Using #SwiftLint's Swift Package Manager plugins directly can cause dependency conflicts and extended compile times.
Therefore, I recommend to pull the plugins from https://github.com/SimplyDanny/SwiftLintPlugins instead.
Among others things, this resolves the previously mentioned problems due to the limited scope of the dedicated Swift package.
All the code in the plugin repository will stay in sync with the main #SwiftLint repository and so will the releases.
Enjoy linting!
