ForegroundViewStore

[MSWagner]

Per default, StatefulViewController presents the placeholder views above all other views. In case other views, like some buttons, should be above the placholder in some states, you can assign a dictionary [StatefulViewControllerState: Set<UIView>] to the foregroundViewStore property.

foregroundViewStore = [
    .empty: [button1, button2],
    .error: [button1]
]

You can also update the foregroundViewStore later:

foregroundViewStore?[.empty]?.remove(button1)
foregroundViewStore?[.loading]?.insert(button3)
