# Deep links and navigation
|
||
|
||
## Intent
|
||
|
||
Route external URLs into in-app destinations while falling back to system handling when needed.
|
||
|
||
## Core patterns
|
||
|
||
- Centralize URL handling in the router (`handle(url:)`, `handleDeepLink(url:)`).
|
||
- Inject an `OpenURLAction` handler that delegates to the router.
|
||
- Use `.onOpenURL` for app scheme links and convert them to web URLs if needed.
|
||
- Let the router decide whether to navigate or open externally.
|
||
|
||
## Example: router entry points
|
||
|
||
```swift
|
||
@MainActor
|
||
final class RouterPath {
|
||
var path: [Route] = []
|
||
var urlHandler: ((URL) -> OpenURLAction.Result)?
|
||
|
||
func handle(url: URL) -> OpenURLAction.Result {
|
||
if isInternal(url) {
|
||
navigate(to: .status(id: url.lastPathComponent))
|
||
return .handled
|
||
}
|
||
return urlHandler?(url) ?? .systemAction
|
||
}
|
||
|
||
func handleDeepLink(url: URL) -> OpenURLAction.Result {
|
||
// Resolve federated URLs, then navigate.
|
||
navigate(to: .status(id: url.lastPathComponent))
|
||
return .handled
|
||
}
|
||
}
|
||
```
|
||
|
||
## Example: attach to a root view
|
||
|
||
```swift
|
||
extension View {
|
||
func withLinkRouter(_ router: RouterPath) -> some View {
|
||
self
|
||
.environment(
|
||
\.openURL,
|
||
OpenURLAction { url in
|
||
router.handle(url: url)
|
||
}
|
||
)
|
||
.onOpenURL { url in
|
||
router.handleDeepLink(url: url)
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
## Design choices to keep
|
||
|
||
- Keep URL parsing and decision logic inside the router.
|
||
- Avoid handling deep links in multiple places; one entry point is enough.
|
||
- Always provide a fallback to `OpenURLAction` or `UIApplication.shared.open`.
|
||
|
||
## Pitfalls
|
||
|
||
- Don’t assume the URL is internal; validate first.
|
||
- Avoid blocking UI while resolving remote links; use `Task`.
