Worked on upgrading the TanxSDK from version 3.7.19 to 3.7.20 within the CocoaPods/Specs repository, focusing on mobile development and SDK integration using Objective-C and Swift. The update involved adding new files and modifying existing ones to support the latest SDK features and API changes, ensuring compatibility for downstream applications. This work delivered performance improvements and addressed existing bugs within the SDK integration, resulting in enhanced runtime efficiency and stability. All modifications were tracked through detailed commit history, providing full traceability for consumer teams preparing for broader adoption of the updated SDK in their own projects and workflows.
