How can I add ParallaxEffect without UIInterpolatingMotionEffect class

Question

how can i do a parallaxeffect without the UIInterpolatingMotionEffect class. Only with the Acceleration in the iPhone? I want the Effect when you tilt your phone up that the image goes up to. Just normal parallaxEffect

I've tried this:

func setupParallax() {
        let motion = CMMotionManager()
        motion.startAccelerometerUpdates()
        parallaxImage.frame.origin.x = CGFloat((motion.accelerometerData?.acceleration.x)!)
        parallaxImage.frame.origin.y = CGFloat((motion.accelerometerData?.acceleration.y)!)
    }

Use Core Motion. Ideally your motion manager’s reference frame should be CMAttitudeReferenceFrame.xArbitraryCorrectedZVertical, so that you can obtain the current attitude with respect to the starting attitude by calling multiply(byInverseOf:). To do so, run a repeating Timer and poll your motion manager’s device motion to get its attitude. Now use that to adjust the transform of your view.
