Swift / how to use UITextView with dynamic height INSIDE UITableViewCell with dynamic height

Question

I'm using the following code to have the UITableViewCell have a dynamic height:

tableView.estimatedRowHeight = 155
tableView.rowHeight = UITableViewAutomaticDimension

And this code to have the UITextView change it's height based on the content.

extension NewUserTweetTableVC: UITextViewDelegate {

    func textViewDidChange(textView: UITextView) {
        let fixedWidth = textView.frame.size.width
        textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
        let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
        var newFrame = textView.frame
        newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
        textView.frame = newFrame    
    }
}

Once I change the text of the UITextView during runtime, the height of the UITextView changes, but the height of the UITableViewCell does not. How can I change that? Help is very appreciated.

Answer 1

Get programmatically height of textview...

let textView = UITextView()//your Text view
let sizeThatShouldFitTheContent = textView.sizeThatFits(textView.frame.size)
let height = sizeThatShouldFitTheContent.height

OR try this demo...
