How to get an unownedRouter for RedirectionRouter?

[kevinrenskers]

This is the example in the project readme:

class ParentCoordinator: NavigationCoordinator<ParentRoute> {
    /* ... */
    
    override func prepareTransition(for route: ParentRoute) -> NavigationTransition {
        switch route {
        /* ... */
        case .child:
            let childCoordinator = ChildCoordinator(parent: unownedRouter)
            return .push(childCoordinator)
        }
    }
}

class ChildCoordinator: RedirectionRouter<ParentRoute, ChildRoute> {
    init(parent: UnownedRouter<ParentRoute>) {
        let viewController = UIViewController() 
        // this viewController is used when performing transitions with the Subcoordinator directly.
        super.init(viewController: viewController, parent: parent, map: nil)
    }
    
    /* ... */
    
    override func mapToParentRoute(for route: ChildRoute) -> ParentRoute {
        // you can map your ChildRoute enum to ParentRoute cases here that will get triggered on the parent router.
    }
}

But what do you do when viewController needs be passed an UnownedRouter<ChildRoute> so it can trigger routes? RedirectionRouter doesn't have an unownedRouter like actual coordinators do.

Hey @kevinrenskers,

UnownedRouter is actually a typealias for UnownedErased<StrongRouter>, so you should actually be able to do the following:

extension RedirectionRouter {
    var unownedRouter: UnownedRouter<RouteType> {
        UnownedRouter(self) { $0.strongRouter }
    }
}

Let me know, if this helps - it would probably be a nice addition for the framework as well!
