Using a negative number with a CurrencyFormatter in swit 4

I have a currency format func that looks like this:

func currencyFormat() -> NumberFormatter{
    let currencyFormatter = NumberFormatter()
    currencyFormatter.usesGroupingSeparator = true
    currencyFormatter.numberStyle = NumberFormatter.Style.currency
    // localize to your grouping and decimal separator
    currencyFormatter.locale = NSLocale.current
    return currencyFormatter
}

So when I use it like this:

currencyFormat().string(for: 20.34)   --> $20.34

Same goes if I send over a negative value

currencyFormat().string(for: -20.34)  -->  -$20.34

I don't want the negative sign to come back formatted with the currency

It works great but the issue I'm having is if I send it a negative decimal number, I get back the negative sign. Is there a way to drop that sign? Should I convert the decimal to positive before I send it over to the converter?

Ensure the number is positive before sending it through the currency formatter by taking the absolute value:

let number = -500
let positiveNumber = abs(number)

let formattedNumber = currencyFormat().string(for: positiveNumber)

This is the simplest and most readable way to do it.
