UITextView inside of PopoverPresentationController doesn't response to its delegate method

Question

I am having problem making my UILabel to react to my UITextView by changing its textColor.

So when there over 250 words in my UITextView, my UILabel will should turn red. But it for some reason doesn't do it.

// class NewAppViewController: UIViewController, UITextViewDelegate...
    func textViewDidChange(_ textView: UITextView) {
            let characterCounts = commentTextField.text.characters.count
            wordCountLabel.text = String(250 - characterCounts)
            if (250 - characterCounts) < 0 {
                self.wordCountLabel.textColor = UIColor.red
                sendButton.isEnabled = false
            } else {
                sendButton.isEnabled = true
            }
     }

Did you specified delegate for uitextview? – Rafeek Jan 18 '17 at 06:47 — Rafeek, Jan 18 '17 at 06:47

You must have missed adding delegate. – Jan 18 '17 at 06:59 — , Jan 18 '17 at 06:59

I was being careless. I used UITextField by mistake. So now when I change back to UITextView, everything works fine.

Here is a picture.
