Been running into this issue with the Swiftlint plugin for a bit. Currently running a project using a PBXProj using this file structure
/AppFolder
.swiftlint.yml
/project_gen
.swiftlint.yml
.pbxproj
/Modules
___ALL MY CODE___
.swiftlint.yml
Despite this, Swiftlint still does not trigger for my project. I know that I have properly configured the plugin/settings as when I disable disable when no .swiftlint.yml present, I immediately receive swiftlint warnings/errors.
