Answer 1

If you want your UITextView detect link, phoneNumber, address, calendarEvent or simply detect all types than use UIDataDetectorTypes .

let yourstring = "Check Google search. www.google.com"

// Update UITextView font and font size.
textVw.font = UIFont(name: "HelveticaNeue", size: 25)

// Make web links clickable
textVw.isUserInteractionEnabled = true
textVw.isSelectable = true
textVw.isEditable = false
textVw.dataDetectorTypes = UIDataDetectorTypes.link

// Update UITextView content
textVw.text = yourstring

// Update hyperlink text colour.
textVw.linkTextAttributes = [NSForegroundColorAttributeName : UIColor.blue, NSUnderlineStyleAttributeName : NSUnderlineStyle.styleNone.rawValue]

textVw is a object of UITextView as

@IBOutlet var textVw: UITextView!

You can also make text detectable from storyboard as below screenshot.

You can use this code to make your UITextField clickable and open a URL for example

 // This is the label
    @IBOutlet weak var label: UILabel!

override func loadView() {
    super.loadView()

    // here is where you make your label clickable 
    let tap = UITapGestureRecognizer(target: self, action: #selector(self.onClicLabel(sender:)))
    label.isUserInteractionEnabled = true
    label.addGestureRecognizer(tap)
}

// And here are the functions to open a URL 
func onClicLabel(sender:UITapGestureRecognizer) {
    openUrl(urlString: "http://www.google.com")
}


func openUrl(urlString:String!) {
    let url = URL(string: urlString)!
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    } else {
        UIApplication.shared.openURL(url)
    }
}
