你好，有个问题想请教一下： 我们的app是一款与CGM实时血糖相关的app，app支持在后台通过蓝牙跟CGM血糖设备保持连接。 现在遇到一个问题： 首先，app在后台运行期间，蓝牙是开启状态的，跟CGM设备也是连接的状态。 某个时刻，监听到蓝牙的状态突然从 poweredOn 变为了 resetting ，然后蓝牙又恢复了，状态变为了 poweredOn 这时候，问题出现了：之前连接的那个CGM血糖设备一直无法扫描到了！！ 我想问一下： 什么情况下，蓝牙状态会变为resetting 蓝牙状态恢复为poweredOn后，之前连接的那个CGM血糖设备一直无法扫描到了，为什么？我要怎么做才能恢复，重新扫描到之前连接的这个设备？

My iPhone 16 pro max when on the magnetic charger at home or in my car. My phone just powers down and reboots on its own. This has happened several times a day since updating to iOS 18.4. Anyone else having this problem ?

Today, I submitted the following proposal to Apple through the Feedback Assistant app. I'm not confident in how I phrased it—I'd appreciate any thoughts or feedback from fellow developers. Proposal: "Apple Silicon.app" for macOS with Apple Silicon – Enhancing Performance and Swap Memory Control This suggestion has been machine translated into English, so there may be some discrepancies. If you need the actual text, please feel free to reply to this or ask at the email address below. <mail address> If the author of this proposal is to be credited, I would appreciate being listed under the nickname “DiamondGotCat,” where possible. Summary: - Currently, Apple Silicon-equipped Macs have many system-level features locked down or restricted. - This proposal suggests a new application that enables certain advanced controls for power users. - Tentatively named "Apple Silicon.app", the name may be subject to change if a more suitable alternative arises. - I propose this application be added as a pre-installed utility on compatible systems: macOS (M-series), iPadOS (A-series and M-series), and iOS (iPhones with Apple-designed A5 and newer chips, provided the latest OS is available for them). Overview: This proposal introduces "Apple Silicon.app", a new system-level utility designed to offer power users greater flexibility and control over Apple Silicon behavior, as part of a broader feature update for Apple devices. I propose that Apple Silicon.app be automatically installed as a pre-installed application on Apple Silicon devices (Mac, iPad, iPhone, and select Vision devices) that support upcoming major system updates. Suggested Features of Apple Silicon.app: 1. Performance Core Control To describe this functionality, the following terminology will be used: - P-cores: Performance cores - E-cores: Efficiency cores I understand that Apple Silicon emphasizes energy efficiency, but I believe there are users—myself included—who prioritize maximum performance regardless of power usage. Therefore, I propose that the app offer a drop-down menu with the following six modes for performance core usage: A. Automatic (Recommended) – Default macOS behavior; automatically switches between P/E cores based on workload. B. Performance Priority – Prioritizes P-cores for high-demand tasks, restricts E-cores. Ideal for developers, video editors. C. Power Saving – Uses E-cores only whenever possible; limits P-core usage. Great for battery saving. D. P-Core Exclusive Mode – User-defined processes always run on P-cores. Suitable for benchmarks or low-latency tasks. E. E-Core Exclusive Mode – Prioritizes background tasks and thermal efficiency. F. Manual Assignment (Advanced) – Users can manually assign P/E cores per application in a dedicated settings screen. Additionally, I propose the following optional checkbox settings: - Thermal Safety Mode: Automatically switches from P- to E-cores when system heat exceeds a threshold. - Restore Core Settings on Wake: Remembers P/E settings after sleep/wake. - Power Source Adaptive Mode: Switches to power-saving on battery, and performance mode when plugged in. 2. Swap Memory Configuration The app should also enable user-level control over swap memory (i.e., using part of the SSD as virtual memory). Currently, macOS manages swap space automatically with no user customization available. I propose the ability to manually configure the swap system with the following options: - Enable Manual Configuration: Checkbox to switch from automatic to manual control. - Swap Size: Adjustable in GB units, allowing users to allocate desired swap capacity. 3. Other Settings At this point, these are the core features I propose. If additional useful features exist that align with this concept, I welcome further suggestions or expansion. As users—at least speaking for myself—we look forward to such customization options becoming available.

While compiling nRF5340 target of Dockkit ADK 1.0 following the guide of README.md, I selected the latest Nordic SDK, because there is no specified SDK version in the README.md. But it seems that ADK and SDK are not compatible with each others. For example, it calls nrfx_gpiote_channel_alloc() with one argument in PAL\NCS\HAPPlatformExperience.c. But the difinition of this function needs two arguments. Also I found that in some older version of Nordic SDK, this function needs only one argument. So could you please make sure which version of Nordic SDK should developer use?

Hi, i'm unable to select a icc profile on the new macbook Pro M4. How can i calibrate the internal screen by adding an icc profil made with my X-Rite color calibrator. icc files cannot be selected (grey) from the import menu of the monitor preferences.

We are currently managing our iPhones and iPads using Microsoft Intune and I wanted to get your feedback on other Enterprise management software that gives the admin the ability to manage more granular functions.

I'm device manufacturer and in future planning to get my device matter certified. If I want my device data for analytics purpose into my cloud than what is the best way possible. My research says that the most latest approach suggested by apple is, developing a custom mobile app using device homekit sdk and subscribe to device state and send it to my cloud. If I go that route, will it work even though the device was onboarded via homekit app and homekit hub device is also there. I want to make sure that both path will be active, device to hub to home app and device to custom app to my cloud, and both on matter ecosystem. The homekit sdk and matter support mentioned here https://developer.apple.com/apple-home/matter, are these two same thing?

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.

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.

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

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?

Hi i had problem after upgrade to ios 26. I try connected to my xiaomi earbud bluetooh, all functioning well (watch movie, listen song) except when on call, the bluetooth cannot function at all. Only able speak on phone or loud speaker. Already try do setting at Audio &amp; Visual &gt; Call Audio Routing &gt; Bluetooth Headset. Anyone facing the same issue?

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 opened a terminal window this morning and couldn't cd to /home. When I type a tilde, I get a paragraph symbol. Yesterday, my external keyboard could type a Pipe symbol, no such luck today. I ended up having to use hidutil to remap my keyboard and run keystrokes through terminal to restore what worked yesterday. When I look at the available English keyboards, they're all showing a paragraph symbol above the Tab key. Has anyone else run into this sudden keyboard change?

We have developed a live iOS application, built using Swift and UIKit, that enables users to connect via Bluetooth to an EV charging box. Once connected, users can start and stop the charging process directly from the app. The app also requires an active internet connection initially, as it uses server-side functionality to select and authorize the charging box. However, we recently discovered an issue affecting users on iPhone 14 and iPhone 15 models, specifically when the device enters Satellite mode (Emergency SOS via Satellite) — i.e., when there is no mobile data or Wi-Fi. In this mode, the system Satellite screen is triggered and Bluetooth stops functioning, preventing our app from connecting to the EV box. Users are unable to proceed, even though the app would still be usable via Bluetooth once the box is selected. We have already declared required Bluetooth background modes (bluetooth-central, bluetooth-peripheral) in Info.plist, and the app functions perfectly outside of this scenario. However, the behavior in Satellite mode appears to either disable Bluetooth entirely or restrict access from third-party apps. We’d like to know Is this the expected default behavior on iOS in Satellite mode? Is there any entitlement or exception available to allow Bluetooth access in such emergency scenarios (especially for critical utilities like EV charging)? Can an app like ours be made visible under the Satellite settings, or request access under this mode? This is a concern for users in remote or basement locations where mobile data is unavailable, and they rely solely on Bluetooth to charge their vehicles. Please advise if there is a workaround or planned support in future iOS versions. Thank you.

I'm using AirPods Pro 2 with an iPhone 15 Pro Max. After installing the IOS 26 beta I'm not able to get the new features to work. Does anyone have thoughts or info? Thanks

Immediately after installing iOS 26 on my iPhone 14 Pro, my phone display stopped working. It's not responding to touch, but I can see it charging. It also wakes the screen whenever I pick it up, but it's not touching at all. What do I do, or do I have to downgrade?

I am integrating a camera with HomeKit. The audio and video streams work in the HomeKit Accessory Tester, but they do not work when using the Home app on an iPhone (Failed to select audio config – Could not find the right match in the supported list. Session is not in progress). I have a single audio configuration: Opus 16kHz mono with a constant bitrate of 24kbps.
