How can I use the UIViewController in Swiftui (Store Kit - LoadProduct)?

Question

I would like to open the app store with my app inside my swiftui app, e.g with sheet.

I found this article Link:

Here are my code for SKStoreProductWithClosure.swift class.

import StoreKit

class ViewController: UIViewController {
    
    let appURL = URL(string: "https://itunes.apple.com/app/idxxxxxxxx")!
    let productID = xxxxxxxxx

    func openAppStore() {
        
        let appStoreVC = SKStoreProductViewController()
        appStoreVC.delegate = self
        let parametersDictionary = [SKStoreProductParameterITunesItemIdentifier: productID]

        appStoreVC.loadProduct(withParameters: parametersDictionary) { loaded, error in
            guard error == nil, loaded else {
                return
            }
            self.present(appStoreVC, animated: true)
        }
    }
}

extension ViewController: SKStoreProductViewControllerDelegate {
    func productViewControllerDidFinish(_ viewController: SKStoreProductViewController) {
        viewController.dismiss(animated: true)
    }
}

Here are my current ContentView.

import SwiftUI

struct ContentView: View {
    
    @State private var showAppStore = false
    
    var body: some View {
    
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundStyle(.tint)
                .onTapGesture {
                    self.showAppStore.toggle()
                }
                .sheet(isPresented: $showAppStore) {
                    // Here I need the openAppStore() function
                }
        }
        .padding()
        
    }
}

#Preview {
    ContentView()
}

But I have big trouble to implement the class into my ContentView. I had some solution but then sheet comes up twice (one blank and after the app store sheet)

May I ask you, give me some help or hints.

Many thanks in advance. Sven

I expect to click on the image and the sheet with the app store content of my app comes up.

Answer 1

use uiviewcontrollerrepresentable to connect viewcontroller and view

struct MyView: UIViewControllerRepresentable { 

    func makeUIViewController(context: Context) -> MyViewController {
        return ViewController()  
    }

    func updateUIViewController(_ uiViewController: MyViewController, context: Context) {}
}

and you can call openAppStore() inside viewdidappear
