override func viewDidLoad() {

    imageView.layer.superlayer?.insertSublayer(pulsator, below: imageView.layer)
    ...

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

I hope this was resolved. Thanks @marciliojrs for your support!

I believe this should be centered by default as well, or at the very least customizable by the API.

I added this line and it set the position correctly:

pulsator.position = sourceView.layer.position

That way I didn't need to override that method out just to correct the position, not sure if there is ramifications to this method for other use cases but it worked as well in my case and isolated my code to a single method.

It might be nice to provided a convenience initialization method for the element, since drawing behind and center to another view is a common (most used?) use case. That could make the API more friendly for the norm

I've added the following code and that worked for me:
pulsator.position = CGPoint(x: yourView.bounds.width / 2, y: yourView.bounds.height / 2)

There's also a center property available, so this works too:
pulsator.position = yourView.center
