Reply to Can't install app to iPad when Required Device Capability has NFC?
Resolved this issue with these configuration. In the project Signing & Capabilities, add Capability Near Field Communication Tag Reading In the project Build Phases, the Link Binary With Libraries” section, add the CoreNFC.framework, and then mark it as Optional. In the project Info, add Privacy - NFC Scan Usage Description = Use NFC Do not add Near Field Communication to Required Device Capability item (this cause Incompatible hardware on iPad) Use NFC feature only if UIDevice.current.userInterfaceIdiom == .phone in program. Hope this helps, Thank you.

Reply to NFC Core UI Issue: UI Becomes Unresponsive After Switching Between Landscape and Portrait Modes
This sounds like it could be an issue with the system's NFC UI, and we would like you to file a bug report about this. Don't forget to include as much information as you can about the cases you see this problem with. In your case a video or images showing the distortion would be very helpful. To file a bug report, you can use the Feedback Assistant. Once you open the bug report, please post the FB number here for my reference. If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why? Argun Tekant /  DTS Engineer / Core Technologies

NFC Core UI Issue: UI Becomes Unresponsive After Switching Between Landscape and Portrait Modes
I've encountered a consistent issue with iOS NFC Core UI where the app's user interface becomes unresponsive or visually distorted after scanning an NFC tag in landscape mode, dismissing the NFC UI, and then attempting to scan in portrait mode. Steps to Reproduce: Open an NFC-enabled app that uses iOS NFC Core UI. Start an NFC scan while holding the device in landscape mode. Dismiss the NFC scanning UI. Switch the device to portrait mode and initiate another NFC scan. Observe the UI, which often appears distorted or becomes unresponsive.

CoreNFC - CPLC Data via APDU
Hi, any help is appreciated please, many thanks in advance ! In my python script, I can get the CPLC data of a smartcard with the APDU: 80 CA 9F 7F 00. But on the iOS side with CoreNFC, the same exact APDU and card is giving a response of 0x6D00. Was wondering possible causes of this, or if I'm overlooking an error in my code: import SwiftUI import CoreNFC struct ContentView: View { @State private var responseText: String = Response will appear here. @State private var nfcSession: NFCTagReaderSession? @State private var nfcDelegate: NFCDelegate? var body: some View { VStack { Text(responseText) .padding() .multilineTextAlignment(.center) Button(Start NFC Session) { startNFCSession() } .padding() .background(Color.blue) .foregroundColor(.white) .cornerRadius(10) } .padding() } func startNFCSession() { guard NFCTagReaderSession.readingAvailable else { responseText = NFC not supported return } let delegate = NFCDelegate(responseText: $responseText) nfcDelegate = delegate nfcSession = NFCTagRead

Reply to Can My App Use/emulate iPhone as an NFC Tag for Tap-to-Interact with the new update??
While it is currently, and with iOS 18.1 would be possible for an app to emulate an NFC tag, these are reserved for very specific use cases and not available to be used for arbitrary tag emulation. You can read about the capabilities and requirements for these use cases in the following documents: NFC & SE Platform for secure contactless transactions HCE-based contactless transactions for apps in the European Economic Area (EEA) At this time, no other use cases are supported.

Can My App Use/emulate iPhone as an NFC Tag for Tap-to-Interact with the new update??
Hello, I’m developing an app and want to explore the possibility of using an iPhone to emulate an NFC tag. Specifically, I’m interested in enabling one iPhone to act as an NFC tag that another iPhone can read, creating a tap-to-interact experience within my app. Is this functionality supported by current iOS APIs, or is it something that might be available in the next update for iOS 18.1 which is supposedly unlocking iPhone NFC chips? If not, are there any workarounds or third-party solutions that can achieve this such as bluetooth low energy (BLE) maybe? Any insights or guidance on how to implement this feature would be greatly appreciated. Thank you!

Can I sync my Apple Watch series 9 with the Huawei health app?
I bought an Apple Watch series 9, but I'm not very comfortable using the standard Apple health app, so I decided to try huawei health. The question is, is there any way to sync your Apple Watch with this app? I am also interested in how to find out the temperature on the wrist in degrees, and not how much it deviates from the norm? And now a question for Apple personally: why should I LIE that I am 18 years old (I am 16 years old) in order to measure the oxygen level in my blood? Why am I paying 36,000₽ ($403.47) for two non-working chips?! One of them is NFC, and the second is a second-generation ultra wideband chip, which are vital for me personally! Don't be like Samsung, they can't find headphones at all through their locator if the case is closed, and you tell Apple that just use ultra wideband, users from Russia just laugh at you when you mention this chip, I've been looking for my headphones for 3 days. I'm sorry if it's too aggressive at the end, it just doesn't suit me that I'm paying a lot

What is the reason for system being not eligible for CardSession APIs from CoreNFC?
I am working on a simple app that communicates using APDUs as Apple opened up NFC and HCE Entitlement for the EU market. I got the entitlement for my developer account, I have the entitlements available in the NDEF and TAG values and also added proper AID value. Also added SKExternalPurchase and SKExternalPurchaseLink keys to the Info.plist. When I check the CardSession.isSupported and NFCReaderSession.readingAvailable they come out to be true. But when checking the CardSession.isEligible it's value is false. When checking the documentation for it, it simply says that A property that indicates whether the current device supports card session functionality. How can check the issue with current system?

Reply to NFC App's readerSession(didDetect) Not Executing
If I understand your use case correctly, with your Write function you are trying to have your app become an NDEF tag. In other words you are trying to emulate an NDEF tag. Unfortunately, this is not possible. As the name suggests a readerSession is just that. It can read NFC tags. I believe you may have misunderstood the use case for writing to an NDEF tag. While it is possible to use the writeNDEF(_:completionHandler:) to write to an NDEF tag, that is all this function can do - write a payload to an existing NDEF tag. This function does not turn your app into an NDEF tag. What you are trying to do is called Host Card Emulation, and this is only available for apps that fit specific requirements. You can read the rules and requirements at HCE-based contactless transactions for apps in the European Economic Area (EEA) and follow the steps in the documentation to apply if, and only if your conditions and use case matches the stated requirements.

iOS 18.1 NFC/SE APIs - access to applet deployed onto SE
Apple is opening up NFC and SE APIs to developers on iOS18.1 in certain territories. The documentation mentions that NFC & SE Platform partners can submit an applet for installing into the Secure Element. When a request is made by an iOS app to provision a card, the signed applet corresponding to the card scheme will be downloaded into the iPhone and personalised by the platform partner servers. Would it be possible to access the applet through SE APIs? If yes, would the access be open to any iOS app that has the granted HCE entitlement to the card scheme (e.g AIDs). Or is access limited to only the iOS app that create/published the applet? From the document (excerpt below), it looks like any iOS app with the HCE entitlement to the card scheme would be able to use the applet. However it also mentions lifecycle management where an iOS app can delete the applet (or credential). Would be interested in getting insight into this.

NFC App's readerSession(didDetect) Not Executing
Hello, (I apologize for my poor English.) I’m developing an iPhone application that uses NFC, but it’s not working as expected. I would appreciate your help in resolving the issue. This app uses Core NFC API and is designed to write the URL of my blog onto the NFC tag of another smartphone and automatically open the browser. This app is installed on my iPhone but is not uploaded to the App Store. In this app, I have implemented the following functions using the NFCNDEFReaderSessionDelegate: NFC Program(Swift) (1). readerSessionDidBecomeActive (2). readerSession(didInvalidateWithError) (3). readerSession(didDetectNDEFs) (4). readerSession(didDetect) When I run this app, I can confirm that the (1) function is called, but when I bring another smartphone close to my iPhone, the (4) function, which should be triggered, does not execute. Also, (3) does not execute either. How can I ensure that the fourth(4) function is executed? For reference, the iOS versions of the iPhones are
