Swift UITableViewAutomaticDimension is not working

Question

I have got a table in my Swift project like this

var tableView: UITableView! 
tableView = UITableView()
tableView.dataSource = self
tableView.delegate = self
ta         


        

Answer 1

I had problems with constraints so here is what i did.
First i added heightForRowAt

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 100
}

Then i created a variable

let tableViewHeight  = postTexts.count*100

And put that in my height constraint

    tableView.anchor(PostsDiv.bottomAnchor, left:view.leftAnchor, bottom: nil, right: view.rightAnchor, topConstant: 40, leftConstant: 15, bottomConstant: 0, rightConstant: 15, widthConstant: 0,heightConstant: CGFloat(tableViewHeight))

And it works pretty well for me
