admob interstitial ad is never ready

Question

i have this game and i created 3 funcions in my gameviewcontroller and here they are

    func getInterstitialAd(){
    interstitial = GADInterstitial(adUnitID: "ca-app-pub-1782852253088296/5018877964")
    let requestInterstitial = GADRequest()
    interstitial.load(requestInterstitial)
}



func showAd() {

    if (interstitial.isReady == true){
        interstitial.present(fromRootViewController: GameViewController())
    }else{
        print("ad wasn't ready")
        interstitial = createAd()
    }



}

func createAd() -> GADInterstitial{
    let interstital = GADInterstitial(adUnitID: "ca-app-pub-1782852253088296/5018877964")
    interstitial.load(GADRequest())
    return interstital
}

and in one of my scene called StartMenu , i call those function

   var viewController: GameViewController!

and then i call the functions

       viewController.getInterstitialAd()
        viewController.showAd()

but it always returns ad not ready , and false for interstitial.isReady, but also the getInterstitial function is always called .

can someone help with that please

Create a new swift file AdMobDelegate :-

import UIKit
import GoogleMobileAds

class AdMobDelegate: NSObject, GADInterstitialDelegate {

    var interstitialView: GADInterstitial!

    func createAd() -> GADInterstitial {
        interstitialView = GADInterstitial(adUnitID: "Your Key")
        interstitialView.delegate = self
        let request = GADRequest()
        interstitialView.loadRequest(request)
        return interstitialView
    }

    func showAd() {
        if interstitialView != nil {
            if (interstitialView.isReady == true){
                interstitialView.present(fromRootViewController:currentVc)
            } else {
                print("ad wasn't ready")
                interstitialView = createAd()
            }
        } else {
            print("ad wasn't ready")
            interstitialView = createAd()
        }
    }

    func interstitialDidReceiveAd(ad: GADInterstitial!) {
        print("Ad Received")
        if ad.isReady {
            interstitialView.present(fromRootViewController: currentVc)
        }
   }

    func interstitialDidDismissScreen(ad: GADInterstitial!) {
        print("Did Dismiss Screen")
    }

    func interstitialWillDismissScreen(ad: GADInterstitial!) {
        print("Will Dismiss Screen")
    }

    func interstitialWillPresentScreen(ad: GADInterstitial!) {
        print("Will present screen")
    }

    func interstitialWillLeaveApplication(ad: GADInterstitial!) {
        print("Will leave application")
    }

    func interstitialDidFailToPresentScreen(ad: GADInterstitial!) {
        print("Failed to present screen")
    }

    func interstitial(ad: GADInterstitial!, didFailToReceiveAdWithError error: GADRequestError!) {
        print("\(ad) did fail to receive ad with error \(error)")
    }
}

Now you can use the object of this delegate class in other files as follows :-

//Define admobdelegate as global variable
var admobDelegate = AdMobDelegate()

//Declare a global variable currentVc to hold reference to current view controller
var currentVc: UIViewController!

class abc1: UIViewController {

    override func viewdidload() {
        super.viewdidload()
        currentVc = self
        admobDelegate.showAd()
    }

    override func viewDidAppear() {
        super.viewDidAppear()
        currentVc = self
    }
}

class abc2: UIViewController {

    override func viewdidload() {
        super.viewdidload()
        currentVc = self
        admobDelegate.showAd()
    }

    override func viewDidAppear() {
        super.viewDidAppear()
        currentVc = self
    }
}

Code is in Swift 2.2. Write your equivalent code in swift 3 in case of syntax error.
