Google AdMob integration in SwiftUI

Question

I found nowhere an example how to integrate it with swiftui. Does anybody found a tutorial? The problem is the part with the root controller.

Answer 1

You should use UIViewRepresentable instead of UIViewControllerRepresentable.

I implemented the Adaptive banner with this code:

struct AdView : UIViewRepresentable {
    @State private var banner: GADBannerView = GADBannerView(adSize: kGADAdSizeBanner)
    
    func makeUIView(context: UIViewRepresentableContext) -> GADBannerView {
        #if DEBUG
        banner.adUnitID = "ca-app-pub-debug"
        #else
        banner.adUnitID = "ca-app-pub-prod"
        #endif

        guard let rootViewController = UIApplication.shared.windows.first?.rootViewController else {
            return banner
        }
        
        banner.rootViewController = rootViewController
        
        let frame = { () -> CGRect in
            return banner.rootViewController!.view.frame.inset(by: banner.rootViewController!.view.safeAreaInsets)
        }()
        let viewWidth = frame.size.width

        banner.adSize = GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(viewWidth)

        banner.load(GADRequest())
        return banner
    }
    
    func updateUIView(_ uiView: GADBannerView, context: UIViewRepresentableContext) {
    }
}

Then you can call on your Stack using

AdView().frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: 300)
                .frame(width: kGADAdSizeBanner.size.width, height: kGADAdSizeBanner.size.height)
