StoreKit StoreView restore purchase listener

Question

I use StoreKit's StoreView to buy in-app purchases. The purchase is working in the simulator, but how can I restore purchases? I did not find a restore handler, there is only a onInAppPurchaseCompletion but I'm missing a onRestorePurchaseCompletion or similar.

This is how it looks

This is my code:

  StoreView(ids: ["my.product.id"])
   .storeButton(.visible, for: .restorePurchases)
   .storeButton(.hidden, for: .cancellation)
   .onInAppPurchaseCompletion { product, result in
    if case .success(.success(let transaction)) = result {
       print("Purchased successfully: \(transaction.signedDate)")
       isPremium = true
    } else {
       print("Something went wrong")
    }
  }

Answer 1

When using StoreKit 2 UI the Restore Purchases button behaves the same as calling AppStore.sync()

This refetches the entitlements from App Store. There is thus no handler for it provided, as any missing entitlements should be added as a successfully completed purchase on the onInAppPurchaseCompletion handler. Additionally, any missing entitlements will also be added into the Transaction.currentEntitlements after user clicks the button and authenticates on the App Store.

You can read more about this behaviour in this post and here.
