Rule explicit_self does not report violations

Describe the bug

I'm running swiftlint analyze with rule explicit_self enabled in my project:

xcodebuild clean -workspace XYZ.xcworkspace -scheme XYZ
xcodebuild -workspace XYZ.xcworkspace -scheme XYZ >xcodebuild.log
swiftlint analyze --compiler-log-path xcodebuild.log

Snippet from .swiftlint.yml:

analyzer_rules:
 - explicit_self

and get "0 violations found", although there are a few.

The same .swiftint.yml file works in a newly created dummy project where I've added an intentional violation. I am unable to share the project code, unfortunately, is there anything I can do help narrow this down?

Swiftlint version: 0.37.0, installed via homebrew
Xcode version: 11.2.1

If you can create a separate project that reproduces the issue that you can share, that will go a long way towards helping identify why this isn't working for you.

I tried that initially but was unable to reproduce the issue at the time.

I did however manage to spend some more time on this today and was able to find two unrelated issues surrounding the analyzer and explicit_self which I'll post separately.

Thanks for investigating. Looking forward to seeing what you found.
