Description

Routing is a lightweight SwiftUI navigation library.

• Leverages 1st-party APIs NavigationStack & NavigationDestination.
• Never be confused about NavigationLink or NavigationPath again! (You don't need them)
• Type-Safe Navigation (better performance than type-erasing).
• Centralized Navigation Logic.
• Dynamic Navigation Stack Management.
• Unit Tested protocol implementations.
• Zero 3rd party dependencies.
• Documentation

Note - This library is for NavigationStack only.
If you need to abstract sheets, alerts, etc. then use my other library Presenting

Installation

You can install Routing using the Swift Package Manager.

1. In Xcode, select File > Add Package Dependencies.

2. Copy & paste the following into the Search or Enter Package URL search bar.

https://github.com/JamesSedlacek/Routing.git

3. Xcode will fetch the repository & the Routing library will be added to your project.

Getting Started

1. Create a Route enum that conforms to the Routable protocol.

import Routing
import SwiftUI

enum ExampleRoute: Routable {
    case detail
    case settings
    
    var body: some View {
        switch self {
        case .detail:
            DetailView()
        case .settings:
            SettingsView()
        }
    }
}

2. Create a Router object and wrap your RootView with a RoutingView.

import SwiftUI
import Routing

struct ContentView: View {
    @StateObject private var router: Router<ExampleRoute> = .init()

    var body: some View {
        RoutingView(stack: $router.stack) {
            Button("Go to Settings") {
                router.navigate(to: .settings)
            }
        }
    }
}

3. Handle navigation using the Router functions

/// Navigate back in the stack by a specified count.
func navigateBack(_ count: Int)

/// Navigate back to a specific destination in the stack.
func navigateBack(to destination: Destination)

/// Navigate to the root of the stack by emptying it.
func navigateToRoot()

/// Navigate to a specific destination by appending it to the stack.
func navigate(to destination: Destination)

/// Navigate to multiple destinations by appending them to the stack.
func navigate(to destinations: [Destination])

/// Replace the current stack with new destinations.
func replace(with destinations: [Destination])

Passing Data Example

import Routing
import SwiftUI

enum ContentRoute: Routable {
    case detail(Color)
    case settings

    var body: some View {
        switch self {
        case .detail(let color):
            ColorDetail(color: color)
        case .settings:
            SettingsView()
        }
    }
}

struct ContentView: View {
    @StateObject private var router: Router<ContentRoute> = .init()
    private let colors: [Color] = [.red, .green, .blue]

    var body: some View {
        RoutingView(stack: $router.stack) {
            List(colors, id: \.self) { color in
                color
                    .onTapGesture {
                        router.navigate(to: .detail(color))
                    }
            }
        }
    }
}

struct ColorDetail: View {
    private let color: Color

    init(color: Color) {
        self.color = color
    }

    var body: some View {
        color.frame(maxWidth: .infinity, maxHeight: .infinity)
    }
}

Under the hood

The RoutingView essentially is just wrapping your view with a NavigationStack & navigationDestination.

NavigationStack(path: $routes) {
    root()
        .navigationDestination(for: Routes.self) { view in
            view.body
        }
}
