        let stringVariable = "Welcome @ location"

        var attributedString = NSMutableAttributedString(string:stringVariable)

        var attributedStringAnother = NSMutableAttributedString(string:"abc")


        attributedString.replaceCharactersInRange(NSRange(location: 8,length: 1), withAttributedString: attributedStringAnother)
