Making URL links attributed and clickable along with editable Textview in swift

Question

I want to make url links clickable inside TextView as well as making that text editable just as Notes app in iPhone.

here's what I attempted:

    txtVw.dataDetectorTypes = UIDataDetectorTypes.link
    txtVw.isSelectable = true
    txtVw.isEditable = false. // this is set to false to make link text tappable
    txtVw.linkTextAttributes = [.foregroundColor: UIColor.blue, .underlineStyle: NSUnderlineStyle.single.rawValue]
    txtVw.isUserInteractionEnabled = true
    txtVw.delegate = self

    let descTap = UITapGestureRecognizer(target: self, action: #selector(textViewTapped))
    descTap.numberOfTapsRequired = 1
    txtVw.addGestureRecognizer(descTap)

    @objc func textViewTapped(_: UITapGestureRecognizer) {
     txtVw.dataDetectorTypes = []
     txtVw.isEditable = true
     txtVw.becomeFirstResponder()
    }

Issue here is if I set isEditable property true, link is not formatted and remaining text if not editable. I want to achieve same things as we have in iPhone notes app. Have anyone come across this scenario? Any help would be appreciated.

First you need to have textView instead of Textfield. They apply below programmatic way for setting color or styling.

 let attributedString = NSMutableAttributedString(string: "I understand and agree to the Terms of Service.", attributes: [
              .font: UIFont.systemFont(ofSize: 12.0, weight: .regular),
              .foregroundColor: UIColor.errorColor,
              .kern: 0.0
            ])
            attributedString.addAttribute(.link, value: "https://policies.google.com/privacy?hl=en-US", range: NSRange(location: 30, length: 17))
            self.termOfServiceTextView.linkTextAttributes = [NSAttributedString.Key.foregroundColor.rawValue: UIColor.errorColor]
            attributedString.addAttribute(.underlineStyle, value: 1, range: NSRange(location: 30, length: 17))
            self.termOfServiceTextView.attributedText = attributedString

Now for Making it editable and clickable need to set from storyboard like: Just check Editable, Selectable options.
