Here is a high-level overview of each step

View: Displays the table view with the segregated dates, and communicates user interactions to the Presenter.

Interactor: Handles business logic, such as fetching the dates and segregating them into 30-minute intervals.

Presenter: Processes events from the View and the Interactor, preparing the data for display, and updating the View.

Entity: Represents the Date object used throughout the application.

Router: Manages navigation between screens.

SampleCode

import Foundation

protocol ChannelListPresenterProtocol: AnyObject { func viewDidLoad() }

protocol ChannelListInteractorProtocol: AnyObject { func fetchDates(completion: @escaping (Result<[Date], Error>) -> Void) }

class ChannelListListPresenter: ChannelListPresenterProtocol { weak var view: ChannelListViewProtocol? var interactor: ChannelListInteractorProtocol var router: ChannelListRouterProtocol

init(view: ChannelListViewProtocol, interactor: ChannelListInteractorProtocol, router: ChannelListRouterProtocol) {
    self.view = view
    self.interactor = interactor
    self.router = router
}

func viewDidLoad() {
    interactor.fetchDates { [weak self] result in
        switch result {
        case .success(let dates):
            let segregatedDates = segregateDatesByThirtyMinuteIntervals(dates: dates)
            DispatchQueue.main.async {
                self?.view?.displayDates(segregatedDates)
            }
        case .failure(let error):
            DispatchQueue.main.async {
                self?.view?.displayError(error.localizedDescription)
            }
        }
    }
}

}

class ChannelListInteractor: ChannelListInteractorProtocol { func fetchDates(completion: @escaping (Result<[Date], Error>) -> Void) { // Call the API to fetch the dates and return the result via the completion handler. } }
