How to copy design from destination in UIStoryboardSegue animation?

Question

Lets say I have two UIViewControllers, we can call them ControllerOne and ControllerTwo.

In my app I have created a custom UIStoryboardSegue animation between ControllerOne and ControllerTwo. The effect I want to create with the animation is that it will feel like a part from ControllerTwo sliding onto ControllerOne so that the segue between the two UIViewControllers does not seems to be a segue.

From this point I don´t know which approach is the best one to take. The design for ControllerTwo is set through the storyboard but how do I get it?

(What I know is that I can´t copy the values from ControllerTwo into the segue because they have not been set yet so it will throw an error.)

What values from ControllerTwo do you need to "copy into the segue"? — DonMag, Aug 26 '17 at 16:33

Usually we Passing Data via this func prepareForSegue in the UIViewController class

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "idFirstSegue" {
        let secondViewController = segue.destinationViewController as SecondViewController
        //secondViewController.message = ...
    }
}

You can also override perform func in the subclass of the UIStoryboardSegue class, here is the code :

 override func perform() {
  var firstVC = self.sourceViewController as UIViewController!
  var secondVC = self.destinationViewController as UIViewController!
 //Then copy design from destination  
}

The article fits you , I think.
