SwiftLintPlugin

A Swift Package Plugin for SwiftLint that will run SwiftLint on build time and show errors & warnings in Xcode.

Note There now is an official version in the SwiftLint repo! Though this package will still be maintained and updated since it brings the benefit of being a smaller repository and therefore faster to download as a dependency

Add to Package

First add a dependency from this package:

dependencies: [
    // ...
    .package(url: "https://github.com/lukepistrol/SwiftLintPlugin", from: "0.2.2"),
]

Then add it to your targets as a plugin:

targets: [
    .target(
        name: "YOUR_TARGET",
        dependencies: [],
        plugins: [
            .plugin(name: "SwiftLint", package: "SwiftLintPlugin")
        ]
    ),
]

Add to Project

Starting with Xcode 14, plugins can also work on Xcode Project's targets. To do so, simply add this package to your SPM dependencies in Xcode. After that open your target's settings > Build Phases and add SwiftLint to Run Build Tool Plug-ins like shown below:

You may need to enable & trust the plugin before you can actually run it during builds.

Fix Warnings

As of version 0.1.0 this package also includes a command plugin which can be called on any target.

1. Select a project or package in the project navigator.
2. Richt-click and select SwiftLintFix.
   • alternatively you can select File > Packages > SwiftLintFix.
3. Choose the target(s) to run the swiftlint --fix command on.

Run on CI

Important to notice is that when building a package/project on any CI provider (e.g. GitHub Actions) it is mandatory to pass the -skipPackagePluginValidation flag to the xcodebuild command. This will skip the validation prompt which in Xcode looks like this:

Example

xcodebuild  \
    -scheme "$SCHEME" \
    -destination "$PLATFORM" \
    -skipPackagePluginValidation \ # this is mandatory
    clean build

If you need to disable linting (for release/app store builds), you can setDISABLE_SWIFTLINT environment variable
