InAppPurchaseManager

This is a general singleton In-App Purchase Manager that can be shared between apps or mutiple places in one app. You need to have a case for each ProductID

enum ProductId:String, CaseIterable {
    // User defined and must be the same as AppStoreConnect
    case Prod1 = "com.Prod1"
    case Prod2 = "com.Prod2"
    case Prod3 = "com.Prod3"
}

How to use

Below is how you can add InAppPurchaseManager to your app.

1. Just add InAppPurchaseManager.swift to your project
2. Fetch Produts as soon as possible. We recommend the following in AppDelegate.swift

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
         InAppPurchaseManager.shared.startTransactionListener()
        Task{
            await InAppPurchaseManager.shared.fetchProducts()
        }
        ....
        return true
   }
