A library of Coordinator Patterns that are easy to use for dependency injections in applications written on pure Swift for iOS. Coordinator pattern This is an easy way to inject a presenter (UINavigationController) into each Navigator, rather than a complex child structure like other open sources.

FlowInject is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'FlowInject'

To use Navigator from the launch of the app, make sure to create the app’s window programmatically in AppDelegate.swift Then, set the Navigator as the root of the window’s view hierarchy in the AppDelegate.didFinishLaunching.

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
 var window: UIWindow?
 func application(_ application: UIApplication,
 didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
 
 self.window = UIWindow(frame: UIScreen.main.bounds)
 let appNavigator = AppNavigator(in: self.window)
 return true
 }
}

First, create an enum of the Route type. The cases of this Enum are used as paths. Then, the Navigator is inherited from the Navigator class and the Route type is designated as the generic type. After inheriting Navigator, inject the received presenter into initializer, Using navigate(to destination:), insert the service and the presenter to enable scene movement. In the case of screen movement, it did not implement logic such as transition (push, present, pop, disiss) because each developer has different custom needs. :]

I'll leave it up to you.

enum MainRoute: Route {
 case detail(content: String)
}
class MainNavigator: Navigator<MainRoute> {
 
 override init(with presenter: UINavigationController?) {
 super.init()
 self.presenter = presenter
 }
 
 func navigate(to destination: MainRoute) {
 switch destination {
 case .detail(let content):
 let viewController = DetailViewController(contentText: content,
 detailNavigator:DetailNavigator(with: presenter))
 presenter?.pushViewController(viewController, animated: true)
 }
 }
 
}
