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

Adds NSError to the list of types in discouraged_direct_init.
jszumski
#4508
Fix SwiftLint support on Xcode Cloud.
JagCesar
westerlund
#4484
Add no_magic_numbers rule to avoid "Magic Numbers".
Henrik Storch
#4031
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.
JP Simard
#4031
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
swiftlang/swift#51036 for more info.

  #2915
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 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
Add library_content_provider file type to file_types_order rule
to allow LibraryContentProvider to be ordered independent from main_type.
dahlborn
Add test_parent_classes option to test_case_accessibility rule, which
allows detection in subclasses of XCTestCase.
Martin Redington
#4200
Add a new shorthand_optional_binding 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
Disregard whitespace differences in identical_operands rule. That is, the rule
now also triggers if the left-hand side and the right-hand side of an operation
only differ in trivia.
SimplyDanny
Print violations in realtime if --progress and --output are both set.
JP Simard
Update for_where rule, adding a new configuration
allow_for_as_filter to allow using for in with a single if inside
when there's a return statement inside the if's body.
Marcelo Fabri
#4040
quick_discouraged_call, quick_discouraged_focused_test and
quick_discouraged_pending_test rules now trigger on subclasses of
QuickSpec.
Marcelo Fabri
#4420
The type_name rule now validates protocol declarations by default.
You can opt-out by using the validate_protocols key in your configuration:
```
type_name:
  validate_protocols: false
```
Marcelo Fabri
#4430
Report how much memory was used when --benchmark is specified.
JP Simard

Bug Fixes

Respect validates_start_with_lowercase option when linting function names.

#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.

#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.
JP Simard
Make nsobject_prefer_isequal rule work for nested @objc classes. Also consider
the @objcMembers annotation.
SimplyDanny
Print fixed content at most once to STDOUT.
SimplyDanny
#4211
Fix fatal error when content given via STDIN is corrected in the
trailing_newline rule.
SimplyDanny
#4234
Fix false-positives from multiline_arguments_brackets when a function call has a
single line trailing closure.
