use_frameworks!
pod "Fun"

Manually

Copy Sources folder to your Xcode project.

Usage

How to use Fun to create a custom transition:

Code

In the root view controller or the first view controller:

Get a reference to your Navigation or TabBar Controller
Create a Navigation or TabBar Controller delegate using Navigation or TabBar Controller, transition type and is Interactive as parameters.
Optional: in your delegate object

set the transition duration
set the gesture direction

Your Done!

Navigation Controller

// In the root view  controller
override func viewDidLoad() {
super.viewDidLoad()
// 1-  Get a reference to your Navigation Controller
guard let navigationController = self.navigationController else {
return
}
// 2- Create a Navigation Controller delegate with :
let navigationControllerDelegate = FunNavigationControllerDelegate.init(navigationController: navigationController, transitionType: .ZoomBlur, isInteractive: true)
// 3- Optional: in your delegate object
//     - set the transition duration
//     - set the gesture direction
navigationControllerDelegate.duration = 1.4
navigationControllerDelegate.gesturePopDirection = .LeftToRight
}

TabBar Controller

// In the first view  controller
override func viewDidLoad() {
super.viewDidLoad()
// 1-  Get a reference to your TabBar Controller
guard let tabBarController = self.tabBarController else {
return
}
// 2- Create a tabBar Controller delegate with :
let tabBarControllerDelegate = FunTabBarControllerDelegate.init(tabBarController: tabBarController, transitionType: .ZoomBlur, isInteractive: true)
// 3- Optional: in your delegate object
//     - set the transition duration
//     - set the gesture direction
tabBarControllerDelegate.duration = 1.4
tabBarControllerDelegate.gestureDirection = .LeftToRight
}

In code

In the source or presenting view controller:

Create or get a reference to your destination controller
set the modal Presentation Style of your destination controller to full screen
Create a Modal Controller delegate using the destination controller and a transition type as parameters.
Optional:

make the transition interactive
set the transition duration
set the gesture direction

Your Done!

// In the source or presenting view  controller:
@IBAction func presentViewControllerModally(_ sender: Any) {
// 1- Create your destination Controller
guard let destinationController = storyboard?.instantiateViewController(withIdentifier: "desVC") as? DestinationViewController else { return }
/* 
or get a reference to your destination controller if you are using prepare for segue function
let destinationController = segue.destination
*/
// 2- set the modal Presentation Style of your destination controller to full screen
destinationController.modalPresentationStyle = .fullScreen
// 3- Create a Modal Controller delegate using the destination controller and a transition type as parameters.
let controllerDelegate = FunModalControllerDelegate.init(destinationController: destinationController, transitionType: .ZoomBlur)
// 4- Optional:
// - make the transition interactive
// supply a pan gesture if the destination controller view already has a one, if not do not warry about it, the Modal Controller Delegate will create one for you. 
controllerDelegate.addInteractiveToDestinationController(panGesture: nil)
// - set the transition duration
controllerDelegate.duration = 2
// - set the gesture direction
controllerDelegate.gestureDismissalDirection = .RightToLeft
// - present the destination controller modally
present(destinationController, animated: true, completion: nil)
