Answer 1

You can change the UITableView height as per the contentSize as below:

Swift 2.2

tableView.frame = CGRectMake(tableView.frame.origin.x, tableView.frame.origin.y, tableView.frame.size.width, tableView.contentSize.height)

Swift 3 or 4+

tableView.frame = CGRect(x: tableView.frame.origin.x, y: tableView.frame.origin.y, width: tableView.frame.size.width, height: tableView.contentSize.height)

and make sure you write the above line in viewDidAppear method

You need to write the above line in viewDidLayoutSubviews also.

Swift 2.2

func viewDidLayoutSubviews(){
     tableView.frame = CGRectMake(tableView.frame.origin.x, tableView.frame.origin.y, tableView.frame.size.width, tableView.contentSize.height)
     tableView.reloadData()
}

Swift 3 or 4+

func viewDidLayoutSubviews(){
     tableView.frame = CGRect(x: tableView.frame.origin.x, y: tableView.frame.origin.y, width: tableView.frame.size.width, height: tableView.contentSize.height)
     tableView.reloadData()
}
