Purchase method's completion handler is not called

[ArtSabintsev]

Describe the bug Neither the success nor the failure are called. I've completed a successful purchase many times, but I can't do anything after the purchase has completed.

To Reproduce My sample code.

    static func removeAds() {
        let iap = InAppPurchase.default
        iap.addTransactionObserver()
        iap.purchase(productIdentifier: "1") { result in
            switch result {
            case .success(let state):
                print("SUCCESS: \(state)")
                UserDefaults.standard.removeAds = true
            case .failure(let error):
                print(error)
            }
        }
        iap.removeTransactionObserver()
    }

Is something wrong my code?

The In-App-Purchase transaction should be always observed after your app launched. If you have no special reason, I recommend to call addTransactionObserver in didFinishLaunchingWithOptions of AppDelegate, and not to remove the observer during your app running.

Thanks for the sample code to help me understand your issue!

No problem! Thank you, I’ll try in the morning!

Do I need to retain IAP.default in the AppDelegate, or does the Singleton self retain after calling it once?

The latter is right. InAppPurchase.default is a shared singleton instance.

ok, that fixed it - thank you!
