XCLint

Xcode project linting

This project is still pretty young, and has rough edges. However, it kinda works! So, please do give it a shot.

Installation

XCLint is available as both a commandline tool and a library.

Tool:

brew tap mattmassicotte/XCLint https://github.com/mattmassicotte/XCLint.git
brew install xclint

Package:

dependencies: [
    .package(url: "https://github.com/mattmassicotte/XCLint", branch: "main")
],
targets: [
    .testTarget(name: "MyTarget", dependencies: ["XCLinting"]),
]

Tool Usage

Just run the xclint binary in your project directory. Check out its -h flag for more usage.

# cd my/project
# xclint

This will run a default set of rules. But, you can customize its behavior with a .xclint.yml file. The basic structure borrows a lot from SwiftLint.

# Some rules may not be appropriate for all projects. You must opt-in those.
opt_in_rules:
  - embedded_build_setting    # checks for build settings in the project file
  - groups_sorted             # checks that all group contents are alphabetically sorted
  - implicit_dependencies     # checks for any schemes that have "Find Implicit Dependencies" enabled
  - targets_use_xcconfig      # checks for any targets without a XCConfig file set
  - projects_use_xcconfig     # checks for any projects without a XCConfig file set
  - shared_scheme_skips_tests # checks for any shared schemes that have disabled tests
  - shared_schemes            # checks that all targets have a shared scheme present

# Other rules make sense for all projects by default. You must opt-out of those.
disabled_rules:
  - build_files_ordered       # checks that the ordering of techincally-unordered collections Xcode writes out is preserved
  - validate_build_settings   # checks that build settings have valid values
  - relative_paths            # checks for any absolute file references

Alternatives

I was kind of hoping that some else had built something like this. And they have! However, none of the things I found are maintained any more.

Contributing and Collaboration

I'd love to hear from you! Get in touch via mastodon, an issue, or a pull request.

I prefer collaboration, and would love to find ways to work together if you have a similar project.

I prefer indentation with tabs for improved accessibility. But, I'd rather you use the system you want and make a PR than hesitate because of whitespace.
