Experimental

Enhancements

  Swift 5.7+ features should now be parsed more accurately.
  We've also measured an improvement in lint times of up to 15%.
  This should also fix some deployment issues where the exact version of the
  internal SwiftSyntax parser needed to be available.
  If you notice any unexpected changes to lint results, please file an issue on
  the SwiftLint issue tracker. We can look into it and if it's a SwiftSyntax
  parser regression we can re-file it upstream.

• The "body length" family of rules have changed how they calculate body
  line count to be significantly more correct and intuitive. However,
  this is likely to require adjustments to your configuration or disable
  commands to account for the changes.
  JP Simard

• Add ability to filter rules for generate-docs subcommand.
  kattouf

• Add new excludes_trivial_init configuration for missing_docs rule
  to exclude initializers without any parameters.
  Marcelo Fabri
  #4107

• Add new ns_number_init_as_function_reference rule to catch NSNumber.init
  and NSDecimalNumber.init being used as function references since it
  can cause the wrong initializer to be used, causing crashes. See
  apple/swift#51036 for more info.
  Marcelo Fabri

• Add accessibility_trait_for_button rule to warn if a SwiftUI
  View has a tap gesture added to it without having the button or
  link accessibility trait.
  Ryan Cole

• Add methods from SE-0348 to UnusedDeclarationRule.
  JP Simard

• Include the configured bind_identifier in self_binding violation
  messages.
  JP Simard

• The self_binding rule now catches shorthand optional bindings (for example

• Add library_content_provider file type to file_types_order rule

• Use SwiftSyntax instead of SourceKit to determine if a file has parser errors

  • Computed properties (e.g. var i: Int { MyType.myVar ) -> var i: Int { Self.myVar })
  • Constructor calls (e.g. MyType() -> Self())

0.50.0-rc.3: Artisanal Clothes Pegs

This is a prerelease version. It won't be published to Homebrew or CocoaPods. But there are many other ways to install:

• Downloading the attached SwiftLint.pkg installer and launching it
• Downloading the attached portable_swiftlint.zip archive, extracting it and moving the binary from portable_swiftlint/swiftlint to /usr/local/bin or elsewhere in your PATH
• Using Mint: mint install realm/SwiftLint@0.50.0-rc.3
• Cloning and building from source: git clone https://github.com/realm/SwiftLint.git && cd SwiftLint && git checkout 0.50.0-rc.3 && make install
• Docker: docker run -it -v `pwd`:`pwd` -w `pwd` ghcr.io/realm/swiftlint:0.50.0-rc.3
• Bazel: See instructions at the bottom

Breaking

• SwiftLint now requires Swift 5.7 or higher to build.
  JP Simard

• Exclude weak_delegate rule from autocorrection due to behavioral changes
  leading to potential undefined behavior or bugs.
  SimplyDanny
  #3577

• The anyobject_protocol rule is now deprecated and will be completely removed
  in a future release because it is now handled by the Swift compiler.
  JP Simard

Experimental

• None.

Enhancements

• SwiftSyntax libraries have been updated from the previous 5.6 release and now
  use the new parser written in Swift.
  Swift 5.7+ features should now be parsed more accurately.
  We've also measured an improvement in lint times of up to 15%.
  This should also fix some deployment issues where the exact version of the
  internal SwiftSyntax parser needed to be available.
  If you notice any unexpected changes to lint results, please file an issue on
  the SwiftLint issue tracker. We can look into it and if it's a SwiftSyntax
  parser regression we can re-file it upstream.

  #4200

• Add a new if_let_shadowing opt-in rule that triggers in Swift 5.7 when a
  shadowing optional binding is created in an if- or guard-statement.
  SimplyDanny
  #4202

• Use SwiftSyntax instead of SourceKit to determine if a file has parser errors
  before applying corrections. This speeds up corrections significantly when
  none of the rules use SourceKit.
  JP Simard

• Add Swift Package Build Tool Plugin with support for Swift Packages
  and Xcode projects.
  Johannes Ebeling
  #3679
  #3840

• Make private_unit_test rule correctable.
  SimplyDanny

Bug Fixes

• Respect validates_start_with_lowercase option when linting function names.
  Chris Brakebill
  #2708

• Do not report variables annotated with @NSApplicationDelegateAdaptor and
  @WKExtensionDelegateAdaptor in weak_delegate rule.
  Till Hainbach
  #3598
  #3611

• Fix false-positives related to the willMove lifecycle method in
  type_contents_order rule.
  SimplyDanny
  #3478

• Do no longer autocorrect usage of NSIntersectionRect in legacy_nsgeometry_functions
  rule.
  SimplyDanny
  #3703

• Fix Analyzer rules in Xcode 14.
  SimplyDanny
  #4208

• Add column for SourceKit usage to rules command.

Using Bazel

Put this in your WORKSPACE:

WORKSPACE

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

http_archive(
    name = "build_bazel_rules_apple",
    sha256 = "90e3b5e8ff942be134e64a83499974203ea64797fd620eddeb71b3a8e1bff681",
    url = "https://github.com/bazelbuild/rules_apple/releases/download/1.1.2/rules_apple.1.1.2.tar.gz",
)

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

)

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

0.49.1: Buanderie Principale

Note: The default branch for the SwiftLint git repository was renamed from
master to main on September 1st. Please update any code or automation
accordingly.

Breaking

• None.

Experimental

• None.

Enhancements

• Add new self_binding opt-in rule to enforce that self identifiers are
  consistently re-bound to a common identifier name. Configure bind_identifier
  to the name you want to use. Defaults to self.
  JP Simard
  #2495

• Add --output option to lint and analyze commands to write to a file instead
  of to stdout.
  JP Simard
  #4048

• Add --progress flag to lint and analyze commands to show a live-updating
  progress bar instead of each file being processed.
  JP Simard

• --fix now works with --use-stdin, printing the output to to STDOUT instead
  of crashing.
  SimplyDanny
  #4127

Bug Fixes

• Migrate empty_xctest_method rule to SwiftSyntax fixing some false positives.
  SimplyDanny
  #3647
  #3691

• Fix false positives in redundant_discardable_let when using
  async let.
  Martin Hosna
  #4142

• Consistently print error/info messages to stderr instead of stdout,
  which wasn't being done for errors regarding remote configurations.
