SwiftNFCClosureHandler

SwiftNFCClosureHandler is a Swift package for scanning NFC tags on iOS for your SwiftUI projects.

The scanned NFC data is returned as a Swift Data via closure. You can then massage the data to your specific needs.

How to

Once you import the Swift package to your project, this is what you can do:

import SwiftNFCClosureHandler

struct ContentView: View {
    // Declare a @StateObject for the SwiftNFCClosureHandler
    @StateObject var nfc: SwiftNFCClosureHandler = SwiftNFCClosureHandler()

    // Your button code
    ...
    Button(action: {
        nfc.begin(action: { data in
                if let string = String(data: data, encoding: .ascii) {
                    self.nfc_value = string
                }
            })
        }) {
            Text("Click to Scan")
        }
    ...

}
