Unable to read custom NFC tags on iOS 16.0 (iPhone 13 Pro Max)
Hello, I'm trying to read custom NFC (13.56mhz) tags with my iPhone using an NFC app, but none of them seem to be working (I've tried the three most popular NFC apps). I am writing text to these tags using a RC522 connected to a Raspberry Pi. I know that my scanner is working because I can read and write text to tags. I know NFC on the iPhone is working because the scanner also detected the signal when I opened and activated Apple Pay. Besides that, I am using known-good tags (such as a hotel room key) that also work with my scanner but not my iPhone. Has anyone else encountered this issue? Is there a solution? Thanks.

Hello @larryr1. I'm not well versed in NFC, however reading the CoreNFC documentation, I see Using Core NFC, you can read Near Field Communication (NFC) tags of types 1 through 5 that contain data in the NFC Data Exchange Format (NDEF). and Your app can also write data to tags, and interact with protocol specific tag such as ISO 7816, ISO 15693, FeliCa™, and MIFARE® tags. Does your tag conform to these format requirements? —Jason.

CoreNFC - Empty ndefMessage when upgrading to iOS 16
After upgrading to iOS 16, the code below that I have to read the NDEF contents of an NFC Forum Type 2 Tag now returns an empty string. When running the same code on my iOS 15 device, this code works perfectly. When downgrading my iOS 16 device to iOS 15, this code works perfectly again. I can't find any documentation regarding changes made to CoreNFC in iOS 16 that would be affecting this, can anyone shed any light here please? func readerSession(_ session: NFCNDEFReaderSession, didDetect tags: [NFCNDEFTag]) { print(did detect) let str: String = nfcWriteContent if (tags.count > 1) { let retryInterval = DispatchTimeInterval.milliseconds(500) session.alertMessage = too_many_nfc_detected.localized() DispatchQueue.global().asyncAfter(deadline: .now() + retryInterval, execute: { session.restartPolling() }) return } let tag = tags.first! print(reading...) tag.readNDEF(completionHandler: {(ndefMessage: NFCNDEFMessage?, error: Error?) in var res = if (ndefMessage == nil) { // EVERY NFC SCAN ALW

Reply to [Issue] Automation forcing to tap on screen - application run command is not reacting to 'ask when run' unslide during connection or disconnection to Carplay
I got a new iPhone 14 Pro, and decided to use Shortcuts to log trips instead of having a trip logging app that drains my battery due to excessive location tracking, which is totally unnecessary for the tax purposes. The beginning and end point of any trip is all I need, not the whole detailed route on a map. I have 2 neat logging shortcuts, one for the departure and one for the arrival, both totally doing a perfect logging of my ODO meter that I store as a generic file. After each trips the name of that file gets updated by a voice input of the car’s ODO meter. Data gets logged in a text file. All data is separated with tabs, making it possible to import the text file contents into a Numbers file when needed. I am pretty stoked I got this far, and love the Shortcuts app! (I tested feeding the Numbers file directly, but the result isn satisfactory since it opens the app and I want all of the processes to run without imperative screen interaction.) Both shortcuts can be triggered flawlessly using Siri in Carpla

Reply to Apple Watch NFC Tags
I'd love to just touch my apple watch to a nfc tag to turn on the lights when I come home, or turn them off when I leave. Or a million other things that shouldn't require me to take my phone out of my pocket. No, HomePod is not even available here and even if it was it wouldn't be possible to put one in every single room.

NFC Host Card Emulation support
Hi, I am developing an iOS app in which the device(iPhone) needs to act as an NFC tag(conforming to ISO 14443) so that an NFC reader could read the information present in this virtual tag (like UID). How can I acheive this ? Does iOS supports NFC Host Card Emulation ?
