Swift 4.2 & 5.0. Ready for use on iOS 10+



CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate SPStorkController into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'SPStorkController'


Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate SPStorkController into your Xcode project using Carthage, specify it in your Cartfile:

github "IvanVorobei/SPStorkController"


If you prefer not to use any of the aforementioned dependency managers, you can integrate SPStorkController into your project manually. Put Source/SPStorkController folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

Quick Start

Create controller and call func presentAsStork:

import UIKit
import SPStorkController

class ViewController: UIViewController {

    override func viewDidAppear(_ animated: Bool) {

        let controller = UIViewController()

If you want customize controller (remove indicator, set custom height and other), create controller and set transitioningDelegate to SPStorkTransitioningDelegate object. Use present or dismiss functions:

let controller = UIViewController()
let transitionDelegate = SPStorkTransitioningDelegate()
controller.transitioningDelegate = transitionDelegate
controller.modalPresentationStyle = .custom
controller.modalPresentationCapturesStatusBarAppearance = true
self.present(controller, animated: true, completion: nil)

Please, do not init SPStorkTransitioningDelegate like this:

controller.transitioningDelegate = SPStorkTransitioningDelegate()

You will get an error about weak property.


Light StatusBar

To set light status bar for presented controller, use preferredStatusBarStyle property. Also set modalPresentationCapturesStatusBarAppearance. See example:

import UIKit

class ModalViewController: UIViewController {

    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent

Custom Height

Property customHeight sets custom height for controller. Default is nil:

transitionDelegate.customHeight = 350

Close Button

Property showCloseButton added circle button with dismiss action. Default is false:

transitionDelegate.showCloseButton = false


On the top of controller you can add arrow indicator with animatable states. It simple configure.
Property showIndicator shows or hides top arrow indicator. Default is true:

transitionDelegate.showIndicator = true

Property Parameter indicatorColor for customize color of arrow. Default is gray:

transitionDelegate.indicatorColor = UIColor.white

Property hideIndicatorWhenScroll shows or hides indicator when scrolling. Default is false:

transitionDelegate.hideIndicatorWhenScroll = true


You can also configure events that will dimiss the controller.
Property swipeToDismissEnabled enables dismissal by swipe gesture. Default is true:

transitionDelegate.swipeToDismissEnabled = true

Property translateForDismiss sets how much need to swipe down to close the controller. Work only if swipeToDismissEnabled is true. Default is 240:

transitionDelegate.translateForDismiss = 100

Property tapAroundToDismissEnabled enables dismissal by tapping parent controller. Default is true:

transitionDelegate.tapAroundToDismissEnabled = true

Corner Radius

Property cornerRadius for customize corner radius of controller’s view. Default is 10:

transitionDelegate.cornerRadius = 10


Property hapticMoments allow add taptic feedback for some moments. Default is .willDismissIfRelease:

transitionDelegate.hapticMoments = [.willPresent, .willDismiss]


The project uses a snapshot of the screen in order to avoid compatibility and customisation issues. Before controller presentation, a snapshot of the parent view is made, and size and position are changed for the snapshot. Sometimes you will need to update the screenshot of the parent view, for that use static func:

SPStorkController.updatePresentingController(modal: controller)

and pass the controller, which is modal and uses SPStorkTransitioningDelegate.

Add Navigation Bar

You may want to add a navigation bar to your modal controller. Since it became impossible to change or customize the native controller in swift 4 (I couldn’t even find a way to change the height of the bar), I had to recreate navigation bar from the ground up. Visually it looks real, but it doesn’t execute the necessary functions:

import UIKit
import SPFakeBar

class ModalController: UIViewController {

    let navBar = SPFakeBarView(style: .stork)

    override func viewDidLoad() {

        self.view.backgroundColor = UIColor.white

        self.navBar.titleLabel.text = "Title"
        self.navBar.leftButton.setTitle("Cancel", for: .normal)
        self.navBar.leftButton.addTarget(self, action: #selector(self.dismissAction), for: .touchUpInside)


You only need to add a navigation bar to the main view, it will automatically layout. Use style .stork in init of SPFakeBarView. Here is visual preview with Navigation Bar and without it:

To use it, you need to install SPFakeBar pod:

pod 'SPFakeBar'

Working with UIScrollView

If you use UIScrollView (or UITableView & UICollectionView) on controller, I recommend making it more interactive. When scrolling reaches the top position, the controller will interactively drag down, simulating a closing animation. Also available close controller by drag down on UIScrollView. To do this, set the delegate and in the function scrollViewDidScroll call:

func scrollViewDidScroll(_ scrollView: UIScrollView) {

Working with UITableView & UICollectionView

Working with a collections classes is not difficult. In the Example folder you can find an implementation. However, I will give a couple of tips for making the table look better.

Firstly, if you use SPFakeBarView, don’t forget to set top insets for content & scroll indicator. Also, I recommend setting bottom insets (it optional): = self.navBar.height = self.navBar.height

Please, also use SPStorkController.scrollViewDidScroll function in scroll delegate for more interactiveness with your collection or table view.


You can check events by implement SPStorkControllerDelegate and set delegate for transitionDelegate:

transitionDelegate.storkDelegate = self

Delagate has this functions:

protocol SPStorkControllerDelegate: class {

    optional func didDismissStorkBySwipe()

    optional func didDismissStorkByTap()

Modal presentation of other controller

If you want to present modal controller on SPStorkController, please set:

controller.modalPresentationStyle = .custom

It’s needed for correct presentation and dismissal of all modal controllers.

Stop scroll

SPStorkController use snapshots. If the parent controller scrollings and you try to show SPStorkController, you will see how it froze, and in a second its final position is updated. I recommend to stop scrolling force:

scrollView.setContentOffset(self.contentOffset, animated: false)
