Get started

Installation

Swift Package Manager (SPM)

XRouter is available via Swift Package Manager version 2.0.1 onwards.

CocoaPods

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

pod 'XRouter'

Basic Usage

Defining your routes

Create a file containing the routes for your application.

enum Route: RouteType {
    case login
    case profile(userID: Int)
}
Create a Router

Configure a concrete instance of XRouter to resolve a standalone view controller, or start a modal flow by passing a navigation controller.

class Router: XRouter<Route> {
    override func prepareDestination(for route: Route) throws -> UIViewController {
        switch route {
        case .login:
            return AuthLoginFlowCoordinator().navigationController

        case .profile(let userID):
            return UserProfileViewController(profile: try repo.fetch(user: userID))
        }
    }
}
Perform navigation
router.navigate(to: .profile(userID: 3355))

Advanced Usage

Deep Link Support

XRouter provides support for deep links and universal links.

You only need to do one thing to add URL support for your routes. Implement the static method registerURLs:

enum Route: RouteType {
    static func registerURLs() -> URLMatcherGroup<Route>? {
        return .group {
            $0.map("/products") { .allProducts }
            $0.map("/user/*/logout") { .logout }
            $0.map("/products/{cat}/view") { try .products(category: $0.path("cat")) }

            $0.map("/user/{id}/profile") {
                try .viewProfile(withID: $0.path("id"), parameters: $0.query)
            }
        }
    }
}

Then you can call the openURL(_:animated:completion:) and/or continue(_ userActivity:) methods, e.g. from in your AppDelegate:

extension AppDelegate {
    /// Handle deep links.
    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
        return router.openURL(url, animated: false)
    }

    /// Handle universal links.
    func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
        return router.continue(userActivity)
    }
}

You can even define more advanced URL routing. For example, these rules could be used to match:

  • http://example.com/login --> .login
  • https://example.com/signup --> .signup
  • customScheme://myApp/qr-code?code=abcdef... --> .openQRCode("abcdef...")
  • https://www.example.com/products --> .allProducts
  • https://api.example.com/user/my-user-name/logout --> .logout
enum Route: RouteType {
    static func registerURLs() -> URLMatcherGroup<Route>? {
        return .init(matchers: [
            .host("example.com") {
                $0.map("/login") { .login }
                $0.map("/signup") { .signup }
            },
            .scheme("customScheme") {
                $0.map("/qr-code") { .openQRCode($0.query("code")) }
            },
            .group {
                $0.map("/products") { .allProducts }
                $0.map("/user/*/logout") { .logout }
            }
        ])
    }
}

Global error navigation handling

If you handle all navigation errors in the same way, you can override the received(unhandledError:) method.

class Router: XRouter<Route> {
    override func received(unhandledError error: Error) {
        log.error("Oh no! An error occured: \(error)")
    }
}

Or you can set a custom completion handler for some individual navigation action:

router.navigate(to: .profilePage(withID: 24)) { (optionalError) in
    if let error = optionalError {
        print("Oh no, we couldn't go here because there was an error!")
    }
}

Custom Transitions

Here is an example using the popular Hero Transitions library.

Define your custom transitions:

  /// Perform a cross-fade transition using Hero library.
  static let heroCrossFade = RouteTransition { (source, destination, animated, completion) in
      source.hero.isEnabled = true
      destination.hero.isEnabled = true
      destination.hero.modalAnimationType = .fade

      /* Present the hero animation */
      source.present(destination, animated: animated) {
          completion(nil)
      }
  }

And set the transition to your custom transition in your Router:

    override func transition(for route: Route) -> RouteTransition {
        if case .profile = route {
          return .heroCrossFade
        }

        return .automatic
    }

RxSwift Support

XRouter also supports Rx out of the box. Bindings exist for navigate(to:), which returns a Completable, and openURL(_:), which returns a Single<Bool>.

router.rx.navigate(to: .loginFlow) // -> Completable
router.rx.openURL(url) // -> Single<Bool>

Demo Project

To run the example project, clone the repo, and run it in the latest version of Xcode.
