Instructions

• Hold camera up to a card and stay still until it gets recoginized and a picture gets taken.
• Hit Save, and the results should get processed.

Usage as Framework

There are 2 options to present:

Simply navigate to or present CardResultsView as a sheet or View:

var body: some View {
	CardFormView(colors: [.green, .blue, .black], completion: { cardDetails in 
        print("Card Number:\n\(cardDetails.number ?? "")")
        print("Expiry Date:\n\(cardDetails.expiryDate ?? "")")
        print("Name:\n\(cardDetails.name ?? "")")
        print("Name:\n\(cardDetails.cvcNumber ?? "")")
        print("Card Type:\n\(cardDetails.type.rawValue)")
        print("Card Industry:\n\(cardDetails.industry.rawValue)")
    })
}

Only the card reader view:

Add this code in your SwiftUI Main View underneath your main StackView/ScrollView/NavigationView:

.sheet(isPresented: $isShowingSheet) {
    CardReaderView() { cardDetails in
        self.cardDetails = cardDetails
        isShowingSheet.toggle()
    }
    .edgesIgnoringSafeArea(.all)
}

Create two state variables to handle sheet presentation and to hold the card details result from the closure:

@State private var isShowingSheet = false
@State private var cardDetails: CardDetails?

Add the UI Presentation logic of the CardDetails however you see fit:

if let cardDetails = cardDetails {
    Text("Card Number:\n\(cardDetails.number ?? "")")
    Text("Expiry Date:\n\(cardDetails.expiryDate ?? "")")
    Text("Name:\n\(cardDetails.name ?? "")")
    Text("Card Type:\n\(cardDetails.type.rawValue)")
    Text("Card Industry:\n\(cardDetails.industry.rawValue)")
}

Finally, present the CardReaderView by toggling the sheet (preferably from the closure of a button action):

Button { isShowingSheet.toggle() } label: { Text("Tap to Start Credit Card reading!") }
