How to handle CoreNFC session timeout when APDU exchange exceeds 20 seconds?
I’m developing an iOS application using CoreNFC and working with ISO7816 tags. My use case involves exchanging APDU commands with a hardware device, but some operations can take more than 20 seconds. From my testing, I see that: The NFC reader session itself lasts about 60 seconds. But once a tag is connected, the connection seems to drop after ~20 seconds, and I receive a “connection lost” / session invalidated error. My questions are: Is this ~20-second connection window a hard limit enforced by iOS? Is there any way to extend this timeout for long-running APDU operations? If not, what’s the recommended design pattern for handling these scenarios? For example, should I split the process into smaller APDU commands and prompt the user to re-tap when the session times out? Any guidance or best practices for handling long NFC exchanges on iOS would be greatly appreciated.

CardSession.Error.maxSessionDurationReached not thrown on iOS 26
Hello, I have an app that emulates an NFC card using NFC HCE. Since yesterday I saw an increasing number of crashes on iOS 26 only, which wasn't there before. From what I can see, it seems the app crashes when the NFC presentment intent is shown and 60 seconds passed and user does nothing. The app just crashes after 60 seconds. On previous iOS versions, I know that CardSession.Error.maxSessionDurationReached was thrown after 60 seconds. Is something changed in iOS 26?

compile code required signing from unexisting user
Hi, This is my first time developing for iPhone, and I believe I have encountered an unusual edge case related to user management. Background: I work at a very small company currently in the proof-of-concept stage of building an iOS app. We created an Apple account under the company name: Green Vibe, using our corporate email. Initially, I developed the app under the free account on my local iPhone, and everything worked smoothly. When NFC functionality became necessary, we upgraded to a paid Apple Developer account. At that point, I enrolled as a developer under my personal name (Or Itach) while logged in with the Green Vibe Apple account. I want to emphasize that only one Apple account was created — the Green Vibe account. The Issue: When attempting to add NFC, I was able to create the required certificate under the name Or Itach. However, when compiling the project, Xcode prompts me to enter the login password for the user Or Itach. This is problematic because there is no Apple ID associa

NFC reader is not working in iOS 26

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.

Reply to Is there a way to disable NFC on iPhones?
If it is important for your app that NFC is supported, we would advise to keep on checking and gracefully handle the case where NFC may not be available to make sure your app works properly with all devices and iOS combinations past, present, and future.

Regression: CoreNFC crash happening through sole presence of a method
I sent this feedback some time ago and still haven't received an answer. Can someone poke someone internally please? Thank you! FB18815675 I have no idea what exactly is going on but after 5 days I found the culprit and I have a reproducible sample project. In the project is a package that does some basic NFC NDEF encoding. I put a commented out method in there and when you comment that in then the app starts crashing at runtime when scanning an NFC tag. Please check out the project and see yourself. Thanks https://github.com/NickAtGit/iOS26-CoreNFC-Crash

NFC innovation
Existing smartphones store multiple NFC card information. When the NFC antenna of the phone is close to the card reader, it is usually necessary to open the APP to select NFC card information or default to one card information to be transmitted to the card reader. It is not possible to quickly select or switch cards among multiple cards. For example, after using the NFC function to swipe the subway card, the phone needs to open the car access control and community access control again. It is necessary to open the mobile NFC card information management APP to select the community access control card and then swipe the mobile NFC access control, which causes inconvenience. （现有的智能手机存储多个 NFC 卡信息。当手机的NFC天线靠近读卡器时，通常需要打开APP选择NFC卡信息或默认一个卡信息传输到读卡器。无法在多张卡之间快速选择或切换卡。例如，使用NFC功能刷完地铁卡后，手机需要重新打开车内门禁和小区门禁。需要打开手机NFC卡信息管理APP选择社区门禁卡，然后刷手机NFC门禁，造成不便。） Divide the smartphone screen into multiple areas, and users can freely d

Reply to NFC Missing required entitlement
This error can be caused due to a couple reasons, based on the NFC tag being used. Based on your entries: For com.apple.developer.nfc.readersession.iso7816.select-identifiers, missing the Application ID used in a Select command will cause this error. For com.apple.developer.nfc.readersession.felica.systemcodes, the System code must be one of the provided values. If an invalid system code is used, this error will be returned. You also seem to have defined NDEF, so if this is an NDEF tag, this error will be returned if you start an NDEF session but the entitlement is missing. I can only go with what you have shown here, and if these settings are correct, then there is a mismatch of AIDs or system codes. If you confirm that everything is correct and matches, it is also possible that you have an issue with your build so the entitlements and the Info.plist entries and not being built into the app.

Go to Settings” button in Core NFC system alert does not navigate on iOS 26 beta
Description: While testing Core NFC functionality on iOS 26 beta, when the NFC switch is turned off, the system automatically displays an alert. The alert contains two buttons: “Cancel” and “Settings”. Expected Behavior: When the user taps the “Settings” button, the system should navigate to the system settings page where the NFC switch can be turned on. Actual Behavior: The alert appears as expected Tapping the “Settings” button does not navigate to the system settings page No callback is triggered in the app’s NFC session Steps to Reproduce: Turn off the NFC switch on an iOS 26 beta device Trigger Core NFC functionality (e.g., NFCNDEFReaderSession or NFCTagReaderSession) The system alert appears indicating NFC is turned off Tap the “Settings” button Impact: Users cannot directly navigate to enable NFC from the system alert, making NFC features in the app unusable and negatively affecting user experience.

App Review for Application using HCE capabilities
Hello, We're working on an application using (https://developer.apple.com/support/hce-transactions-in-apps/) We have some questions App review with this capabilities: There are 4 mains points written on the page, does all are required? Test login details Does it need to be production or testing environnement? Can it be a URL/Deeplink or is it a mandatory login/password credential kind? At least one test payment credential that can be provisioned and used in your HCE app for the purposes of making an NFC transaction That's the difficult part, can we have more details about this condition? Does it need to be a production card or a testing card? Screenshots or video of your app being used at a terminal for an NFC transaction OK, make sense Video of your app demonstrating an implementation of the Presentment Intent Assertion API OK, make sense Thanks François
