Hi,

I have the following code, which for some reason is not working as expected. I have an .onAppear and a .task function that isn't running, which I can see isn't running because nothing is printing. Any guidance would be greatly appreciated. Thank you.

 struct ContentView: View {
    var body: some View {
        ZStack {
            switch view {
            case .view1: View1()
            case .view2: View2()
            case .view3: View3()            
            case .view4: View4()            
            case .view5: View5()
            default: SubscriptionStoreView(groupID: "")
            }
        }
            .onAppear() {
                view = .view6
                print("test 1")
            }
            .task {
                print("test")
                await refreshPurchasedProducts()
            }
    }
    
    func refreshPurchasedProducts() async {
        // Iterate through the user's purchased products.
        for await verificationResult in Transaction.currentEntitlements {
            switch verificationResult {
            case .verified(let transaction): print("verified")
            case .unverified(let unverifiedTransaction, let verificationError): print("unverified")
            default: print("default")
            }
        }
    }
}

Where is view6 in your switch statement?

Where is view defined? I'd rename it to something else: "view" is too generic, and could be mistyped to "View".

Do View1() through View5() actually display anything?

Secondly, it's .onAppear {} not .onAppear() {}.

Hi,

Thanks for your response. I changed the original View names to generic names for the purpose of this post. The view variable is defined in the ContentView struct like this:

@State var view: ScreenView

ScreenView is an enum with the different view names.

Only views 3 and 4 have code - the rest of the views/switch could be commented out.view6 is just the default view so there isn't a case for it in the switch statement. I changed .onAppear() to .onAppear. I don't see anything in the views that could possibly prevent those two functions from running.

	view = .view6
	print("test 1")
