Before, I used AdMob's banner ad and open app ad in an iOS app. Now, I want to show its Rewarded interstitial ads. I checked the (relevant web page of AdMob), but the examples on this page are all in Objective C language. I am not familiar with Objective C language. Can anyone provide guidance in Swift language? Thanks in advance.

here is a swift example taken from official AdMob documentation

this is Dedicated test ad unit ID for iOS interstitials: ca-app-pub-3940256099942544/4411468910

Load an ad

import GoogleMobileAds
import UIKit

class ViewController {

  private var interstitial: GADInterstitialAd?

  func viewDidLoad() {
    super.viewDidLoad()
    let request = GADRequest()
    GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",
                                request: request,
                      completionHandler: { [self] ad, error in
                        if let error = error {
                          print("Failed to load interstitial ad with error: \(error.localizedDescription)")
                          return
                        }
                        interstitial = ad
                      }
    )
  }
}

Register for callbacks

class ViewController: GADFullScreenContentDelegate {

  private var interstitial: GADInterstitialAd?

  func viewDidLoad() {
    super.viewDidLoad()
    let request = GADRequest()
    GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",
                                request: request,
                      completionHandler: { [self] ad, error in
                        if let error = error {
                          print("Failed to load interstitial ad with error: \(error.localizedDescription)")
                          return
                        }
                        interstitial = ad
                        interstitial?.fullScreenContentDelegate = self
                      }
    )
  }

  /// Tells the delegate that the ad failed to present full screen content.
  func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {
    print("Ad did fail to present full screen content.")
  }

  /// Tells the delegate that the ad presented full screen content.
  func adDidPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    print("Ad did present full screen content.")
  }

  /// Tells the delegate that the ad dismissed full screen content.
  func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    print("Ad did dismiss full screen content.")
  }
}

Display the ad

@IBAction func doSomething(_ sender: Any) {
  if interstitial != nil {
    interstitial.present(fromRootViewController: self)
  } else {
    print("Ad wasn't ready")
  }
}
