Adding a container view to UISplitviewController

Question

I would like to add a container view to my UISplitViewController in such a way that its always in the center of the screen. My problem is that I have a master and detail so the container view can't really belong to either one. Right? I guess the main issue is how to display it when in allVisible mode (when both master and detail are shown).

Is this possible?

After some digging, the answer is YES and was somewhat embedded in the question: add the container view to the UISplitViewController which in and of itself is a containerView.

containerView = UIView()
containerView.backgroundColor = UIColor.green
containerView.alpha = 0.5
containerView.translatesAutoresizingMaskIntoConstraints = false

let spvcView = splitViewController!.view!
spvcView.addSubview(containerView)
NSLayoutConstraint.activate([
  containerView.leadingAnchor.constraint(equalTo: spvcView.leadingAnchor, constant: 50),
  containerView.trailingAnchor.constraint(equalTo: spvcView.trailingAnchor, constant: -50),
  containerView.topAnchor.constraint(equalTo: spvcView.topAnchor, constant: 50),
  containerView.bottomAnchor.constraint(equalTo: spvcView.bottomAnchor, constant: -50),
  ])

That's it!
