Usage

First, You have to define HorizontalParallaxScrollView object.

let view = UIView(frame: CGRect(x: ?, y: ?, width: ?, height: ?))
let item = HorizontalParallaxScrollViewItem(view: view,
                                            originOffset: CGPoint(x: 150, y: 80),
                                            acceleration: ParallaxAcceleration.invariable(CGPoint(x: 1, y: 1)),
                                            progress: { (parallaxView, view) in
                                                //...
                                            })

If you want, You can define a dynamic acceleration.

let dynamicAcceleration = ParallaxAcceleration.variable { (parallaxView, view) -> CGPoint in
                            let progressRatio = (parallaxView.contentSize.width - 3 * parallaxView.contentOffset.x) / parallaxView.contentSize.width
                            return CGPoint(x: 0.65 * progressRatio, y: 0.65 * (1 - progressRatio))
                          }

let view = UIView(frame: CGRect(x: ?, y: ?, width: ?, height: ?))
let item = HorizontalParallaxScrollViewItem(view: view,
                                            originOffset: CGPoint(x: 150, y: 80),
                                            acceleration: dynamicAcceleration,
                                            progress: { (parallaxView, view) in
                                                //...
                                            })

Second, Build a parallaxView.

let parallaxView = HorizontalParallaxScrollViewBuilder.setOption { (option) in
                        option.frame = CGRect(x: 0, y: 100, width: view.frame.size.width, height: view.frame.size.height - 100)
                        option.parallaxViewItems = [item] // You can add more items.
                        option.isPagingEnabled = false
                   }.build()
parallaxView.delegate = self //Optional
