remove \\u{e2} characters from string

Question

I copied mobile number from contact . I got it like \"8008708600\\u{e2}\" . I wish to remove \\u{e2} from string. String is copied with exponent character

Answer 1

I made a function for help:

public func formatContactsPhoneNumber(number: String) -> String {
    var buffer = ""
    for (i, char) in number.unicodeScalars.enumerated() {
        guard CharacterSet.decimalDigits.contains(char) else {
            continue
        }
        buffer.append(number[i])
    }
    return buffer
}

It's work well for me.
