// We have to import Reusable

import Reusable

// And add to it the StoryboardBased protocol
class ViewController2: UIViewController, StoryboardBased {

import SweetBubblesTransition

// Change your VC1's type by AnimationController
class ViewController: AnimationController {
    // You have to instantiate your VC2 by using the method .instantiate() (thanks again to Reusable).
    private let viewController2 = ViewController2.instantiate()

    // Now for this exemple I just create a button on the VC1, and assign it the following function
    @IBAction func change(_ sender: Any) {
        // ------------------------------- PARAMETERS INDICATIONS -------------------------------
        // 1. 'to' means the VC you want to transition to 
        // 2. 'animation' is the time of the transition. If you choose 2, for exemple, that means the VC2 will appear in two seconds.
        // 3. 'bubbleController' is the time you want to remove the BubbleViewController
        // Personnally I think 3sec for the animation and 2.5sec to delete the BubbleVC is the perfect timing, but feel free to make your own opinion !
        startTransition(to: viewController2, animation: 3, bubbleController: 2.5)
