To get test ads on this device, call: request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATOR_ID, nil];

Question

While i test Admob in simulator, it throws below error

To get test ads on this device, call: request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATO

Answer 1

Since the newest update the request.testDevices has been replaced with:

GADMobileAds.sharedInstance().requestConfiguration.testDeviceIdentifiers

I have gotten it to work with this:

GADMobileAds.sharedInstance().requestConfiguration.testDeviceIdentifiers = [(kGADSimulatorID as! String)]

[EDIT]

In my app delegate I am using this code:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
    // use this for production 
    GADMobileAds.sharedInstance().start(completionHandler: nil)
    // use this for testing 
    GADMobileAds.sharedInstance.requestConfiguration.testDeviceIdentifiers = [ kGADSimulatorID ]
        
    return true
}

This is for Swift 5, iOS 13 and Google-Mobile-Ads-SDK (7.58.0)
