this is one example of transferring an amount of payment
I'm using the MVVM design pattern.
In the View.swift file
struct ContentView: View {
		@State var amount: String = ""
		
		var body: some View {
				VStack(alignment: .leading) {
						TextField("Enter amount...", text: $amount, onEditingChanged: { (changed) in
								print("amount onEditingChanged - \(amount)")
						}) {
								print("amount onCommit")
						}
						
						Text("Your amount: \(amount)")
				}.padding()
		}
}
//NumberFormatter in ViewModel.swift
assuming the variable amount = "USD1,234.57"
var numberInString = amount
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = NumberFormatter.Style.currencyISOCode
numberFormatter.locale = Locale(identifier: "en_US")
if let number = numberFormatter.number(from: numberInString) {
print("this is the final number:", number)
}
Result:
this is final number: 1234.57
