Asendra focused on enhancing Swift interoperability within the stripe-react-native repository, addressing a specific issue related to cross-language compatibility in iOS payment workflows. Working primarily in Objective-C, Asendra modified the STPPaymentStatus enum to use NSInteger, aligning its usage with Swift conventions and reducing potential runtime errors when bridging between Objective-C and Swift. This targeted bug fix improved the stability of the iOS bridge between the Stripe iOS SDK and React Native module, ensuring more reliable payment status handling. The work was tracked through a single, auditable commit, demonstrating a precise and maintainable approach to cross-language integration and mobile development.
