        let selector = #selector(UIViewController.viewDidLoad)
        return publisher(for: selector)
            .map { _ in () }
            .eraseToAnyPublisher()
    }
    
    var viewWillAppearPublisher: AnyPublisher<Bool, Never> {
        let selector = #selector(UIViewController.viewWillAppear(_:))
        return intercept(selector)
            .map { $0[0] as? Bool ?? false }
            .eraseToAnyPublisher()
    }
}

class ViewController: UIViewController {
    private var subscriptions = Set<AnyCancellable>()
    
    private func bind() {
        viewDidLoadPublisher
            .sink(receiveValue: { _ in
                print("viewDidLoad")
            })
            .store(in: &subscriptions)
        
        viewWillAppearPublisher
            .sink(receiveValue: { isAnimated in
                print("viewWillAppearPublisher", isAnimated)
