Full Tutorial

Preparation

1. Add to your project via Package Manager.

2. Add Near Field Communication Tag Reading (aka NFC) into the Project's Combilities.

3. Add NFC Privacy into Info.plist

Basic Usage

1. Import first.

import SwiftNFC

2. Add ObservedObject before body or any some View.

Read

@ObservedObject var NFCR = NFCReader()

Write

@ObservedObject var NFCW = NFCWriter()

Functions

func read() {
    NFCR.read()
}
func write() {
    NFCW.msg = NFCR.msg
    NFCW.write()
}

Reactive Properties

Both NFCReader and NFCWriter classes use @Published properties for automatic SwiftUI view updates:

NFCReader Properties

• startAlert - Alert message shown when scanning starts
• endAlert - Custom alert message after scanning (optional)
• msg - Decoded NFC message content (updates after scan)
• raw - Raw NFC data with type, identifier, and payload information

NFCWriter Properties

• startAlert - Alert message shown when writing starts
• endAlert - Custom alert message after writing (optional)
• msg - Content to write to the NFC tag
• type - Record type: "T" for text (default) or "U" for URI

These properties automatically trigger view updates when changed, enabling seamless SwiftUI integration with two-way bindings:

// Example: Bind to a TextField
TextField("Message", text: $NFCW.msg)

// Example: Display scan results
Text(NFCR.msg)
