ios - Change background color of Google AdMob Native Ad Swift

Question

I Have implemented Google AdMob's Native Ads primarily because it's easy to customize but I can't seem to find out how to change the background color of the ad itself, I've looked everywhere and tried it all but haven't found an answer yet.

This is the code I'm using to style the Ad

func adLoader(_ adLoader: GADAdLoader, didReceive nativeAd: GADUnifiedNativeAd) {
    templateView?.nativeAd = nativeAd
    let styles : [GADTNativeTemplateStyleKey: NSObject] = [
        .mainBackgroundColor: UIColor.red,
        .primaryFontColor: UIColor(named: "Primary Text")!,
        .secondaryFontColor: UIColor(named: "Secondary Text")!,
        .tertiaryFontColor: UIColor(named: "Secondary Text")!,
        .primaryFont: UIFont.rounded(ofSize: 17, weight: .semibold),
        .secondaryFont: UIFont.rounded(ofSize: 15, weight: .medium),
        .tertiaryFont: UIFont.rounded(ofSize: 15, weight: .medium),
        .callToActionBackgroundColor: UIColor(.accentColor),
        .cornerRadius: NSNumber(floatLiteral: 10.0)
    ]
    templateView?.styles = styles
    templateView?.layer.borderColor = UIColor.clear.cgColor
}

And this is a screenshot of the ad in the simulator

I switched to dark mode because my goal is to conform the background of the ad to the background of the view.

Answer 1

I Had to change the view directly by going in the template files and changing the background color to clear
