Generating Codecov reports with Xcode Project - xcode

Question

Codecov is failing to process the code coverage reports. It appears to upload successfully but gives the error: "There was an error processing coverage reports".
My project is already successfully integrated with Travis-CI. I am just trying to post my code coverage reports to Codecov.
It is a public project so it doesn't need a token for Codecov.
I have nothing but a sample test in this project so far. I am trying to make sure this integration works before moving forward.
I have enabled code coverage in the schema editor and when I run the tests in Xcode I can see it is generating code coverage reports.
Do I need to integrate with Slather to format my reports before sending them to Codecov?
Could the paths to my files be wrong?

All I am seeing on my Codecov page is "There was an error processing coverage reports".
