How To Create Animation of Segue perform and unwind segue? - swift

Question

i am working on application where i am trying to call controllers with animations
second view controller with animations
like when i call second controller with segue
second controller come from right and first controller start moving to left
like android push pop animations
i make some code
class SegueFromRight: UIStoryboardSegue {
override func perform() {
let src = self.source
let dst = self.destination
src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)
dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width*2, y: 0)
//Double the X-Axis
UIView.animate(withDuration: 0.25, delay: 0.0, options: UIView.AnimationOptions.curveEaseInOut, animations: {
dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
}) { (finished) in
src.present(dst, animated: false, completion: nil)
}
}
}
but from this code new controller come from right i need to move current controller to move left too
if anyone can help

Try this code:
class CustomSegue: UIStoryboardSegue {
override func perform() {
let firstVCView: UIView = self.source.view
let secondVCView: UIView = self.destination.view
self.destination.modalPresentationStyle = .fullScreen
let screenWidth = UIScreen.main.bounds.size.width
let screenHeight = UIScreen.main.bounds.size.height
secondVCView.frame = CGRect(x: screenWidth, y: 0, width: screenWidth, height: screenHeight)
let window = UIApplication.shared.keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
UIView.animate(withDuration: 0.4, animations: { () -> Void in
firstVCView.frame = firstVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
secondVCView.frame = secondVCView.frame.offsetBy(dx: -screenWidth, dy: 0.0)
}) { (Finished) -> Void in
self.source.present(self.destination as UIViewController,
animated: false,
completion: nil)
}
}
}
class CustomSegueUnwind: UIStoryboardSegue {
override func perform() {
let secondVCView: UIView = self.source.view
let firstVCView: UIView = self.destination.view
self.destination.modalPresentationStyle = .fullScreen
let screenWidth = UIScreen.main.bounds.size.width
let window = UIApplication.shared.keyWindow
window?.insertSubview(firstVCView, aboveSubview: secondVCView)
UIView.animate(withDuration: 0.4, animations: { () -> Void in
firstVCView.frame = firstVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
secondVCView.frame = secondVCView.frame.offsetBy(dx: screenWidth, dy: 0.0)
}) { (Finished) -> Void in
self.source.dismiss(animated: false, completion: nil)
}
}
}
