ReadMoreTextView is a good option for this purpose, with a few lines of code you can achieve this behavior.

@IBOutlet weak var aboutMessageTextView: ReadMoreTextView!
aboutMessageTextView.text = "your text"
let readMoreTextAttributes: [NSAttributedString.Key: Any] = [
     NSAttributedString.Key.foregroundColor: UIColor.systemBlue,
     NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 14)
   ]
aboutMessageTextView.attributedReadMoreText = NSAttributedString(string: " ... Read more", attributes: readMoreTextAttributes)
aboutMessageTextView.maximumNumberOfLines = 3
aboutMessageTextView.shouldTrim = true
