Reporting StoreKitErrors with ProductView (StoreKit2)

Testing in-app purchase with the App Store Connect / Xcode configuration file allows testing of approximately 43 non-consumable product errors.

Testing my non-consumable in-app purchase with the new ProductView on my app for these various faults doses’t appear to be very promising.

Loading errors: all result in a blank screen and spinning wheel without producing an alert.

Purchase errors: Some of these work producing readable comments. Purchase (not entitled) and Purchase (system error) just produce alert boxes with an OK button. Purchase (network) produces the alert “The operation could not be completed. (NSURLErrorDomain error - 1009.)”

Verification errors, App Store Sync, and App Transaction errors: These purchases are successful and produce no alerts.

Am I missing a method that handles these errors? With ProductView do I need to use a do / catch block in my viewModel? Can I release this app for review working like this?

struct StoreView: View {
    
    @StateObject private var store = StoreModel()
    
    var body: some View {
        
        GeometryReader { g in
            VStack {
                Spacer()
                
                Text("\(mainTitle)")
                    .font(.title)
                    .padding(.bottom, 25)
                
                ProductView(id: "xxxx") { _ in
                    
                    Image(systemName: "xxxx")
                        .resizable()
                        .scaledToFit()
                    
                } placeholderIcon: {
                    ProgressView()
                }
                .productViewStyle(.large)
                
                .overlay(
                    RoundedRectangle(cornerRadius: 20)
                        .stroke(Color( "darkGreen"), lineWidth: 5)
                        .frame(width: g.size.width * 0.90, height: g.size.height * 0.35 )
                )
                .frame(maxWidth: .infinity, alignment: .center)
                
                Spacer()
            }
        }
    }
