let string = "Google"
let linkString = NSMutableAttributedString(string: string)
linkString.addAttribute(NSLinkAttributeName, value: NSURL(string: "https://www.google.com")!, range: NSMakeRange(0, string.characters.count))
linkString.addAttribute(NSFontAttributeName, value: UIFont(name: "HelveticaNeue", size: 25.0)!, range: NSMakeRange(0, string.characters.count))
textView.attributedText = linkString
textView.delegate = self
textView.selectable = true
textView.userInteractionEnabled = true
}

func textViewShouldBeginEditing(textView: UITextView) -> Bool {
return false
}
func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: …
