Code Samples & Details

Then in my code I tried all this variants:

I tried this:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // Set the trackings to true in test mode
        Settings.setAdvertiserTrackingEnabled(true)
        Settings.isAdvertiserIDCollectionEnabled = true
        Settings.isAutoLogAppEventsEnabled = true

        // Initialize the Facebook SDK
        ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

        Settings.shared.isAdvertiserIDCollectionEnabled = false
        Settings.shared.isAdvertiserTrackingEnabled = false
        Settings.shared.isAutoLogAppEventsEnabled = false
}

Then on the primary ViewController:

class SomePrimaryViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        setupUI()
    }

    @available(iOS 14.5.1, *)
    private func presentTransparencyMode() {
        ATTrackingManager.requestTrackingAuthorization { status in
            
             switch status
            {
            case .authorized:
                
                // Tracking authorization dialog was shown
                // and we are authorized
                print("Authorized")
                
                // Now that we are authorized we can get the IDFA
                print(ASIdentifierManager.shared().advertisingIdentifier)
                
                // Get the Deferred link
                 DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
                    self.setupDefferedLink()
                }

            case .denied:
                // Tracking authorization dialog was
                // shown and permission is denied
                print("Denied")
            case .notDetermined:
                // Tracking authorization dialog has not been shown
                print("Not Determined")
            case .restricted:
                print("Restricted")
            @unknown default:
                print("Unknown")
            }
        }
        
    }

    private func setupDefferedLink() {
     
        // Set the trackings to true in test mode
        Settings.shared.isAdvertiserIDCollectionEnabled = true
        Settings.shared.isAdvertiserIDCollectionEnabled = true
        Settings.shared.isAutoLogAppEventsEnabled = true

        let id = ASIdentifierManager.shared().advertisingIdentifier.uuidString
        let request = GraphRequest(graphPath: "/971082983006874/activities", parameters: ["event": "DEFERRED_APP_LINK",
                                                                                          "advertiser_id": id,
                                                                                          "application_tracking_enabled": "1",
                                                                                          "advertiser_tracking_enabled": "1"], httpMethod: .post)
        
        request.start { [unowned self] connection, result, error in
            if let result = result as? NSDictionary {
                print(result as Any)
                // It prints a dictionary with a key `success` with  value `true` 
                // and nothing about the url
            }
        }
        
        AppLinkUtility.initialize()
        AppLinkUtility.fetchDeferredAppLink { (url, error) in
            if let url = url {
                print(url)
            }
            print(error as Any)
            // It prints:
            // ATTrackingManager.AuthorizationStatus must be `authorized` for deferred deep linking to work. Read more at:         https://developer.apple.com/documentation/apptrackingtransparency
           // That is an Error of the SDK, because the permission has been granted
        }
        
    }

}

No matter which variant you try, the result is always the same, url = nil

I have the same issue, url is nil always

[julioarregoitia]

Apparently the issue it's with IDFA that always is 00000000-0000-0000-0000-000000000000, hopefully when this problem is solved this issue disappear:
