Hello iPhone xs for testing XCode 15.3 I've successfully managed to select the AID and send other commands to a SmartCard using the following code: class NFCReader: NSObject, ObservableObject, NFCTagReaderSessionDelegate { func startNFCSession() { session = NFCTagReaderSession(pollingOption: [.iso14443], delegate: self, queue: nil) session?.alertMessage = Hold your iPhone near the NFC tag. session?.begin() // Start the session } func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { guard let tag = tags.first else { // Safely unwrap the first tag session.invalidate(errorMessage: No SmartCard detected.) return } session.connect(to: tag, completionHandler: { (error: Error?) in if let error = error { session.invalidate(errorMessage: Unable to connect to SmartCard: (error.localizedDescription)) return } switch tag { case let .iso7816(iso7816Tag): self.sendAPDUCommandSelect(to: iso7816Tag) self.sendAPDUCommand_2(to: iso7816Tag) default: print(Not iso7816 type) // Update the Swif

We have identified an issue on iOS 18 and iOS 18.1 (developer beta) where App Clips invoked via NFC or QR codes without a pre-configured Advanced App Clip experience (aka they should be using the Default App Clip Experience) are not functioning as expected. This issue is specific to iOS 18, as the behavior works correctly on iOS devices running 17.x. Steps to Reproduce: Set up two scenarios: One scenario where an App Clip has a pre-configured advanced app clip experience (with metadata such as title, subtitle, image). Another scenario where the App Clip is invoked without any pre-configured experience (should use the default App Clip experience). On an iOS 18 or iOS 18.1 device: For the default App Clip experience (no pre-configured advanced app clip experence): Scan the NFC tag when the phone is locked. Scan the NFC tag when the phone is unlocked. Scan the QR code. For the pre-configured App Clip experience: Perform the same tests (NFC and QR code scans). Test the same sce

I have AppClip set up in AppStoreConnect and it is activated when read by NFC. After trying several times, sometimes the AppClip card does not show up. (I don't think it's a communication speed issue as it doesn't show up after some time). As for the cards, we are only aware of the AppStroeConnect settings. I tried changing the image file of the card to one with a reduced size, but that did not completely resolve the issue. If you have anything to investigate to resolve the issue, I would appreciate it if you could let me know.

I keep seeing this in the Xcode when I launch my app: -[NFCTagReaderSession beginSessionWithConfig:]:468 error:Error Domain=NFCError Code=203 System resource unavailable UserInfo={NSLocalizedDescription=System resource unavailable}, errorCode: 0xcb Initially, the device was working with NFC. Now on multiple complete restarts of my app, the System resource is still not available. If I lock the screen and reenter iOS again, the problem persists. Rebooting the device appears to get it working again. I suspect this is only happening on iPhone 15 and iOS 18.01. My other devices I have do not exhibit the problem. I'd wager some service in the OS has crashed? There also appears to be limitation on renewing nfc sessions. Similar problems on iPhone 16 to what I experienced on iPhone 15. I don't know what they did with iPhone 15 and 16 but the NFC has really deteriorated for longer sessions. Seems the newer Apple HW is worse at NFC than my iPhone 11. Just providing feedback. The devi

I am trying to transfer data from one device to another using NFC. I'm trying to figure out if this is possible, I downloaded apple's sample project about CoreNFC, I was able to read NFC Tags (it wasn't a real NFC Tag, rather it was an NFC Tag emulated with an android device). Can I use my iPhone to emulate an NFC Tag to transfer data to another iPhone or Android device?

Hi, we are trying to get or set the NFC UID when doing HCE CardSession emulation, but can't find any way to either get the chip UID used in a session, or set it beforehand. Is that possible with a normal HCE CardSession eventStream received ADPU event? Or is another framework/product needed for this? We've done a Interoperability request (INTEROP-214), which lead us to using HCE. Our usecase is specifically interacting with EV chargers, that only support using the chips UID for identification. Can Apple Pay / Wallet be an alternative to do such low level handling?

When I am trying Write Virtual NFC from my iOS app the wallet app is open everytime. I just want to write the NFC tag data to RFID reader please help me with that.

I'm trying to read a tag generated by my app that emulates event input tags; in my NFC reader app and I get this error: <NSXPCConnection: 0x300a108c0> connection to service with pid 62 named com.apple.nfcd.service.corenfc: Exception caught during decoding of received selector didDetectExternalReaderWithNotification:, dropping incoming message.
