App Tracking Transparency Dialog does not appear on iOS

Question

Apple reviewer has just rejected my app since ATT request doesn't appear: "We are unable to locate the App Tracking Transparency permission request when reviewed on iOS 15.0.1."

My code is as shown below:

if #available(iOS 14, *) {
  ATTrackingManager.requestTrackingAuthorization { (status) in
    //print("IDFA STATUS: \(status.rawValue)")
    FBAdSettings.setAdvertiserTrackingEnabled(true)
  }
}

I implemented this code both in AppDelegate didFinishLaunchingWithOptions and viewDidLoad. ATT permission request appear on iOS 14, but not in iOS 15.

Have you set NSUserTrackingUsageDescription in Info.plist? https://developer.apple.com/documentation/bundleresources/information_property_list/nsusertrackingusagedescription — Rob Napier, Oct 02 '21 at 20:50
Of course, otherwise, permission request wouldn't have appeared on iOS 14 — Ömer Karaca, Oct 02 '21 at 21:35

Damn it I fixed it:( This is all about the iOS alert system. I was requesting App Tracking Transparency after a notification request was asked. Once the notification request alert closed, the ATT alert needed to have appeared. It was working fine on iOS 14, but on iOS 15 to display an alert right after another one, it is needed to have a delay period between each other.

Edit: Here is my code that display two alert respectively:

 func setNotification(){
    //Ask for notification permission
    let n = NotificationHandler()
    n.askNotificationPermission {
        //n.scheduleAllNotifications()
        
        //IMPORTANT: wait for 1 second to display another alert
        DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
            if #available(iOS 14, *) {
              ATTrackingManager.requestTrackingAuthorization { (status) in
                //print("IDFA STATUS: \(status.rawValue)")
                //FBAdSettings.setAdvertiserTrackingEnabled(true)
              }
            }
        }
    }
}

And for your convenience here is my NotificaitionHandler class:

import UserNotifications

class NotificationHandler{
//Permission function
func askNotificationPermission(completion: @escaping ()->Void){
    
    //Permission to send notifications
    let center = UNUserNotificationCenter.current()
    // Request permission to display alerts and play sounds.
    center.requestAuthorization(options: [.alert, .badge, .sound])
    { (granted, error) in
        // Enable or disable features based on authorization.
        completion()
    }
}

i was try it and i was publish with this answer with my own project on app store. but, i was suprisely it rejected by apple. – Michael Fernando Nov 08 '21 at 07:36
And if it takes 1.5 sec? What you should be checking is the `UIApplication.shared.applicationState`, it's probably `inactive` when you call it. A better solution would be to call it in `AppDelegate` `applicationDidBecomeActive`, or add notification for `UIApplication.didBecomeActiveNotification` and request authentication there – bauerMusic Nov 22 '21 at 12:52
Ya, same case exactly with me. 2 requests for permissions. notification and tracking. – hasan Nov 25 '21 at 08:00
I tried all possible solutions of this page (as of 10th June '22) and had no luck yet. I'm building my iOS app with Flutter. – Vega180 Jun 10 '22 at 14:45
what the?? something i was realize after read this and evaluate with apple tester team every one month. – Michael Fernando Oct 10 '22 at 02:19

An Apple person suggests that you request it through applicationDidBecomeActive(_:) in AppDelegate. That's how I fixed the issue for iOS.

import UIKit
import AppTrackingTransparency

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
    func applicationDidBecomeActive(_ application: UIApplication) {
        if #available(iOS 15.0, *) {
            ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
                
            })
        }
    }
}

This doesn't work for me! – Ömer Karaca Oct 05 '21 at 18:19

We were calling `requestTrackingAuthorization` from the `applicationDidFinishLaunching` and on the iOS 15 app is `inactive`. Moving it to `applicationDidBecomeActive` resolved our issue. – Zapko Oct 15 '21 at 05:30

worked for me, thank you – Leon Jakonda Oct 27 '21 at 14:54

You can call it from anywhere by creating a notification for didBecomeActive: `NotificationCenter.default.addObserver(self, selector: #selector(showTrackingAction), name: UIApplication.didBecomeActiveNotification, object: nil)` – bauerMusic Nov 22 '21 at 12:58

This is the correct answer, and I can also verify apple recommends this as well. – Lucas Dahl Dec 09 '21 at 21:08
anyway, this code it will be worked for any flutter iOS Projects? – Michael Fernando Oct 10 '22 at 03:15

I've changed to call the request from

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
}

to

@available(iOS 13.0, *)
func sceneDidBecomeActive(_ scene: UIScene) {
    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
        self.requestPermission()
    }
}

func requestPermission() {
    if #available(iOS 15.0, *) {
            ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
                switch status {
                case .authorized:
                    // Tracking authorization dialog was shown
                    // and we are authorized
                    print("Authorized")
                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:
                   
                }
            })
        }
    }
}

Here's how to call the request in SwiftUI when app becomes active:

@main
struct MyApp: App {
    @Environment(\.scenePhase) var scenePhase
    
    var body: some Scene {
        WindowGroup {
            MainView()
                .onChange(of: scenePhase, perform: { newValue in
                    if newValue == .active {
                        ATTrackingManager.requestTrackingAuthorization { status in
                            // do something
                        }
                    }
                })
        }
    }
}

I've changed to call the request from the AppDelegate's applicationDidBecomeActive method and it worked!

The popup is being presented on the first app launch on iOS15.

In my case, Settings -> Privacy & Security -> Tracking -> "Allow Apps to Request to Track" was off on the device.

After turn it on, I was able to see dialog.

It's Flutter app, real device, iOS 16.5
