“nfc”

are you trying to make something that uses Apple wallet? if so, I would start at about 15 minutes into this - https://developer.apple.com/wwdc18/720 session. if you are trying to do something within your app, you can’t do NFC passes without Apple Wallet, but you can make a QR code. here is a example function that generates a QR code from a string: func generateQRCode(from string: String) -> UIImage? { ttlet data = string.data(using: String.Encoding.ascii) ttif let filter = CIFilter(name: CIQRCodeGenerator) { ttttfilter.setValue(data, forKey: inputMessage) ttttlet transform = CGAffineTransform(scaleX: 3, y: 3) ttttif let output = filter.outputImage?.transformed(by: transform) { ttttttreturn UIImage(ciImage: output) tttt} tt} ttreturn nil } after you have that function, you use it like this: let image = generateQRCode(from: i am going to be so helpful to st0321!) that generates a QR code with the text i am going to be so helpful to st0321! and gives it to you as a UIImage.

If you mean can you communicate with the mobile phone SIM card, I believe not. You can use CoreNFC to exchange arbitrary APDUs with a JavaCard applet via NFC, though.

Hello may you please advice how were you able to use an NFC tag emulated in a device ?? and if there is a link or an app you used can you please share.

I have submitted a feature enhancement request on Feedback Assistant last year. It has been slow, but we already sent chip implants to Apple Engineers and private documents of how this chips work. They have everything to make the necessary changes. We have not hear back from Apple NFC Engineers since a while ago. Last word we had was that they needed an example data for the chip and what to expect from the chip. We have provided that and still waiting for their response on Feedback Assistant. We are still waiting and periodically messaging them to see if there are some news.

NFC

Yes, app clips be invoked using NFC. Please see the app clips developer documentation - https://developer.apple.com/documentation/app_clips for additional details.

Hi there, Yes, what you describe is possible. You'd set up the app clip experience such that you register a generic URL, for example yourdomain.com. When a user invokes the app clip, for example from an NFC tag, you could encode info in the URL, for example, yourdomain.com/thing/otherthing/1234, and when the user allows the app clip to launch in the app clip card, you'd get the whole URL on launch. The session Configure and Link Your App Clips - https://developer.apple.com/videos/play/wwdc2020/10146 goes into more detail. The developer docs also describes this in Configuring Your App Clip's Launch Experience - https://apple.com/documentation/app_clips/configuring_your_app_clip_s_launch_experience and Responding to Invocations - https://apple.com/documentation/app_clips/responding_to_invocations.

CoreNFC is supported on iPhone7 and later phones. iPads do not have an NFC radio.

0x35 is the Command code of the Authenticate command and 0x20 is the Request Flag per ISO15693 specification. You should specify the necessary flag setting using the NFCISO15693RequestFlag parameter. The authenticate function signature reflects the definition of the Authenticate command in the specification. Please consult to the ISO15693 specification for the full details. In iOS 14 Core NFC also offers sending custom command (https://developer.apple.com/documentation/corenfc/nfciso15693tag/3043799-customcommand). At this point I would recommend you to open a new Bug Report via Feedback Assistance. Attached a sample project illustrating the issue and attach related device log with indication of approximate timestamp when this issue occurs.
