Creating coverage report (from here) produces calling to xcrun utility: here
But this calling doesn't depend on xcode version, made in plugin configuration.
Default xcode-select -p may be different than using in build.gradle file.
And if default llvm-cov older than proper utility, it cause error like Failed to load coverage: Unsupported coverage format version
Maybe CoverageReport package should be parameterized by path-to-xcrun (like in this section)?
