XRouter

Basic Usage

Configure

Define Routes

enum AppRoute: RouteType {
    case newsfeed
    case login
    case signup
    case profile(userID: Int)
}

Create Router

class Router: XRouter<AppRoute> {

    override func prepareDestination(for route: AppRoute) throws -> UIViewController {
        switch route {
        case .newsfeed: return newsfeedController.rootViewController
        case .login: return LoginFlowCoordinator().start()
        case .signup: return SignupFlowCoordinator().start()
        case .profile(let userID): return UserProfileViewController(withID: userID)
        }
    }
    
}

Use Router

// Navigate directly to a route
router.navigate(to: .profile(3355))

// Open a URL
router.openURL(url)

Advanced Usage

RxSwift

XRouter also supports the RxSwift framework 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>

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 AppRoute: 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 AppRoute: RouteType {

    static func registerURLs() -> URLMatcherGroup<AppRoute>? {
        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 }
            }
        ])
    }

}

Handling errors

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:

  /// Hero cross fade transition
  let heroCrossFade = RouteTransition { (source, dest, animated, completion) in
      source.hero.isEnabled = true
      dest.hero.isEnabled = true
      dest.hero.modalAnimationType = .fade

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

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

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

        return .automatic
    }
