During EEPROM reading or writing on some appliance devices, the app encounters an error after 6 steps. This issue occurs only on iPhone 14 Pro Max, 15 Pro Max, and 16 Pro models, while all other iPhone models function correctly. Any one with this problem?

Background: We are developing a cross-platform mobile application that communicates with a custom NFC-enabled hardware device. The hardware expects ISO7816-style APDU commands for data exchange and functions correctly with Android using the IsoDep protocol. Observed Issue on iOS: On iOS, the tag is only detectable via NFCNdefReaderSession, which provides access to INFCNdefTag. Attempting to use NFCTagReaderSession with NFCPollingOption.Iso14443 (which is required for APDU communication) results in no tag detection. As a result, the tag is inaccessible for APDU-based communication on iOS. Since NFCNdefReaderSession does not support APDU, we are unable to establish the required command channel. Constraints: The hardware firmware cannot be changed to support NDEF-based command interpretation. The device expects raw ISO-DEP APDU commands (i.e., Class-Instruction-Param1-Param2-Data-Le). Impact: The lack of ISO7816 tag detection on iOS prevents the app from sending APDU commands, resulting in a platform-sp

I stumbled across the Apple NFC & SE Platform while searching for the cause to a persistent missing entitlement error. I am curious if not having this entitlement could be the root cause to my issues? Specifically, I am trying to perform an HMAC-SHA1 challenge-response via NFC on a YubiKey. Part of this entails low level APDU Send commands via NFC. The missing entitlement occurs right after the APDU Send. Per my separate post, I believe I have exhausted all other possible causes to no avail. For reference and details, this is the other post: [https://developer.apple.com/forums/thread/791995)

The root issues is a missing entitlement error. I've jumped through countless hoops of checking/rechecking .entitlement file/plist file, creating new credentials, creating new projects, creating new provisioning profiles with no luck, manual signing, automatic signing. Any suggestions appreciated. Looking at the Provisioning Profile Info shows NFC Tag capabilities is included and NFC Entitlements are included. I'm at a loss... I am including the following: Pertinent output from console Current Info.Plist Current .entitlement file Here are the pertinent sectsis the Console Log for reference: ...

Hi everyone, I’m working on an iOS project where an iPhone needs to connect to external scanners (dedicated hardware devices) over Wi-Fi. The goal is to: Discover available Wi-Fi networks from the scanner devices (broadcasting their own networks). Allow the user to seamlessly connect to the chosen scanner network. Network Discovery: Is there a way to programmatically list available Wi-Fi networks (SSIDs) on iOS without private APIs? If not, are there workarounds (e.g., Bonjour/mDNS)? Seamless Connection: As I see, we can use NEHotspotConfigurationManager to connect to and disconnect from specified networks and there will always be a system alert asking about do we really want to join this network Hardware/Firmware/Software Alternatives: If iOS restrictions prevent this, what alternatives exist? For example: Hardware: Scanners supporting Bluetooth LE for initial pairing, then Wi-Fi provisioning. Firmware: Scanners acting as clients on the same network as the iPhone (e.g., via user’s home/office Wi-Fi). Softwar

I am trying to launch Nfc session but its failing with the below error ** CoreNFC CRASHING_DUE_TO_PRIVACY_VIOLATION NSLocalizedFailureReason = This app cannot be installed because its integrity could not be verified. Failed to verify code signature ... (A valid provisioning profile for this executable was not found.)** But We have declared NFC in capabilities both in code base and provisioning profile.

Hello Apple Developer Community and Apple Team, I want to raise awareness and gather support for an important feature request regarding NFC support on iPhone devices in Argentina. Millions of Argentinians use the official public transit card, SUBE, daily to pay for buses, subways, and trains. On Android devices, the SUBE app allows users to: • Check balance via NFC • Reload credit instantly • Confirm top-ups by holding the card near the phone • Use a digital version of the card (in some cases) However, iPhone users cannot use these NFC features because iOS currently does not allow third-party apps like SUBE to access the NFC chip fully. This limitation negatively impacts iPhone users, many of whom rely heavily on SUBE. I have submitted detailed feedback to Apple requesting the enablement of controlled NFC access for third-party transit apps in Argentina, starting with SUBE. I encourage fellow developers, users, and community members to support this request. Enablin

我们在使用clip轻应用功能，在App Store Connect中配置了高级轻应用体验，并配置了相关的https链接（在构建版本页面此域名是已验证状态），但是我们在使用此链接进行NFC触碰时，不会拉起来clip轻应用，只会显示“XXXX NFC标签”，使用Apple的官方链接：https://appclip.apple.com/id?p=xxxx，是可以拉起来轻应用的，请问各位大佬，我们的问题出现在哪？该如何解决？

This post contains sensitive language. Please revise it in order to continue.Hello, We are working on digital key style application using custom communication with HCE (Host Card Emulation). We have a working solution but there is one issue - if our application is not selected as default NFC application our users may see Wallet popup when there's no active presentment intent in our application. I didn't find in documentation any information how to stop Wallet from activating. I found there's requestAutomaticPassPresentationSuppression method in PassKit, it requires special permission, however I am not sure if it can be used in this situation, as there's no information how it will impact HCE communication in our application. I'll be greatful for any advice. Regards, Valdemar

Some background: We are developing an app that needs to scan NFC tags We are following this documentation for our app We (assume) we've gotten all the correct entitlements for our app Our app correctly shows the NFC scanning prompt We are using up-to-date iPhones to test We tested scanning using a different NFC app on the app store and were able to successfully scan the tag We're using NFC NDEF tags to test The problem: Nothing is being detected in the scan Nothing in the example application when we downloaded it down and loaded it onto a test device (reminder that the app from the app store was able to read our tag) When connected to the debugger, our delegate function is not firing (tested with breakpoints and print statements). The following is the signature of our delegate function: func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage]) Is there something that we're missing to get the NFC scanning to work? Perhaps some ki
