PresentableInteractable

An Interactable that owns a presenter.

protocol PresentableInteractable : Interactable

Mentioned In

Overview

PresentableInteractable adds a single nonisolated presenter requirement to Interactable. The presenter is typically a @MainActor-isolated type, so calls into it from the interactor’s actor cross isolation domains and must be await-ed.

Overview

Use PresentableInteractable for any napkin that has a view; for view-less (“headless”) napkins, conform directly to Interactable. Pair this with a feature-specific Presentable protocol that the presenter conforms to:

protocol HomePresentable: Presentable {
    func presentUser(_ user: User) async
}

Usage

final actor HomeInteractor: PresentableInteractable {

    nonisolated let lifecycle = InteractorLifecycle()
    nonisolated let presenter: HomePresentable
    weak var listener: HomeListener?

    init(presenter: HomePresentable) {
        self.presenter = presenter
    }

    func didBecomeActive() async {
        await presenter.presentUser(.placeholder)
    }
}
