Framework that provide convenient environment for manage navigation in SwiftUI.


  • 🤢 No boolean flag such as @State var isActive
  • 🤮 No enum flag such as @State var route: RouteAction? with big switch-case statement
  • 🤡 No implicit UIKit hacks with UIViewController
  • 💩 No singleton/shared/global presenter of application

🔩 Requirements

  • iOS 14.0+
  • Xcode 12.0+
  • Swift 5.3+

🧐 How does it work?!

Framework has only two state object, each of which isolates "toggle-work" of @State var isActive: Bool and @State var isPresent: Bool flags.

1. NavigationStackController

Like UINavigationController, it store stack state and provide stack transformation using push and pop methods:

let navigationStackController = NavigationStackController()

// Standard usage

navigationStackController.push(Text("My View"))

// Advanced usage

enum Screen: Hashable { 
    case detail

navigationStackController.push(tag: Screen.detail, DetailView())
navigationStackController.pop(to: Screen.detail)

Its companion is NavigationStackView – wrapper over NavigationView that bind NavigationStackController with it:

struct ContentView: View { 
    @StateObject var navigationStackController = NavigationStackController() 

    var body: some View { 
        NavigationStackView(navigationStackController) { 
                showDetails: { model in 
                    navigationStackController.push(DetailView(model: model))
                showSettings: { 

// Another usage with automatic initialized NavigationStackController

struct ContentView: View { 
    var body: some View { 
        NavigationStackView { controller in
                showDetails: { model in 
                    controller.push(DetailView(model: model))
                showSettings: { 

Any pushed view has access to NavigationStackController of NavigationStackView through EnvironmentObject:

struct DetailView: View { 
    let model: Model
    @EnvironmentObject var navigationStackController: NavigationStackController

    var body: some View { 
        VStack { 
            Button("pop to root") { 

💫 EXTRA FEATURE: You can tag any pushed view using any Hashable type. It allow refer to specific screen on pop:

navigationStackController.push(tag: "Screen 1", Screen1()))
navigationStackController.pop(to: "Screen 1")

2. ModalStackController

Like NavigationStackController, the ModalStackController control modal stack hierarchy and provide stack transformation using present and dismiss methods:

let modalStackController = ModalStackController()

// Standard usage

modalStackController.present(.sheet, Text("My View"))
modalStackController.present(.fullScreenCover, Text("Another View"))

// Advanced usage

enum Screen: Hashable { 
    case detail

modalStackController.present(.sheet, tag: Screen.detail, DetailView())
modalStackController.dismiss(to: Screen.detail)

🚧 NOTE: SwiftUI does not allow to dismiss multiple views at once! Therefore, methods such as dismissAll() or dismiss(to:)/dismiss(from:) will close all views sequentially.

To attach ModalStackController to a view, you need to declare a root view on top of which all views will be presented using the method definesPresentationContext(with:):

struct ExampleApp: App { 
    @StateObject var modalStackController = ModalStackController()

    var body: some Scene { 
        WindowGroup { 
                .definesPresentationContext(with: modalStackController)
                // or just call .definesPresentationContext()

Any presented view has access to ModalStackController through EnvironmentObject too:

struct RootView: View { 
    @EnvironmentObject var modalStackController: ModalStackController

    var body: some View { 
        VStack { 
            Text("Home screen")
            Button("FAQ") { 
                modalStackController.present(.sheet, FAQView())
            Button("Authorize") { 
                modalStackController.present(.fullScreenCover, LoginView())

💫 Just like in NavigationStackController you can tag presented views when present with ModalStackController



  • push
  • push(tag:)
  • pop
  • pop(tag:)
  • popLast(_ k:)
  • popToRoot


  • present(_ presentationStyle:)
  • present(_ presentationStyle:tag:)
  • dismiss
  • dismiss(tag:)
  • dismissLast(_ k:)
  • dismissAll
  • PresentationStyle
    • sheet
    • fullScreenCover


Can i mix this framework with existing navigation approach in my project?

Yes, you can. The framework does not affect navigation built in other ways, such as through the standard @State var isActive: Bool flags or through UIKit hacks.
NavigationStackController and ModalStackController create local state and manage only their own state.

What about Alert?

Unfortunately, the framework does not support such a mechanism for working with Alert, BUT you can implement it yourself by analogy with ModalStackController.
Your project can have many different custom presentations (popup, snackbar, toast, notifications) and each of them require specific logic for handle hierarchy, depending on their implementation.
So adding new presentation methods to the framework is not planned.
