Swift 4.2 and Xcode 11 Using TextView it's much easy

func setupContactUsInTextView() {
    let text = NSMutableAttributedString(string: "Contact us at email ")
    text.addAttribute(NSAttributedStringKey.font,
                      value: UIFont.systemFont(ofSize: 17),
                      range: NSRange(location: 0, length: text.length))

    let interactableText = NSMutableAttributedString(string: "contact@abc.com")
    interactableText.addAttribute(NSAttributedStringKey.font,
                                  value: UIFont.systemFont(ofSize: 17),
                                  range: NSRange(location: 0, length: interactableText.length))


    interactableText.addAttribute(NSAttributedStringKey.link,
                                  value: "contact@abc.com",
                                  range: NSRange(location: 0, length: interactableText.length))


    text.append(interactableText)


    contactUsTextView.attributedText = text
    contactUsTextView.textAlignment = .center
    contactUsTextView.isEditable = false
    contactUsTextView.isSelectable = true
    contactUsTextView.delegate = self
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    print("open website here...")
    return false
}
