Add Loading state to UIViewController

[piercifani]

The loading state and the error state of ListState are also used on ViewControllers without a collectionView and it would be useful to add an abstraction that fixes both cases

[deceroainfinito]

Do you mean something like...

protocol HasState: class {
    associatedtype T
    var state: ListState<T> { get set }
}

to apply as:

class CollectionViewStatefulDataSource<Cell: ViewModelReusable & UICollectionViewCell>: NSObject, UICollectionViewDataSource, HasState {
...
}

and also

class GIFCreateViewController: UIViewController, UITableViewDataSource, HasState {
...
}

Interesting: couple of questions:

• How would GIFCreateViewController or GIFDetailViewController conform to this?
• What kind of affordances we can bring to UIViewController/UIView to help development of apps using the HasState protocol?

And if we bring this protocol to UIViewController/UIView, maybe we need to rename ListState to just State, right?

Sure. Just "State" would fit better in most scenarios...
