Worked on the stripe-react-native repository to enhance Swift interoperability within the iOS bridge, focusing on improving cross-language compatibility in payment workflows. Addressed a specific bug by updating the STPPaymentStatus enum to use NSInteger instead of NSUInteger, aligning Objective-C code with Swift expectations and reducing potential runtime errors related to payment status handling. The solution was implemented in Objective-C, leveraging expertise in iOS development and Swift interoperability. All changes were tracked through a single, auditable commit linked to the relevant issue, ensuring clear traceability and facilitating future maintenance. No new features were added during this period, with efforts concentrated on stability.
