I have been using SwiftLint for a very long time now in my iOS projects so I decided to integrate it to the Gitlab code quality flow.
This is quite easy because SwifLint can generate a Code Climate format that Gitlab understands. No need for any custom format conversion or data transformation.
To set it up in Gitlab you need to modify your
.gitlab-ci.yml file. First include the code quality template
include: - template: Code-Quality.gitlab-ci.yml
and then add a new job called
code_quality, it needs to have this exact name to match the included template
code_quality: dependencies:  stage: linting artifacts: paths: - codequality_report.json reports: codequality: codequality_report.json script: - swiftlint --reporter codeclimate > codequality_report.json tags: - iOS-arm
This works for a simple project. In my projects I usually use an iOS application project and a few smaller framework projects that the iOS application uses, so instead of
swiftlint --reporter codeclimate > codequality_report.json I call a custom shell script
