You could make an enum and extend the Route, NavLink and Navigator to accept this enum.

As an example:

enum AppRoute: String {
	case news
	case settings
	case login
}

extension Route where ValidatedData == RouteInformation {
	init(route: AppRoute, @ViewBuilder content: @escaping (ValidatedData) -> Content) {
		self.init(route.rawValue, content: content)
	}
}

extension Navigator {
	func navigate(_ route: AppRoute) {
		self.navigate(route.rawValue)
	}
}

extension NavLink {
	init(to route: AppRoute, replace: Bool = false, exact: Bool = false, @ViewBuilder content: @escaping (Bool) -> Content) {
		self.init(to: route.rawValue, replace: replace, exact: exact, content: content)
	}
}

navigator.navigate(to: .news)

You can now use type safe routes.

Things become a bit more complicated when you want to work with parameters/placeholders however. But with Swift's enum having support for associated values you could probably come up with some wicked things:

enum AppRoute {
	case news(id: UUID? = nil)
	case settings
	case login

	var path: String {
		switch self {
		case .news(let id): return "/news/\(id?.uuidString ?? "")"
		case .settings: return "/settings"
		case .login: return "/login"
		}
	}
}

navigator.navigate(to: .news(id: someUUID))

@frzi Makes sense, thank you!

@frzi I can't seem to figure out what the Route init would look like when using enum AppRoute with associated values on some of the cases. Am I right in suspecting that it's not simple?

You'll probably want the paths for Routes to be formed differently. As an example:

enum AppRoute {
	case news(id: UUID? = nil)

	// Read this property in `NavLink` and `Navigator.navigate()`
	var path: String {
		switch self {
		case .news(let id): return "/news/\(id?.uuidString ?? "")"
		}
	}

	// Read this property in `Route`
	var route: String {
		switch self {
		case .news(let id): return "/news/\(id?.uuidString ?? ":id?")"
		}
	}
}

Route(.news()) { /* ... */ } // For `/news/:id?`
Route(.news(someConstantUUID)) { /* ... */ } // For `/news/edc54f97-ff00-463a-8897-f75144e41b7b` or something

With a bit of imagination I'm sure you'll be able to come up with a solution that fits your needs perfectly. 😄
