iOS/Swift: How to get dynamic deep links that survive the install from app store WITH parameters by configuring only one link on console Firebase?

Question

When the app is not installed, and the user open the dynamic link, the app store is well opened, but once installed, if I click on "open", it open the apps, it says a message "link paste from the navigator", but the dynamic link is only launched without the parameters

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {

Here is the function:

     func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
          let handled = DynamicLinks.dynamicLinks()
            .handleUniversalLink(userActivity.webpageURL!) { dynamiclink, error in
              // ...
                print(dynamiclink!)
                
                let urlStr: String = (dynamiclink?.url?.absoluteString.lowercased())!
                //  UserDefaults.standard.set(urlStr, forKey: "url")
                
                if (urlStr.contains("test?code=azerty")) {
                    UserDefaults.standard.set(urlStr, forKey: "url")
                    
                    let str: String = UserDefaults.standard.value(forKey: "url") as! String
                    if (str.contains("test?code=azerty"))
                       {
                        let alert = UIAlertController(title: "test", message: str, preferredStyle: .alert)
                        
                        alert.addAction(UIAlertAction(title: "OK", style:  .default, handler: { action in
                            switch action.style{
                            case .default:
                                print("default")
                                
                            case .cancel:
                                print("cancel")
                                
                            case .destructive:
                                print("destructive")
                                
                            }}))
                        
                        let navigationController = application.windows[0].rootViewController as! UINavigationController
                        let activeViewCont = navigationController.visibleViewController
                        activeViewCont?.view.isUserInteractionEnabled = false
                        //activeViewCont!.present(alertController, animated: true, completion: nil)
                        DispatchQueue.main.asyncAfter(deadline: .now() + 5.0, execute: {
                            activeViewCont!.present(alert, animated: true, completion: nil)
                        })
                       
                       }
                }
                
            }
    
          return handled
        }
 func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        print(url)
        print("handleOpenURL")
        
        //let urlStr: String = url.absoluteString.replacingOccurrences(of: "colas://", with: "")
        let urlStr: String = url.absoluteString.lowercased()
        //  UserDefaults.standard.set(urlStr, forKey: "url")
        
        if (urlStr.contains("test?code=azerty")) {
            UserDefaults.standard.set(urlStr, forKey: "url")
            
            let str: String = UserDefaults.standard.value(forKey: "url") as! String
            if (str.contains("test?code=azerty"))
               {
                let alert = UIAlertController(title: "test", message: str, preferredStyle: .alert)

                    switch action.style{
                    case .default:
                        print("default")

                    case .destructive:
                        print("destructive")
                        
                    }}))

How can I get the function fired, just after install the application from the app store, with the dynamic link containing the parameters?

Message:

xxxx.xxxxxxxxx.myapp://google/link/?deep_link_id=https://myapp.page.link/&match_type=unique&utm_medium=dynamic_link&request_ip_version=IP_V4&utm_source=firebase&match_message=Link is uniquely matched for this device.

Answer 1

the two problems were :
1/ the good writing of the dynamical url : 

https://yourapp.page.link/?link=https://yourapp.com/test=12345&isi=14602xxxxx&ibi=com.xxxx.yourapp

This is the good way to create the url

2/ The parameter in info.plist in Xcode is important : 

<key>FirebaseDynamicLinksCustomDomains</key>
    <array>
        <string>https://yourapp.com/link</string>
    </array>
