I have a scenario to change the color of single repeat characters '#' in a string just like as image shown below. I m using this code.

    let textTag = lblNewsTag.text
    let range = (textTag! as NSString).rangeOfString("#")
    let attributedString = NSMutableAttributedString(string:textTag!)
            attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor() , range: range)
    lblTag.attributedText = attributedString

In a nutshell... match the characters with a regex (or by any other means), get the **range** of each match and apply the desired attributes. – Alladinian Feb 08 '17 at 11:17
I have not implemented yet. – Salman Ghumsani Feb 08 '17 at 11:17
See updated Question @NiravD – Salman Ghumsani Feb 08 '17 at 11:21
`rangeOfString:` returns the FIRST parameter found. So your code should colorize only the first one. Use Regex, or simply look how to "loop" with `rangeOfString:` (plenty of question on SO about that). – Larme Feb 08 '17 at 11:24
