How do I add padding to a substring of UITextView that is a NSMutableAttributedString (shown here highlighted in yellow)?

I currently have the attributed text (image 2) without any padding around the attributed text, but need to add some padding to it (image 3), which is some spacing around the highlighted text only (not the entire UITextView.

Here is a close-up comparing how the NSMutableAttributedString with/without padding (this padding should not apply to the rest of the text which unattributed):

Here's how I'm currently getting the text from the UITextView (after finding the range of text I want to highlight and storing the attributed text in attributedText):

var highlightedText = NSMutableAttributedString(string: "this text is highlighted")
let highlightedRange = NSRange(location: 0, length: highlightedText.characters.count)

highlightedText.addAttribute(NSBackgroundColorAttributeName,
                             value: UIColor.yellow, range: highlightedRange)

attributedText.replaceCharacters(in: highlightedRange, with: highlightedText)

@SNarula that seems to give padding around the whole `UITextView`, but I only want it around the attributed text? – user2560886 Dec 28 '16 at 06:03
@NiravD In the example, the padding add spaces on all sides of the attributed text in yellow (compare image 2 vs image 3), basically [padding like in CSS](http://www.mediaforma.com/uneminuteparjour/html5/images/raccourcissez-vos-styles-css-margin-et-padding-1.jpg) – user2560886 Dec 28 '16 at 06:07
In image 3 i don't believe it has extra space in between texts @user2560886 – Fay007 Dec 28 '16 at 06:13
they are just different font type, change the font family for ur attributed string and u will see the difference – Fay007 Dec 28 '16 at 06:14
@Fay007 I added another close-up image, which shows padding around the text – user2560886 Dec 28 '16 at 06:14
@Fay007 I need them to be the same size, but with some extra space around it, so the background doesn't hug the text – user2560886 Dec 28 '16 at 06:15
@Tj3n Thanks, I've added the example – user2560886 Dec 28 '16 at 06:32
Any luck finding a hack?! Or custom attribute is the only way out? – Chirag Shah Jul 04 '17 at 06:28
