style.lineSpacing = 24 // change line spacing between paragraph like 36 or 48
style.minimumLineHeight = 20 // change line spacing between each line like 30 or 40
attrString.addAttribute(NSParagraphStyleAttributeName, value: style, range: NSRange(location: 0, length: stringValue.characters.count))

attrString.addAttribute(NSBackgroundColorAttributeName, value: UIColor.red, range: NSRange(location: 0, length: stringValue.characters.count))

label.attributedText = attrString
