Center UIView in container without jumping - swift

Question

I have this structure:
container (UIView)
Header (UIView)
TableView
CollectionView
CollectionView
CollectionView
When a favorite button is pressed I want a view to be displayed on top of everything and to be centered. Whenever it is added when the tableView has not been scrolled, it works fine. However, when added after it has been scrolled the whole layout kind of jumps into place. The more scroll, the more jumping. Visual representation of the layout:

The view is loaded from a xib and centered in its container. The view height and width anchors are already set (and translatesAutoresizingMaskIntoConstraints to false). Here is the configure method of the view to be centered.
public func configure(viewToCenterItselfInside: UIView) {
self.centerXAnchor.constraint(equalTo: viewToCenterItselfInside.centerXAnchor).isActive = true
self.centerYAnchor.constraint(equalTo: viewToCenterItselfInside.centerYAnchor).isActive = true
UIView.animate(withDuration: 0.5) {
self.alpha = 1
}
DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(1500)) {
UIView.animate(withDuration: 0.5, animations: {
self.alpha = 0
}) { (_) in
self.removeFromSuperview()
}
}
}
Here is the code when the view is loaded
if let addedFavorite = Bundle.main.loadNibNamed("ConfirmationView", owner: nil, options: nil)?.first as? ConfirmationView {
view.addSubview(addedFavorite)
addedFavorite.configure(viewToCenterItselfInside: view)
}
In addition to trying to solve it with constraints I've also tried centering it using self.center = viewToCenterItselfInside and messing around with the UIScreen.main without any results. Any ideas?
