FetchingView

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Fetching view has a state machine called Fetching State :

enum FetchingState<A> {
    case fetching
    case fetchedError(AppErrorProvider)
    case fetchedData(A)
}

Fetching view will display UIActivityIndicatorView for FetchingState<A>.fetching and error message for .fetchedError(Error) state.
