) We can provide additional technical details through secure channels if needed. Thank you for your assistance.

Hi, We are facing the issue of commissioning our Matter device to google home through iOS device will be 100% failed. Here is our test summary regarding the issue: TestCase1 [OK]: Commissioning our Matter 1.4.0 device to Google Nest Hub 2 by Android device (see log DoorWindow_2.0.1_Google_Success.txt ) TestCase2 [NG]: Commissioning Matter 1.4.0 device to Google Nest Hub 2 by iPhone13 or iPhone16 (see log DoorWindow_2.0.1_Google_by_iOS_NG.txt ) TestCase3 [OK]: Commissioning our Matter 1.3.0 device to Google Nest Hub 2 by iPhone13 In TestCase2, we noticed that device was first commissioned to iOS(Apple keychain) then iOS opened a commissioning window again to commission it in Google’s ecosystem, and the device was failed at above step 2, so we also tried: Commissioning the device to Apple Home works as expected, next share the device to Google Home app on iOS, this also fails. Commissioning the device to Apple Home works as expected, next share the device to Google Home app on Android, this works as expected and device pops up in Google home of iOS as well. Could you help check what's the issue of TestCase2? Append the environment of our testing: NestHub 2 version Google Home APP version

Hi, I’m developing a Matter commissioning flow and would like to clarify Apple Home’s support for concatenated (multi-device) QR codes. In my implementation, I generate a single QR code that contains multiple Matter onboarding payloads (concatenated payloads), intended to commission multiple devices in one scan, similar to a multi-pack / multi-accessory flow. What I’ve tested: Standard single-device Matter QR codes work as expected in the Apple Home app A concatenated QR code (multiple Matter payloads combined into one QR) does not get recognized / commissioned by Apple Home My questions: Does Apple Home officially support commissioning via concatenated or multi-device Matter QR codes? If yes, is there a specific payload format or delimiter that Apple Home expects? If not, is this a known limitation or something planned for future iOS/Home releases?

Hello everyone, I am developing an iOS application that relies on accelerometer data for precise motion and reaction-time measurements. Based on practical testing, it appears that third-party iOS applications receive accelerometer data at a maximum rate of approximately 100 Hz, regardless of hardware capabilities or requested update intervals. I would like to ask for clarification on the following points: Is there an officially supported way for third-party iOS apps to access accelerometer data at sampling rates higher than ~100 Hz? If the hardware supports higher sampling rates, is this limitation intentionally enforced at the iOS level for third-party applications? Are there any public APIs, entitlements, or documented approaches that allow access to higher-frequency sensor data, or is this restricted to system/internal components only? Thank you in advance for any clarification.

I followed the instructions on the page https://mfi.apple.com/en/help/login-help/How-to-Register-Your-Existing-Apple-ID.html to apply for the MFi Program. According to step 7 of the guide: "You have now created and registered your Apple Account. You will be automatically directed to the MFi Portal to begin the enrollment process," I should have been taken to the enrollment process after logging in. However, instead of accessing the enrollment page, a pop-up message appears stating: "The Apple Account you signed in with does not have permission to view this page. If you believe your company is currently enrolled in the MFi Program, please contact your company’s Account Administrator to request access to the MFi Portal. If your company is not currently enrolled in the MFi Program, please click here to learn about the program and start the enrollment process." This has created an endless loop—I cannot proceed to the enrollment process as instructed, and the pop-up only redirects me to information that leads back to the same login and permission issue. Could you please provide guidance on how to resolve this and successfully access the MFi Program enrollment process?

Summary On Mac Studio systems (no built-in camera), macOS does not initialize camera services after a normal reboot if no physical camera is present. As a result, Continuity Camera does not appear anywhere in the system. Observed behavior System Information → Camera reports “No video capture devices were found.” Continuity Camera (iPhone) is completely absent from camera lists. Plugging in any USB UVC webcam immediately initializes camera services and causes both the USB camera and the iPhone (Continuity Camera) to appear. The USB camera can then be unplugged and Continuity Camera continues working until the next reboot. Reproduction steps Use a Mac Studio (no built-in camera) on recent macOS. Ensure no USB webcam or external camera is connected. Reboot the Mac normally. After login, open System Information → Camera. Expected Camera services should initialize even when no physical camera is present, allowing Continuity Camera to be available as the primary camera. Actual No camera devices are present unless a physical USB camera is connected at least once after boot. This reproduces 100% of the time on Mac Studio and appears to be a camera service bootstrap issue where Continuity Camera cannot be the first camera device. Issue has been filed via Feedback Assistant.

Hi everyone, We are currently exploring ways to implement a frictionless Wi-Fi setup for our hardware devices without requiring a dedicated third-party application. We are interested in leveraging Apple's WAC (Wireless Accessory Configuration) to sync Wi-Fi credentials directly from iOS devices. However, we have struggled to find comprehensive technical documentation or specifications regarding the WAC service. Could anyone point us to the official source for these materials? Additionally, we have a couple of technical questions: 1.We are testing WAC provisioning and found that the Home app can discover our device and successfully get it online. However, it always ends with a "Failed to add accessory" message. Does WAC support imply that a device should be addable via the Home app? If not, why is the Home app able to discover and start the setup for a non-HomeKit WAC device? 2. Our device is already Apple AirPlay certified. Does implementing WAC require additional standalone certification, or is it covered under the existing MFi/AirPlay certification umbrella? Any insights or guidance would be greatly appreciated. Thank you!

Hello, I am a Bluetooth Engineer at Google investigating an interoperability bug between an Android device and AirPods 4. When requesting an L2CAP connection (with PSM = AVDTP) to the AirPods during SDP service discovery, The AirPods L2CAP layer incorrectly responds with a "refused - no resources available" status followed by a Pending status and a Success status. This violates the specification, which says that the request has been fully rejected after the refused status and should not receive followup responses. I suspect the "no resources available" response is a bug. This prevents A2DP from working with the AirPods. This bug does not exist with AirPods 2 firmware. Here is a packet capture: 1602 1969-12-31 16:07:04.805261 0.062473 localhost () Apple_6b:db:09 (AirPods) L2CAP 17 Sent Connection Request (AVDTP, SCID: 0x22c6) 1603 1969-12-31 16:07:04.810953 0.005692 controller host HCI_EVT 8 Rcvd Number of Completed Packets 1604 1969-12-31 16:07:04.811078 0.000125 Apple_6b:db:09 (AirPods) localhost () SDP 27 Rcvd Service Search Attribute Request : Device Information: [Bluetooth Profile Descriptor List 0x0009] 1605 1969-12-31 16:07:04.821249 0.010171 localhost () Apple_6b:db:09 (AirPods) SDP 19 Sent Service Search Attribute Response 1606 1969-12-31 16:07:04.876396 0.055147 controller host HCI_EVT 8 Rcvd Number of Completed Packets 1607 1969-12-31 16:07:04.876464 0.000068 Apple_6b:db:09 (AirPods) localhost () L2CAP 21 Rcvd Connection Response - Refused - no resources available (SCID: 0x22c6) 1608 1969-12-31 16:07:04.942539 0.066075 Apple_6b:db:09 (AirPods) localhost () SDP 41 Rcvd Service Search Attribute Request : Unknown: [Bluetooth Profile Descriptor List 0x0009] 1609 1969-12-31 16:07:04.951052 0.008513 localhost () Apple_6b:db:09 (AirPods) SDP 19 Sent Service Search Attribute Response 1610 1969-12-31 16:07:05.010605 0.059553 controller host HCI_EVT 8 Rcvd Number of Completed Packets 1611 1969-12-31 16:07:05.080593 0.069988 Apple_6b:db:09 (AirPods) localhost () SDP 27 Rcvd Service Search Attribute Request : GATT: [Bluetooth Profile Descriptor List 0x0009] 1612 1969-12-31 16:07:05.087636 0.007043 localhost () Apple_6b:db:09 (AirPods) SDP 19 Sent Service Search Attribute Response 1613 1969-12-31 16:07:05.209417 0.121781 controller host HCI_EVT 8 Rcvd Number of Completed Packets 1614 1969-12-31 16:07:05.279491 0.070074 Apple_6b:db:09 (AirPods) localhost () L2CAP 21 Rcvd Connection Response - Pending (SCID: 0x22c6) 1615 1969-12-31 16:07:05.280731 0.001240 Apple_6b:db:09 (AirPods) localhost () L2CAP 21 Rcvd Connection Response - Success (SCID: 0x22c6, DCID: 0x0406) Please file this bug with the AirPods Bluetooth team.

Hello Apple Developer Technical Support Team, I’m working on an iOS banking/security SDK and we’re trying to match an Android feature that reads payment cards via NFC (EMV). On Android, this is implemented using an NFC scanning screen (e.g., “NfcScanActivity”) that can read EMV data from contactless credit/debit cards. Could you please clarify the current iOS capabilities and App Store policy around this? On iOS, is it currently possible for a third-party App Store app to read contactless credit/debit cards using Core NFC (i.e., accessing EMV application data/AIDs from payment cards)? If this is possible, what are the supported APIs/frameworks and any entitlement requirements (if applicable)? If this is not possible for App Store apps, could you recommend the closest acceptable alternatives for achieving a similar user outcome? For example: Using Apple Pay / PassKit flows for payment-related experiences Card scanning alternatives (camera-based OCR) for capturing card details (if allowed) Using an external certified card reader accessory (MFi) and required approach/entitlements Any other Apple-recommended approach for “card verification / identification” without reading EMV NFC data Our goal is not to bypass security restrictions, but to provide a compliant solution on iOS comparable to Android’s NFC-based card reading, or to adopt an Apple-approved alternative if direct EMV reading is not supported. If helpful, I can share a brief technical summary of the Android behavior and the exact data we need to obtain (e.g., whether it’s card presence verification vs. reading specific EMV tags). Thank you for your guidance. Best regards, Anis

EASession(accessory:forProtocol:) always returns nil — MFI accessory iAP2 Platform: iOS 17+ | Hardware: Custom MFI-certified accessory (USB-C, iAP2) | Language: Swift Problem We have a custom MFI-certified accessory communicating over USB-C using ExternalAccessory. The app calls EASession(accessory:forProtocol:) after receiving EAAccessoryDidConnect but it always returns nil. We never get past session creation. What we have verified We captured a sysdiagnose on-device and analysed the accessoryd-packets log. The full iAP2 handshake completes successfully at the OS level: USB attach succeeds MFI auth certificate is present and Apple-issued Auth challenge and response complete successfully IdentificationInformation is accepted by iOS — protocol string and Team ID are correct EAAccessoryDidConnect fires as expected iOS sends StartExternalAccessoryProtocolSession — the OS-level session is established So the hardware, MFI auth, protocol string, and Team ID are all correct. Despite this, EASession(accessory:forProtocol:) returns nil in the app. We also confirmed: Protocol string in UISupportedExternalAccessoryProtocols in Info.plist matches the accessory exactly Protocol string in code matches Info.plist App entitlements are correctly configured EAAccessoryManager.shared().registerForLocalNotifications() is called before connection Current connection code @objc private func accessoryDidConnect(_ notification: Notification) { guard let accessory = notification.userInfo?[EAAccessoryKey] as? EAAccessory else { return } DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) { self.tryConnectToAccessory() } } private func tryConnectToAccessory() { DispatchQueue.main.asyncAfter(deadline: .now() + 3.0) { for accessory in EAAccessoryManager.shared().connectedAccessories { let session = EASession(accessory: accessory, forProtocol: "") // session is always nil here } } } Questions The packet log shows a ~4 second gap between EAAccessoryDidConnect firing and iOS internally completing session readiness (StartExternalAccessoryProtocolSession). Is there a reliable way to know when iOS Is it actually ready to grant an EASession, rather than using a fixed delay? Is there a delegate callback or notification that fires when the accessory protocol session is ready to be opened, rather than relying on EAAccessoryDidConnect + an arbitrary delay? Are there any known conditions on iOS 17+ under which EASession returns nil even though the iAP2 handshake completed successfully at the OS level? Is retrying EASession after a nil result a supported pattern, or does a nil result mean the session will never succeed for that connection? Any guidance appreciated.
