Code snippet showing how to use AdMob with SwiftUI (updated for Jan 2021)

AdMob Interstitial Ad SwiftUI

// First create a dedicated class for this 
```
import SwiftUI
import GoogleMobileAds

class Interstitial : NSObject,GADFullScreenContentDelegate{
   
    var interstitial : GADInterstitialAd = GADInterstitialAd.init()
    
    func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
        print("Ad dismissed")
        loadInterstitial()
    }
    
    func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {
        print(error.localizedDescription)
    }
        
    let adUnitID: String = AdUnit.homeInterstitial.unitID
    
    override init() {
        super.init()
        loadInterstitial()
    }
    
    func loadInterstitial(){
        let request = GADRequest()
        
        GADInterstitialAd.load(withAdUnitID: adUnitID, request: request) { (ad, err) in
            if(err !=  nil){
                print(String(describing:err?.localizedDescription))
            }
            else{
            //You can show straight away if you want
            // My use case was using a Button 
//                self.showAd()
                self.interstitial = ad!
                self.interstitial.fullScreenContentDelegate = self
            }
        }
    }

    func showAd(){
        let root = UIApplication.shared.windows.first?.rootViewController
        self.interstitial.present(fromRootViewController: root!)
    }
    

}

// And now in Content View whenever your are required to show the add
```
struct ContentView: View {
     
    
    var interstitial : Interstitial = Interstitial()
    
    var body: some View {
            VStack {
                Button("Tap Me"){
                    self.interstitial.showAd()
                }
            }
    }
    
}



```
