Set UITableView’s height to the height of its content with Auto Layout

by

You have to override updateViewConstraints() in your UIViewController and set the height constraint’s constant to tableView.contentSize.height:

override func updateViewConstraints() {
    tableHeightConstraint.constant = tableView.contentSize.height
    super.updateViewConstraints()
}

Then you have to make sure that Label2 has a top constraint that is greaterThanOrEqual to the table view’s bottom. And you also have to change the table view’s height constraint’s priority from Required to High to avoid conflicting constraints when the table view’s contentHeight is larger than the available height.
