View won't show when calling by function in SwiftUI - swift

Question

I have this problem. I'm trying to show Ads in my app using AdMob. It all works fine (i did some debug) but the view containing the video is not showing... I can't figure out why it's not showing on the top of my content.
Here is the the class that calls and opens the view with ads:
import SwiftUI
import GoogleMobileAds
import UIKit
class Rewarded: NSObject, GADRewardedAdDelegate, ObservableObject{
#Published var adLoaded: Bool = false
var rewardedAd:GADRewardedAd = GADRewardedAd(adUnitID: "ca-app-pub-3940256099942544/1712485313")
var rewardFunction: (() -> Void)? = nil
override init() {
super.init()
LoadRewarded()
}
func LoadRewarded(){
let req = GADRequest()
self.rewardedAd.load(req) { error in
if error != nil {
self.adLoaded = false
print("Ad not loaded")
} else {
self.adLoaded = true
print("Ad loaded")
}
}
}
func showAd(rewardFunction: #escaping () -> Void){
if self.rewardedAd.isReady {
print("Ad is ready to show")
self.rewardFunction = rewardFunction
if let root = UIApplication.shared.windows.first?.rootViewController {
self.rewardedAd.present(fromRootViewController: root, delegate: self)
print("Presenting")
} else {
print("Failed to open ad")
}
} else {
print("Ad not ready to show")
}
}
func rewardedAd(_ rewardedAd: GADRewardedAd, userDidEarn reward: GADAdReward) {
if let rf = rewardFunction {
rf()
}
}
func rewardedAdDidDismiss(_ rewardedAd: GADRewardedAd) {
self.rewardedAd = GADRewardedAd(adUnitID: "ca-app-pub-3940256099942544/1712485313")
LoadRewarded()
}
}
And here is the SwiftUI portion of the code that calls the function of the class:
Button {
self.rewardAd.showAd(rewardFunction: {
// GIVE REWARD HERE
})
} label: {
Text("Watch Ad")
.foregroundColor(Color.white)
.font(.custom(customFont, size: 17))
.fontWeight(.bold)
}
Also the console doesn't print any error...
Does anybody know why it is not showing?
Thank you all

This works for me. I had a heck of a time getting this to work and tried following all of the examples I could find, finally landed on this.
func showAd(rewardFunction: #escaping () -> Void){
if let ad = rewardedAd {
self.rewardFunction = rewardFunction
if let root = UIApplication.shared.windows.first?.rootViewController {
ad.present(fromRootViewController: root, userDidEarnRewardHandler: {
let reward = ad.adReward
// reward the user
})
}
else {
print("Error presenting ad")
}
}
else{
print("Ad Not Ready")
}
}
