Answer 1

Solution in swift 3

Step 1. Set the top, bottom, leading and trailing constraints (do not make it constant height, but do set a constant height constraint as of now). Now we gonna change this height dynamically based on the number of cells and its height.

Step 2. Drag an outlet of that height constraint to the class, and copy this function anywhere in the class.

    func adjustHeightOfTableview() {
    let height: CGFloat = tableview.contentSize.height
    self.outLetOfTheHeightConstraint.constant = height

}

Step 3.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
    DispatchQueue.main.async {
            self.tableview.reloadData()
            self.perform(#selector(self.adjustHeightOfTableview))
        }
}
