@rajdeep Thanks, the problem was solved.

@Chunngai, you may use matchTextExact with insets to get around this issue. Using the following style, you can achive the output below:

 let style = BackgroundStyle(color: .green, roundedCornerStyle: .absolute(value: 5), border: BorderStyle(lineWidth: 1, color: UIColor.blue),
                                    shadow: ShadowStyle(color: .red, offset: CGSize(width: 2, height: 2), blur: 1),
                                    heightMode: .matchTextExact, insets: UIEdgeInsets(top: -5, left: 0, bottom: -5, right: 0))

If you wish for the backgrounds to be merged as shown in the article, you can also use matchLine for heightMode.

I'll be fixing the matchText option in a future release to work better with lineSpacing. The key difference in matchText and matchTextExact is that the matchTextExact assumes the exact text height by default where as matchText keeps a little padding all around based on iOS string boundingRect logic. Since similar output can be achieved by matchTextExact with insets, I may also consider dropping matchText altogether.
