// (See usage below implementation)

// SwiftUI `CollectionView` type implemented with UIKit's UICollectionView under the hood.
// Requires `UIViewControllerRepresentable` over `UIViewRepresentable` as the type that allows
// for SwiftUI `View`s to be added as subviews of UIKit `UIView`s at all bridges this gap as
// the `UIHostingController`.
//
// Not battle-tested yet, but seems to be working well so far.
// Expect changes.
