Install through Carthage:

github "andreamazz/BubbleTransition"

Swift 1.2

use_frameworks!

#Setup Have your viewcontroller conform to UIViewControllerTransitioningDelegate. Set the transitionMode, the startingPoint, the bubbleColor and the duration.

let transition = BubbleTransition()

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let controller = segue.destinationViewController
    controller.transitioningDelegate = self
    controller.modalPresentationStyle = .Custom
}

// MARK: UIViewControllerTransitioningDelegate

func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    transition.transitionMode = .Present
    transition.startingPoint = someButton.center
    transition.bubbleColor = someButton.backgroundColor!
    return transition
}

func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    transition.transitionMode = .Dismiss
    transition.startingPoint = someButton.center
    transition.bubbleColor = someButton.backgroundColor!
    return transition
}

You can find the Objective-C equivalent here.
