iOS Native AdMob

Trying to show Google Ad in UITablewViewCell using the Native Google Ad documentation. But, I kept getting

Failed Ad Request: Error Domain=com.google.admob Code=1 "Request Error: No ad to show." UserInfo={NSLocalizedDescription=Request Error: No ad to show.} 

This is my configuration:

I need to display customised Ads at the 3rd row of the table view.

GoogleAdBannerView.swift import UIKit import GoogleMobileAds

class GoogleAdBannerView: GADUnifiedNativeAdView { let modMediaView: GADMediaView = { let mediaView = GADMediaView() mediaView.translatesAutoresizingMaskIntoConstraints = false return mediaView }() let bannerImageView: UIImageView = { let imageview = UIImageView() imageview.translatesAutoresizingMaskIntoConstraints = false return imageview }() let adTitle: UILabel = { let label = UILabel() label.font = UIFont.mySFMedium(ofSize: 16) label.textColor = UIColor.black.withAlphaComponent(0.87) label.translatesAutoresizingMaskIntoConstraints = false return label }() let refreshBtn: UIButton = { let btn = UIButton() btn.setTitle("Refresh", for: .normal) btn.setTitleColor(.blue, for: .normal) btn.layer.cornerRadius = 2 btn.layer.borderWidth = 1 btn.layer.borderColor = UIColor(red:0.85, green:0.85, blue:0.85, alpha:1.0).cgColor btn.translatesAutoresizingMaskIntoConstraints = false return btn }() required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder)! setupViews() } override init(frame: CGRect) { super.init(frame: frame) setupViews() } func setupViews() { mediaView = modMediaView iconView = bannerImageView headlineView = adTitle addSubview(mediaView!) addSubview(iconView!) addSubview(headlineView!) addSubview(refreshBtn) mediaView?.widthAnchor.constraint(equalTo: widthAnchor, constant: -32).isActive = true mediaView?.heightAnchor.constraint(equalToConstant: 160).isActive = true mediaView?.centerXAnchor.constraint(equalTo: centerXAnchor).isActive = true mediaView?.topAnchor.constraint(equalTo: topAnchor, constant: 16).isActive = true iconView?.widthAnchor.constraint(equalToConstant: 40).isActive = true iconView?.heightAnchor.constraint(equalToConstant: 40).isActive = true iconView?.leftAnchor.constraint(equalTo: leftAnchor, constant: 16).isActive = true iconView?.topAnchor.constraint(equalTo: mediaView!.bottomAnchor, constant: 16).isActive = true headlineView?.leftAnchor.constraint(equalTo: iconView!.rightAnchor, constant: 16).isActive = true headlineView?.topAnchor.constraint(equalTo: iconView!.topAnchor).isActive = true headlineView?.rightAnchor.constraint(equalTo: rightAnchor, constant: -16).isActive = true refreshBtn.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -16).isActive = true refreshBtn.heightAnchor.constraint(equalToConstant: 45).isActive = true refreshBtn.widthAnchor.constraint(equalTo: widthAnchor, multiplier: 2/3, constant: -32).isActive = true refreshBtn.leftAnchor.constraint(equalTo: leftAnchor, constant: 16).isActive = true } } 

The table view cell:

FieldListLiteAdCell.swift

import UIKit import GoogleMobileAds class FieldListLiteAdCell: UITableViewCell, GADUnifiedNativeAdLoaderDelegate { let mainView: GoogleAdBannerView = { let view = GoogleAdBannerView() view.backgroundColor = .white view.translatesAutoresizingMaskIntoConstraints = false return view }() var controller: FieldListView? { didSet { if let _ = controller { fetchAds() } } } var adLoader: GADAdLoader! override init(style: UITableViewCellStyle, reuseIdentifier: String?) { super.init(style: style, reuseIdentifier: reuseIdentifier) self.backgroundColor = UIColor.white self.selectionStyle = .none addSubview(mainView) mainView.widthAnchor.constraint(equalTo: widthAnchor).isActive = true mainView.heightAnchor.constraint(equalTo: heightAnchor).isActive = true mainView.centerXAnchor.constraint(equalTo: centerXAnchor).isActive = true mainView.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true mainView.refreshBtn.addTarget(self, action: #selector(refreshFieldAds(_:)), for: .touchUpInside) fetchAds() } @IBAction func refreshFieldAds(_ sender: UIButton) { fetchAds() } private func fetchAds() { adLoader = GADAdLoader(adUnitID: "ca-app-pub-3940256099942544/3986624511", rootViewController: controller, adTypes: [GADAdLoaderAdType.unifiedNative], options: nil) adLoader.delegate = self let adRequest = GADRequest() adRequest.testDevices = [kGADSimulatorID] adLoader.load(adRequest) // adLoader.load(GADRequest()) } func adLoader(_ adLoader: GADAdLoader, didReceive nativeAd: GADUnifiedNativeAd) { mainView.nativeAd = nativeAd nativeAd.delegate = self print("Ad has been received.") mainView.mediaView?.mediaContent = nativeAd.mediaContent (mainView.iconView as? UIImageView)?.image = nativeAd.icon?.image (mainView.headlineView as? UILabel)?.text = nativeAd.headline } func adLoaderDidFinishLoading(_ adLoader: GADAdLoader) { } func adLoader(_ adLoader: GADAdLoader, didFailToReceiveAdWithError error: GADRequestError) { print("Failed Ad Request: ", error) } required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } } // MARK: - GADUnifiedNativeAdDelegate implementation extension FieldListLiteAdCell: GADUnifiedNativeAdDelegate { func nativeAdDidRecordClick(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } func nativeAdDidRecordImpression(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } func nativeAdWillPresentScreen(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } func nativeAdWillDismissScreen(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } func nativeAdDidDismissScreen(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } func nativeAdWillLeaveApplication(_ nativeAd: GADUnifiedNativeAd) { print("\(#function) called") } } 

I don't know what I am doing wrong. Tried multiple App Unit ID, created multiple accounts, waited for more than 2hrs as suggested by some StackOverflow answers. Ensured device ID is added to the request.

Edit 1

Someone marked the question as possible duplicate, with an un-verified suggestion. I had to make a sample app that implement this same logic and it's working fine.

I've reviewed the Info.plist file to ensure Allow Arbitrary Loads is set to YES. I'm yet to identify the reason behind the error.

Sample GoogleAd Native Implementation

Any help would be appreciated. Thanks.
