Make your modal transition with custom animation. AZTransitions helps you think about creativity, giving specific API methods.

Visual Example

Inside this repository you can try iOS Example target with example FashionTransition.swift class:

[Animation example](imgs/animation_example.gif)


  • Add the following to your Podfile and run pod install ruby pod 'AZTransitions'
  • or add the following to your Cartfile and run carthage update github "azimin/AZTransitions"
  • or clone as a git submodule,

  • or just copy AZTransitions/Source/CustomModalTransition.swift into your project.

Code Example

To create any custom transition just subclass CustomModalTransition:

class FashionTransition: CustomModalTransition { 
  override init() {
    super.init(duration: 0.5)


Then set as az_modalTransition to nessesary view just before presenting it

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  segue.destination.customModalTransition = FashionTransition()


func show() {
  let viewController = UIViewController()
  viewController.customModalTransition = FashionTransition()
  self.present(viewController, animated: true, completion: nil)


To have custom present animation, just implement performTransition(interactive: Bool) inside your FashionTransition class:

func performTransition(interactive: Bool) {
  self.presentedViewController.view.alpha = 0.0

  UIView.animate(withDuration: duration, animations: {
    self.presentedViewController.view.alpha = 1.0
    self.presentingViewController.view.alpha = 0.0
  }, completion: { (completed) in
    self.presentingViewController.view.alpha = 1.0
    self.finishAnimation(completion: nil)

As you may have guessed, you have different properties. The main ones:

  • duration — transition duration
  • presentingViewController — the presenting view controller (bottom one)
  • presentedViewController — view controller that is going to be presented (top one)

You can animate them as you want.

🔥IMPORTANT🔥 don't forget to call finishAnimation(completion: nil) in the end.

In this case animation will be:

Of course sometimes you want to use diffenret modal presentation styles (for example overCurrentContext), in this case you can call setCustomModalTransition(customModalTransition: CustomModalTransition, inPresentationStyle: UIModalPresentationStyle) of UIViewController instead of setting customModalTransition directly.


You have different properties and methods to help you:

  • performDismissingTransition(interactive: Bool) to implement custom transition animation when dismissing
  • fromViewController/toViewController in term of Apple transition. They are reversed in presenting and dismissing transitions.
  • transitionContainerView view where the transition takes place (resentingViewController.view and presentedViewController.view located on inside transitionContainerView), so you can add your custom views here to make animation more interesting (see iOS Example)
  • Some methods for interactive animations (example will be added be soon)
  • Some method to work with orientation changing things (example will be added be soon)
