After the 'IdentificationAccepted' message, I sent 'RequestAppLaunch' with 'AppBundleID' and 'AppLaunchMethod'. However, the app isn't launched by the external accessory. I checked it with ATS and saw the error message: 'Error: accessory sent a message that the Apple device did not acknowledge during identification. Section: Section 28.2.2 Sent/Received iAP2 Control Session Messages. Source: Accessory Interface Specification R42.' Do you have any idea how to fix it? Thank you in advance.

Issue: Amtrak's state partner in New Jersey, SEPTA, has requested the incorporation of NFC suppression when an Amtrak mobile ticket is opened on their app. This feature ensures that NFC remains inactive and does not inadvertently bring up Apple Pay, Google Pay, etc., when customers are trying to scan their Amtrak tickets on SEPTA validators. Request: Amtrak is requesting to use the entitlement com.apple.developer.passkit.pass-presentation-suppression in our Amtrak app to suppress the display of Apple Pay passes when the app is in use. This is to prevent interference with the NFC reader during ticket validation, as illustrated in the attached screenshot from SEPTA's app, which shows a similar implementation with the message: "Payment cards and passes will not work automatically while NJ TRANSIT is in use." Entitlement Information: Entitlement Key: com.apple.developer.passkit.pass-presentation-suppression Boolean Value: YES Justification: The entitlement will enable the requestAutomaticPassPresentationSuppressionWithResponseHandler: method to keep the Amtrak app in the foreground when operating near NFC or other RF readers. This feature is crucial for ensuring seamless ticket scanning and validation for our passengers without the interference of Apple Pay or other digital wallets. Reference Documentation: For more information on this entitlement, please refer to the Apple Developer documentation: Apple Pay and PassKit Entitlements. Implementation: In our entitlement configuration file, we will add the following key: com.apple.developer.passkit.pass-presentation-suppression Supporting Evidence: The SEPTA app demonstrating the implementation of this feature can be found in the App Store. Amtrak seeks to implement a similar suppression mechanism, displaying the message: "Payment cards and passes will not work automatically while Amtrak app is in use." We seek Apple's approval for this implementation to prevent any potential rejection of our app store submission for incorporating this critical feature for our state partner's requirements. Thank you for your consideration.

Only issue I’ve noticed so far with my 15 pro 256 is that trying to newly pair AirPod pro’s gen 2, settings acknowledges AirPods however, UI does not appear when setting AirPods in pair mode.

Many USB storage devices are NVMe devices accessed through a USB-NVMe bridge chip, such as those by JMicron and Asmedia. These chipsets do not forward SMART data requests to the devices, but do have the capability to forward raw NVMe commands to the devices using vendor specific requests. How can we provide access to SMART data for NVMe devices accessed through a bridge chip like this? Many people used the OSX SAT SMART kext driver to provide access to SMART data for devices using USB-SATA chips, but it is a kext and doesn't support NVMe. See https://binaryfruit.com/drivedx/usb-drive-support#install-instructions Would we need to implement a kext like that to make this work? Is there a DriverKit way to do this?

How to set Tx power level for iphone

Since moving up to IOS18 lat week I am getting an indication that there was a significant drop in IMU data being sent. Using the search capability, I can find very little information in the Developer Documentation that will tell me what the cause is and how to remedy it. Is there some documentation repository like Tech Notes that will tell me what I need to know to get going again? What additional sources of documentation are available for developers? The Search engine used for Developer documentation just does not cut it because it delivered a lot of useless entries that have no obvious relevance to my search terms. "2024-06-20 19:27:00.669334-0500 RoomPlanExampleApp[902:299709] [Technique] ARWorldTrackingTechnique &lt;0x104bf6d80&gt;: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop].

When using external NVMe devices on iOS / iPadOS I cannot tell how to access the disk SMART data. On macOS I can use NVMeSMARTLibExternal.h to access this information but the same system does not seem to work on iPadOS (even with Thunderbolt NVMe devices). When using M series iPads with professional Thunderbolt storage this woudlbe very useful.

Hello, We are currently developing a device with a USB-C drive, and we want to connect it to iOS devices to import the stored files into our app. I have a few questions regarding this: MFi Certification Requirement We believe that MFi certification is not necessary for USB-C connections. Is this understanding correct? Implementation Method We prefer not to use standard components like UIDocumentPickerViewController. Are there any methods to access the file system directly, or any other suitable approaches you can recommend? If anyone has experience with this, your advice would be greatly appreciated. Thank you in advance.

Hello…! I have bought an iPhone from flipkart on 07/10/2023 Which is around 10 months old and my battery health is decreased that is 89% I am facing issue of battery draining and phone heating while charging the phone. Please solve my query what i have to do

My battery health has dropped from 98% to 93% in the last 5 months. I bought my iphone 15 pro max last september, it hovered at 98% till january and then has been dropping at a rate that makes me feel uncomfortable and has reached 93% now. Is this normal or am I being paranoid? is there anything i can do to slow this down?

We want to use AccessorySetupKit to pair our BLE accessories. However, currently all our products announce the same BLE service UUID. The manufacturer data is different for every product. I try to pair our products with ASK and create the ASDiscoveryDescriptor with the expected manufacturer data: let descriptorA = ASDiscoveryDescriptor() descriptorA.bluetoothServiceUUID = CBUUID("CE1EB45C-1BD2-45BE-8163-ACC88BE94CB2") // same descriptorA.bluetoothManufacturerDataBlob = Data([0xd2, 0x0a, 0x00, /* A */ 0x2a, 0x00, 0x00, 0x00]) // different descriptorA.bluetoothManufacturerDataMask = Data([0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff]) let descriptorB = ASDiscoveryDescriptor() descriptorB.bluetoothServiceUUID = CBUUID("CE1EB45C-1BD2-45BE-8163-ACC88BE94CB2") // same descriptorB.bluetoothManufacturerDataBlob = Data([0xd2, 0x0a, 0x00, /* B */ 0x2b, 0x00, 0x00, 0x00]) // different descriptorB.bluetoothManufacturerDataMask = Data([0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff]) However, it seems random which device is found, as if the service UUID is the primary key to handle things in ASK. My questions are: Is it possible to use only manufacturer data to distinguish between different products with the same service UUID? How do I use bluetoothManufacturerDataMask properly? I assume that internally some filtering like this is done: DataBlob & DataMask == ReceivedManufacturerData & DataMask. Because of that I have set all bits of the mask to 1. Should this e done differently?

I have created a Flutter application to scan Mifare DESFire cards on Android and iOS. I have tried using both flutter_nfc_kit and nfc_manager which both use CoreNFC. On both platforms, I can get the basic information on the card. However, only on Android, I can read data from the card by using Mifare commands. On iOS I am getting a 0B response. I have the following configuration inside my Runner.entitlements: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> </array> </dict> </plist> I have added the following keys inside my Info.plist file: <dict> <key>NFCReaderUsageDescription</key> <string>Access NFC</string> <key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key> <array> <string>D2760000850100</string> </array> ... </dict> However, I have noticed that I will get a different response if I add the D2760000850100 key in the Info.plist file. When I have this key added I get an error when executing a Mifare command: PlatformException(500, Communication error, Tag response error, null) So for that reason, I decided to remove the key altogether. Now everytime, I execute a Mifare command I end up with the response of 0B. Which does not tell me anything because it is not an official response. The Mifare command I am using is the select application command: 5A123456 where 123456 is the application ID. As mentioned before this works perfectly on Android. The only response I can get from the Mifare DESFire card is with an ISO7816 command: 00A4040006D2760000850100. Which is the select application command according to the ISO7816 standard. However, after executing this command I need to authenticate, which requires a complex algorithm. Is it necessary on iOS to first execute ISO7816 commands, before you can execute Mifare commands?

Simple question: can I shoot log using the new MVHEVC format for spatial video for viewing on the Vision Pro?

I set up my app very similar to the sample app, putting the Service UUID in the plist and descriptor, I am able to see the picker but when my device is advertising, it doesn't seem to be responding to it. I see it stuck on "Discovering" and then it times out saying "Make sure the accessory is nearby and ready to connect". I also noticed that when I remove the ASK code but leave in the ASK fields in the info plist, my CBManagerAuthroization state is always "not determined". Can anyone help me troubleshoot these 2 issues? Perhaps they are related?

Hello, I am experiencing an issue with background serial communication on my iPad Pro when using a Type-C connection to an external device. Specifically, when the app is inactive, in low power mode, or when the screen is locked (i.e., not active), the communication with the external device is interrupted. However, this problem does not occur when using a Lightning cable on my iPad Mini. In that setup, the background serial communication works seamlessly under the same conditions. Has anyone encountered a similar issue or have any insights into why the behavior differs between Type-C and Lightning connections? Any suggestions or workarounds would be greatly appreciated. Thank you!

Since 17.4 Dev Beta 2, I have been having Bluetooth issues. I had hoped it would have cleared up but even in 17.4.1 it continues. Airpod and Echo Auto are the only 2 audio devices I have. The audio will become chopping, rubber band or sound robotic and sometime completely disconnect. While driving it will occur on both audio devices. Sometimes I'm stopped at red light and the issue occurs. The phone is less than 3 feet from the device at all times. I have read forums and removed and readded the devices but that did not help. I really do not want to have to reset my phone since my 2FA apps do not recover in a restore. Anyone have any suggestions?

I was trying to use my MacBook Air M1's left USB port to connect to my USB hub setup (including a DisplayLink hub and regular powered USB hub), but they would only work on the right USB port (unless I have it plugged in from a cold boot). I also found out that I can plug my charger into the port and it would work correctly, and connect my iPhone to the port and have it charge out to the phone correctly (but cannot transfer data between devices). These issues seemed to have started happening when I did a clean restore of macOS Sequoia (so there is a chance that I might try reinstalling Sonoma instead to see if that fixes the issue). Has anyone else encountered this sort of issue?
