Why is Child Table View not sizing properly? - ios

Question

First off, please do not propose a "clever" solution suggesting I remove my TableViewController as a child view. Thank you.
Summary
I am adding a Tableviewcontroller programatically , as a child of a view with a fixed size of 216. I have been messing with constraints....and using the View Hierachy Debugger, I see the TableView always has a height of 852...which is basically the full size of the screen. How can I properly size the TableView to its containing view?

Below is a bunch of the code I am trying to use to constrain things...to no avail. Thank you.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var xyz: UIView!
override func viewDidLoad() {
super.viewDidLoad()
let child = UITableViewController()
xyz.addSubview(child.view)
self.addChild(child)
child.didMove(toParent: self)
//child.view.translatesAutoresizingMaskIntoConstraints = false
let safeArea = xyz.layoutMarginsGuide
var height = child.view.heightAnchor.constraint(equalToConstant: 292)
height = height.constraintWithMultiplier(2000)
height.isActive = true
child.view.topAnchor.constraint(equalTo: safeArea.topAnchor).isActive = true
child.view.bottomAnchor.constraint(equalTo: safeArea.bottomAnchor).isActive = true
child.view.leftAnchor.constraint(equalTo: safeArea.leftAnchor).isActive = true
child.view.rightAnchor.constraint(equalTo: safeArea.rightAnchor).isActive = true
}
}
extension NSLayoutConstraint {
func constraintWithMultiplier(_ multiplier: CGFloat) -> NSLayoutConstraint {
return NSLayoutConstraint(item: self.firstItem!, attribute: self.firstAttribute, relatedBy: self.relation, toItem: self.secondItem, attribute: self.secondAttribute, multiplier: multiplier, constant: self.constant)
}
}

Uncomment this line of code
child.view.translatesAutoresizingMaskIntoConstraints = false
