Button is not clickable in a child viewcontroller - ios

Question

I am trying to make a side menu which reacts to a hamburger icon clicked.
I created another storyboard with a ViewConroller which contains the TableView in it.
I created a ViewController for this storyboard ViewController.
In the First ViewController (which is not a container), I have the following code:
var menuVC: UIViewController!
var isExpanded = false
#IBAction func MenuTapped(_ sender: UIButton) {
isExpanded = !isExpanded
showMenuVC(shouldExpand: isExpanded)
}
func showMenuVC(shouldExpand: Bool) {
if shouldExpand {
// show menu
if menuVC == nil {
print ("ONLY ONCE")
let storyboard = UIStoryboard(name: "Menu", bundle: .main)
menuVC = storyboard.instantiateViewController(withIdentifier: "MenuSB") as! MenuVC
menuVC.view.frame = self.view.frame.offsetBy(dx: view.frame.width, dy: 0)
menuVC.willMove(toParent: self)
self.view.insertSubview(menuVC.view, at: 0)
self.addChild(menuVC)
menuVC.didMove(toParent: self)
}
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 0.8, initialSpringVelocity: 0, options: .curveEaseInOut, animations: {
self.view.frame.origin.x = 80 - self.view.frame.width
}, completion: nil)
} else {
// hide menu
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 0.8, initialSpringVelocity: 0, options: .curveEaseInOut, animations: {
self.view.frame.origin.x = 0
}, completion: nil)
}
}
The thing is, the TableView is not responding to anything. Not scrolling, not clicking. I also tried a UIButton and it is not clickable.
The problem is, that the first ViewController is active while the MenuVC is not.
It is important to have both of them active, since the hamburger icon in the first ViewController closes the menu, but I need the MenuVC to be active as well.
Any thoughts?

Try to replace this line:
self.view.insertSubview(menuVC.view, at: 0)
with this:
self.view.addSubview(menuVC.view)
since I have no idea about the subviews you have in self.view, because there might be some views on top of your menu which have isUserInteractionEnabled set to true
