In swift, how do I do this?

Question

My English is not enough to search the question. So, I have to write here. My integer is 600000000 for ex. I want to convert it like this: 600,000,000. How do I do this?

extension Int {
    struct Number {
        static let formatter = NSNumberFormatter()
    }
    var addThousandSeparator:String {
        Number.formatter.groupingSeparator = "."
        Number.formatter.numberStyle = NSNumberFormatterStyle.DecimalStyle
        return Number.formatter.stringFromNumber(self)!
    }
}

let myInteger = 600000000
let myIntegerString = myInteger.addThousandSeparator  // "600.000.000"

I add this in view controller.swift, but there was an error: declaration is only valid at file scope. How do i fix it? Thanks! – Batuhan Kök Aug 19 '15 at 22:58
Just add this extension at the bottom of your view controller (outside your view controller) – Leo Dabus Aug 19 '15 at 23:00
