swipe left/right uiview without storyboard

Question

I want to swipe right to show another view and swipe left to get back to first view, Without using storyboard like this example:

Could someone show me how to do that with swift 4

Answer 1

I would assume that if you were to use a swipe gesture, you would do something like:

let swipeGesture = UISwipeGestureRecognizer()
let scrollView = UIScrollView()

swipeGesture.direction = .right
swipeGesture.addTarget(self, action: #selector(scrollToBeginning))

@objc func scrollToBeginning() {            
    scrollView.setContentOffset(.zero, animated: true)
}

Or using scrollView.scrollRectToVisible(CGRect(x: 0, y: 0, width: 1, height: 1), animated: true)
