In a string with just numbers and commas how do I convert that into a double

So I have a string with just numbers and commas. for example "1,233,323.32"(String) but I want to convert that to 1233323.32(double).

Solution

  • Swift 4: So basically we have a string with commas and we just remove all the commas in the string and then we use NumberFormatter to convert it to a double. 

    var newDouble = 0.0
var string = ""
string = textField.text?.replacingOccurrences(of: ",", with: "", options: NSString.CompareOptions.literal, range: nil) ?? ""
let myDouble = NumberFormatter().number(from: string)?.doubleValue
newDouble = myDouble ?? 0.0

    This code only works properly if there are only numbers and commas.
