Breaking

• None.

Experimental

• None.

Enhancements

• Make severity for unallowed symbols configurable. The option name is unallowed_symbols_severity. It accepts the two values warning and error (default) as usual.
  SimplyDanny

• Mention a rule's identifier in the console message that is printed when the rule's associated configuration entry contains invalid values.
  SimplyDanny

• Silence xct_specific_matcher rule on "one argument asserts" if there are potential types or tuples involved in the comparison as types and tuples do not conform to Equatable.
  SimplyDanny #4990

• Add grouping option to the sorted_imports rule allowing to sort groups of imports defined by their preceding attributes (e.g. @testable, @_exported, ...).
  hiltonc

• Add new --silence-deprecation-warnings flag that silences deprecation warnings that would otherwise be printed to the console.
  SimplyDanny #4989

• Do not trigger redundant_self_in_closure rule when another idenfier x in scope shadows the field accessed by self.x to avoid semantical changes.
  SimplyDanny #5010

• Rewrite todo rule with SwiftSyntax.
  woxtu

• Adds an unneeded_synthesized_initializer rule, based on swift-format's UseSynthesizedInitializer rule, which warns when a defined default or memberwise initializer would have been automatically synthesized.
  Martin Redington

Bug Fixes

• The option validates_start_with_lowercase can now be disabled by setting it to off.
  SimplyDanny #5036

• Do not trigger prefer_self_in_static_references rule on typealias declarations in classes.
  SimplyDanny #5009

• Do not trigger prefer_self_in_static_references rule on collection types in classes, but on initializers like [C]() in all types.
  SimplyDanny #5042

• Fix false positives on redundant_objc_attribute rule for enums and private members.
  Martin Redington #4633

• Fix autocorrect for CGIntersectionRect in legacy_cggeometry_functions rule.
  Haoocen #5023

• Fix false positives on sorted_first_last rule when first/last have a predicate.
  woxtu #3023

• Work around dyld warning about duplicate SwiftSyntax classes with Xcode 15 betas.

Using Bazel

With bzlmod:

// Pending BCR update
bazel_dep(name = "swiftlint", version = "0.52.3", repo_name = "SwiftLint")

Without bzlmod, put this in your WORKSPACE:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "build_bazel_rules_apple",
    sha256 = "9e26307516c4d5f2ad4aee90ac01eb8cd31f9b8d6ea93619fc64b3cbc81b0944",
    url = "https://github.com/bazelbuild/rules_apple/releases/download/2.2.0/rules_apple.2.2.0.tar.gz",
)

load(
    "@build_bazel_rules_apple//apple:repositories.bzl",
    "apple_rules_dependencies",
)

apple_rules_dependencies()

load(
    "@build_bazel_rules_swift//swift:repositories.bzl",
    "swift_rules_dependencies",
)

swift_rules_dependencies()

load(
    "@build_bazel_rules_swift//swift:extras.bzl",
    "swift_rules_extra_dependencies",
)

swift_rules_extra_dependencies()

http_archive(
    name = "SwiftLint",
    sha256 = "20c09504184d2496a4b40bc6f77a03d443fe4ba79b4bbbab61382bc5241d24aa",
    url = "https://github.com/realm/SwiftLint/releases/download/0.52.3/bazel.tar.gz",
)

load("@SwiftLint//bazel:repos.bzl", "swiftlint_repos")

swiftlint_repos()

load("@SwiftLint//bazel:deps.bzl", "swiftlint_deps")

swiftlint_deps()

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

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