SwiftLint Files

Breaking

• Configuration.IndentationStyle moved to SwiftLintCore.IndentationStyle. Rules can now read the global indentation setting via CurrentRule.configuration.
  GandaLF2006

• Remove the deprecated allow_multiline_func option from the opening_brace rule. Use ignore_multiline_function_signatures instead.

Enhancements

• Speed up the collection_alignment rule, which read the whole file's source lines once per element of a dictionary literal.
  Brett-Best

• Compare the two operands of a comparison by walking their token streams in the identical_operands rule instead of rendering both operands to strings, so differing operands stop at the first mismatching token.

• Add #examples and #corrections macros that expand lists and dictionaries of code strings into Examples, reducing boilerplate when defining a rule's triggering/non-triggering examples and corrections. Adopt them across the built-in rules.
  ZevEisenberg

• Add allow_compact_empty_blocks option to the no_empty_block rule to allow empty blocks written compactly as {} while still flagging empty blocks with any whitespace or newlines between the braces.
  arimu1 #6839

Bug Fixes

• Add an opt-in allow_explicit_unsafe_unowned option to let the unowned_variable_capture rule accept explicit unowned(unsafe) captures.
  Yurii Bakurov #6817

• Fix line_length with ignores_urls enabled incorrectly ignoring property accesses whose member names are valid top-level domains.
  Arthur Liu #6811

• Fix baseline writing to store file locations as paths relative to the current working directory, restoring baseline portability and avoiding absolute file:// paths in generated baseline files.
  SimplyDanny #6812

• Fix correction behavior of closure_spacing rule when a closure contains only trivia (e.g. comments).
  SimplyDanny #6798 #6799

• Fix closure_end_indentation moving closing braces to column 1 in files with CRLF line endings when running swiftlint --fix.

0.65.0: Fresh Folded Fixtures

Breaking

• SwiftLint now requires Swift 6.1 or higher for development (to run tests). The executable can still be built with a Swift 6 compiler. The Swift Package Manager plugins continue to work with all versions down to Swift 5.9.

Enhancements

• SwiftLint now builds with Bazel versions 7 to 9.

Using Bazel

With bzlmod:

// Pending BCR update
bazel_dep(name = "swiftlint", version = "0.65.1", repo_name = "SwiftLint")

Without bzlmod, put this in your WORKSPACE:

Then you can run SwiftLint in the current directory with this command:

:::console
bazel run @SwiftLint//:swiftlint -- --help
