macos - Set the placeholder string for NSTextView

Question

Is there any way to set the placeholder string for NSTextView like that in NSTextField? I have checked the property but couldn't find it. I have searched some questions but there isn't a proper explanation.

Swift 4

As it turns out, there already seems to be a placeholderAttributedString property in NSTextView that isn't exposed publicly. Thus, you can simply implement it in your own subclass and get the default placeholder behaviour (similar to NSTextField).

class PlaceholderTextView: NSTextView {
     @objc var placeholderAttributedString: NSAttributedString?
}

And if this property will be made available in the future, you only need to use NSTextView instead of this subclass.
