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 SwiftUI view break } }) } } I encounter an issue when attempting to interact with the user for specific commands. I need to maintain the session active in the background while waiting for additional commands. However, upon closing the NFC dialog, I receive the NFCError Code=200 "Session invalidated by the user" error. My ideal use case: Button1: Initiates the connection and waits for the SmartCard to be presented. tagReaderSession() connects to the SmartCard and sends the AID. Button2: Sends APDU command 2. Button3: Sends APDU command 3. To proceed with clicking the other buttons, the NFC dialog must be closed, but doing so invalidates the session with error 200. Is there a way to keep the connection valid in the background while waiting for additional commands?
