how to hide a UITableView in Swift?

I have a single page iOS app (Swift 4, Xcode 9). It has a UITableView and a UIDatePicker. When the app loads only the table is visible to the user - it takes up the whole screen. When the user clicks "show date picker" I want the table to disappear so that the date picker comes into view. But I can't figure out how to do that. The table does disappear when I set tableView.isHidden = true, but the screen just goes blank, the date picker doesn't become visible. What am I doing wrong?

tableView.isHidden = true

(I know I could have a second view controller, a segue, etc, but I'm trying to keep it simple for now.)

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource

// data for the table view cells
let rowNames: [String] = ["foo", "bar", "show date picker"]

// cell reuse id (cells that scroll out of view can be reused)
let cellReuseIdentifier = "cell"

// hook this up from the storyboard
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var datePicker: UIDatePicker!

override func viewDidLoad()
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
makeTable()


override func didReceiveMemoryWarning()
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.


func makeTable()
// Register the table view cell class and its reuse id
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)

// (optional) include this line if you want to remove the extra empty cell divider lines
self.tableView.tableFooterView = UIView()

// This view controller itself will provide the delegate methods and row data for the table view.
tableView.delegate = self
tableView.dataSource = self


// number of rows in table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
return self.rowNames.count


// create a cell for each table view row
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell

// create a new cell if needed or reuse an old one
let cell: UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!

// set the text from the data model
cell.textLabel?.text = self.rowNames[indexPath.row]

return cell


// method to run when table view cell is tapped
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
print("You tapped cell number (indexPath.row).")
if indexPath.row == 2
tableView.isHidden = true

Here is an easy solution. Put two views into a stackView. One is hidden, one is not.
constrain the stack view to the frame of parent View.

add one line code: datePicker.isHidden = false

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
print("You tapped cell number (indexPath.row).")
if indexPath.row == 2
tableView.isHidden = true
datePicker.isHidden = false
