Dynamic Links Firebase on App Install SwiftUI - swift

Question

I can't get firebase dynamic links to work on new app installs for a SwiftUI app. Their documentation on step 6 and 7 shows stuff for AppDelegate https://firebase.google.com/docs/dynamic-links/ios/receive?authuser=0

I moved it to scene delegate but then it asked me to a add application open url so I did and ended up with this code:
extension AppDelegate {
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
let sceneConfig = UISceneConfiguration(name: nil, sessionRole: connectingSceneSession.role)
sceneConfig.delegateClass = SceneDelegate.self // 👈🏻
return sceneConfig
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
print("deeep shit")
return application(app, open: url,sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,annotation: "")
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
print("deeep shit 2")
if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
// Handle the deep link. For example, show the deep-linked content or
// apply a promotional offer to the user's account.
// ...
return true
}
return false
}
}
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use a UIHostingController as window root view controller.
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: RootView())
self.window = window
window.makeKeyAndVisible()
}
guard let userActivity = connectionOptions.userActivities.first(where: { $0.webpageURL != nil }) else { return }
print(userActivity)
}
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
print(URLContexts, "URLContexts")
}
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
print(userActivity.webpageURL, userActivity.referrerURL, "sdhagvdgjks")
}
}
RootView()
.onOpenURL(perform: { url in
DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicL, error in
if let url = dynamicL?.url {
/// do stuff
}
}
})

I skipped Scene Delegate and used the SwiftUI Modfier onContinuesUserActivity https://developer.apple.com/documentation/swiftui/view/oncontinueuseractivity(_:perform:)
extension AppDelegate {
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
return application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: "")
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
// Handle the deep link. For example, show the deep-linked content or
return true
}
return false
}
}
RootView()
.onOpenURL(perform: { url in
DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicL, error in
if let url = dynamicL?.url {
/// do stuff
}
}
})
.onContinueUserActivity(NSUserActivityTypeBrowsingWeb, perform: { activity in
print(activity.webpageURL, activity.referrerURL, "please work")
})
But then I get this error:
[Firebase/Analytics][I-ACS023001] Deep Link does not contain valid required params. URL params: {
"match_message" = "No pre-install link matched for this device.";
"request_ip_version" = "IP_V6";
}
Could someone please help me out?

Had the same problem as I was trying to implement referrals in my app Whisper Memos. Here's what worked for me:
Go to settings for your target, tab Info.
Find section URL Types
Add URL type with your bundle identifier. Should look something like this:
Your onOpenURL handler will now be called, but with a long URL, such as: tech.median.Whisper://google/link/?deep_link_id=https...
Convert your long URL to DynamicLink instance:
let dynamicLinks = DynamicLinks.dynamicLinks()
if let fromCustom = dynamicLinks.dynamicLink(fromCustomSchemeURL: url) {
deepLinkState.handleLink(link: fromCustom)
return
}
Now you can use this dynamic link to navigate inside your app.
