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 Route
s 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. 😄
