I have the our device connected , with Assistive Touch enabled and the application running in the foreground. At this point, I place the screen on standby and leave the device unattended for 10 minutes. After this period, I return, unlock the screen, and observe that our app is still running, and the connection with the device is re-initiated. However, something occurs at this stage that causes the application to briefly switch to the background and then immediately return to the foreground. This behavior leads to system instability. Ideally, once the application is running in the foreground, it should not transition to the background automatically. However, it seems to be doing so for a short duration—momentarily switching from the foreground to the background, then back to the foreground—which is causing the observed instability.

Hi l've updated to ios 18.1 beta and l'm experiencing my iPhone 14 Pro restart and having issues using Safari when on my home WiFi but I'm the only person in my household with this issue

I am experiencing an issue with NFC scanning on my iPhone 11 after updating to iOS 18. Previously, I was able to use NFC tags without any problems. However, since the update, the NFC functionality no longer works as expected. Installed OS: iOS 18.0 (22A3354) Here are the troubleshooting steps I have already tried: Opened the Shortcuts app. Tapped on Automation. Searched for NFC. Selected Run after confirmation. Tapped NFC Tag -> Scan. Unfortunately, nothing happens at this point; the NFC scan doesn't initiate. This issue has made it difficult for me to use NFC-dependent automations and functionalities that worked seamlessly before the update. Could you please provide guidance on how to resolve this problem? Thank you for your attention and support.

I know this will sound like a weird use case, but it is potentially relevant to a product I am working on. If I were to link two or more iPhones to the same iCloud account (I know this is uncommon and generally a bad idea, but it is possible so I have to consider it). Next I pair a BLE device to one of the phones using my app which has the background bluetooth permission with the app acting as the central so it can automatically restore a connection when the BLE device comes back into range. I then install the same app on the other iPhone(s) linked to this account and separate them physically so they are out of BLE range of each other. The BLE device is taken out of range of the first phone and into range of one of the others. First question is will the BLE device automatically connect to the other iPhone? If yes, will the app have any way of determining that it's running on a different iPhone with the same device connected? If yes, can the app prevent connection to the other phones in some way?

Hello fellow developers, I’m developing a smart standing desk under my brand Beflo, which integrates technology with traditional furniture. As part of this, we’re working to make our Tenon smart desk compatible with the Apple HomeKit ecosystem. While exploring HomeKit profiles, I noticed there isn’t a specific profile for standing desks. However, there are similar profiles, such as curtains, which also use motors for operation and could align with our product's functionality, like height adjustments. I have a few questions: What is the process for proposing or applying for a new product profile in HomeKit? Is it feasible to adapt an existing profile (like curtains) in the interim while awaiting approval for a new profile? Has anyone had experience navigating this process, and are there any best practices or resources you recommend? I’d love to hear insights from anyone who has experience with HomeKit development or working on similar product integrations. Thank you for your time and guidance!

My phone broke a little bit ago, with the screen either flashing green or it being green continuously. I asked somebody who would know and he said that the connection from the motherboard to the screen is messed up. It’s refurbished so that makes sense. Since then, the issue has gone away. it stopped a few days ago but I have insurance on it through a third party and I’m wondering if I should still make a claim.

For the "Required device capabilities" in my info.plist I have: iPhone Performance Gaming Tier iPad Minimum Performance M1 But a beta test just informed me they cannot install on iPhone 16 Pro Max due to "incompatible hardware" I need to limit to iPhone 15 or newer and M1 or newer. I read that iPhone Performance Gaming Tier also limits iPads to M1 here: https://developer.apple.com/forums/thread/737946 Perhaps I should only use "iPhone Performance Gaming Tier" and by using "iPad Minimum Performance M1" it is not allowing it to be installed on an iPhone? It would be very nice if I could see what devices are supported by the current settings.

Background Information In the macOS operating system environment, Program A uses libusb to access USB devices that comply with the USB Mass Storage protocol. To enable Program A to start automatically after macOS boots, its corresponding plist file has been placed in the /Library/LaunchDaemons directory. Problem and Phenomenon Description Program A works well on macOS versions prior to 15.3, and it can access USB devices normally. However, on macOS 15.3, the following abnormal situations have occurred: A. Program A launched by launchd cannot access the USB device. Checking the logs reveals that the IOCreatePlugInInterfaceForService call in the darwin_claim_interface function returns the error code e00002be. B. Program A launched from the terminal command line with sudo privileges can access the USB device normally, and the return value of the IOCreatePlugInInterfaceForService call is 0.

Since tvOS 18.4 beta (22L5218l) i have the issue that When I turn off an Apple TV, the Apple TV and the connected TV turn off, but after a few seconds the devices start again. This never happened before. But now it is happening with 3 different Apple TV generations on 2 LG and 1 Telefunken TVs. All 3 Apple TV devices have been updated to tvOS 18.4 beta (22L5218l) and since then show this error.

I downloaded "Dockkit ADK 1.0" and trying to compile, and some openssl include .h files are missing, for example in HAPBoringSSL.c, the below files can't found: #include <openssl/bn.h> #include <openssl/evp.h> #include <openssl/hkdf.h> #include <openssl/hmac.h> #include <openssl/rand.h> where can I get these .h files? I'm worrying about the version conformance if I fetch these files from internet.

I'm looking for technical documentation on Apple's IEEE 754 implementation on the M1 - M4 chips. Specifically, I'd like to know how NaN payloads are handled in arithmetic operations. Does anyone know where this information is available? Thank you!

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

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?

I updated my iPhone to 26 and I just went to to to see if my iPhone was up to date I went and see but a came across this

Hi everyone, while testing HKWorkoutSession with HKLiveWorkoutBuilder on iOS 26 Beta (cycling workout), I noticed the following behavior: – Starting a cycling HKWorkoutSession automatically connects to my Bluetooth heart rate monitor and records HR into HealthKit ✅ – However, my Bluetooth cycling power meter and cadence sensor (standard BLE Cycling Power & CSC services) are not connected automatically, and no data is recorded into HealthKit ❌ On Apple Watch, when starting a cycling workout, these sensors do connect automatically and their data is written to HealthKit — which is exactly what I would expect on iOS as well. Question: Is this by design, or is support for power and cadence sensors planned for iOS in the same way as on watchOS? Or do we, as developers, need to implement the BLE Cycling Power and CSC profiles ourselves (via CoreBluetooth) if we want these metrics? Environment: – iOS 26 Beta – HKWorkoutSession & HKLiveWorkoutBuilder (cycling) – Bluetooth HRM connects automatically – BLE power & cadence sensors do not This feature would make it much easier to develop cycling apps with full HealthKit integration, and also create a more consistent user experience compared to watchOS. Thanks for any insights!

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?

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,

Hello, The application I'm working on must report new hardware connections. To retrieve connected displays information and monitor new connections, I'm using the "Core Graphics" framework (see recommendation https://developer.apple.com/forums/thread/779945). The monitoring logic relies on a callback function which invokes when the local display configuration changes(kCGDisplayAddFlag/kCGDisplayRemoveFlag). #import <Cocoa/Cocoa.h> static void displayChanged(CGDirectDisplayID displayID, CGDisplayChangeSummaryFlags flags, void *userInfo) { uint32_t vendor = CGDisplayVendorNumber(displayID); if (flags & kCGDisplayAddFlag) { if (vendor == kDisplayVendorIDUnknown) { NSLog(@"I/O Kit cannot identify the monitor. kDisplayVendorIDUnknown. displayId = %u", displayID); return; } NSLog(@"%u connected. vendor(%u)", displayID, vendor); } if (flags & kCGDisplayRemoveFlag) { NSLog(@"%u disconnected", displayID); } } int main(int argc, const char * argv[]) { @autoreleasepool { CGDisplayRegisterReconfigurationCallback(displayChanged, NULL); NSApplicationLoad(); CFRunLoopRun(); } return 0; } The test environment is a Mac mini with an external display connected via HDMI. Everything works correctly until the system enters sleep mode. Upon wakeup, the app reports two displays: the first with vendor ID kDisplayVendorIDUnknown and the second with the expected vendor ID. Why does Core Graphics report two connections during wakeup? Is there any way to avoid this? Thank you in advance.
