Hello I've noticed that this product, heavily promoted on the ASC forums for many years, is no longer available from the Apple App Store. Can anyone tell me the reason why the product is no longer supported? Friends have asked me if it is 'safe' to use. Is it? Note to moderator: If I'm asking in the wrong places, please redirect my question. Thank you.

Updated version of this post My HomePod mini is now on version 16.4, so the the temperature and humidity sensors are enabled. The data properly shows up in the Home app on my various devices. In my HomeKit iPad app running on Mac Catalyst, however, the data does not show up. I would expect the HomePod mini to show up in HMHome.accessories with a service of type HMServiceTypeTempatureSensor. I see all of my other HomeKit accessories, just not the HomePod mini. I have tried with the latest Xcode (14.3) and highest available iOS Target and Minimum Deployment (16.4), macOS version 13.3. I have not, as of this writing, upgraded my HomeKit architecture, however. Note that I haven't tried the app on an actual iPad (and the iOS simulator doesn't expose my HomeKit environment.)

I am creating a barcode reader using the AVfoundation framework for iOS and IPadOS. The read result goes into payloadstringvalue, but I want to check the control characters contained in the symbol, so I am using the raw data of the description, which is a property of NSObjectProtocol inherited by VNBarcodeObservation. However, I noticed that if the length set in the raw data exceeds 26, some of the raw data in the description is omitted. So my question is, is it possible to set it so that all the raw data in the description is written out without omitting any raw data? If so, could you please tell me how to set this up? Also, if you know of any other way to extract the raw barcode data, I would appreciate it if you could let me know. Thank you.

I have a 4-input, 4-output hardware device and an 8-input, 8-output virtual device, which I combine into an aggregate device. I am using the SimplyCoreAudio library to get the channel count. The code is as follows: aggregationDevice!.channels(scope: .input) =>> 12 aggregationDevice!.channels(scope: .output) =>> 12 When the program's MicrophoneMode is set to standard, the channel count is correct. However, when I set the MicrophoneMode to voiceIsolation, the channel count is incorrect: aggregationDevice!.channels(scope: .input) =>> 4 aggregationDevice!.channels(scope: .output) =>> 12 Below is the code for creating the aggregate device： func createAggregateDevice(mainDevice: AudioDevice, secondDevice: AudioDevice?, named name: String, uid: String) -> AudioDevice? { guard let mainDeviceUID = mainDevice.uid else { return nil } var deviceList: [[String: Any]] = [ [ kAudioSubDeviceUIDKey: mainDeviceUID, kAudioSubDeviceDriftCompensationKey:1 ] ] // make sure same device isn't added twice if let secondDeviceUID = secondDevice?.uid, secondDeviceUID != mainDeviceUID { deviceList.append([ kAudioSubDeviceUIDKey: secondDeviceUID, kAudioSubDeviceDriftCompensationKey:1, kAudioSubDeviceInputChannelsKey:8 ]) } let desc: [String: Any] = [ kAudioAggregateDeviceNameKey: name, kAudioAggregateDeviceUIDKey: uid, kAudioAggregateDeviceSubDeviceListKey: deviceList, kAudioAggregateDeviceMainSubDeviceKey: mainDeviceUID, kAudioAggregateDeviceIsPrivateKey:false, ] var deviceID: AudioDeviceID = 0 let error = AudioHardwareCreateAggregateDevice(desc as CFDictionary, &deviceID) guard error == noErr else { return nil } return AudioDevice.lookup(by: deviceID) } I hope someone can tell me the reason Thank you！

Is there any way to use AccessorySetupKit in the background to discover BLE devices?

After updating to ios18.4, 3d scanning function, including AR function in apple clips, cannot be used. Does anyone else have the same problem?

Ever since the last update i have issues with my camera app. Sometimes when I open the app the forward facing cameras don’t work and it’s just a Black screen. I also get a warning that I may not have genuine iPhone parts installed. I have to reboot the phone every time just to have it app function again. It’s annoying. Please fix this. I never had any issues with the camera or its app up until after the update.

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？

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.

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!

I have a question about Apple certification. We are planning card reader via HID(human interface device) for iPad that support USB-C. iPad will receive data as HID protocol. In this case do I have to get certificate(for example MFi) like Apple USB accessory?

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, 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.

After hardware and mobile phone hid mode pairing, the first connection is successful, after a while disconnect and reconnect,APP monitoring Bluetooth error NSLocalizedDescription = "Peer removed pairing information"; Failed to connect Hardware engineers detect the pairing information and find that the local pairing information of the iPhone has changed, which is a non-mandatory phenomenon

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?

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.
