0.43.0-rc.3: Clothes Line Interface

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@0.43.0-rc.3
• Cloning and building from source: git clone https://github.com/realm/SwiftLint.git && cd SwiftLint && git checkout 0.43.0-rc.3 && make install

Changes from 0.43.0-rc.2: 0.43.0-rc.2...0.43.0-rc.3

Breaking

• The command line syntax has slightly changed due to migrating from the
  Commandant command line parsing library to swift-argument-parser.
  For the most part the breaking changes are all to make the syntax more
  unix compliant and intuitive to use. For example, commands such as
  swiftlint --help or swiftlint -h now work as expected.
  The help output from various commands has greatly improved as well.
  Notably: swiftlint autocorrect was removed in favor of
  swiftlint --fix.
  Previous commands should continue to work temporarily to help with the
  transition. Please let us know if there's a command that no longer
  works and we'll attempt to add a bridge to help with its transition.

Experimental

• None.

Enhancements

• Added allows_single_line option in multiline_parameters rule
  configuration. Defaults to true. This enforces parameters in a method
  with multiple parameters to always be in different lines.

• Support relative paths in compilation databases for SwiftLint analyzer
  rules.
  JP Simard

• Add opt-in rule discouraged_assert to encourage the use of
  assertionFailure() and/or preconditionFailure() over
  assert(false).
  Otavio Cordeiro

• Add opt-in rule private_subject rule which warns against
  public Combine subjects.
  Otavio Cordeiro

• Allow configuring related USRs to skip in UnusedDeclarationRule by
  specifying a list of USRs in the related_usrs_to_skip key.
  For example you might have custom source tooling that does something
  with types conforming to a procotol even if that type is never
  explicitly referenced by other code.

Bug Fixes

• Fix typos in configuration options for file_name rule.
  advantis

• Fix violation location and misplaced corrections for some function
  references in explicit_self rule.
