Automatically scroll to the top of a TextView control in swift

Question

I have a TextView control in my ViewController with a whole bunch of text in it. Too much to display at once.

When the controller loads the text that show is about in the middle of the complete text. I can scroll to the top or the bottom manually ok, but I want the text to be at the start of the whole text when the controller loads.

How do I do that?

You can set the contentOffset of your textView to programmatically scroll to the top:

textView.setContentOffset(.zero, animated: false)

Do it in your viewDidLayoutSubviews function, which is:

Called to notify the view controller that its view has just laid out its subviews.

override func viewDidLayoutSubviews() {
    textView.setContentOffset(.zero, animated: false)
}
