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!

The battery drains quickly on iPhone SE 3. Whenever I take it off the charger it drains from 100% to 80% in 20 minutes. Please fix this bug?

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!

We have an application that is built for communication for emergency first responders. Our app streams video from emergency responder mobile devices to other responders, however, when the app moves into the background, or the screen locks, the stream is terminated. Is there a way to allow the stream to persist.

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.

我在Core Bluetooth中发现了连接数量相关的错误码：CBError.Code.connectionLimitReached。 但是并没有找到最大连接数量相关的定义。请问在哪里可以找到最大连接数量相关的定义？

I’m encountering an unexpected issue while using NEHotspotConfigurationManager.shared.apply(...) to connect to a Wi-Fi network. Specifically, I’m receiving a userDenied error, even though the user did not interact with any system prompt. Here’s a version of the code I’m using: let config = NEHotspotConfiguration(ssid: ssid, passphrase: passphrase, isWEP: false) // config.joinOnce = true NEHotspotConfigurationManager.shared.apply(config) { error in if let err = error { let nsErr = err as NSError mlog("err.code:\(nsErr.code)") if nsErr.code == NEHotspotConfigurationError.alreadyAssociated.rawValue { self.findWiFiListAndConnect(ssid, passphrase, overtimeSec, timeStart) } else { self.cmdDelegateQueue.async { self.delegate?.wifiClose(nsErr.code) } } } } The error returned is: wifiClose status: 7 Which corresponds to NEHotspotConfigurationError.userDenied. According to the official Apple documentation, this error should only occur when the user explicitly cancels the system dialog. However, in my case: • No system dialog appears. • The user does nothing, yet the error is still returned. • This issue does not happen every time, but it has been observed across multiple devices. Additional info: • iOS version: 18.5 • Device model: iPhone • joinOnce is not set (defaults to false) • Existing configuration is removed using removeConfiguration(...) before applying Is it possible that under certain system states (e.g. backgrounded, network restrictions, or app permissions), iOS silently fails without showing the prompt? Has anyone else encountered this issue, or does anyone know what could cause this behavior? Any help is greatly appreciated!

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?

I need to implement an app that exchanges data with peripherals through TypeC on Apple 15 phones, but I have two questions that I need to ask for help: Which library is used to communicate with peripherals through the TypeC port of the Apple mobile phone? Do peripherals need to pass MFi authentication before they can communicate with the App?

Hello. I am building a BLE device that is Activity Fitness based and would like a "System Level" BLE connection on WatchOS using an ESP32 (I have built a test of this on the firmware side). Meaning I do not want my iOS app to pass the BLE connection to the WatchOS app. It seems like these App Level connections do not get as many background updates as a System Level connection, and also requires the WatchOS app to be launched to connect to the BLE device The System Level BLE connection (WatchOS Settings > BLE > Health Devices) allows for auto connection in the background, and gets more reliable background communication between the BLE device and the Apple Watch On the Apple MFi Page it only mentions iOS: From Apple MFi Page: :: Who does NOT need to join - Developers and manufacturers of accessories that connect to an Apple device using only Bluetooth Low Energy, Core Bluetooth, or standard Bluetooth profiles supported by iOS Does this apply to WatchOS as well? So, if I am making an BLE device that is Activity Based, and has one of the allowable Health Device UUIDs, is the BLE System Connection allowed using any BLE chip? Including say an ESP32 I have built a test BLE firmware that is a Health Device UUID, and the WatchOS sees it as a health device Is this fine then? No need for MFi application and also no need to worry about which BLE chip is used? thanks

We are developing a matter device. How can we display our own APP under the Home device information?

Hi I am implement my app with Core NFC , I found the module have their own UI , can I implement without the UI? we want the NFC scanning in background , not blocking the UI.

I have an accessory with MFi authenticaiton passed(got 0xAA05) and identification accepted (got 0x1D02). But when I try to open the target stream by using iAP2 EA session framework, I always enounter the same error looking like: XPC connection error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.accessories.externalaccessory-server was invalidated from this process." UserInfo={NSDebugDescription=The connection to service named com.apple.accessories.externalaccessory-server was invalidated from this process.} anybody can tell me what it related with? And what can I do to go through it quickly? Thank you much in advance.

Hey everyone, how’s it going? I’d like to know if, by enrolling in Apple’s MFi program, I’ll gain access to develop my own tags and my own app to track them using Apple’s Find network. I also read that there’s an estimated cost of $4 per device—does that apply to each device produced, or only at the time of registering the device, with no fee for additional units?

Dear Sir, I have some questions of IC firmware development of Find My. Any rule request that item must include dual bank feature in IC? I am using Nordic SDK_Connect SDK, Apple has own SDK? If yes, can I download it to use? In Find-My, Apple has service UUID in bluetooth IC? Thank you. Best regards, Sam Ng
