Answer 1

// call following code in the method where you want to add animation effect.
func buttonClicked(sender: UIButton){
let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
self.navigationController?.view.layer.addAnimation(transition, forKey: nil)
self.navigationController?.pushViewController(vc!, animated: true)
}
// you can vary the duration of transition according to your convenience
// here transition.type are types of animation which you want to add on view. now we are pushing view so used push type. if want, you can google it for more types.
// subtype will decide the direction on animation.

Answer 2

You do not have to use prepareForSeque, you can do like this:
#IBAction func buttonClicked(sender: UIButton) {
let destinationVC = storyboard?.instantiateViewControllerWithIdentifier("viewcontrollerID") as! ViewControllerClass
self.presentViewController(destinationVC, animated: true, completion: nil)
}
viewcontrollerID is set in storyboard (it is called identity in attribute inspector (right panel)), it should be unique, ViewControllerClass is class of your ViewController
If you are using UINavigationController
#IBAction func buttonClicked(sender: UIButton) {
let destinationVC = storyboard?.instantiateViewControllerWithIdentifier("viewcontrollerID") as! ViewControllerClass
self.navigationController?.pushViewController(destinationVC, animated: true)
}
