opt_in_rules:
  - array_init # Prefer using Array(seq) over seq.map { $0 } to convert a sequence into an Array.
  - attributes # Attributes should be on their own lines in functions and types, but on the same line as variables and imports.
  - closure_end_indentation # Closure end should have the same indentation as the line that started it.
  - closure_spacing # Closure expressions should have a single space inside each brace.
  - collection_alignment # All elements in a collection literal should be vertically aligned.
  - contains_over_filter_count # Prefer contains over comparing filter(where:).count to 0.
  - contains_over_filter_is_empty # Prefer contains over using filter(where:).isEmpty.
  - contains_over_first_not_nil # Prefer contains over first(where:) != nil and firstIndex(where:) != nil
  - contains_over_range_nil_comparison # Prefer contains over range(of:) != nil and range(of:) == nil.
  - convenience_type # Types used for hosting only static members should be implemented as a caseless enum to avoid instantiation.
  - empty_collection_literal # Prefer checking isEmpty over comparing collection to an empty array or dictionary literal.
  - empty_count # Prefer checking isEmpty over comparing count to zero.
  - empty_string # Prefer checking isEmpty over comparing string to an empty string literal.
  # - explicit_enum_raw_value # Enums should be explicitly assigned their raw values.
  - explicit_init # Explicitly calling .init() should be avoided.
  - fatal_error_message # A fatalError call should have a message.
  - first_where # Prefer using .first(where:) over .filter { }.first in collections.
  - for_where # where clauses are preferred over a single if inside a for.
  - function_default_parameter_at_end # Prefer to locate parameters with defaults toward the end of the parameter list.
  - identical_operands # Comparing two identical operands is likely a mistake.
  - implicit_return # Prefer implicit returns in closures.
  - last_where # Prefer using .last(where:) over .filter { }.last in collections.
  - legacy_multiple # Prefer using the isMultiple(of:) function instead of using the remainder operator (%).
  - legacy_random # Prefer using type.random(in:) over legacy functions.
  - literal_expression_end_indentation # Array and dictionary literal end should have the same indentation as the line that started it.
  - lower_acl_than_parent # Ensure definitions have a lower access control level than their enclosing parent.
  # - missing_docs # Declarations should be documented.
  - modifier_order # Modifier order should be consistent.
  - multiline_arguments # Arguments should be either on the same line, or one per line.
  - multiline_arguments_brackets # Multiline arguments should have their surrounding brackets in a new line.
  - multiline_function_chains # Chained function calls should be either on the same line, or one per line.
  - multiline_literal_brackets # Multiline literals should have their surrounding brackets in a new line.
  - multiline_parameters # Functions and methods parameters should be either on the same line, or one per line.
  - multiline_parameters_brackets # Multiline parameters should have their surrounding brackets in a new line.
  - nslocalizedstring_key # Static strings should be used as key in NSLocalizedString in order to genstrings work.
  - number_separator # Underscores should be used as thousand separator in large decimal numbers.
  - operator_usage_whitespace # Operators should be surrounded by a single whitespace when they are being used.
  - overridden_super_call # Some overridden methods should always call super.
  - pattern_matching_keywords # Combine multiple pattern matching bindings by moving keywords out of tuples.
  - reduce_into # Prefer reduce(into:_:) over reduce(_:_:) for copy-on-write types.
  - redundant_nil_coalescing # nil coalescing operator is only evaluated if the lhs is nil, coalescing operator with nil as rhs is redundant.
  - redundant_type_annotation # Variables should not have redundant type annotation.
  - sorted_first_last # Prefer using min() or max() over sorted().first or sorted().last
  - strict_fileprivate # fileprivate should be avoided.
  - syntactic_sugar # Shorthand syntactic sugar should be used, i.e. [Int] instead of Array.
  - toggle_bool # Prefer someBool.toggle() over someBool = !someBool.
  - unneeded_parentheses_in_closure_argument # Parentheses are not needed when declaring closure arguments.
  - unused_import # All imported modules should be required to make the file compile.
  - vertical_parameter_alignment_on_call # Function parameters should be aligned vertically if they're in multiple lines in a method call.
  - vertical_whitespace_closing_braces # Don't include vertical whitespace (empty line) before closing braces.
  - vertical_whitespace_opening_braces # Don't include vertical whitespace (empty line) after opening braces.
