UIStoryboardSegue sourceViewController above destinationViewController - ios

Question

I want to "slide out" my view controller above the destinationViewController with a segue. This is my code:
override func perform()
{
let src = self.sourceViewController
let dst = self.destinationViewController
dst.view.superview?.insertSubview(src.view, aboveSubview: dst.view)
src.view.transform = CGAffineTransformMakeTranslation(0, 0)
UIView.animateWithDuration(0.25,
delay: 0.0,
options: UIViewAnimationOptions.CurveEaseInOut,
animations: {
src.view.transform = CGAffineTransformMakeTranslation(src.view.frame.size.width * -1, 0)
},
completion: { finished in
src.presentViewController(dst, animated: false, completion: nil)
}
)
}
The slide looks good, however the destinationViewController is all black during the animation, when the animation is completed the destinationViewController is shown correctly.
How can I make it display during segue animation?
EDIT:
solved it:
override func perform()
{
let src = self.sourceViewController
let dst = self.destinationViewController
src.view.superview?.insertSubview(dst.view, belowSubview: src.view)
dst.view.transform = CGAffineTransformMakeTranslation(0, 0)
UIView.animateWithDuration(0.25,
delay: 0.0,
options: UIViewAnimationOptions.CurveEaseInOut,
animations: {
src.view.transform = CGAffineTransformMakeTranslation(src.view.frame.size.width * -1, 0)
},
completion: { finished in
src.presentViewController(dst, animated: false, completion: nil)
}
)
}

Answer 1

Try this:
class FirstCustomSegue: UIStoryboardSegue {
override func perform() {
// Assign the source and destination views to local variables.
var firstVCView = self.sourceViewController.view as UIView!
var secondVCView = self.destinationViewController.view as UIView!
// Get the screen width and height.
let screenWidth = UIScreen.mainScreen().bounds.size.width
let screenHeight = UIScreen.mainScreen().bounds.size.height
// Specify the initial position of the destination view.
secondVCView.frame = CGRectMake(screenWidth, 0.0, screenWidth, screenHeight)
// Access the app's key window and insert the destination view above the current (source) one.
let window = UIApplication.sharedApplication().keyWindow
window?.insertSubview(secondVCView, aboveSubview: firstVCView)
// Animate the transition.
UIView.animateWithDuration(0.4, animations: { () -> Void in
firstVCView.frame = CGRectOffset(firstVCView.frame, -screenWidth, -0.0)
secondVCView.frame = CGRectOffset(secondVCView.frame, -screenWidth, -0.0)
}) { (Finished) -> Void in
self.sourceViewController.presentViewController(self.destinationViewController as! UIViewController,
animated: false,
completion: nil)
}
}
}

Try to add a Storyboard ID to your ViewController.
