Hi everyone, I'm working on a library application that uses ISO15693 NFC tags embedded in books to track checkout status. These tags are password-protected and require secure access in order to write the AFI (Application Family Identifier) field, which we use to mark books as checked out. According to the tag spec (ST SL2S2602), the flow for writing to a protected AFI requires: Sending Get Random Number (custom command 0xB2) Sending Present Password (custom command 0xB3) Writing AFI using Write AFI (0x27) We’re using Core NFC's customCommand(requestFlags:customCommandCode:customRequestParameters:) on NFCISO15693Tag. While basic tag operations like getSystemInfo() and readSingleBlock() work fine, any customCommand immediately fails with this error: Error Domain=NFCError Code=100 Tag connection lost This only happens on tags that return ICRef = 0x01 in the system info response. The exact same tags and command sequence work fine on Android (transceive) and in desktop NFC tools. It look

I am working with a Texas Instruments RF430 NFC tag, which is compliant with: ISO/IEC 14443-4 (ISO-DEP) NFC Forum Type 4 Tag NFC-B protocol NDEF-formatted storage I’m using an iPhone 12 running iOS 18, and my app uses the Core NFC framework. Using NFCNDEFReaderSessionDelegate, I am able to successfully read the first NDEF message from the tag. However, the tag stores multiple NDEF messages, and I would like to access the others. Based on the tag’s specification, these messages are accessible via an NDEF file located at file ID 0xE104. To try and access this additional NDEF file, I attempted to use NFCTagReaderSession with the NFCTagReaderSessionDelegate, intending to issue APDU commands. However, the tagReaderSession(_:didDetect:) delegate method is never called, even though the tag is present and detected using NFCNDEFReaderSession. My questions: Does Core NFC on iOS 18 support issuing custom APDU commands to ISO 14443-4 (NFC-B) tags like the TI RF430? Is

Hi, I’m trying to migrate an App Clip from one main app (App A) to another (App B). These two apps are under the same Apple Developer Account (Team ID), and each has its own App Group. I’m wondering: 1. If I change the App Group configured in the App Clip’s entitlements, will this effectively allow the App Clip to be treated as part of App B? 2. Will this change allow me to reuse the existing App Clip Experiences (e.g., NFC/QR code invocation URLs) that were originally associated with App A? 3. Is such a change sufficient for Apple to treat the App Clip as migrated, or are there additional steps (e.g., changing the Bundle ID, resubmitting the App Clip Experience, etc.) required to complete the migration? I want to confirm whether switching the App Group and submitting a new App Clip with the new app is a valid and seamless way to perform the migration. I understand App Groups are typically used for data sharing, not experience binding — but I want to clarify if switching App Groups affects App Clip–m

Hi, there is a issue that iOS background NFC scanning will only provide a notification result, It need user click to enter my APP, can I have any method to enter my APP directly without user action ?

Hi I am implement my app with Core NFC , I found the module have their own UI , can I implement without the UI? we want the NFC scanning in background , not blocking the UI.

We have an app that uses the pass-presentation-suppression entitlement and calls requestAutomaticPassPresentationSuppression to prevent the Wallet app from being presented when the device is displaying a barcode to a barcode/nfc reader. This works as expected for users of the standard Apple Wallet app. However, it does not prevent third-party wallet apps from being launched, which hides the barcode and prevents it from being scanned properly. What options do I have to prevent third-party wallet apps from launching or interfering while our app is actively presenting a barcode?

I am getting report of a crash occurring, while doing a NFC HCE CardSession. The swift code is mostly the same as the example from the CardSession docs: @objc func deviceSupportsNFC (_ call: CAPPluginCall) { call.keepAlive = true let supportsNFCCallbackId = call.callbackId! Task() { guard NFCReaderSession.readingAvailable, CardSession.isSupported, // <-- line 86 await CardSession.isEligible else { print(TAG + HCE not allowed/available) var support = JSObject() support[supported] = false; let callback = bridge?.savedCall(withID: supportsNFCCallbackId) call.resolve(); callback?.resolve(support); return; } print(TAG + HCE allowed) var support = JSObject() support[supported] = true; let callback = bridge?.savedCall(withID: supportsNFCCallbackId) call.resolve(); callback?.resolve(support); } } Calling it from my plugin, to verify if (HCE) NFC is supported: if(await deviceInfoService.isIos()) { if(iosSupportEnabled === false) { console.log(NfcHceService:iOS but disabled); return; } this.requi
