README.md

usage

class AppDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        let tabC = UITabBarController()
        let mC = MCoordinator()
        
        coordinator = MainCoordinator(tabBarController: tabC, tabs: [mC])
        coordinator?.start()
        window?.rootViewController = tabC
        return true
    }
}

protocol.swift

import UIKit.UITabBarController
import UIKit.UINavigationController
import UIKit.UIViewController
import UIKit.UITabBarItem

protocol Coordinator {
    var childCoordinators: [Coordinator] { get set }
    func start()
    var rootViewController:UIViewController {get}
}
protocol NavigationCoordinator:Coordinator {
    var navigationController: UINavigationController? { get set }
}

protocol TabBarCoordinator:Coordinator {
    var tabBarController:UITabBarController? {get set}
    var tabBarItem:UITabBarItem? {get}
