Force character inclusion in string displaying

I am manually displaying a string printing a USD price as follows:

let price : String = String(format:"%.2f", finalPrice)
priceLabel.text = String("$" + price)

Is there any way to add the , every 3 digit without using NumberFormatter? I couldn't find the corresponding format code for that if any.

Solution

  • I would recommend to USE the NumberFormatter.

    Your code would look like this:

    let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.locale = Locale(identifier: "en_US")
formatter.maximumFractionDigits = 2
formatter.groupingSeparator = ","
priceLabel.text = formatter.string(for: price)
