I am trying to use codecov with my swift Xcode project. It was working fine until yesterday but is throwing error at llvm-cov show step in the bash uploader script today. Tried to replicate it with a basic xcode project setup in my local machine and still getting the same error.
bash <(curl -s https://codecov.io/bash)
