DeckTransition is an attempt to recreate the card-like transition found in the iOS 10 Apple Music and iMessage apps.
Hereʼs a GIF showing it in action.

- iOS 9 or later
To install DeckTransition using CocoaPods, add the following line to your Podfile:
pod 'DeckTransition', '~> 2.0'
To install DeckTransition using Carthage, add the following line to your Cartfile:

The transition can be called from code or using a storyboard.
To use via storyboards, just setup a custom segue (

Hereʼs a snippet showing usage via code. Just replace
ModalViewController() with your view controller's class and youʼre good to go.
let modal = ModalViewController() let transitionDelegate = DeckTransitioningDelegate() modal.transitioningDelegate = transitionDelegate modal.modalPresentationStyle = .custom present(modal, animated: true, completion: nil)
By default, DeckTransition has a swipe-to-dismiss gesture which is automatically enabled when your modalʼs main
UIScrollView is scrolled to the top.
You can opt-out of this behaviour by passing in
false for the
isSwipeToDismissEnabled parameter while initialising your
DeckTransition has an internal heuristic to determine which
UIScrollView should be tracked for the swipe-to-dismiss gesture. In general, this should be sufficient for and cover most use cases.
However there are some edge cases, and should you run into one, these can we worked around by making your modal view controller conform to the
DeckTransitionViewControllerProtocol protocol. More information about this can be found in the documentation page about UIScrollView detection.
For a variety of reasons, and especially because of iOS 11's safe area layout, DeckTransition uses a snapshot of your presenting view controller's view instead of using the view directly. This view is automatically updated whenever the frame is resized.
However, there can be some cases where you might want to update the snapshot view by yourself, and this can be achieved using the following one line snippet:
(presentationController as? DeckSnapshotUpdater)?.requestPresentedViewSnapshotUpdate()
All this does is request the presentation controller to update the snapshot.
You can also choose to update snapshot directly from the presenting view controller, as follows:
(presentedViewController?.presentationController as? DeckSnapshotUpdater)?.requestPresentedViewSnapshotUpdate()
It's worth noting that updating the snapshot is an expensive process and should only be used if necessary, for example if you are updating your entire app's theme.
