any chance you this LNZSnapToCenterCollectionViewLayout could support vertical alignments?

"This collection view layout is an horizontal layout that will allow pagination for items smaller than collection." I'm looking to achieve the same effect as facebook theatre mode / where you can watch tonnes of movies.

Controls Cell size

Hey there,
I don't know why but I can't change the cell sizes whenever I use any layout.

LNZInfiniteCollectionViewLayout crash

Library is crashing the app on layout update: https://www.fabric.io/s5a/ios/apps/com.saksfifthavenue.iphone/issues/599e7c19be077a4dcc8870e7?time=last-seven-days

My guess is that this problem happens when for some reason itemCount is set to 0 when prepare() is called, so that cycleSize.width is set to 0. Or itemSize.width + interitemSpacing is 0.
let width = (itemSize.width + interitemSpacing) * CGFloat(itemCount ?? 0)
Later on when override internal func items(in rect: CGRect) -> [(index:IndexPath, frame: CGRect)] is called and itemCount is greater than 0, which is checked at the start of the method, cycleSize.width remains set to 0 and crash happens let iFirstCycle = Int(floor((rect.origin.x - cycleStart) / cycleSize.width)).

Fix is in the following PR:
#2

Unable to compile in Xcode 10

The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions

The nil coalescing operators need to be broken up into their own variables.

LNZCollectionLayouts/LNZCollectionLayouts/Layouts/LNZSnapToCenterCollectionViewLayout.swift

Line 148 in 1ebff88

let h: CGFloat = (headerHeight ?? 0.0) + sectionInsetTop + sectionInsetBottom + itemSize.height + (footerHeight ?? 0.0)

Swift 5 Support

Are there any plans to support swift5?
I am very happy if you have the plan.

thanks.

How to change the cell size in collection view

Tagging a new minor release to support Carthage

Now that #28 has been merged (thanks for merging by the way 🙏🏻) I wanted to raise an issue to tag a minor point release just so that there's a release including this change.

When you add an entry e.g.

github gringoireDM/LNZCollectionLayouts

to a Cartfile, Carthage pulls the latest tag for the repo and builds using the shared scheme in the project. This means there needs to be a tagged release including the shared scheme.

If it would be possible to tag a minor release including this change that would be fantastic - thanks in advance.

'final3dTransform' is inaccessible due to 'private' protection level

When I integrated your library at my project I faced with this Error

xxx/LNZSafariTabLayout.swift:387:25: 'final3dTransform' is inaccessible due to 'private' protection level

I think, this problem cause by (private)
private func final3dTransform(forItemOrigin attributesOrigin: CGPoint, andSize attributesSize: CGSize, enforcingAngle angle: CGFloat? = nil) -> CATransform3D

May be it has to be fileprivate?

(because, You use function final3dTransform at extension(at the and of file))

How center to left scale, and make item between equals space?

private func configureAttributes(for attributes: UICollectionViewLayoutAttributes) {
    guard let collection = collectionView else { return }
    var visibleRect = CGRect()
    visibleRect.origin = collection.contentOffset
    visibleRect.size = collection.bounds.size
    let collectionLeft =  itemSize.width / 2
    let offset = collection.contentOffset.x
    let normalizedLeft =  attributes.center.x  - offset

    let maxDistance =  self.itemSize.width
    let distance = min(abs(collectionLeft - normalizedLeft), maxDistance)
    let ratio = (maxDistance - distance)/maxDistance
    let scale = ratio * (1 - sideItemScale) + sideItemScale

    var t = CATransform3DIdentity
    t = CATransform3DScale(t,  scale, scale, 1.0)
    attributes.zIndex = Int(scale * 10)
    attributes.transform3D = t
    //  change item space,
