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.

• 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
