enum YourEnum: Int, Enumerable {
  case one
  case two
  case three
  case four
}

print(YourEnum.count) // 4

It is particularly compatible with TableView and CollectionView.

enum RowType: Int, Enumerable {
  case one
  case two
  case three
  case four
}

public func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
  return RowType.count
}


public func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
  guard let item = RowType(rawValue: indexPath.item) else {
    fatalError("out of section type: \(indexPath.section), model has sections: \(String(describing: model?.sections))")
  }
  switch item {
    case .one:
    case two:
  ...
  }
  ...
}
