How to use new insertTextPlaceholder of ios 13?

Question

insertTextPlaceholder is available as of ios 13

I am trying to create a place holder for textview

 if #available(iOS 13.0, *) {
        msgBox.insertTextPlaceholder(with: CGSize(width: 210, height: 40))
    }

I don't see any placeholder created after this code

How can I use it properly?

What does `insertTextPlaceholder` do? UITextView does not contain this method. — Vladislav Markov, Apr 29 '20 at 09:54
Do you have a link to this? I think it does not contain. You can see it here: https://developer.apple.com/documentation/uikit/uitextview — Vladislav Markov, Apr 29 '20 at 09:58
Maybe you have an extension for UITextView. Or you use a subclass of UITextView. — Vladislav Markov, Apr 29 '20 at 10:00
No, I just use this let msgBox = UITextView() and msgBox.insertTextPlaceholder — Utku Dalmaz, Apr 29 '20 at 10:00
I found it - https://developer.apple.com/documentation/uikit/uitextinput/3213953-inserttextplaceholder. It does not have a description and it's an optional function. It's strange ). I will try to find out what it is. — Vladislav Markov, Apr 29 '20 at 10:05

First of all, I think you should not use it right now. Because the documentation are very poor. And UITextPlaceholder also has no interesting information.

I have not found anything useful about the function. Maybe it is not ready yet.

You should use Placeholder in UITextView.

What does the function do?

I found that it creates an empty space at the beginning of the UITextView with size that you pass to it.

1) UITextField (white field) without using insertTextPlaceholder:

2) UITextField with using insertTextPlaceholder:

It causes crashes. For example, if you add this:

let placeholder = textView.insertTextPlaceholder(with: CGSize(width: 100, height: 40))
textView.insertText("Test")

And type something in UITextView, you get this:
