I'm trying to get a parallax effect similar to the home screen background. I've seen numerous examples of this working with a UIInterpolatingMotionEffect but I cannot get it to work on my iOS 14 devices (I've confirmed that the reduce motion setting is NOT enabled and the home screen background is moving like normal, so I know it works on my device).
I've tried variations of this code, adding it to a view / button / label and nothing happens... any ideas? Thank you!
let horizontal = UIInterpolatingMotionEffect(keyPath: "center.x", type: .tiltAlongHorizontalAxis)
horizontal.minimumRelativeValue = -50
horizontal.maximumRelativeValue = 50
let vertical = UIInterpolatingMotionEffect(keyPath: "center.x", type: .tiltAlongVerticalAxis)
vertical.minimumRelativeValue = -50
vertical.maximumRelativeValue = 50
let group = UIMotionEffectGroup()
group.motionEffects = [horizontal, vertical]
label.addMotionEffect(group)
