I have given constraint of left v

Answer 1

This is how I worked out.

1) Set no. of lines to 0.

2) Set LineBreakage.

3) Add Constraints.

4) Change vertical content hugging priority.

5) On ViewDidLoad:

override func viewDidLoad() {
    super.viewDidLoad()

    self.sampleTableView.estimatedRowHeight = 600.0;
    self.sampleTableView.rowHeight = UITableViewAutomaticDimension;

    self.sampleTableView.setNeedsLayout()
    self.sampleTableView.layoutIfNeeded()
}

6) On TableView Custom Cell:

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code

    sizeToFit()
    layoutIfNeeded()
}
