Reusable is a Swift µpackage that provides a type-safe way for cell registration and dequeuing in both table and collection views. It is based on [this post](https://gonzalezreal.github.io/2015/12/31/ios-cell-registration-reusing-with-swift-protocol-extensions-and-generics.html)

Usage

To be able to register and reuse a cell or supplementary view in a type-safe way, the view must conform to the ReusableView protocol:

extension PosterItemCell: ReusableView {}

The default implementation of ReusableView will provide a reuse identifier based on the class name.

Cells implemented with Interface Builder must also conform to the NibLoadableView protocol:

extension PosterItemCell: ReusableView, NibLoadableView {}

Once the cell or supplementary view is ready, you can register it in a collection or table view by indicating its type:

func viewDidLoad() {
  super.viewDidLoad()
  collectionView.register(PosterItemCell.self)
  ...
}

Likewise, you can dequeue a cell previously registered in this way just by indicating its type:

func collectionView(_: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(PosterItemCell.self, for: indexPath)
    ...
    return cell
}

Installation
