Coin-Operated Machine RC1 Pre-release
Pre-release

We encourage you to try this pre-release version of SwiftLint. There are lots of significant changes leading up to a 0.19.0 version, which is why we've decided to share a release candidate before pushing out an official stable release.

We're especially interested in hearing feedback on:

  • the newly-reenabled caching support (hence this release's cash-related name 😉 ). We'd love to hear if the cache ever returns any incorrect/stale results.
  • the removal of Swift 2 support & Swift 2-only rules like missing_docs and valid_docs.
  • lots of new rules & bug fixes.

Installation

  • Homebrew: brew update && brew upgrade swiftlint --HEAD
  • CocoaPods: pod 'SwiftLint', '= 0.19.0-rc.1'
  • Portable/pkg: See GitHub release attachments

0.18.1: Misaligned Drum
Breaking

  • Replace YamlSwift with Yams. SwiftLint no longer includes YamlSwift. If your
    project implicitly depends on YamlSwift, you need to modify it to depend on
    YamlSwift explicitly.
    norio-nomura
    #1412

  • Yams interprets YAML more strictly than YamlSwift, so if your YAML
    configurations previously worked with SwiftLint but didn't fully conform to
    the YAML 1.2 standard, you'll need to fix those validation errors.
    For example:

    custom_rules:
  wrong_regex:
    name: "wrong regex"
    regex: "((assert|precondition)\(false)" # '\' in "" means escape sequence
  strict_regex:
    name: "strict regex"
    regex: '((assert|precondition)\(false)' # Use single quotes
Enhancements

  • Support compiling with Xcode 8.3 and Swift 3.1.
    Keith Smiley

  • Fix false positives on for_where rule and skip violation on
    complex conditions.
    Marcelo Fabri
    #1387

  • Print YAML configuration errors in locatable format compatible with Xcode's
    Issue Navigator.

0.17.0: Extra Rinse Cycle

This release brings 8 new rules, as well as important bug fixes and improvements to existing ones.
We also temporarily disabled the cache when linting until some important cache-related issues are addressed in a future version.

Breaking

  • variable_name rule (VariableNameRule) is now identifier_name
    (IdentifierNameRule) as it validates other identifiers as well.
    Marcelo Fabri
    #663

  • Fix sorted_imports rule to sort ignoring case.
    Keith Smiley
    #1185

  • Temporarily disable cache when linting. This will be re-enabled in a future
    version after important cache-related issues have been addressed.
    Marcelo Fabri

Enhancements

  • Add implicitly_unwrapped_optional opt-in rule that warns against using
    implicitly unwrapped optionals, except cases when this IUO is an IBOutlet.
    Siarhei Fedartsou
    #56

  • Performance improvements to generic_type_name, redundant_nil_coalescing,
    mark, first_where and vertical_whitespace rules.
    Marcelo Fabri

  • Add discarded_notification_center_observer rule that warns when the result
    of NotificationCenter.addObserver(forName:object:queue:using:) is not stored
    so it can be removed later.
    Marcelo Fabri
    #1062

  • Add notification_center_detachment rule that warns against an object
    removing itself from NotificationCenter in an unsafe location.
    Marcelo Fabri
    #1061

  • Accept AnyObject and NSObjectProtocol in class_delegate_protocol.
    Jon Shier
    #1261

  • Add ignores_function_declarations and ignores_comments as options to
    LineLengthRule.
    Michael L. Welles
    #598
    #975

  • Add for_where rule that validates that where is used in a for loop
    instead of a single if expression inside the loop.
    Marcelo Fabri
    #1228

  • unused_enumerated rule now warns when only the index is being used.
    You should use .indices instead of .enumerated() in this case.
    Marcelo Fabri
    #1278

  • Add ignores_case_statements as option to CyclomaticComplexityRule.
    Michael L. Welles
    #1298

  • Add correctable redundant_discardable_let rule that warns when
    let _ = foo() is used to discard a result from a function instead of
    _ = foo().
    Marcelo Fabri
    #1232

  • Accept global and local variables in implicit_getter rule.
    Marcelo Fabri

  • Add --enabled (or -e) switch to the rules CLI command, to only display
    enabled rules.
    Natan Rolnik
    #1270

  • Now nesting rule can be configured with a type and statement level.
    Hayashi Tatsuya
    #1318

  • Add explicit_type_interface opt-in rule that validates that the properties
    have an explicit type interface.
    Kim de Vos

  • Add --lenient CLI option to lint command. Facilitates running a lint task
    that doesn't fail a pipeline of other tasks.
    aaroncrespo
    #1322

  • Add fatal_error_message opt-in rule that validates that fatalError() calls
    have a message.
    Kim de Vos
    #1348

Bug Fixes

  • Fix crashes when accessing cached regular expressions when linting in
    parallel.
    JP Simard
    #1344

  • Fix a false positive on large_tuple rule when using closures.
    Marcelo Fabri
    #1234

  • Fix force_unwrap false positive for bool negation.
    Aaron McTavish
    #918

  • Fix false positive and wrong correction on number_separator rule.
    Marcelo Fabri
    #1242

  • Retain closure parameter types when they are specified during autocorrect.
    Allen Zeng
    #1175

  • Fix redundant_void_return matches if return type starts with Void~.
    Hayashi Tatsuya

  • Ignore unused_closure_parameter rule on closures that are called inline.
    Marcelo Fabri
    #1161

  • Disable valid_docs and missing_docs rules when running in Swift 2.3 or
    later as they have not been updated to work with those versions of Swift.
    Both rules are now opt-in because of this.
    JP Simard
    #728

  • Fix false positive on large_tuple rule when using generics inside a tuple.
    Marcelo Fabri
    #1257

  • Make ASTRule default implementation to navigate through the substructure
    even if its children are from a different kind. This fixes some violations not
    being reported in some contexts.
    Marcelo Fabri
    #1237

  • Reimplement switch_case_on_newline rule to be an ASTRule and be more
    reliable, fixing some false negatives and false positives.
    Marcelo Fabri
    #1268

  • Fix closure_end_indentation rule false positive when using single-line
    closures.
    Marcelo Fabri
    #1216

  • Fix todo rule messages when the comment is not on a new line.
    Marcelo Fabri
    #1304

  • Fix false negative on unused_closure_parameter rule.
    Hayashi Tatsuya

  • Fix checkstyle report format.
