Decision
Correct fault handling improves user feel and can return at least some of those users who could non pay for the subscription immediately for some reason. These are the virtually common mistakes when implementing purchases in an iOS app:
- SKError.Lawmaking.unknown, an unknown error;
- SKError.Code.paymentCancelled, when the user cancels the purchase;
- SKError.Code.paymentInvalid, when the payment can't exist processed.
Really, error handling and buy implementation are cumbersome processes. And then I would recommend trying Adapty SDK for iOS, which makes implementing in-app purchases easier and provides other benefits, such every bit subscription analytics, cohort analysis, a/b tests for paywalls, and server-side receipt validation.
