# ContainsComparator An object that determines whether the value of sequence property contains the specified value. ``` final class ContainsComparator where Property : EntityProperty, PropertyType : _IntentValue, PropertyType : Sendable, InputType : _IntentValue ``` ## Topics ### Creating a comparator [`init(mappingTransform: (InputType) -> ComparatorMappingType)`](/documentation/AppIntents/ContainsComparator/init(mappingTransform:)-xvws) Declares support for the `contains` operator between a `AttributedString` property and user-supplied values. [`init(mappingTransform: (InputType) -> ComparatorMappingType)`](/documentation/AppIntents/ContainsComparator/init(mappingTransform:)-3xuvt) Declares support for the `contains` operator between a `String` property and user-supplied values. [`init(mappingTransform: (InputType) -> ComparatorMappingType)`](/documentation/AppIntents/ContainsComparator/init(mappingTransform:)-7rx55) Declares support for the `contains` operator between an optional `Array` property and user-supplied values. [`init(withResolvers: () -> Spec, mappingTransform: (InputType) -> ComparatorMappingType)`](/documentation/AppIntents/ContainsComparator/init(withResolvers:mappingTransform:)-4482k) Declares support for the `contains` operator between an `Array` property and user-supplied values. ### Initializers [`init(mappingTransform: (InputType) -> ComparatorMappingType)`](/documentation/AppIntents/ContainsComparator/init(mappingTransform:)-7ya5) Declares support for the `contains` operator between a `AttributedString?` property and user-supplied values.
