SwiftLint doesn't produce any warnings while code has a lot of of them

Question

I've installed SwiftLint 0.53.0 into my pet project:

export PATH="$PATH:/opt/homebrew/bin"
if which swiftlint > /dev/null; then
    swiftlint --fix
else
  echo "Error! Swiftlint is not installed"
  exit 1
fi

It starts linting:

But it doesn't produce any output while I definitely know it should.

.swiftlint.yml contains correct project path and reporter option set to "Xcode".

I tried changing it to "html" but it doesn't produce any html files.

Of course, there's --fix option activated but there are lint warnings that it can't automatically fix. So they definitely should be shown as warnings.

Please help me. I've searched a lot about this issue but unfortunately didn't find anything.

Thank you.

SwiftLint will not generate any warning in Xcode if you run it with the --fix argument.

The recommended way in the documentation to handle this is to run SwiftLint twice

swiftlint --fix && swiftlint

Then the second run will generate the warnings in Xcode for you.
