Nice article and approach but need help

In the code looks like there is some diffing implementation started, but seems like not finished.

I'm trying to make it working with RxDataSources, so far only:

Protocol 'CellConfigurator' can only be used as a generic constraint because it has Self or associated type requirements when I'm trying to extend CellConfigurator with IdentifiableType. Maybe you can suggest another some nice hack that could solve this problem.

protocol CellConfigurator: CellSizable, Diffable, SelectableData, IdentifiableType  {
    static var cellType: GenericCell.Type { get }
    static var cellReuseIdentifier: String { get }
    
    func configure(cell: UIView)
    func didSelect()
}

protocol ConfigurableCell: GenericCell, Reusable {
    associatedtype DataType
    func configure(item: DataType)
}

//defines that object should return its configurator
protocol CellConfigurable {
    func configurator() -> CellConfigurator // <- Protocol 'CellConfigurator' can only be used as a generic constraint because it has Self or associated type requirements
}
