Crash

Could not cast value of type 'UICollectionViewTransitionLayout' (0x10b5dbb08) to 'DisplaySwitcher.TransitionLayout' (0x1087e88f8).

In this function

open func startInteractiveTransition() {
UIApplication.shared.beginIgnoringInteractionEvents()
transitionLayout = collectionView.startInteractiveTransition(to: destinationLayout) { success, finish in
if success && finish {
self.collectionView.reloadData()
UIApplication.shared.endIgnoringInteractionEvents()
}
} as! TransitionLayout
transitionLayout.layoutState = layoutState
createUpdaterAndStart()
}

update this method:

func collectionView(_ collectionView: UICollectionView, transitionLayoutForOldLayout fromLayout: UICollectionViewLayout, newLayout toLayout: UICollectionViewLayout) -> UICollectionViewTransitionLayout {
let customTransitionLayout = TransitionLayout(currentLayout: fromLayout, nextLayout: toLayout)
return customTransitionLayout
}

it worked for me.

I tried this but, it didn't work.
