Subview passes touches to subview beneath it - ios

Question

I have added a subview like so:
func showPlayerView2() {
self.view.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height - 56)
//let theView = myView
let theView = PlayerView()
theView.willMove(toParentViewController: self.navigationController)
self.navigationController?.addChildViewController(theView)
theView.view.isUserInteractionEnabled = true
theView.playPauseButton.isUserInteractionEnabled = true
self.navigationController?.view.bringSubview(toFront: theView.view)
self.navigationController?.view.addSubview(theView.view)
theView.view.frame = CGRect(x: 0, y: self.view.frame.maxY, width: 375, height: 56)
theView.didMove(toParentViewController: self.navigationController)
self.view.layoutSubviews()
}
PlayerView Has a button that is supposed to print something to the screen when pressed.
Even after setting isUserInteractionEnabled to true, it still does not register touches and they pass through to the view below it. I have looked at nearly every SO question relating to this and none of the answers have worked. What can I do to fix this?

Try this code if your looking for a common custom navigation menu
func setupPageNavigationBar(){
navigationController?.navigationBar.barTintColor = UIColor(red:1.00, green:0.22, blue:0.22, alpha:1.0)
navigationController?.navigationBar.translucent = false
let backButton = UIButton(type:.System)
backButton.setImage(UIImage(named: "img_back")?.imageWithRenderingMode(.AlwaysOriginal), forState: .Normal)
backButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let imgButton = UIButton(type:.System)
imgButton.setImage(UIImage(named: "img_logo_bar")?.imageWithRenderingMode(.AlwaysOriginal), forState: .Normal)
imgButton.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
navigationItem.leftBarButtonItems = [UIBarButtonItem(customView: backButton),UIBarButtonItem(customView:imgButton)]
backButton.addTarget(self, action: #selector(self.goBack), forControlEvents: .TouchUpInside)
let titleLabel = UILabel()
titleLabel.text = "SOME TITLE"
let titleLabel2 = UILabel()
titleLabel2.text = "Some text"
titleLabel.font = UIFont.boldSystemFontOfSize(15)
titleLabel.textColor = UIColor.whiteColor()
titleLabel.textAlignment = .Left
titleLabel2.font = UIFont.systemFontOfSize(11)
titleLabel2.textColor = UIColor.whiteColor()
titleLabel2.textAlignment = .Left
let titleView = UIView()
titleView.frame = CGRect(x: 0, y: 0, width: view.frame.width-90, height: 50)
//titleView.backgroundColor = UIColor.whiteColor()
titleView.addSubview(titleLabel)
titleLabel.translatesAutoresizingMaskIntoConstraints = false
titleView.addSubview(titleLabel2)
titleLabel2.translatesAutoresizingMaskIntoConstraints = false
//titleLabel.frame = CGRect(x: 0, y: 0, width: 134, height: 34)
let viewDict = ["titleLabel":titleLabel,"titleLabel2":titleLabel2]
titleView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|-0-[titleLabel]-0-|", options: NSLayoutFormatOptions(), metrics: nil, views: viewDict))
titleView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|-0-[titleLabel2]-0-|", options: NSLayoutFormatOptions(), metrics: nil, views: viewDict))
titleView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-5-[titleLabel(20)]-0-[titleLabel2(15)]", options: NSLayoutFormatOptions(), metrics: nil, views: viewDict))
//5+20+5+15+5
navigationItem.titleView = titleView
let homeButton = UIButton(type:.System)
homeButton.setImage(UIImage(named: "img_home")?.imageWithRenderingMode(.AlwaysOriginal), forState: .Normal)
homeButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
navigationItem.rightBarButtonItem = UIBarButtonItem(customView: homeButton)
homeButton.addTarget(self, action: #selector(self.gotoHome), forControlEvents: .TouchUpInside)
//CGRectMake()
}
And In viewControllers
override func viewDidLayoutSubviews()
{
self.setupPageNavigationBar()
}
