What would be the best way to display long passage with rich text style(multiple font styles, color, image).
Attached screen is similar to the kind of content I need to display.

- What's wrong with UITextView? It gives you the full Text Kit engine; that's as fast, powerful, and full-featured as it gets on Mac or iOS.matt– matt2018-02-03 22:59:30 +00:00Commented Feb 3, 2018 at 22:59
- 1How can we show the image, text with multiple fonts and styles? We could use attributedString for this but content size is too long(30 pages)Santosh Singh– Santosh Singh2018-02-03 23:02:01 +00:00Commented Feb 3, 2018 at 23:02
- 1@Fattie, I do have other solution like use DTCoreText(github.com/Cocoanetics/DTCoreText) kind of thing but for this, I have to restructure content again into HTML and display it, it will not lag in performance as well. I fear to create HTML for all content, not sure if it is the best solution.Santosh Singh– Santosh Singh2018-02-03 23:14:22 +00:00Commented Feb 3, 2018 at 23:14
- 1"We could use attributedString for this but content size is too long(30 pages)" I don't know why you say it's too long. You could lay it all out with PDF Kit if you want to paginate.matt– matt2018-02-03 23:35:30 +00:00Commented Feb 3, 2018 at 23:35
- 1@matt PDF is another option but again need to create formatted PDF.Santosh Singh– Santosh Singh2018-02-04 07:41:36 +00:00Commented Feb 4, 2018 at 7:41

The by far easiest approach is to convert your rich text to HTML and use a UIWebView to display it. The web view will take care of so many things:
- formatting
- scrolling
- loading fonts asynchronously
- loading images asynchronously

Good luck in finding an alternative that is sufficiently powerful and faster.

hi @SantoshSingh - this is the correct answer. You "shouldn't be" displaying crap like this in an app. if you have to do so - use a UIWebView!
Santosh Singh
Agreed, but as per my customer requirement, they have to display the long list of pages. There are many apps which use the long passage to display.

@Fattie Maybe UIWebView or they would have used NSAtttribuedString from HTML content for rendering. Isn't? NSAttributedString(data: self, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)

actually @SantoshSingh you may want to review this stackoverflow.com/questions/43723345 very complicayed and annoying issue! just FYI
