Worked on the TencentCloud/TIMSDK repository to deliver two targeted SDK upgrades focused on improving iOS development workflows. Upgraded the IM SDK to versions 8.4.6667 and 8.7.7201, removing architecture exclusions for iOS simulators and updating all platform-specific podspec files. This approach enabled broader simulator compatibility, streamlined local development, and simplified CI/CD processes for mobile teams. Leveraged Objective-C, CocoaPods, and SDK management skills to ensure seamless integration and traceable releases. The work addressed dependency alignment and improved build efficiency, allowing developers to test across more environments without friction. No bug fixes were recorded during this period, emphasizing feature delivery.
