So I'm using a TextField with a formatter, the issue is unless the user hits return that value is not captured which is causing some distress for users, even though I have added a label stating they should hit return, but in fairness it doesn't seem professional. How can I combat this issue? Is there a way in which I can capture the input as the user inputs data into the textfield, as well as formatting the input simultaneously?

This is my code:

  var currencyFormatter: NumberFormatter = {
        let val  = NumberFormatter()
        val.numberStyle = .currency
        val.currencyCode = "GBP"
        return val
    }()

   TextField("0", value: $viewModel.price, formatter: currencyFormatter)
   .foregroundColor(Color(SYSTEM_FONT_COLOUR))

Thank you.
