iOS Swift AddMob无法识别的选择器发送到实例

Question

 import UIKit
 import Firebase
 class MyPage: UIViewController ,UITextViewDelegate,UINavigationControllerDelegate{
     var interstitial: GADInterstitial!
        fileprivate func createAndLoadInterstitial() {
            interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
            interstitial.delegate = self
            let request = GADRequest()
            // Request test ads on devices you specify. Your test device ID is printed to the console when
            // an ad request is made.
            request.testDevices = [ kGADSimulatorID, "2077ef9a63d2b398840261c8221a0c9a" ]
            interstitial.load(request)
        }
    override func viewDidLoad() {
        super.viewDidLoad()
         createAndLoadInterstitial()
    }
}

extension MyPage:GADInterstitialDelegate{
    /// Tells the delegate an ad request succeeded.
    func interstitialDidReceiveAd(_ ad: GADInterstitial) {
        print("interstitialDidReceiveAd")
    }

    /// Tells the delegate an ad request failed.
    func interstitial(_ ad: GADInterstitial, didFailToReceiveAdWithError error: GADRequestError) {
        print("interstitial:didFailToReceiveAdWithError: \(error.localizedDescription)")
    }

    /// Tells the delegate that an interstitial will be presented.
    func interstitialWillPresentScreen(_ ad: GADInterstitial) {
        print("interstitialWillPresentScreen")
    }

    /// Tells the delegate the interstitial is to be animated off the screen.
    func interstitialWillDismissScreen(_ ad: GADInterstitial) {
        print("interstitialWillDismissScreen")
    }

    /// Tells the delegate the interstitial had been animated off the screen.
    func interstitialDidDismissScreen(_ ad: GADInterstitial) {
        print("interstitialDidDismissScreen")
    }

    /// Tells the delegate that a user click will open another app
    /// (such as the App Store), backgrounding the current app.
    func interstitialWillLeaveApplication(_ ad: GADInterstitial) {
        print("interstitialWillLeaveApplication")
    }
}

并添加Build Setting Debug和Release -ObjC

除此之外我还能做些什么吗？

如果我只是加载MyPage引发此异常

这是我的问题。

我按照这个例子跟着它。为什么不？
