Determination
Correct error handling improves user experience and tin can render at least some of those users who could not pay for the subscription immediately for some reason. These are the most mutual mistakes when implementing purchases in an iOS app:
- SKError.Code.unknown, an unknown error;
- SKError.Code.paymentCancelled, when the user cancels the purchase;
- SKError.Code.paymentInvalid, when the payment can't be processed.
Really, error treatment and purchase implementation are cumbersome processes. So I would recommend trying Adapty SDK for iOS, which makes implementing in-app purchases easier and provides other benefits, such equally subscription analytics, cohort analysis, a/b tests for paywalls, and server-side receipt validation.
