Analysis of problems in the implementation of AppCoordinator

This example shows a coordinator class responsible for displaying the profile screen and handling the user logout event. Note the use of RxSwift, DisposeBag, and capturing navigationController in the closure.

final class AppCoordinator {
    let navigationController: UINavigationController
    let disposeBag = DisposeBag()

    func presentProfile() {
        let controller = ProfileController()

        controller.rx.didTapLogout
            .bind(onNext: { [weak navigationController] in
                navigationController?.popToRootViewController(animated: true)
            })
            .disposed(by: disposeBag)

        navigationController.present(controller, animated: true)
    }
}
