Failing to load coverage
roballie opened this issue · comments
This might be because of how my workspace is setup, but whenever I run slather I get error: Failed to load coverage .... no coverage data found. I know there is coverage, because if I open the xcresults, I see all the coverage data.
My project has a testing harness workspace that contains all the frameworks to be tested which are pulled in a submodules. The framework projects themselves have the tests in them, but the testing harness contains a project that has all the test plans.
Here is the full error message, any thoughts?

Same issue for me, starting from Xcode 14.3.x
I'm using a fastlane file with slather configuration
Do you have some idea?
I am also experiencing this issue. Would love to hear how I can be of help with debugging this issue.
Have found a solution now?
Not sure what @roballie is seeing, but I think everyone else posting here is seeing #541
That is a change in xcode 14.3+ upstream of slather that can't be fixed in slather; you'll need to rebuild all of your apps and upstream dependencies with xcode 14.3+. #541 (comment)
