Getting Parallax through UIInterpolatingMotionEffect With Image Stationary in Swift

I am trying to get a parallax effect on an image in Swift.
Instead of the image changing when you tilt the phone back and forth, however, so you appear to be looking from a different angle--what I think of as a parallax effect--the image is just moving left, right, up down against the background as you tilt. This is not want I want. I want the image to remain stationary on the background. Can anyone suggest a way to get the parallax effect with the image stationary.
The image is a UIImageView in a tableviewCell. It is created in storyboard with an outlet and constrained in height, width (40pts each) and within cell.
Here is the parallax code:
func addParallaxToView(vw: UIView) {
let amount = 100
let horizontal = UIInterpolatingMotionEffect(keyPath: "center.x", type: .tiltAlongHorizontalAxis)
horizontal.minimumRelativeValue = -amount
horizontal.maximumRelativeValue = amount
let vertical = UIInterpolatingMotionEffect(keyPath: "center.y", type: .tiltAlongVerticalAxis)
vertical.minimumRelativeValue = -amount
vertical.maximumRelativeValue = amount
let group = UIMotionEffectGroup()
group.motionEffects = [horizontal, vertical]
vw.addMotionEffect(group)
}
It is called in the custom cell class with:
addParallaxToView(vw: cellImageView)
