Non Triggering Examples

_ = Set(syntaxKinds).isDisjoint(with: commentAndStringKindsSet)

let isObjc = !objcAttributes.isDisjoint(with: dictionary.enclosedSwiftAttributes)

_ = Set(syntaxKinds).intersection(commentAndStringKindsSet)

_ = !objcAttributes.intersection(dictionary.enclosedSwiftAttributes)

Triggering Examples
