The issues related to issues/5556, issues/5557, issues 5558, and issues/5559 have been closed. But I still have a question, using https://github.com/aws/aws-iot-device-sdk-swift Does this library explicitly address such issues? If it cannot be clearly resolved, switching libraries is useless to me. Another important point is that AWS IoT device SDK Swift is currently in the DEVELOPER PREVIEW stage and cannot meet the requirements for online release versions. So I still hope to solve the problem in aws-sdk-ios.
