Cannot override 'paymentQueue' which has been marked unavailable in 0.16.3

I'm trying to update to 0.16.3 so that hopefully a crash I am experiencing related to price locale will be fixed. However Xcode it failing for `Cannot override 'paymentQueue' which has been marked unavailable` on this line which looks like it shouldn't be commented out ?

```swift
// #if os(iOS) && !targetEnvironment(macCatalyst)
func paymentQueue(_ queue: SKPaymentQueue, shouldAddStorePayment payment: SKPayment, for product: SKProduct) -> Bool {
return shouldAddStorePaymentHandler?(payment, product) ?? false
}
// #endif
```
