load interstitial ad on IBAction button

Question

When my callButton is clicked it rings a phone number, I want to display my interstitial ad before the call is made. I have tested my ad on the "IBAction function ad" button and it works on the button but when I call it on the callButton func it will not work and goes straight to making a call.

class ProfilePageViewController: UIViewController, MFMessageComposeViewControllerDelegate, UITableViewDelegate, UIAlertViewDelegate, GADInterstitialDelegate {

@IBAction func ad(_ sender: Any) {
    if self.interstitialAd.isReady {
        self.interstitialAd.present(fromRootViewController: self)
    }
}

@IBAction func callButton(_ sender: Any) {

    if let contactopt = contact{

        if let url = NSURL(string: "tel://\(contactopt)") {
            //    UIApplication.shared.openURL(url as URL)
            UIApplication.shared.open(url as URL, options: [:], completionHandler: nil)
        }
    }
}

var interstitialAd: GADInterstitial!

func reloadInterstitialAd() -> GADInterstitial {
    var interstitial = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
    interstitial.delegate = self
    interstitial.load(GADRequest())
    return interstitial
}

func interstitialDidDismissScreen(ad: GADInterstitial!) {
    self.interstitialAd = reloadInterstitialAd()
}

func interstitialDidDismissScreen(_ ad: GADInterstitial) {
    interstitialAd = reloadInterstitialAd()
}
override func viewDidLoad() {
    self.interstitialAd = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
    let request = GADRequest()
    request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"]
    self.interstitialAd.load(request)
    self.interstitialAd = reloadInterstitialAd()

    super.viewDidLoad()

}

}

Of course it goes to making a call. That's what you're telling it to do with UIApplication.shared.open.

Make the call once the ad has been dismissed in interstitialDidDismissScreen. Also check to see if there is an ad to present, interstitialAd.isReady. If there is no ad to present go straight to making the call.

You're also doing the same thing twice in your viewDidLoad:

// Sets up an ad
self.interstitialAd = GADInterstitial(adUnitID: "ca-app-pub-/6966780536")
let request = GADRequest()
request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"]
self.interstitialAd.load(request)
// Creates a new ad
self.interstitialAd = reloadInterstitialAd()

Just call self.interstitialAd = reloadInterstitialAd().
