UITextField decimal pad show dot instead of comma

How to show . instead of , symbol for decimal pad?

I found a few solution with using NSNumberFormatter, replacing string on the fly and extension of UIEnglishTextField, which should return localised textfield.

No of these solutions worked for me.

I mean for sure I can transform string, but is there a way to display right dot symbol.

It's out of topic, but this code works for me (SWIFT 5):

extension String {
    static let numberFormatter = NumberFormatter()
    var doubleValue: Double? {
        String.numberFormatter.decimalSeparator = "."
        if let result =  String.numberFormatter.number(from: self) {
            return result.doubleValue
        } else {
            String.numberFormatter.decimalSeparator = ","
            if let result = String.numberFormatter.number(from: self) {
                return result.doubleValue
            } else {
                return nil
            }
        }
    }
}
