Description
Running the Swiftgen plugin in an Xcode Cloud build fails with the following errors:
Plug-in ended with non-zero exit code: 64)
xcodebuild: error: Failed to copy build products to test products file with error: The file “Products” couldn’t be opened because there is no such file.
It seems like there was an error running SwiftGen.
