You need to declare and set up a GADBannerView and add it to your view controller. You won't need a UIWindow. Use this code:
import GoogleMobileAds
import UIKit
class ViewController: UIViewController {
var bannerView: GADBannerView!
override func viewDidLoad() {
super.viewDidLoad()
// In this case, we instantiate the banner with desired ad size.
bannerView = GADBannerView(adSize: kGADAdSizeBanner)
addBannerViewToView(bannerView)
}
func addBannerViewToView(_ bannerView: GADBannerView) {
bannerView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(bannerView)
view.addConstraints(
[NSLayoutConstraint(item: bannerView,
attribute: .bottom,
relatedBy: .equal,
toItem: bottomLayoutGuide,
attribute: .top,
multiplier: 1,
constant: 0),
NSLayoutConstraint(item: bannerView,
attribute: .centerX,
relatedBy: .equal,
toItem: view,
attribute: .centerX,
multiplier: 1,
constant: 0)
])
}
}
which was taken from here: https://developers.google.com/admob/ios/banner.
Also make sure to set the ad unit ID and the delegate:
override func viewDidLoad() {
super.viewDidLoad()
...
bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
bannerView.rootViewController = self
bannerView.load(GADRequest())
}
But again, you'll everything you need in the official guide.
