Battery issue iPhone 13 ProMax iOS 18.6 Beta
Since updating to iOS 18.6 beta on my iPhone 13 ProMax, my battery usage has well over doubled. Also, my phone has become noticeably sluggish and unresponsive. For instance, after being charged to 100% my phone has dropped to 26% with only 1 hr 2m screen on time and 49m of screen off time. My phone gets noticeably warm to the touch, even through the case. Any ideas on the cause or any remedy?

How and when to use .confirmAuthorization option with AccessorySetupKit
I am developing an app that communicates with external BLE device over GATT. The device has a secure-read characteristic exposing some of it's data and requires pairing/bonding in order to communicate with it. I was able to pair and connect with the device using AccessorySetupKit and .bluetoothPairingLE option: let descriptor = ASDiscoveryDescriptor() descriptor.bluetoothServiceUUID = CBUUID(string: serviceUUID) descriptor.supportedOptions = [.bluetoothPairingLE] let picketItem = ASPickerDisplayItem(name: name, productImage: image, descriptor: descriptor) In this case when setting up accessory, I was prompted to compare passkeys and after confirming I can read the characteristic etc. Then I tried adding .confirmAuthorization to picker item and problems started: let descriptor = ASDiscoveryDescriptor() descriptor.bluetoothServiceUUID = CBUUID(string: serviceUUID) descriptor.supportedOptions = [.bluetoothPairingLE] let picketItem = ASPickerDisplayItem(name: name, productImage: image, desc pickerItem.setupOptions = [.confirmAuthorization] When setting up, I can see a passkey to be confirmed, but when confirmed the setup ui get's suck in loading state. Under the hood in logs, I can see that my app has connected to peripheral and was able to read the characteristic. I am unsure why the ui is stuck in loading state in this case. What is the difference when using .confirmAuthorization option and what should be the proper flow of events to setup accessory and then access protoected characteristic?

HomeKit ADK Remote.OpenSSL fails with No setup info found in key-value store during pairing (HAPPlatformAccessorySetup.c:93)
Hello Apple Developers, I'm currently working on building a custom HomeKit Accessory using the HomeKit ADK v6.3 and running the Remote.OpenSSL sample on a Raspberry Pi 4 (64-bit Ubuntu / Linux Kernel 6.1.21-v8+). I'm trying to pair the accessory via the MFi HomeKit ADK pairing process. I've successfully compiled the ADK using: The application (Remote.OpenSSL) launches correctly, and the accessory server starts as expected, broadcasting via mDNS. However, when I attempt to initiate pairing via iOS (or simulate pairing), the following error occurs: Fault fatal error - HAPPlatformAccessorySetupLoadSetupInfo @ PAL/Linux/HAPPlatformAccessorySetup.c:93 This causes the application to crash.

The volume of the human voice recorded by the microphone is too low when media is playing
We found that on some iPad devices (such as iPad8,9/iPad OS/18.5), when the media is playing, the recorded human voice is very small and is basically suppressed by the sound of the playing media. When the media is not playing, the human voice can be recorded. Likely when use screen recording with microphone, the ambient sound is also basically suppressed by the media sound.

The local network connection suddenly fails
Our app is connected to a hardware wifi without network. Under normal circumstances, we can communicate with the device. At some point, the communication suddenly stops, and the ping prompts "No route to host". The only way to reconnect is to restart the device. It feels like the system has marked ARP. Is there any way to reconnect the device without restarting the iphone?

Rapid Battery Health Degradation on MacBook Pro (Less Than 1 Year Old, 302 Cycles)
I’m currently experiencing a concerning battery issue on my MacBook Pro and wanted to share it here in case others are facing something similar or if it’s possibly tied to a software-level behavior. Device & Software Info: • MacBook Pro 14” (2023) • macOS 26.0(25A5316i) • Battery Cycle Count: 307 • Battery Health: 91% (as of today) • Condition: Normal Issue: • Battery health has dropped from 96% to 91% in less than a week. • For the last week each day, the maximum capacity seems to decline by 1%, even when usage is light and the Mac is plugged in most of the time with Battery Health Management enabled. • When the battery drops below 10%, it drains extremely fast — the percentage decreases nearly second by second, which doesn’t feel normal.

Inquiry Regarding Remote Control and Screen Sharing Capabilities Under MFi Program
Dear Apple Developer / MFi Program Support, I am exploring technical possibilities for screen sharing and remote interaction between iOS devices and external hardware (e.g., embedded systems, in-vehicle systems) for a prototype we are currently developing. I have reviewed the public iOS developer documentation, but I would appreciate your guidance and clarification on the following advanced use cases, particularly in the context of MFi or enterprise-level integrations: Full-Screen Sharing of iOS Device Is it possible to mirror or stream the entire iOS screen, even when the app is running in the background or not in the foreground? Does ReplayKit or any other framework under the MFi or enterprise entitlements allow full-device screen capture outside the app context? Remote Touch Injection and Control Is there any officially supported mechanism, under MFi or otherwise, that allows external systems to remotely control an iOS device’s touch interface (e.g., simulate gestures, taps, swipes)? Are any of the following permitted under special entitlements: Access to IOHIDEventSystem or similar private APIs for input injection? Communication over USB or network to relay control commands that simulate direct user interaction? Hardware-Level Integration and Entitlements Does the MFi Program allow: Use of private frameworks or entitlements to build low-level integrations for iOS device control or mirroring? Communication over USB/Lightning/USB-C to enable bi-directional interaction (streaming out, commands in)? What are the specific APIs or entitlements available under MFi that enable these use cases? Can you provide references to documentation, SDKs, or prerequisites for companies seeking such capabilities? Eligibility and Certification Process What are the criteria to be approved for the MFi program with access to such advanced capabilities? Can PoC or early-stage research prototypes be eligible, or is MFi access restricted to commercial production intent? How long does it typically take to gain access to these entitlements (assuming NDA and certification requirements are met)? Alternative Pathways If MFi access is not feasible in the short term, is there any Apple-supported alternative path (e.g., test device provisioning, enterprise signing, custom profiles) that permits more advanced capabilities for prototyping purposes? We are not looking to publish this as a general App Store app at this stage, but rather to demonstrate feasibility as part of an innovation prototype that may lead to further OEM-level engagement in the future. Thank you for your support and guidance. Best regards,

iPadOS26 beta4 Tap Judgement
On the iPad Pro 12.9-inch (3rd generation) cellular model, when you touch the screen with four fingers and then move your fingers, the touch is no longer detected. The same operation with one to three fingers works normally. This phenomenon does not occur when accessibility is turned on. Is this a beta-specific issue that will be fixed in the official release?

Apple Pencil Pro Haptic Initiation
Hello, The Apple Pencil Pro brought with it the UICanvasFeedbackGenerator API, which lets us trigger haptic feedback on discrete events initiated by the pencil. That works fine. My question then: is it possible / are we "allowed" to trigger haptic feedback on events that weren't initiated by the pencil? For example, say the user is using a left hand finger to drag a slider, while holding the pencil in their right hand-- would it be possible to make the pencil vibrate to indicate the dragged slider knob reached a certain point? Or is the rule that vibration is only possible/allowed when the pencil itself generated a touch? Thanks!

Is there a way to disable NFC on iPhones?
I have some logic which requires NFC support on the device. This is what I'm using to make sure that it's available: isNFCMissing = !NFCNDEFReaderSession.readingAvailable && !NFCTagReaderSession.readingAvailable && !NFCVASReaderSession.readingAvailable Is it possible for isNFCMissing to be true even if the device has an NFC chip. The minimum iOS version for the application is 16 which is only supported on devices with an NFC chip to begin with.

Mac OS X App for collecting linear displacement of a sample
I have a small furnace that heats a sample of my product, a cylinder measuring 20mm x 100mm. As it is heated, there is thermal expansion, and I at this moment read (using my eyes) a micrometer dial gauge and type into my app the value read in hundredths of a millimeter. My source code uses quartz to draw a PDF graph that represents this thermal expansion. I would like to enhance my set up by getting my app to collect the linear displacement from my dilatometer furnace. One possibility I have been trying to implement is to have my app collect DC millivolts from an instrument, like a voltmeter reading the output of an LVDT (Linear Variable Differential Transformer), but the model I have requires MODBUS-RTU protocol, which is not well implemented by Mac OS X developers. It requires an USB-Serial converter, which complicates things and makes it more unreliable. At this moment, I have to sit next to my furnace and type into my app the temperature and linear displacement for 3 hours. I would like to read some comments and suggestions from you or an Apple Engineer and how this could be achieved. Here is a video of my dilatometer furnace: https://www.correiofacil.com/video/IMG_8888.MOV Here is a PDF I generated using my APP: https://www.correiofacil.com/PDF/117.pdf Here is a video showing how I type data manually into my app: https://www.correiofacil.com/video/recording2.mov Here is a video that shows my app drawing a graph: https://www.correiofacil.com/video/recording1.mov These 2 images show my attempts to use the app ModBusRtuMaster to collect data from the voltmeter which at this moment fails: https://www.correiofacil.com/PDF/8f9be971dee32a58c36b307dbab3dc2d.png https://www.correiofacil.com/PDF/4ac20c2ea762fd42ed340a7a2b567900.png You will notice that although the instrument is displaying 0.000 volts, the data collected changes at each message I send to the instrument, proving me that Modbus RTU set up is not working. Here is a link to the manual of the DC voltmeter I am using: https://www.correiofacil.com/PDF/manual1.pdf Here is an image of the LVDT I am trying to use: https://www.correiofacil.com/PDF/e0349986512f9273b26b209baa3ba5c7.png Here is the manual for the LVDT: https://www.correiofacil.com/PDF/GGD19.pdf I suspect that there could be a completely different approach to collecting the data and inputting into my app, maybe Bluetooth? Maybe using a Mitutoyo gauge such as? This: https://www.mitutoyo.com/Images/CatalogUS-1003/resources/_pdfs_/US-1003_Catalog_251.pdf And a cable with SPC support like this: https://www.gw-style.com/product-p-942977.html I am very grateful for your comments

iphone17 Core Bluetooth Background Execution Modes
Hello. Is there a solution to the issue where Core Bluetooth does not run in the background on the iPhone17? https://developer.apple.com/library/archive/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html The bluetooth-central Background Execution Mode When an app that implements the central role includes the UIBackgroundModes key with the bluetooth-central value in its Info.plist file, the Core Bluetooth framework allows your app to run in the background to perform certain Bluetooth-related tasks. While your app is in the background you can still discover and connect to peripherals, and explore and interact with peripheral data. In addition, the system wakes up your app when any of the CBCentralManagerDelegate or CBPeripheralDelegate delegate methods are invoked, allowing your app to handle important central role events, such as when a connection is established or torn down, when a peripheral sends updated characteristic values, and when a central manager’s state changes. Although you can perform many Bluetooth-related tasks while your app is in the background, keep in mind that scanning for peripherals while your app is in the background operates differently than when your app is in the foreground. In particular, when your app is scanning for device while in the background: The CBCentralManagerScanOptionAllowDuplicatesKey scan option key is ignored, and multiple discoveries of an advertising peripheral are coalesced into a single discovery event. If all apps that are scanning for peripherals are in the background, the interval at which your central device scans for advertising packets increases. As a result, it may take longer to discover an advertising peripheral. These changes help minimize radio usage and improve the battery life on your iOS device.

Alternative to generate programmatically a local hotspot like in Android?
Hello, we are developing hardware that needs to connect to an iPhone via Wi-Fi to send requests to a server. On Android, we have managed to create a programmatic local hotspot within the app to facilitate connection and improve the user experience. On iOS, however, Personal Hotspot must be manually enabled from the system settings, and the user must manually enter the SSID and password, which significantly degrades the UX. My questions are: Is there a workaround, unofficial method, or private API to generate a local hotspot from an app on iOS, similar to what can be done on Android? Is there an alternative within the MFi program or through specific frameworks to facilitate a quick and automatic connection between the hardware and the iPhone without relying on the manual Personal Hotspot? Are there any best practices for improving the local Wi-Fi connection experience between an accessory and an iPhone in the absence of hotspot controls? I would appreciate any guidance, experience, or resources that would help me better understand the feasible options in iOS for scenarios where fast and direct communication between hardware and mobile devices via Wi-Fi is required.
