text changed event in UITextView

Question

I have

@IBOutlet weak var messageTextView: UITextView

and I want that when there is a change inside the text then print to console: blabla.

I tried to add the following function, but when I change the text nothing happens:

func textViewDidChange(_ textView: UITextView) {
    switch (textView) {
        case messageTextView: print("blabla")
        default: break
    }
}

@Kamran IMO, the question you linked is of worse quality than this one (no code provided in the one you linked), I'd recommend marking that question as a dupe of this one instead. — jrh, Jul 08 '19 at 00:01
@jrh I linked that question to read the answer that has a fix for this question. — Kamran, Jul 08 '19 at 04:43

You need to set the delegate inside viewDidLoad

textView.delegate = self

//

class ViewController: UIViewController , UITextViewDelegate  {
