Hi all, I've write code for ios using CoreNfc provided by kotlin multiplatform: code:

private var session: NFCTagReaderSession? = null
private var tag: NFCISO7816TagProtocol? = null
override fun connect(iosMessage: String, actionDone: () -> Unit) {
    session = NFCTagReaderSession(NFCPollingISO14443, NfcReaderIos(readingInterface) { ok, mTag ->
        if (ok)
            tag = mTag
    }, null)
    session?.alertMessage = iosMessage
    session?.beginSession()
}
private class NfcReaderIos(
    private val readingInterface: NfcReading,
    private val itsOk: (ok: Boolean, tag: NFCISO7816TagProtocol?) -> Unit
) : NSObject(), NFCTagReaderSessionDelegateProtocol {
    override fun tagReaderSessionDidBecomeActive(session: NFCTagReaderSession) {
        Log.i("NFC TAG", "ACTIVE")
    }

    override fun tagReaderSession(session: NFCTagReaderSession, didDetectTags: List<*>) {
        val tag = didDetectTags.firstOrNull() as? NFCISO7816TagProtocol
        if (tag == null)
            itsOk.invoke(false, null)
        else {
            session.connectToTag(tag) {
                if (it != null) {
                    readingInterface.onTransmit("connected")
                    itsOk.invoke(true, tag)
                }
            }
        }
    }

    override fun tagReaderSession(session: NFCTagReaderSession, didInvalidateWithError: NSError) {
        Log.e("IOS ERROR", didInvalidateWithError.code.toString())
    }
}
