import UIKit

func convertCurrency( money : NSNumber, style : NSNumberFormatterStyle ) -> String {
    
    let numberFormatter = NSNumberFormatter()
    numberFormatter.numberStyle = style
    
    return numberFormatter.stringFromNumber( money )!
}

let value = 12345678.123

convertCurrency(value, style : NSNumberFormatterStyle.DecimalStyle)
convertCurrency(value, style : NSNumberFormatterStyle.NoStyle)
convertCurrency(value, style : NSNumberFormatterStyle.CurrencyStyle)

#=========== Output  ===================
