  trailing_whitespace_permissive:
    name: Trailing Whitespace (excluding whitespace-only lines)
    # This will only catch some trailing whitespace due to swiftlint's custom regex
    # implementation and how it filters for match_kinds.
    # This alternative regex will catch more (but still not all) cases:
    # "\S+[\S\t\f\p{Z}]+[\t\f\p{Z}]+\n" but it is much less performant.
    # Examples that won't be caught:
    # closing brace by itself followed by space (not caught by either regex),
    # func declaration followed by space after the opening brace (would be caught by
    # less performant regex)
    regex: '\S+[\t\f\p{Z}]+\n'
