sRouting

The lightweight navigation framework for SwiftUI.

Overview

sRouting using the native navigation mechanism in SwiftUI. It's easy to handle navigation between screens by sRouting. The Router can trigger a transition from inside(view) or outside(view model) the view.

Requirements

• iOS 14 or above
• Xcode 13 or above

🏃‍♂️ Getting Started with sRouting

Set up RootView and working with Router

Overview

Create your root view with RootView. Declares your Route. Working with ScreenView and Router.

Create a Route

To create a Route we have to conform the Route Protocol.

enum AppRoute: Route {
    case login
    case home

    var screen: some View {
        switch self {
            case .login: LoginScreen()
            case .home: HomeScreen()
        }
    }
}

Make your Root View

Setup the RootView for your app

@main
struct BookieApp: App { 
    ...
    @SceneBuilder
    var body: some Scene { 
        WindowGroup {
            RootView(rootRouter: .init()) {
                NavigationView {
                    AppRoute.home.screen
                }
                .navigationViewStyle(.stack)
            }
        }
    }
}

Make a Screen and working with Router

Build a screen with ScreenView, ScreenView will create a hidden NavigatorView at below content view in a ZStack. The NavigatorView will handle transactions that are emited by Router

struct HomeScreen: View {

    @Environment(\.presentationMode)
    private var presentationMode
    
    @StateObject
    private var router: Router = .init()

    var body: some View {
        ScreenView(router: router, presentationMode: presentationMode) {
        ...
        }
    }

To navigate to a screen that must be in AppRoute we use the Router/trigger(to:with:) function in the Router

Push:

router.trigger(to: .loginScreen, with: .push)

Present full screen:

router.trigger(to: .loginScreen, with: .present)

Sheet:

router.trigger(to: .loginScreen, with: .sheet)

To show an alert we use the Router/show(alert:) function.

 router.show(alert:  Alert.init(title: Text("Alert"),
                                message: Text("Message"),
                                dismissButton: .cancel(Text("OK")))

To show an error message we use the Router/show(error:and:) function.

router.show(error:NetworkingError.lossConnection)

To dismiss or pop screen we use the Router/dismiss() function.

router.dismiss()

To dismiss to root view we use the Router/dismissAll() function. Required the root view is a RootView

router.dismissAll()

To seclect the Tabbar item we use the Router/selectTabbar(at:) function. Required the TabView selection binding from RootRouter.

router.selectTabbar(at:0)

Using Router in a ViewModel

Also the router can be used in a ViewModel.

class HomeViewModel: Router {
...
}

struct HomeScreen: View {

    @Environment(\.presentationMode)
    private var presentationMode
    
    @StateObject
    private var viewModel: HomeViewModel = .init()

    var body: some View {
        ScreenView(router: viewModel, presentationMode: presentationMode) {
        ...
        }
    }

Now you can navigate to new screen in HomeViewModel, that's cool right?

Note

Make sure the transition is performed on MainThread.

Conclusion

sRouting is a lightweight framework and flexiable, so you can handle the navigations by whatever you want.
