Swift move image from right to left than from left to right

Question

I want to make an animation that move a background image from right to left than left to right. I use this code but not works

        UIView.animate(withDuration: 5, delay: 0, options: .repeat ,animations: { () -> Void in
                imageView.transform = CGAffineTransform(translationX: -imageView.frame.width + self.view.bounds.width, y: 0)
                UIView.animate(withDuration: 5, delay: 1, options: .repeat ,animations: { () -> Void in
                    imageView.transform = CGAffineTransform(translationX: +imageView.frame.width - self.view.bounds.width, y: 0)

                })

            })

Answer 1

I solved with this

UIView.animate(withDuration: 30.0, delay: 0, options: [.repeat, .autoreverse], animations: {

                imageView.transform = CGAffineTransform(translationX: -imageView.frame.width + self.view.bounds.width, y: 0)

            }, completion: nil)
