 opt_in_rules:
-  - anyobject_protocol             # Prefer using `AnyObject` over class for class-only protocols.
-  - array_init                     # Prefer using `Array(seq)` over `seq.map { $0 }` to convert a sequence into an Array.
-  - block_based_kvo                # Prefer the new block based KVO API with keypaths when using Swift 3.2 or later.
-  - closure_spacing                # Closure expressions should have a single space inside each brace.
-  - 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`.
-  - 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_parameters               # Prefer `() ->` over `Void ->`.
-  - empty_string                   # Prefer checking `isEmpty` over comparing string to an empty string literal.
-  - empty_xctest_method            # Empty XCTest method should be avoided.
-  - explicit_init                  # Explicitly calling .init() should be avoided.
-  - fatal_error_message            # A fatalError call should have a message.
-  - file_header                    # Header comments should be consistent with project patterns.
-  - first_where                    # Prefer using `.first(where:)` over `.filter { }.first` in collections.
-  - for_where                      # `where` clauses are preferred over a single `if` inside a `for`.
-  - force_unwrapping               # Force unwrapping should be avoided.
-  - is_disjoint                    # Prefer using `Set.isDisjoint(with:)` over `Set.intersection(_:).isEmpty`.
-  - 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 (`%`).
-  - lower_acl_than_parent          # Ensure definitions have a lower access control level than their enclosing parent
-  - missing_docs                   # Declarations should be documented.
-  - object_literal                 # Prefer object literals over image and color inits.
-  - 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
-  - private_outlet                 # IBOutlets should be private to avoid leaking UIKit to higher layers.
-  - prohibited_super_call          # Some methods should not call super, e.g. `UIViewController.loadView()`
-  - sorted_first_last              # Prefer using `min()` or `max()` over `sorted().first` or `sorted().last`
-  - toggle_bool                    # Prefer `someBool.toggle()` over `someBool = !someBool`.
-  - unused_import                  # All imported modules should be required to make the file compile.
